## [2025-04-17] Added Content Source Selection for Markdown Generation
|
||||
|
||||
**Feature:** Configurable content source for markdown generation
|
||||
|
||||
**Changes Made:**
|
||||
1. Added `content_source: str = "cleaned_html"` parameter to `MarkdownGenerationStrategy` class
|
||||
2. Updated `DefaultMarkdownGenerator` to accept and pass the content source parameter
|
||||
3. Renamed the `cleaned_html` parameter to `input_html` in the `generate_markdown` method
|
||||
4. Modified `AsyncWebCrawler.aprocess_html` to select the appropriate HTML source based on the generator's config
|
||||
5. Added `preprocess_html_for_schema` import in `async_webcrawler.py`
|
||||
|
||||
**Implementation Details:**
|
||||
- Added a new `content_source` parameter to specify which HTML input to use for markdown generation
|
||||
- Options include: "cleaned_html" (default), "raw_html", and "fit_html"
|
||||
- Used a dictionary dispatch pattern in `aprocess_html` to select the appropriate HTML source
|
||||
- Added proper error handling with fallback to cleaned_html if content source selection fails
|
||||
- Ensured backward compatibility by defaulting to "cleaned_html" option
|
||||
|
||||
**Files Modified:**
|
||||
- `crawl4ai/markdown_generation_strategy.py`: Added content_source parameter and updated the method signature
|
||||
- `crawl4ai/async_webcrawler.py`: Added HTML source selection logic and updated imports
|
||||
|
||||
**Examples:**
|
||||
- Created `docs/examples/content_source_example.py` demonstrating how to use the new parameter
|
||||
|
||||
**Challenges:**
|
||||
- Maintaining backward compatibility while reorganizing the parameter flow
|
||||
- Ensuring proper error handling for all content source options
|
||||
- Making the change with minimal code modifications
|
||||
|
||||
**Why This Feature:**
|
||||
The content source selection feature allows users to choose which HTML content to use as input for markdown generation:
|
||||
1. "cleaned_html" - Uses the post-processed HTML after scraping strategy (original behavior)
|
||||
2. "raw_html" - Uses the original raw HTML directly from the web page
|
||||
3. "fit_html" - Uses the preprocessed HTML optimized for schema extraction
|
||||
|
||||
This feature provides greater flexibility in how users generate markdown, enabling them to:
|
||||
- Capture more detailed content from the original HTML when needed
|
||||
- Use schema-optimized HTML when working with structured data
|
||||
- Choose the approach that best suits their specific use case
|
||||
## [2025-04-17] Implemented High Volume Stress Testing Solution for SDK
|
||||
|
||||
**Feature:** Comprehensive stress testing framework using `arun_many` and the dispatcher system to evaluate performance, concurrency handling, and identify potential issues under high-volume crawling scenarios.
|
||||
|
||||
**Changes Made:**
|
||||
1. Created a dedicated stress testing framework in the `benchmarking/` (or similar) directory.
|
||||
2. Implemented local test site generation (`SiteGenerator`) with configurable heavy HTML pages.
|
||||
3. Added basic memory usage tracking (`SimpleMemoryTracker`) using platform-specific commands (avoiding `psutil` dependency for this specific test).
|
||||
4. Utilized `CrawlerMonitor` from `crawl4ai` for rich terminal UI and real-time monitoring of test progress and dispatcher activity.
|
||||
5. Implemented detailed result summary saving (JSON) and memory sample logging (CSV).
|
||||
6. Developed `run_benchmark.py` to orchestrate tests with predefined configurations.
|
||||
7. Created `run_all.sh` as a simple wrapper for `run_benchmark.py`.
|
||||
|
||||
**Implementation Details:**
|
||||
- Generates a local test site with configurable pages containing heavy text and image content.
|
||||
- Uses Python's built-in `http.server` for local serving, minimizing network variance.
|
||||
- Leverages `crawl4ai`'s `arun_many` method for processing URLs.
|
||||
- Utilizes `MemoryAdaptiveDispatcher` to manage concurrency via the `max_sessions` parameter (note: memory adaptation features require `psutil`, not used by `SimpleMemoryTracker`).
|
||||
- Tracks memory usage via `SimpleMemoryTracker`, recording samples throughout test execution to a CSV file.
|
||||
- Uses `CrawlerMonitor` (which uses the `rich` library) for clear terminal visualization and progress reporting directly from the dispatcher.
|
||||
- Stores detailed final metrics in a JSON summary file.
|
||||
|
||||
**Files Created/Updated:**
|
||||
- `stress_test_sdk.py`: Main stress testing implementation using `arun_many`.
|
||||
- `benchmark_report.py`: (Assumed) Report generator for comparing test results.
|
||||
- `run_benchmark.py`: Test runner script with predefined configurations.
|
||||
- `run_all.sh`: Simple bash script wrapper for `run_benchmark.py`.
|
||||
- `USAGE.md`: Comprehensive documentation on usage and interpretation (updated).
|
||||
|
||||
**Testing Approach:**
|
||||
- Creates a controlled, reproducible test environment with a local HTTP server.
|
||||
- Processes URLs using `arun_many`, allowing the dispatcher to manage concurrency up to `max_sessions`.
|
||||
- Optionally logs per-batch summaries (when not in streaming mode) after processing chunks.
|
||||
- Supports different test sizes via `run_benchmark.py` configurations.
|
||||
- Records memory samples via platform commands for basic trend analysis.
|
||||
- Includes cleanup functionality for the test environment.
|
||||
|
||||
**Challenges:**
|
||||
- Ensuring proper cleanup of HTTP server processes.
|
||||
- Getting reliable memory tracking across platforms without adding heavy dependencies (`psutil`) to this specific test script.
|
||||
- Designing `run_benchmark.py` to correctly pass arguments to `stress_test_sdk.py`.
|
||||
|
||||
**Why This Feature:**
|
||||
The high volume stress testing solution addresses critical needs for ensuring Crawl4AI's `arun_many` reliability:
|
||||
1. Provides a reproducible way to evaluate performance under concurrent load.
|
||||
2. Allows testing the dispatcher's concurrency control (`max_session_permit`) and queue management.
|
||||
3. Enables performance tuning by observing throughput (`URLs/sec`) under different `max_sessions` settings.
|
||||
4. Creates a controlled environment for testing `arun_many` behavior.
|
||||
5. Supports continuous integration by providing deterministic test conditions for `arun_many`.
|
||||
|
||||
**Design Decisions:**
|
||||
- Chose local site generation for reproducibility and isolation from network issues.
|
||||
- Utilized the built-in `CrawlerMonitor` for real-time feedback, leveraging its `rich` integration.
|
||||
- Implemented optional per-batch logging in `stress_test_sdk.py` (when not streaming) to provide chunk-level summaries alongside the continuous monitor.
|
||||
- Adopted `arun_many` with a `MemoryAdaptiveDispatcher` as the core mechanism for parallel execution, reflecting the intended SDK usage.
|
||||
- Created `run_benchmark.py` to simplify running standard test configurations.
|
||||
- Used `SimpleMemoryTracker` to provide basic memory insights without requiring `psutil` for this particular test runner.
|
||||
|
||||
**Future Enhancements to Consider:**
|
||||
- Create a separate test variant that *does* use `psutil` to specifically stress the memory-adaptive features of the dispatcher.
|
||||
- Add support for generated JavaScript content.
|
||||
- Add support for Docker-based testing with explicit memory limits.
|
||||
- Enhance `benchmark_report.py` to provide more sophisticated analysis of performance and memory trends from the generated JSON/CSV files.

|
||||
2. Updated `run_benchmark.py` argument handling to correctly pass all relevant custom parameters (including `--stream`, `--monitor-mode`, etc.) to `stress_test_sdk.py`.
|
||||
3. (Assuming changes in `benchmark_report.py`) Applied dark theme to benchmark reports for better readability.
|
||||
4. (Assuming changes in `benchmark_report.py`) Improved visualization code to eliminate matplotlib warnings.

|
||||
* Identified the fundamental misunderstanding where `--workers` was used incorrectly.
|
||||
* Refactored `stress_test_sdk.py` to accept `--max-sessions` and configure the `MemoryAdaptiveDispatcher`'s `max_session_permit` accordingly.
|
||||
* Updated `run_benchmark.py` argument parsing and command construction to use `--max-sessions`.
|
||||
* Updated `TEST_CONFIGS` in `run_benchmark.py` to use `max_sessions`.
|
||||
|
||||
2. **Argument Handling (`run_benchmark.py`)**:
|
||||
* Improved logic to collect all command-line arguments provided to `run_benchmark.py`.
|
||||
* Ensured all relevant arguments (like `--stream`, `--monitor-mode`, `--port`, `--use-rate-limiter`, etc.) are correctly forwarded when calling `stress_test_sdk.py` as a subprocess.
|
||||
|
||||
3. **Dark Theme & Visualization Fixes (Assumed in `benchmark_report.py`)**:
|
||||
* (Describes changes assumed to be made in the separate reporting script).
|
||||
|
||||
4. **Clickable Links (`run_benchmark.py`)**:
|
||||
* Added logic to find the latest HTML report and PNG chart in the `benchmark_reports` directory after `benchmark_report.py` runs.
|
||||
* Used `pathlib` to generate correct `file://` URLs for terminal output.
|
||||
|
||||
5. **Documentation Improvements (`USAGE.md`)**:
|
||||
* Rewrote sections to explain `arun_many`, dispatchers, and `--max-sessions`.
|
||||
* Updated parameter tables for all scripts (`stress_test_sdk.py`, `run_benchmark.py`).
|
||||
* Clarified the difference between batch and streaming modes and their effect on logging.
|
||||
* Updated examples to use correct arguments.
|
||||
|
||||
**Files Modified:**
|
||||
- `stress_test_sdk.py`: Changed `--workers` to `--max-sessions`, added new arguments, used `arun_many`.

# Progressive Web Crawling with Adaptive Information Foraging
|
||||
|
||||
## Abstract
|
||||
|
||||
This paper presents a novel approach to web crawling that adaptively determines when sufficient information has been gathered to answer a given query. Unlike traditional exhaustive crawling methods, our Progressive Information Sufficiency (PIS) framework uses statistical measures to balance information completeness against crawling efficiency. We introduce a multi-strategy architecture supporting pure statistical, embedding-enhanced, and LLM-assisted approaches, with theoretical guarantees on convergence and practical evaluation methods using synthetic datasets.
|
||||
|
||||
## 1. Introduction
|
||||
|
||||
Traditional web crawling approaches follow predetermined patterns (breadth-first, depth-first) without consideration for information sufficiency. This work addresses the fundamental question: *"When do we have enough information to answer a query and similar queries in its domain?"*
|
||||
|
||||
We formalize this as an optimal stopping problem in information foraging, introducing metrics for coverage, consistency, and saturation that enable crawlers to make intelligent decisions about when to stop crawling and which links to follow.
|
||||
|
||||
## 2. Problem Formulation
|
||||
|
||||
### 2.1 Definitions
|
||||
|
||||
Let:
|
||||
- **K** = {d₁, d₂, ..., dₙ} be the current knowledge base (crawled documents)
|
||||
- **Q** be the user query
|
||||
- **L** = {l₁, l₂, ..., lₘ} be available links with preview metadata
|
||||
- **θ** be the confidence threshold for information sufficiency
|
||||
|
||||
### 2.2 Objectives
|
||||
|
||||
1. **Minimize** |K| (number of crawled pages)
|
||||
2. **Maximize** P(answers(Q) | K) (probability of answering Q given K)
|
||||
3. **Ensure** coverage of Q's domain (similar queries)
|
||||
|
||||
## 3. Mathematical Framework
|
||||
|
||||
### 3.1 Information Sufficiency Metric
|
||||
|
||||
We define Information Sufficiency as:
|
||||
|
||||
```
|
||||
IS(K, Q) = min(Coverage(K, Q), Consistency(K, Q), 1 - Redundancy(K)) × DomainCoverage(K, Q)
|
||||
```
|
||||
|
||||
### 3.2 Coverage Score
|
||||
|
||||
Coverage measures how well current knowledge covers query terms and related concepts:
|
||||
|
||||
```
|
||||
Coverage(K, Q) = Σ(t ∈ Q) log(df(t, K) + 1) × idf(t) / |Q|
|
||||
```
|
||||
|
||||
Where:
|
||||
- df(t, K) = document frequency of term t in knowledge base K
|
||||
- idf(t) = inverse document frequency weight
|
||||
|
||||
### 3.3 Consistency Score
|
||||
|
||||
Consistency measures information coherence across documents:
|
||||
|
||||
```
|
||||
Consistency(K, Q) = 1 - Var(answers from random subsets of K)
|
||||
```
|
||||
|
||||
This captures the principle that sufficient knowledge should provide stable answers regardless of document subset.
|
||||
|
||||
### 3.4 Saturation Score
|
||||
|
||||
Saturation detects diminishing returns:
|
||||
|
||||
```
|
||||
Saturation(K) = 1 - (ΔInfo(Kₙ) / ΔInfo(K₁))
|
||||
```
|
||||
|
||||
Where ΔInfo represents marginal information gain from the nth crawl.
|
||||
|
||||
### 3.5 Link Value Prediction
|
||||
|
||||
Expected information gain from uncrawled links:
|
||||
|
||||
```
|
||||
ExpectedGain(l) = Relevance(l, Q) × Novelty(l, K) × Authority(l)
|
||||
```
|
||||
|
||||
Components:
|
||||
- **Relevance**: BM25(preview_text, Q)
|
||||
- **Novelty**: 1 - max_similarity(preview, K)
|
||||
- **Authority**: f(url_structure, domain_metrics)
|
||||
|
||||
## 4. Algorithmic Approach
|
||||
|
||||
### 4.1 Progressive Crawling Algorithm
|
||||
|
||||
```
|
||||
Algorithm: ProgressiveCrawl(start_url, query, θ)
|
||||
K ← ∅
|
||||
crawled ← {start_url}
|
||||
pending ← extract_links(crawl(start_url))
|
||||
|
||||
while IS(K, Q) < θ and |crawled| < max_pages:
|
||||
candidates ← rank_by_expected_gain(pending, Q, K)
|
||||
if max(ExpectedGain(candidates)) < min_gain:
|
||||
break // Diminishing returns
|
||||
|
||||
to_crawl ← top_k(candidates)
|
||||
new_docs ← parallel_crawl(to_crawl)
|
||||
K ← K ∪ new_docs
|
||||
crawled ← crawled ∪ to_crawl
|
||||
pending ← extract_new_links(new_docs) - crawled
|
||||
|
||||
return K
|
||||
```
|
||||
|
||||
### 4.2 Stopping Criteria
|
||||
|
||||
Crawling terminates when:
|
||||
1. IS(K, Q) ≥ θ (sufficient information)
|
||||
2. d(IS)/d(crawls) < ε (plateau reached)
|
||||
3. |crawled| ≥ max_pages (resource limit)
|
||||
4. max(ExpectedGain) < min_gain (no promising links)
|
||||
|
||||
## 5. Multi-Strategy Architecture
|
||||
|
||||
### 5.1 Strategy Pattern Design
|
||||
|
||||
```
|
||||
AbstractStrategy
|
||||
├── StatisticalStrategy (no LLM, no embeddings)
|
||||
├── EmbeddingStrategy (with semantic similarity)
|
||||
└── LLMStrategy (with language model assistance)
|
||||
```
|
||||
|
||||
### 5.2 Statistical Strategy
|
||||
|
||||
Pure statistical approach using:
|
||||
- BM25 for relevance scoring
|
||||
- Term frequency analysis for coverage
|
||||
- Graph structure for authority
|
||||
- No external models required
|
||||
|
||||
**Advantages**: Fast, no API costs, works offline
|
||||
**Best for**: Technical documentation, specific terminology
|
||||
|
||||
### 5.3 Embedding Strategy (Implemented)
|
||||
|
||||
Semantic understanding through embeddings:
|
||||
- Query expansion into semantic variations
|
||||
- Coverage mapping in embedding space
|
||||
- Gap-driven link selection
|
||||
- Validation-based stopping criteria
|
||||
|
||||
**Mathematical Framework**:
|
||||
```
|
||||
Coverage(K, Q) = mean(max_similarity(q, K) for q in Q_expanded)
|
||||
Gap(q) = 1 - max_similarity(q, K)
|
||||
LinkScore(l) = Σ(Gap(q) × relevance(l, q)) × (1 - redundancy(l, K))
|
||||
```
|
||||
|
||||
**Key Parameters**:
|
||||
- `embedding_k_exp`: Exponential decay factor for distance-to-score mapping
|
||||
- `embedding_coverage_radius`: Distance threshold for query coverage
|
||||
- `embedding_min_confidence_threshold`: Minimum relevance threshold
|
||||
|
||||
**Advantages**: Semantic understanding, handles ambiguity, detects irrelevance
|
||||
**Best for**: Research queries, conceptual topics, diverse content
|
||||
|
||||
### 5.4 Progressive Enhancement Path
|
||||
|
||||
1. **Level 0**: Statistical only (implemented)
|
||||
2. **Level 1**: + Embeddings for semantic similarity (implemented)
|
||||
3. **Level 2**: + LLM for query understanding (future)
|
||||
|
||||
## 6. Evaluation Methodology
|
||||
|
||||
### 6.1 Synthetic Dataset Generation
|
||||
|
||||
Using LLM to create evaluation data:
|
||||
|
||||
```python
|
||||
def generate_synthetic_dataset(domain_url):
|
||||
# 1. Fully crawl domain
|
||||
full_knowledge = exhaustive_crawl(domain_url)
|
||||
|
||||
# 2. Generate answerable queries
|
||||
queries = llm_generate_queries(full_knowledge)
|
||||
|
||||
# 3. Create query variations
|
||||
for q in queries:
|
||||
variations = generate_variations(q) # synonyms, sub/super queries
|
||||
|
||||
return queries, variations, full_knowledge
|
||||
```
|
||||
|
||||
### 6.2 Evaluation Metrics
|
||||
|
||||
1. **Efficiency**: Information gained / Pages crawled
|
||||
2. **Completeness**: Answerable queries / Total queries
|
||||
3. **Redundancy**: 1 - (Unique information / Total information)
|
||||
4. **Convergence Rate**: Pages to 95% completeness
|
||||
|
||||
### 6.3 Ablation Studies
|
||||
|
||||
- Impact of each score component (coverage, consistency, saturation)
|
||||
- Sensitivity to threshold parameters
|
||||
- Performance across different domain types
|
||||
|
||||
## 7. Theoretical Properties
|
||||
|
||||
### 7.1 Convergence Guarantee
|
||||
|
||||
**Theorem**: For finite websites, ProgressiveCrawl converges to IS(K, Q) ≥ θ or exhausts all reachable pages.
|
||||
|
||||
**Proof sketch**: IS(K, Q) is monotonically non-decreasing with each crawl, bounded above by 1.
|
||||
|
||||
### 7.2 Optimality
|
||||
|
||||
Under certain assumptions about link preview accuracy:
|
||||
- Expected crawls ≤ 2 × optimal_crawls
|
||||
- Approximation ratio improves with preview quality
|
||||
|
||||
## 8. Implementation Design
|
||||
|
||||
### 8.1 Core Components
|
||||
|
||||
1. **CrawlState**: Maintains crawl history and metrics
|
||||
2. **AdaptiveConfig**: Configuration parameters
|
||||
3. **CrawlStrategy**: Pluggable strategy interface
|
||||
4. **AdaptiveCrawler**: Main orchestrator
|
||||
|
||||
### 8.2 Integration with Crawl4AI
|
||||
|
||||
- Wraps existing AsyncWebCrawler
|
||||
- Leverages link preview functionality
|
||||
- Maintains backward compatibility
|
||||
|
||||
### 8.3 Persistence
|
||||
|
||||
Knowledge base serialization for:
|
||||
- Resumable crawls
|
||||
- Knowledge sharing
|
||||
- Offline analysis
|
||||
|
||||
## 9. Future Directions
|
||||
|
||||
### 9.1 Advanced Scoring
|
||||
|
||||
- Temporal information value
|
||||
- Multi-query optimization
|
||||
- Active learning from user feedback
|
||||
|
||||
### 9.2 Distributed Crawling
|
||||
|
||||
- Collaborative knowledge building
|
||||
- Federated information sufficiency
|
||||
|
||||
### 9.3 Domain Adaptation
|
||||
|
||||
- Transfer learning across domains
|
||||
- Meta-learning for threshold selection
|
||||
|
||||
## 10. Conclusion
|
||||
|
||||
Progressive crawling with adaptive information foraging provides a principled approach to efficient web information extraction. By combining coverage, consistency, and saturation metrics, we can determine information sufficiency without ground truth labels. The multi-strategy architecture allows graceful enhancement from pure statistical to LLM-assisted approaches based on requirements and resources.

<summary>🤓 <strong>My Personal Story</strong></summary>
|
||||
|
||||
My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
|
||||
|
||||
Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
|
||||
|
||||
I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
|
||||
|
||||
Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.

|
||||
## Installation 🛠️
|
||||
|
||||
Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.
|
||||
|
||||
<details>
|
||||
<summary>🐍 <strong>Using pip</strong></summary>
|
||||
|
||||
Choose the installation option that best fits your needs:
|
||||
|
||||
### Basic Installation
|
||||
|
||||
For basic web crawling and scraping tasks:
|
||||
|
||||
```bash
|
||||
pip install crawl4ai
|
||||
crawl4ai-setup # Setup the browser
|
||||
```
|
||||
|
||||
By default, this will install the asynchronous version of Crawl4AI, using Playwright for web crawling.
|
||||
|
||||
👉 **Note**: When you install Crawl4AI, the `crawl4ai-setup` should automatically install and set up Playwright. However, if you encounter any Playwright-related errors, you can manually install it using one of these methods:
|
||||
|
||||
1. Through the command line:
|
||||
|
||||
```bash
|
||||
playwright install
|
||||
```
|
||||
|
||||
2. If the above doesn't work, try this more specific command:
|
||||
|
||||
```bash
|
||||
python -m playwright install chromium
|
||||
```
|
||||
|
||||
This second method has proven to be more reliable in some cases.
|
||||
|
||||
---
|
||||
|
||||
### Installation with Synchronous Version
|
||||
|
||||
The sync version is deprecated and will be removed in future versions. If you need the synchronous version using Selenium:
|
||||
|
||||
```bash
|
||||
pip install crawl4ai[sync]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Development Installation
|
||||
|
||||
For contributors who plan to modify the source code:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/unclecode/crawl4ai.git
|
||||
cd crawl4ai
|
||||
pip install -e . # Basic installation in editable mode
|
||||
```
|
||||
|
||||
Install optional features:
|
||||
|
||||
```bash
|
||||
pip install -e ".[torch]" # With PyTorch features
|
||||
pip install -e ".[transformer]" # With Transformer features
|
||||
pip install -e ".[cosine]" # With cosine similarity features
|
||||
pip install -e ".[sync]" # With synchronous crawling (Selenium)
|
||||
pip install -e ".[all]" # Install all optional features
|
||||
```

|
||||
|
||||
Run a quick test (works for both Docker options):
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
# Submit a crawl job
|
||||
response = requests.post(
|
||||
"http://localhost:11235/crawl",
|
||||
json={"urls": ["https://example.com"], "priority": 10}
|
||||
)
|
||||
if response.status_code == 200:
|
||||
print("Crawl job submitted successfully.")
|
||||
|
||||
if "results" in response.json():
|
||||
results = response.json()["results"]
|
||||
print("Crawl job completed. Results:")
|
||||
for result in results:
|
||||
print(result)
|
||||
else:
|
||||
task_id = response.json()["task_id"]
|
||||
print(f"Crawl job submitted. Task ID:: {task_id}")
|
||||
result = requests.get(f"http://localhost:11235/task/{task_id}")
|
||||
```

## ✨ Recent Updates
|
||||
|
||||
### Version 0.7.0 Release Highlights - The Adaptive Intelligence Update
|
||||
|
||||
- **🧠 Adaptive Crawling**: Your crawler now learns and adapts to website patterns automatically:
|
||||
```python
|
||||
config = AdaptiveConfig(
|
||||
confidence_threshold=0.7, # Min confidence to stop crawling
|
||||
max_depth=5, # Maximum crawl depth
|
||||
max_pages=20, # Maximum number of pages to crawl
|
||||
strategy="statistical"
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
adaptive_crawler = AdaptiveCrawler(crawler, config)
|
||||
state = await adaptive_crawler.digest(
|
||||
start_url="https://news.example.com",
|
||||
query="latest news content"
|
||||
)
|
||||
# Crawler learns patterns and improves extraction over time
|
||||
```
|
||||
|
||||
- **🌊 Virtual Scroll Support**: Complete content extraction from infinite scroll pages:
|
||||
```python
|
||||
scroll_config = VirtualScrollConfig(
|
||||
container_selector="[data-testid='feed']",
|
||||
scroll_count=20,
|
||||
scroll_by="container_height",
|
||||
wait_after_scroll=1.0
|
||||
)
|
||||
|
||||
result = await crawler.arun(url, config=CrawlerRunConfig(
|
||||
virtual_scroll_config=scroll_config
|
||||
))
|
||||
```
|
||||
|
||||
- **🔗 Intelligent Link Analysis**: 3-layer scoring system for smart link prioritization:
|
||||
```python
|
||||
link_config = LinkPreviewConfig(
|
||||
query="machine learning tutorials",
|
||||
score_threshold=0.3,
|
||||
concurrent_requests=10
|
||||
)
|
||||
|
||||
result = await crawler.arun(url, config=CrawlerRunConfig(
|
||||
link_preview_config=link_config,
|
||||
score_links=True
|
||||
))
|
||||
# Links ranked by relevance and quality
|
||||
```
|
||||
|
||||
- **🎣 Async URL Seeder**: Discover thousands of URLs in seconds:
|
||||
```python
|
||||
seeder = AsyncUrlSeeder(SeedingConfig(
|
||||
source="sitemap+cc",
|
||||
pattern="*/blog/*",
|
||||
query="python tutorials",
|
||||
score_threshold=0.4
|
||||
))
|
||||
|
||||
urls = await seeder.discover("https://example.com")
|
||||
```
|
||||
|
||||
- **⚡ Performance Boost**: Up to 3x faster with optimized resource handling and memory efficiency

|
||||
|
||||
## Version Numbering in Crawl4AI
|
||||
|
||||
Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.
|
||||
|
||||
### Version Numbers Explained
|
||||
|
||||
Our version numbers follow this pattern: `MAJOR.MINOR.PATCH` (e.g., 0.4.3)
|
||||
|
||||
#### Pre-release Versions
|
||||
We use different suffixes to indicate development stages:
|
||||
|
||||
- `dev` (0.4.3dev1): Development versions, unstable
|
||||
- `a` (0.4.3a1): Alpha releases, experimental features
|
||||
- `b` (0.4.3b1): Beta releases, feature complete but needs testing
|
||||
- `rc` (0.4.3): Release candidates, potential final version
|
||||
|
||||
#### Installation
|
||||
- Regular installation (stable version):
|
||||
```bash
|
||||
pip install -U crawl4ai
|
||||
```
|
||||
|
||||
- Install pre-release versions:
|
||||
```bash
|
||||
pip install crawl4ai --pre
|
||||
```
|
||||
|
||||
- Install specific version:
|
||||
```bash
|
||||
pip install crawl4ai==0.4.3b1
|
||||
```
|
||||
|
||||
#### Why Pre-releases?
|
||||
We use pre-releases to:
|
||||
- Test new features in real-world scenarios
|
||||
- Gather feedback before final releases
|
||||
- Ensure stability for production users
|
||||
- Allow early adopters to try new features
|
||||
|
||||
For production environments, we recommend using the stable version. For testing new features, you can opt-in to pre-releases using the `--pre` flag.

<summary>🤓 <strong>My Personal Story</strong></summary>
|
||||
|
||||
My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
|
||||
I grew up on an Amstrad, thanks to my dad, and never stopped building. In grad school I specialized in NLP and built crawlers for research. That’s where I learned how much extraction matters.
|
||||
|
||||
Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
|
||||
In 2023, I needed web-to-Markdown. The “open source” option wanted an account, API token, and $16, and still under-delivered. I went turbo anger mode, built Crawl4AI in days, and it went viral. Now it’s the most-starred crawler on GitHub.
|
||||
|
||||
I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
|
||||
|
||||
Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.
|
||||
I made it open source for **availability**, anyone can use it without a gate. Now I’m building the platform for **affordability**, anyone can run serious crawls without breaking the bank. If that resonates, join in, send feedback, or just crawl something amazing.

GENERATE_SCRIPT_PROMPT = r"""You are a world-class browser automation specialist. Your sole purpose is to convert a natural language objective and a snippet of HTML into the most **efficient, robust, and simple** script possible to prepare a web page for data extraction.
|
||||
|
||||
Your scripts run **before the crawl** to handle dynamic content, user interactions, and other obstacles. You are a master of two tools: raw **JavaScript** and the high-level **Crawl4ai Script (c4a)**.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Your Core Philosophy: "Efficiency, Robustness, Simplicity"
|
||||
|
||||
This is your mantra. Every line of code you write must adhere to it.
|
||||
|
||||
1. **Efficiency (Shortest Path):** Generate the absolute minimum number of steps to achieve the goal. Do not include redundant actions. If a `CLICK` on one button achieves the goal, don't also scroll and wait unnecessarily.
|
||||
2. **Robustness (Will Not Break):** Prioritize selectors and methods that are resistant to cosmetic site changes. `data-*` attributes are gold. Dynamic, auto-generated class names (`.class-a8B_x3`) are poison. Always prefer waiting for a state change (`WAIT \`#results\``) over a blind delay (`WAIT 5`).
|
||||
3. **Simplicity (Right Tool for the Job):** Use the simplest tool that works. Prefer a direct `c4a` command over `EVAL` with JavaScript. Only use `EVAL` when the task is impossible with standard commands (e.g., accessing Shadow DOM, complex array filtering).
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Output Mode Selection Logic
|
||||
|
||||
Your choice of output mode is a critical strategic decision.
|
||||
|
||||
* **Use `crawl4ai_script` for:**
|
||||
* Standard, sequential browser actions: login forms, clicking "next page," simple "load more" buttons, accepting cookie banners.
|
||||
* When the user's goal maps clearly to the available `c4a` commands.
|
||||
* When you need to define reusable macros with `PROC`.
|
||||
|
||||
* **Use `javascript` for:**
|
||||
* Complex DOM manipulation that has no `c4a` equivalent (e.g., transforming data, complex filtering).
|
||||
* Interacting with web components inside **Shadow DOM** or **iFrames**.
|
||||
* Implementing sophisticated logic like custom scrolling patterns or handling non-standard events.
|
||||
* When the goal is a fine-grained DOM tweak, not a full user journey.
|
||||
|
||||
**If the user specifies a mode, you MUST respect it.** If not, you must choose the mode that best embodies your core philosophy.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Available Crawl4ai Commands
|
||||
|
||||
| Command | Arguments / Notes |
|
||||
|------------------------|--------------------------------------------------------------|
|
||||
| GO `<url>` | Navigate to absolute URL |
|
||||
| RELOAD | Hard refresh |
|
||||
| BACK / FORWARD | Browser history nav |
|
||||
| WAIT `<seconds>` | **Avoid!** Passive delay. Use only as a last resort. |
|
||||
| WAIT \`<css>\` `<t>` | **Preferred wait.** Poll selector until found, timeout in seconds. |
|
||||
| WAIT "<text>" `<t>` | Poll page text until found, timeout in seconds. |
|
||||
| CLICK \`<css>\` | Single click on element |
|
||||
| CLICK `<x>` `<y>` | Viewport click |
|
||||
| DOUBLE_CLICK … | Two rapid clicks |
|
||||
| RIGHT_CLICK … | Context-menu click |
|
||||
| MOVE `<x>` `<y>` | Mouse move |
|
||||
| DRAG `<x1>` `<y1>` `<x2>` `<y2>` | Click-drag gesture |
|
||||
| SCROLL UP|DOWN|LEFT|RIGHT `[px]` | Viewport scroll |
|
||||
| TYPE "<text>" | Type into focused element |
|
||||
| CLEAR \`<css>\` | Empty input |
|
||||
| SET \`<css>\` "<val>" | Set element value and dispatch events |
|
||||
| PRESS `<Key>` | Keydown + keyup |
|
||||
| KEY_DOWN `<Key>` / KEY_UP `<Key>` | Separate key events |
|
||||
| EVAL \`<js>\` | **Your fallback.** Run JS when no direct command exists. |
|
||||
| SETVAR $name = <val> | Store constant for reuse |
|
||||
| PROC name … ENDPROC | Define macro |
|
||||
| IF / ELSE / REPEAT | Flow control |
|
||||
| USE "<file.c4a>" | Include another script, avoid circular includes |
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Strategic Principles & Anti-Patterns
|
||||
|
||||
These are your commandments. Do not deviate.
|
||||
|
||||
1. **Selector Quality is Paramount:**
|
||||
* **GOOD:** `[data-testid="submit-button"]`, `#main-content`, `[aria-label="Close dialog"]`
|
||||
* **BAD:** `div > span:nth-child(3)`, `.button-gR3xY_s`, `//div[contains(@class, 'button')]`
|
||||
|
||||
2. **Wait for State, Not for Time:**
|
||||
* **DO:** `CLICK \`#load-more\`` followed by `WAIT \`div.new-item\` 10`. This waits for the *result* of the action.
|
||||
* **DON'T:** `CLICK \`#load-more\`` followed by `WAIT 5`. This is a guess and it will fail.
|
||||
|
||||
3. **Target the Action, Not the Artifact:** If you need to reveal content, click the button that reveals it. Don't try to manually change CSS `display` properties, as this can break the page's internal state.
|
||||
|
||||
4. **DOM-Awareness is Non-Negotiable:**
|
||||
* **Shadow DOM:** `c4a` commands CANNOT pierce the Shadow DOM. If you see a `#shadow-root (open)` in the HTML, you MUST use `EVAL` and `element.shadowRoot.querySelector(...)`.
|
||||
* **iFrames:** Likewise, you MUST use `EVAL` and `iframe.contentDocument.querySelector(...)` to interact with elements inside an iframe.
|
||||
|
||||
5. **Be Idempotent:** Your script must be harmless if run multiple times. Use `IF EXISTS` to check for states before acting (e.g., don't try to log in if already logged in).
|
||||
|
||||
6. **Forbidden Techniques:** Never use `document.write()`. It is destructive. Avoid overly complex JS in `EVAL` that could be simplified into a few `c4a` commands.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## From Vague Goals to Robust Scripts: Your Duty to Infer and Ensure Reliability
|
||||
|
||||
This is your most important responsibility. Users are not automation experts. They will provide incomplete or vague instructions. Your job is to be the expert—to infer their true goal and build a script that is reliable by default. You must add the "invisible scaffolding" of checks and waits to ensure the page is stable and ready for the crawler. **A vague user prompt must still result in a robust, complete script.**
|
||||
|
||||
Study these examples. No matter which query is given, your output must be the single, robust solution.
|
||||
|
||||
### 1. Scenario: Basic Search Query
|
||||
|
||||
* **High Detail Query:** "Find the search box and search button. Wait for the search box to be visible, click it, clear it, type 'r2d2', click the search button, and then wait for the search results to appear."
|
||||
* **Medium Detail Query:** "Find the search box and search for 'r2d2', click the search button until you get a list of items."
|
||||
* **Low Detail Query:** "Search for r2d2."
|
||||
|
||||
**THE CORRECT, ROBUST OUTPUT (for all three queries):**
|
||||
```
|
||||
WAIT `input[type="search"]` 10
|
||||
SET `input[type="search"]` "r2d2"
|
||||
CLICK `button[aria-label="Search"]`
|
||||
WAIT `div.search-results-container` 15
|
||||
```
|
||||
**Rationale:** You correctly infer the need to `WAIT` for the input first. You use the more efficient `SET` command. Most importantly, you **infer the crucial final step**: waiting for a results container to appear, confirming the search action was successful.
|
||||
|
||||
### 2. Scenario: Clicking a "Load More" Button
|
||||
|
||||
* **High Detail Query:** "Click the button with the text 'Load More'. Afterward, wait for a new item with the class '.product-tile' to show up on the page."
|
||||
* **Medium Detail Query:** "Click the load more button to see more products."
|
||||
* **Low Detail Query:** "Load more items."
|
||||
|
||||
**THE CORRECT, ROBUST OUTPUT:**
|
||||
```
|
||||
IF EXISTS `button.load-more` THEN
|
||||
CLICK `button.load-more`
|
||||
WAIT `div.new-item-indicator` 8
|
||||
ENDIF
|
||||
```
|
||||
**Rationale:** You wrap the action in `IF EXISTS` to prevent errors if the button is not present (e.g., on the last page). You correctly infer the need to wait for the *consequence* of the click—a new item appearing—rather than a blind `WAIT 2`.
|
||||
|
||||
### 3. Scenario: Applying a Filter from a Dropdown
|
||||
|
||||
* **High Detail Query:** "First, click the dropdown with id 'color-filter'. Then, from the open menu, click the option that says 'Blue'. Finally, wait for the product grid to update."
|
||||
* **Medium Detail Query:** "Filter the products by the color Blue."
|
||||
* **Low Detail Query:** "Show blue products."
|
||||
|
||||
**THE CORRECT, ROBUST OUTPUT:**
|
||||
```
|
||||
CLICK `#color-filter`
|
||||
WAIT `[data-value="blue"]` 3
|
||||
CLICK `[data-value="blue"]`
|
||||
WAIT `#product-grid[data-status="updated"]` 10
|
||||
```
|
||||
**Rationale:** You infer the need for two waits: one for the menu options to appear after the first click, and a second for the main content to update after the filter is applied. This prevents race conditions.
|
||||
|
||||
### 4. Scenario: User Authentication (Login)
|
||||
|
||||
* **High Detail Query:** "Fill username with 'USER_EMAIL', fill password with 'USER_PASS', click login, and wait for the dashboard to appear."
|
||||
* **Medium Detail Query:** "Log in as USER_EMAIL with password USER_PASS."
|
||||
* **Low Detail Query:** "Log in."
|
||||
|
||||
**THE CORRECT, ROBUST OUTPUT:**
|
||||
```
|
||||
IF EXISTS `[data-testid="logout-button"]` THEN
|
||||
EVAL `console.log("Already logged in.")`
|
||||
ELSE
|
||||
WAIT `input[name="username"]` 10
|
||||
SET `input[name="username"]` "USER_EMAIL"
|
||||
SET `input[name="password"]` "USER_PASS"
|
||||
CLICK `button[type="submit"]`
|
||||
WAIT `[data-testid="user-dashboard"]` 15
|
||||
ENDIF
|
||||
```
|
||||
**Rationale:** You build an **idempotent** script. You first check if the user is *already* logged in. If not, you proceed with the login and then, critically, `WAIT` for a post-login element to confirm success. You use placeholders when credentials are not provided in low-detail queries.
|
||||
|
||||
### 5. Scenario: Dismissing an Interstitial Modal
|
||||
|
||||
* **High Detail Query:** "Check if a popup with id '#promo-modal' exists. If it does, click the close button inside it with class '.close-x'."
|
||||
* **Medium Detail Query:** "Close the promotional popup."
|
||||
* **Low Detail Query:** "Get rid of the popup."
|
||||
|
||||
**THE CORRECT, ROBUST OUTPUT:**
|
||||
```
|
||||
IF EXISTS `div#promo-modal` THEN
|
||||
CLICK `div#promo-modal button.close-x`
|
||||
ENDIF
|
||||
```
|
||||
**Rationale:** You correctly identify this as a conditional action. The script must not fail if the popup doesn't appear. The `IF EXISTS` block is the perfect, robust way to handle this optional interaction.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Advanced Scenarios & Master-Level Examples
|
||||
|
||||
Study these solutions. Understand the *why* behind each choice.
|
||||
|
||||
### Scenario: Interacting with a Web Component (Shadow DOM)
|
||||
**Goal:** Click a button inside a custom element `<user-card>`.
|
||||
**HTML Snippet:** `<user-card><#shadow-root (open)><button>Details</button></#shadow-root></user-card>`
|
||||
**Correct Mode:** `javascript` (or `c4a` with `EVAL`)
|
||||
**Rationale:** Standard selectors can't cross the shadow boundary. JavaScript is mandatory.
|
||||
|
||||
```javascript
|
||||
// Solution in pure JS mode
|
||||
const card = document.querySelector('user-card');
|
||||
if (card && card.shadowRoot) {
|
||||
const button = card.shadowRoot.querySelector('button');
|
||||
if (button) button.click();
|
||||
}
|
||||
```
|
||||
```
|
||||
# Solution in c4a mode (using EVAL as the weapon of choice)
|
||||
EVAL `
|
||||
const card = document.querySelector('user-card');
|
||||
if (card && card.shadowRoot) {
|
||||
const button = card.shadowRoot.querySelector('button');
|
||||
if (button) button.click();
|
||||
}
|
||||
`
|
||||
```
|
||||
|
||||
### Scenario: Handling a Cookie Banner
|
||||
**Goal:** Accept the cookies to dismiss the modal.
|
||||
**HTML Snippet:** `<div id="cookie-consent-modal"><button id="accept-cookies">Accept All</button></div>`
|
||||
**Correct Mode:** `crawl4ai_script`
|
||||
**Rationale:** A simple, direct action. `c4a` is cleaner and more declarative.
|
||||
|
||||
```
|
||||
# The most efficient solution
|
||||
IF EXISTS `#cookie-consent-modal` THEN
|
||||
CLICK `#accept-cookies`
|
||||
WAIT `div.content-loaded` 5
|
||||
ENDIF
|
||||
```
|
||||
|
||||
### Scenario: Infinite Scroll Page
|
||||
**Goal:** Scroll down 5 times to load more content.
|
||||
**HTML Snippet:** `(A page with a long body and no "load more" button)`
|
||||
**Correct Mode:** `crawl4ai_script`
|
||||
**Rationale:** `REPEAT` is designed for exactly this. It's more readable than a JS loop for this simple task.
|
||||
|
||||
```
|
||||
REPEAT (
|
||||
SCROLL DOWN 1000,
|
||||
5
|
||||
)
|
||||
WAIT 2
|
||||
```
|
||||
|
||||
### Scenario: Hover-to-Reveal Menu
|
||||
**Goal:** Hover over "Products" to open the menu, then click "Laptops".
|
||||
**HTML Snippet:** `<a href="/products" id="products-menu">Products</a> <div class="menu-dropdown"><a href="/laptops">Laptops</a></div>`
|
||||
**Correct Mode:** `crawl4ai_script` (with `EVAL`)
|
||||
**Rationale:** `c4a` has no `HOVER` command. `EVAL` is the perfect tool to dispatch the `mouseover` event.
|
||||
|
||||
```
|
||||
EVAL `document.querySelector('#products-menu').dispatchEvent(new MouseEvent('mouseover', { bubbles: true }))`
|
||||
WAIT `div.menu-dropdown a[href="/laptops"]` 3
|
||||
CLICK `div.menu-dropdown a[href="/laptops"]`
|
||||
```
|
||||
|
||||
### Scenario: Login Form
|
||||
**Goal:** Fill and submit a login form.
|
||||
**HTML Snippet:** `<form><input name="email"><input name="password" type="password"><button type="submit"></button></form>`
|
||||
**Correct Mode:** `crawl4ai_script`
|
||||
**Rationale:** This is the canonical use case for `c4a`. The commands map 1:1 to the user journey.
|
||||
|
||||
```
|
||||
WAIT `form` 10
|
||||
SET `input[name="email"]` "USER_EMAIL"
|
||||
SET `input[name="password"]` "USER_PASS"
|
||||
CLICK `button[type="submit"]`
|
||||
WAIT `[data-testid="user-dashboard"]` 12
|
||||
```
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Final Output Mandate
|
||||
|
||||
1. **CODE ONLY.** Your entire response must be the script body.
|
||||
2. **NO CHAT.** Do not say "Here is the script" or "This should work."
|
||||
3. **NO MARKDOWN.** Do not wrap your code in ` ``` ` fences.
|
||||
4. **NO COMMENTS.** Do not add comments to the final code output.
|
||||
5. **SYNTACTICALLY PERFECT.** The script must be immediately executable.
|
||||
6. **UTF-8, STANDARD QUOTES.** Use `"` for string literals, not `“` or `”`.
|
||||
|
||||
You are an engine of automation. Now, receive the user's request and produce the optimal script."""

GENERATE_JS_SCRIPT_PROMPT = """# The World-Class JavaScript Automation Scripter
|
||||
|
||||
You are a world-class browser automation specialist. Your sole purpose is to convert a natural language objective and a snippet of HTML into the most **efficient, robust, and simple** pure JavaScript script possible to prepare a web page for data extraction.
|
||||
|
||||
Your scripts will be executed directly in the browser (e.g., via Playwright's `page.evaluate()`) to handle dynamic content, user interactions, and other obstacles before the page is crawled. You are a master of browser-native JavaScript APIs.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Your Core Philosophy: "Efficiency, Robustness, Simplicity"
|
||||
|
||||
This is your mantra. Every line of JavaScript you write must adhere to it.
|
||||
|
||||
1. **Efficiency (Shortest Path):** Generate the absolute minimum number of steps to achieve the goal. Do not include redundant actions. Your code should be concise and direct.
|
||||
2. **Robustness (Will Not Break):** Prioritize selectors that are resistant to cosmetic site changes. `data-*` attributes are gold. Dynamic, auto-generated class names (`.class-a8B_x3`) are poison. Always prefer waiting for a state change over a blind `setTimeout`.
|
||||
3. **Simplicity (Right Tool for the Job):** Use simple, direct DOM methods (`.querySelector`, `.click()`) whenever possible. Avoid overly complex or fragile logic when a simpler approach exists.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Essential JavaScript Automation Patterns & Toolkit
|
||||
|
||||
All code should be wrapped in an `async` Immediately Invoked Function Expression `(async () => { ... })();` to allow for top-level `await` and to avoid polluting the global scope.
|
||||
|
||||
| Task | Best-Practice JavaScript Implementation |
|
||||
| -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| **Wait for Element** | Create and use a robust `waitForElement` helper function. This is your most important tool. <br> `const waitForElement = (selector, timeout = 10000) => new Promise((resolve, reject) => { const el = document.querySelector(selector); if (el) return resolve(el); const observer = new MutationObserver(() => { const el = document.querySelector(selector); if (el) { observer.disconnect(); resolve(el); } }); observer.observe(document.body, { childList: true, subtree: true }); setTimeout(() => { observer.disconnect(); reject(new Error(`Timeout waiting for ${selector}`)); }, timeout); });` |
|
||||
| **Click Element** | `const el = await waitForElement('selector'); if (el) el.click();` |
|
||||
| **Set Input Value** | `const input = await waitForElement('selector'); if (input) { input.value = 'new value'; input.dispatchEvent(new Event('input', { bubbles: true })); input.dispatchEvent(new Event('change', { bubbles: true })); }` <br> *Crucially, always dispatch `input` and `change` events to trigger framework reactivity.* |
|
||||
| **Check Existence** | `const el = document.querySelector('selector'); if (el) { /* ... it exists */ }` |
|
||||
| **Scroll** | `window.scrollBy(0, window.innerHeight);` |
|
||||
| **Deal with Time** | Use `await new Promise(r => setTimeout(r, 500));` for short, unavoidable pauses after an action. **Avoid long, blind waits.** |
|
||||
|
||||
REMEMBER: Make sure to generate very deterministic css selector. If you refer to a specific button, then be specific, otherwise you may capture elements you do not need, be very specific about the element you want to interact with.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## The Art of High-Specificity Selectors: Your Defense Against Ambiguity
|
||||
|
||||
This is your most critical skill for ensuring robustness. **You must assume the provided HTML is only a small fragment of the entire page.** A selector that looks unique in the fragment could be disastrously generic on the full page. Your primary defense is to **anchor your selectors to the most specific, stable parent element available in the given HTML context.**
|
||||
|
||||
Think of it as creating a "sandbox" for your selectors.
|
||||
|
||||
**Your Guiding Principle:** Start from a unique parent, then find the child.
|
||||
|
||||
### Scenario: Selecting a Submit Button within a Login Form
|
||||
|
||||
**HTML Snippet Provided:**
|
||||
```html
|
||||
<div class="user-auth-module" id="login-widget">
|
||||
<h2>Member Login</h2>
|
||||
<form action="/login">
|
||||
<input name="email" type="email">
|
||||
<input name="password" type="password">
|
||||
<button type="submit">Sign In</button>
|
||||
</form>
|
||||
</div>
|
||||
```
|
||||
|
||||
* **TERRIBLE (High Risk):** `button[type="submit"]`
|
||||
* **Why it's bad:** There could be dozens of other forms on the full page (e.g., a newsletter signup, a search bar in the header). This selector is a shot in the dark.
|
||||
|
||||
* **BETTER (Lower Risk):** `#login-widget button[type="submit"]`
|
||||
* **Why it's better:** It's anchored to a unique ID (`#login-widget`). This dramatically reduces the chance of ambiguity.
|
||||
|
||||
* **EXCELLENT (Minimal Risk):** `div[id="login-widget"] form button[type="submit"]`
|
||||
* **Why it's best:** This is a highly specific, descriptive path. It says, "Find the login widget, then the form inside it, and then the submit button inside *that* form." It is virtually guaranteed to be unique and is resilient to minor layout changes within the form.
|
||||
|
||||
### Scenario: Selecting a "Add to Cart" Button
|
||||
|
||||
**HTML Snippet Provided:**
|
||||
```html
|
||||
<section data-testid="product-details-main">
|
||||
<h1>Awesome T-Shirt</h1>
|
||||
<div class="product-actions">
|
||||
<button class="add-to-cart-btn">Add to Cart</button>
|
||||
</div>
|
||||
</section>
|
||||
```
|
||||
|
||||
* **TERRIBLE (High Risk):** `.add-to-cart-btn`
|
||||
* **Why it's bad:** A "related products" section outside this snippet might also use the same class name.
|
||||
|
||||
* **EXCELLENT (Minimal Risk):** `[data-testid="product-details-main"] .add-to-cart-btn`
|
||||
* **Why it's best:** It uses the stable `data-testid` attribute of the parent section as an anchor. This is the most robust pattern.
|
||||
|
||||
**Your Mandate:** Always examine the provided HTML for a stable, unique parent (like an element with an `id`, a `data-testid`, or a highly specific combination of classes) and use it as the root of your selectors. **NEVER generate a generic, un-anchored selector if a better, more specific parent is available in the context.**
|
||||
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## Strategic Principles & Anti-Patterns
|
||||
|
||||
These are your commandments. Do not deviate.
|
||||
|
||||
1. **Selector Quality is Paramount:**
|
||||
* **GOOD:** `[data-testid="submit-button"]`, `#main-content`, `[aria-label="Close dialog"]`
|
||||
* **BAD:** `div > span:nth-child(3)`, `.button-gR3xY_s`, `//div[contains(@class, 'button')]`
|
||||
|
||||
2. **Wait for State, Not for Time:**
|
||||
* **DO:** `(await waitForElement('#load-more')).click(); await waitForElement('div.new-item');` This waits for the *result* of the action.
|
||||
* **DON'T:** `document.querySelector('#load-more').click(); await new Promise(r => setTimeout(r, 5000));` This is a guess and it will fail.
|
||||
|
||||
3. **Target the Action, Not the Artifact:** If you need to reveal content, click the button that reveals it. Don't try to manually change CSS `display` properties, as this can break the page's internal state.
|
||||
|
||||
4. **DOM-Awareness is Non-Negotiable:**
|
||||
* **Shadow DOM:** You MUST use `element.shadowRoot.querySelector(...)` to access elements inside a `#shadow-root (open)`.
|
||||
* **iFrames:** You MUST use `iframe.contentDocument.querySelector(...)` to interact with elements inside an iframe.
|
||||
|
||||
5. **Be Idempotent:** Your script must be harmless if run multiple times. Use `if (document.querySelector(...))` checks to avoid re-doing actions unnecessarily.
|
||||
|
||||
6. **Forbidden Techniques:** Never use `document.write()`. It is destructive.
|
||||
|
||||
────────────────────────────────────────────────────────
|
||||
## From Vague Goals to Robust Scripts: Your Duty to Infer and Ensure Reliability
|
||||
|
||||
This is your most important responsibility. Users are not automation experts. They will provide incomplete or vague instructions. Your job is to be the expert—to infer their true goal and build a script that is reliable by default. **A vague user prompt must still result in a robust, complete script.**
|
||||
|
||||
Study these examples. No matter which query is given, your output must be the single, robust solution.
|
||||
|
||||
### 1. Scenario: Basic Search Query
|
||||
|
||||
* **High Detail Query:** "Find the search box and search button. Wait for the search box to be visible, click it, clear it, type 'r2d2', click the search button, and then wait for the search results to appear."
|
||||
* **Medium Detail Query:** "Find the search box and search for 'r2d2'."
|
||||
* **Low Detail Query:** "Search for r2d2."
|
||||
|
||||
**THE CORRECT, ROBUST JAVASCRIPT OUTPUT (for all three queries):**
|
||||
```javascript
|
||||
(async () => {
|
||||
const waitForElement = (selector, timeout = 10000) => new Promise((resolve, reject) => { const el = document.querySelector(selector); if (el) return resolve(el); const observer = new MutationObserver(() => { const el = document.querySelector(selector); if (el) { observer.disconnect(); resolve(el); } }); observer.observe(document.body, { childList: true, subtree: true }); setTimeout(() => { observer.disconnect(); reject(new Error(`Timeout waiting for ${selector}`)); }, timeout); });
|
||||
try {
|
||||
const searchInput = await waitForElement('input[type="search"], input[aria-label*="search"]');
|
||||
searchInput.value = 'r2d2';
|
||||
searchInput.dispatchEvent(new Event('input', { bubbles: true }));
|
||||
const searchButton = await waitForElement('button[type="submit"], button[aria-label*="search"]');
|
||||
searchButton.click();
|
||||
await waitForElement('div.search-results-container, #search-results');
|
||||
} catch (e) {
|
||||
console.error('Search script failed:', e.message);
|
||||
}
|
||||
})();
|
||||
```
|
||||
|
||||
### 2. Scenario: Clicking a "Load More" Button
|
||||
|
||||
* **High Detail Query:** "Click the button with the text 'Load More'. Afterward, wait for a new item with the class '.product-tile' to show up."
|
||||
* **Medium Detail Query:** "Click the load more button."
|
||||
* **Low Detail Query:** "Load more items."
|
||||
|
||||
**THE CORRECT, ROBUST JAVASCRIPT OUTPUT:**
|
||||
```javascript
|
||||
(async () => {
|
||||
const loadMoreButton = document.querySelector('button.load-more, [data-testid="load-more"]');
|
||||
if (loadMoreButton) {
|
||||
const initialItemCount = document.querySelectorAll('.product-tile').length;
|
||||
loadMoreButton.click();
|
||||
const waitForNewItem = (timeout = 8000) => new Promise((resolve, reject) => { const t0 = Date.now(); const check = () => { if (document.querySelectorAll('.product-tile').length > initialItemCount) return resolve(); if (Date.now() - t0 > timeout) return reject(new Error('Timeout waiting for new items to load.')); setTimeout(check, 200); }; check(); });
|
||||
await waitForNewItem();
|
||||
}
|
||||
})();
|
||||
```
|
||||
|
||||
### 3. Scenario: User Authentication (Login)
|
||||
|
||||
* **High Detail Query:** "Fill username with 'USER_EMAIL', password with 'USER_PASS', click login, and wait for the dashboard."
|
||||
* **Medium Detail Query:** "Log in as USER_EMAIL."
|
||||
* **Low Detail Query:** "Log in."
|
||||
|
||||
**THE CORRECT, ROBUST JAVASCRIPT OUTPUT:**
|
||||
```javascript
|
||||
(async () => {
|
||||
if (document.querySelector('[data-testid="logout-button"]')) {
|
||||
console.log('Already logged in.');
|
||||
return;
|
||||
}
|
||||
const waitForElement = (selector, timeout = 10000) => new Promise((resolve, reject) => { const el = document.querySelector(selector); if (el) return resolve(el); const observer = new MutationObserver(() => { const el = document.querySelector(selector); if (el) { observer.disconnect(); resolve(el); } }); observer.observe(document.body, { childList: true, subtree: true }); setTimeout(() => { observer.disconnect(); reject(new Error(`Timeout waiting for ${selector}`)); }, timeout); });
|
||||
try {
|
||||
const userInput = await waitForElement('input[name*="user"], input[name*="email"]');
|
||||
userInput.value = 'USER_EMAIL';
|
||||
userInput.dispatchEvent(new Event('input', { bubbles: true }));
|
||||
const passInput = await waitForElement('input[name*="pass"], input[type="password"]');
|
||||
passInput.value = 'USER_PASS';
|
||||
passInput.dispatchEvent(new Event('input', { bubbles: true }));
|
||||
const submitButton = await waitForElement('button[type="submit"]');
|
||||
submitButton.click();
|
||||
await waitForElement('[data-testid="user-dashboard"], #dashboard, .account-page');
|
||||
} catch (e) {
|
||||
console.error('Login script failed:', e.message);
|
||||
}
|
||||
})();
|
||||
```

## Prerequisites
|
||||
|
||||
Before we dive in, make sure you have:
|
||||
- Docker installed and running (version 20.10.0 or higher), including `docker compose` (usually bundled with Docker Desktop).
|
||||
- `git` for cloning the repository.
|
||||
- At least 4GB of RAM available for the container (more recommended for heavy use).
|
||||
- Python 3.10+ (if using the Python SDK).
|
||||
- Node.js 16+ (if using the Node.js examples).
|
||||
|
||||
> 💡 **Pro tip**: Run `docker info` to check your Docker installation and available resources.
|
||||
|
||||
## Installation
|
||||
|
||||
We offer several ways to get the Crawl4AI server running. Docker Compose is the easiest way to manage local builds and runs.
|
||||
|
||||
### Option 1: Using Docker Compose (Recommended)
|
||||
|
||||
Docker Compose simplifies building and running the service, especially for local development and testing across different platforms.
|
||||
|
||||
#### 1. Clone Repository
|
||||
|
||||
```bash
|
||||
git clone https://github.com/unclecode/crawl4ai.git
|
||||
cd crawl4ai
|
||||
```
|
||||
|
||||
#### 2. Environment Setup (API Keys)
|
||||
|
||||
If you plan to use LLMs, copy the example environment file and add your API keys. This file should be in the **project root directory**.
|
||||
|
||||
```bash
|
||||
# Make sure you are in the 'crawl4ai' root directory
|
||||
cp deploy/docker/.llm.env.example .llm.env
|
||||
|
||||
# Now edit .llm.env and add your API keys
|
||||
# Example content:
|
||||
# OPENAI_API_KEY=sk-your-key
|
||||
# ANTHROPIC_API_KEY=your-anthropic-key
|
||||
# ...
|
||||
```
|
||||
> 🔑 **Note**: Keep your API keys secure! Never commit `.llm.env` to version control.
|
||||
|
||||
#### 3. Build and Run with Compose
|
||||
|
||||
The `docker-compose.yml` file in the project root defines services for different scenarios using **profiles**.
|
||||
|
||||
* **Build and Run Locally (AMD64):**
|
||||
```bash
|
||||
# Builds the image locally using Dockerfile and runs it
|
||||
docker compose --profile local-amd64 up --build -d
|
||||
```
|
||||
|
||||
* **Build and Run Locally (ARM64):**
|
||||
```bash
|
||||
# Builds the image locally using Dockerfile and runs it
|
||||
docker compose --profile local-arm64 up --build -d
|
||||
```
|
||||
|
||||
* **Run Pre-built Image from Docker Hub (AMD64):**
|
||||
```bash
|
||||
# Pulls and runs the specified AMD64 image from Docker Hub
|
||||
# (Set VERSION env var for specific tags, e.g., VERSION=0.5.1-d1)
|
||||
docker compose --profile hub-amd64 up -d
|
||||
```
|
||||
|
||||
* **Run Pre-built Image from Docker Hub (ARM64):**
|
||||
```bash
|
||||
# Pulls and runs the specified ARM64 image from Docker Hub
|
||||
docker compose --profile hub-arm64 up -d
|
||||
```
|
||||
|
||||
> The server will be available at `http://localhost:11235`.
|
||||
|
||||
#### 4. Stopping Compose Services
|
||||
|
||||
```bash
|
||||
# Stop the service(s) associated with a profile (e.g., local-amd64)
|
||||
docker compose --profile local-amd64 down
|
||||
```
|
||||
|
||||
### Option 2: Manual Local Build & Run
|
||||
|
||||
If you prefer not to use Docker Compose for local builds.
|
||||
|
||||
#### 1. Clone Repository & Setup Environment
|
||||
|
||||
Follow steps 1 and 2 from the Docker Compose section above (clone repo, `cd crawl4ai`, create `.llm.env` in the root).
|
||||
|
||||
#### 2. Build the Image (Multi-Arch)
|
||||
|
||||
Use `docker buildx` to build the image. This example builds for multiple platforms and loads the image matching your host architecture into the local Docker daemon.
|
||||
|
||||
```bash
|
||||
# Make sure you are in the 'crawl4ai' root directory
|
||||
docker buildx build --platform linux/amd64,linux/arm64 -t crawl4ai-local:latest --load .
|
||||
```
|
||||
|
||||
#### 3. Run the Container
|
||||
|
||||
* **Basic run (no LLM support):**
|
||||
```bash
|
||||
# Replace --platform if your host is ARM64
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--name crawl4ai-standalone \
|
||||
--shm-size=1g \
|
||||
--platform linux/amd64 \
|
||||
crawl4ai-local:latest
|
||||
```
|
||||
|
||||
* **With LLM support:**
|
||||
```bash
|
||||
# Make sure .llm.env is in the current directory (project root)
|
||||
# Replace --platform if your host is ARM64
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--name crawl4ai-standalone \
|
||||
--env-file .llm.env \
|
||||
--shm-size=1g \
|
||||
--platform linux/amd64 \
|
||||
crawl4ai-local:latest
|
||||
```
|
||||
|
||||
> The server will be available at `http://localhost:11235`.
|
||||
|
||||
#### 4. Stopping the Manual Container
|
||||
|
||||
```bash
|
||||
docker stop crawl4ai-standalone && docker rm crawl4ai-standalone
|
||||
```
|
||||
|
||||
### Option 3: Using Pre-built Docker Hub Images
|
||||
|
||||
Pull and run images directly from Docker Hub without building locally.
|
||||
|
||||
#### 1. Pull the Image
|
||||
|
||||
We use a versioning scheme like `LIBRARY_VERSION-dREVISION` (e.g., `0.5.1-d1`). The `latest` tag points to the most recent stable release. Images are built with multi-arch manifests, so Docker usually pulls the correct version for your system automatically.
|
||||
|
||||
```bash
|
||||
# Pull a specific version (recommended for stability)
|
||||
docker pull unclecode/crawl4ai:0.5.1-d1
|
||||
|
||||
# Or pull the latest stable version
|
||||
docker pull unclecode/crawl4ai:latest
|
||||
```
|
||||
|
||||
#### 2. Setup Environment (API Keys)
|
||||
|
||||
If using LLMs, create the `.llm.env` file in a directory of your choice, similar to Step 2 in the Compose section.
|
||||
|
||||
#### 3. Run the Container
|
||||
|
||||
* **Basic run:**
|
||||
```bash
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--name crawl4ai-hub \
|
||||
--shm-size=1g \
|
||||
unclecode/crawl4ai:0.5.1-d1 # Or use :latest
|
||||
```
|
||||
|
||||
* **With LLM support:**
|
||||
```bash
|
||||
# Make sure .llm.env is in the current directory you are running docker from
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--name crawl4ai-hub \
|
||||
--env-file .llm.env \
|
||||
--shm-size=1g \
|
||||
unclecode/crawl4ai:0.5.1-d1 # Or use :latest
|
||||
```
|
||||
|
||||
> The server will be available at `http://localhost:11235`.
|
||||
|
||||
#### 4. Stopping the Hub Container
|
||||
|
||||
```bash
|
||||
docker stop crawl4ai-hub && docker rm crawl4ai-hub
|
||||
```
|
||||
|
||||
#### Docker Hub Versioning Explained
|
||||
|
||||
* **Image Name:** `unclecode/crawl4ai`
|
||||
* **Tag Format:** `LIBRARY_VERSION-dREVISION`
|
||||
* `LIBRARY_VERSION`: The Semantic Version of the core `crawl4ai` Python library included (e.g., `0.5.1`).
|
||||
* `dREVISION`: An incrementing number (starting at `d1`) for Docker build changes made *without* changing the library version (e.g., base image updates, dependency fixes). Resets to `d1` for each new `LIBRARY_VERSION`.
|
||||
* **Example:** `unclecode/crawl4ai:0.5.1-d1`
|
||||
* **`latest` Tag:** Points to the most recent stable `LIBRARY_VERSION-dREVISION`.
|
||||
* **Multi-Arch:** Images support `linux/amd64` and `linux/arm64`. Docker automatically selects the correct architecture.

|
||||
|
||||
## Dockerfile Parameters
|
||||
|
||||
You can customize the image build process using build arguments (`--build-arg`). These are typically used via `docker buildx build` or within the `docker-compose.yml` file.
|
||||
|
||||
```bash
|
||||
# Example: Build with 'all' features using buildx
|
||||
docker buildx build \
|
||||
--platform linux/amd64,linux/arm64 \
|
||||
--build-arg INSTALL_TYPE=all \
|
||||
-t yourname/crawl4ai-all:latest \
|
||||
--load \
|
||||
. # Build from root context
|
||||
```
|
||||
|
||||
### Build Arguments Explained
|
||||
|
||||
| Argument | Description | Default | Options |
|
||||
| :----------- | :--------------------------------------- | :-------- | :--------------------------------- |
|
||||
| INSTALL_TYPE | Feature set | `default` | `default`, `all`, `torch`, `transformer` |
|
||||
| ENABLE_GPU | GPU support (CUDA for AMD64) | `false` | `true`, `false` |
|
||||
| APP_HOME | Install path inside container (advanced) | `/app` | any valid path |
|
||||
| USE_LOCAL | Install library from local source | `true` | `true`, `false` |
|
||||
| GITHUB_REPO | Git repo to clone if USE_LOCAL=false | *(see Dockerfile)* | any git URL |
|
||||
| GITHUB_BRANCH| Git branch to clone if USE_LOCAL=false | `main` | any branch name |
|
||||
|
||||
*(Note: PYTHON_VERSION is fixed by the `FROM` instruction in the Dockerfile)*
|
||||
|
||||
### Build Best Practices
|
||||
|
||||
1. **Choose the Right Install Type**
|
||||
* `default`: Basic installation, smallest image size. Suitable for most standard web scraping and markdown generation.
|
||||
* `all`: Full features including `torch` and `transformers` for advanced extraction strategies (e.g., CosineStrategy, certain LLM filters). Significantly larger image. Ensure you need these extras.
|
||||
2. **Platform Considerations**
|
||||
* Use `buildx` for building multi-architecture images, especially for pushing to registries.
|
||||
* Use `docker compose` profiles (`local-amd64`, `local-arm64`) for easy platform-specific local builds.
|
||||
3. **Performance Optimization**
|
||||
* The image automatically includes platform-specific optimizations (OpenMP for AMD64, OpenBLAS for ARM64).

Communicate with the running Docker server via its REST API (defaulting to `http://localhost:11235`). You can use the Python SDK or make direct HTTP requests.
|
||||
|
||||
### Python SDK
|
||||
|
||||
Install the SDK: `pip install crawl4ai`
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai.docker_client import Crawl4aiDockerClient
|
||||
from crawl4ai import BrowserConfig, CrawlerRunConfig, CacheMode # Assuming you have crawl4ai installed
|
||||
|
||||
async def main():
|
||||
# Point to the correct server port
|
||||
async with Crawl4aiDockerClient(base_url="http://localhost:11235", verbose=True) as client:
|
||||
# If JWT is enabled on the server, authenticate first:
|
||||
# await client.authenticate("user@example.com") # See Server Configuration section
|
||||
|
||||
# Example Non-streaming crawl
|
||||
print("--- Running Non-Streaming Crawl ---")
|
||||
results = await client.crawl(
|
||||
["https://httpbin.org/html"],
|
||||
browser_config=BrowserConfig(headless=True), # Use library classes for config aid
|
||||
crawler_config=CrawlerRunConfig(cache_mode=CacheMode.BYPASS)
|
||||
)
|
||||
if results: # client.crawl returns None on failure
|
||||
print(f"Non-streaming results success: {results.success}")
|
||||
if results.success:
|
||||
for result in results: # Iterate through the CrawlResultContainer
|
||||
print(f"URL: {result.url}, Success: {result.success}")
|
||||
else:
|
||||
print("Non-streaming crawl failed.")
|
||||
|
||||
|
||||
# Example Streaming crawl
|
||||
print("\n--- Running Streaming Crawl ---")
|
||||
stream_config = CrawlerRunConfig(stream=True, cache_mode=CacheMode.BYPASS)
|
||||
try:
|
||||
async for result in await client.crawl( # client.crawl returns an async generator for streaming
|
||||
["https://httpbin.org/html", "https://httpbin.org/links/5/0"],
|
||||
browser_config=BrowserConfig(headless=True),
|
||||
crawler_config=stream_config
|
||||
):
|
||||
print(f"Streamed result: URL: {result.url}, Success: {result.success}")
|
||||
except Exception as e:
|
||||
print(f"Streaming crawl failed: {e}")
|
||||
|
||||
|
||||
# Example Get schema
|
||||
print("\n--- Getting Schema ---")
|
||||
schema = await client.get_schema()
|
||||
print(f"Schema received: {bool(schema)}") # Print whether schema was received
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
*(SDK parameters like timeout, verify_ssl etc. remain the same)*
|
||||
|
||||
### Second Approach: Direct API Calls
|
||||
|
||||
Crucially, when sending configurations directly via JSON, they **must** follow the `{"type": "ClassName", "params": {...}}` structure for any non-primitive value (like config objects or strategies). Dictionaries must be wrapped as `{"type": "dict", "value": {...}}`.
|
||||
|
||||
*(Keep the detailed explanation of Configuration Structure, Basic Pattern, Simple vs Complex, Strategy Pattern, Complex Nested Example, Quick Grammar Overview, Important Rules, Pro Tip)*
|
||||
|
||||
#### More Examples *(Ensure Schema example uses type/value wrapper)*
|
||||
|
||||
**Advanced Crawler Configuration**
|
||||
*(Keep example, ensure cache_mode uses valid enum value like "bypass")*
|
||||
|
||||
**Extraction Strategy**
|
||||
```json
|
||||
{
|
||||
"crawler_config": {
|
||||
"type": "CrawlerRunConfig",
|
||||
"params": {
|
||||
"extraction_strategy": {
|
||||
"type": "JsonCssExtractionStrategy",
|
||||
"params": {
|
||||
"schema": {
|
||||
"type": "dict",
|
||||
"value": {
|
||||
"baseSelector": "article.post",
|
||||
"fields": [
|
||||
{"name": "title", "selector": "h1", "type": "text"},
|
||||
{"name": "content", "selector": ".content", "type": "html"}
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**LLM Extraction Strategy** *(Keep example, ensure schema uses type/value wrapper)*
|
||||
*(Keep Deep Crawler Example)*
|
||||
|
||||
### REST API Examples
|
||||
|
||||
Update URLs to use port `11235`.
|
||||
|
||||
#### Simple Crawl
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
# Configuration objects converted to the required JSON structure
|
||||
browser_config_payload = {
|
||||
"type": "BrowserConfig",
|
||||
"params": {"headless": True}
|
||||
}
|
||||
crawler_config_payload = {
|
||||
"type": "CrawlerRunConfig",
|
||||
"params": {"stream": False, "cache_mode": "bypass"} # Use string value of enum
|
||||
}
|
||||
|
||||
crawl_payload = {
|
||||
"urls": ["https://httpbin.org/html"],
|
||||
"browser_config": browser_config_payload,
|
||||
"crawler_config": crawler_config_payload
|
||||
}
|
||||
response = requests.post(
|
||||
"http://localhost:11235/crawl", # Updated port
|
||||
# headers={"Authorization": f"Bearer {token}"}, # If JWT is enabled
|
||||
json=crawl_payload
|
||||
)
|
||||
print(f"Status Code: {response.status_code}")
|
||||
if response.ok:
|
||||
print(response.json())
|
||||
else:
|
||||
print(f"Error: {response.text}")
|
||||
|
||||
```
|
||||
|
||||
#### Streaming Results
|
||||
|
||||
```python
|
||||
import json
|
||||
import httpx # Use httpx for async streaming example
|
||||
|
||||
async def test_stream_crawl(token: str = None): # Made token optional
|
||||
"""Test the /crawl/stream endpoint with multiple URLs."""
|
||||
url = "http://localhost:11235/crawl/stream" # Updated port
|
||||
payload = {
|
||||
"urls": [
|
||||
"https://httpbin.org/html",
|
||||
"https://httpbin.org/links/5/0",
|
||||
],
|
||||
"browser_config": {
|
||||
"type": "BrowserConfig",
|
||||
"params": {"headless": True, "viewport": {"type": "dict", "value": {"width": 1200, "height": 800}}} # Viewport needs type:dict
|
||||
},
|
||||
"crawler_config": {
|
||||
"type": "CrawlerRunConfig",
|
||||
"params": {"stream": True, "cache_mode": "bypass"}
|
||||
}
|
||||
}
|
||||
|
||||
headers = {}
|
||||
# if token:
|
||||
# headers = {"Authorization": f"Bearer {token}"} # If JWT is enabled
|
||||
|
||||
try:
|
||||
async with httpx.AsyncClient() as client:
|
||||
async with client.stream("POST", url, json=payload, headers=headers, timeout=120.0) as response:
|
||||
print(f"Status: {response.status_code} (Expected: 200)")
|
||||
response.raise_for_status() # Raise exception for bad status codes
|
||||
|
||||
# Read streaming response line-by-line (NDJSON)
|
||||
async for line in response.aiter_lines():
|
||||
if line:
|
||||
try:
|
||||
data = json.loads(line)
|
||||
# Check for completion marker
|
||||
if data.get("status") == "completed":
|
||||
print("Stream completed.")
|
||||
break
|
||||
print(f"Streamed Result: {json.dumps(data, indent=2)}")
|
||||
except json.JSONDecodeError:
|
||||
print(f"Warning: Could not decode JSON line: {line}")
|
||||
|
||||
except httpx.HTTPStatusError as e:
|
||||
print(f"HTTP error occurred: {e.response.status_code} - {e.response.text}")
|
||||
except Exception as e:
|
||||
print(f"Error in streaming crawl test: {str(e)}")
|
||||
|
||||
# To run this example:
|

# import asyncio
|
||||
# asyncio.run(test_stream_crawl())
|
||||
```

## Metrics & Monitoring
|
||||
|
||||
Keep an eye on your crawler with these endpoints:
|
||||
|
||||
- `/health` - Quick health check
|
||||
- `/metrics` - Detailed Prometheus metrics
|
||||
- `/schema` - Full API schema
|
||||
|
||||
Example health check:
|
||||
```bash
|
||||
curl http://localhost:11235/health
|
||||
```
|
||||

|
||||
|
||||
## Server Configuration
|
||||
|
||||
The server's behavior can be customized through the `config.yml` file.
|
||||
|
||||
### Understanding config.yml
|
||||
|
||||
The configuration file is loaded from `/app/config.yml` inside the container. By default, the file from `deploy/docker/config.yml` in the repository is copied there during the build.
|
||||
|
||||
Here's a detailed breakdown of the configuration options (using defaults from `deploy/docker/config.yml`):
|
||||
|
||||
```yaml
|
||||
# Application Configuration
|
||||
app:
|
||||
title: "Crawl4AI API"
|
||||
version: "1.0.0" # Consider setting this to match library version, e.g., "0.5.1"
|
||||
host: "0.0.0.0"
|
||||
port: 8020 # NOTE: This port is used ONLY when running server.py directly. Gunicorn overrides this (see supervisord.conf).
|
||||
reload: False # Default set to False - suitable for production
|
||||
timeout_keep_alive: 300
|
||||
|
||||
# Default LLM Configuration
|
||||
llm:
|
||||
provider: "openai/gpt-4o-mini"
|
||||
api_key_env: "OPENAI_API_KEY"
|
||||
# api_key: sk-... # If you pass the API key directly then api_key_env will be ignored
|
||||
|
||||
# Redis Configuration (Used by internal Redis server managed by supervisord)
|
||||
redis:
|
||||
host: "localhost"
|
||||
port: 6379
|
||||
db: 0
|
||||
password: ""
|
||||
# ... other redis options ...
|
||||
|
||||
# Rate Limiting Configuration
|
||||
rate_limiting:
|
||||
enabled: True
|
||||
default_limit: "1000/minute"
|
||||
trusted_proxies: []
|
||||
storage_uri: "memory://" # Use "redis://localhost:6379" if you need persistent/shared limits
|
||||
|
||||
# Security Configuration
|
||||
security:
|
||||
enabled: false # Master toggle for security features
|
||||
jwt_enabled: false # Enable JWT authentication (requires security.enabled=true)
|
||||
https_redirect: false # Force HTTPS (requires security.enabled=true)
|
||||
trusted_hosts: ["*"] # Allowed hosts (use specific domains in production)
|
||||
headers: # Security headers (applied if security.enabled=true)
|
||||
x_content_type_options: "nosniff"
|
||||
x_frame_options: "DENY"
|
||||
content_security_policy: "default-src 'self'"
|
||||
strict_transport_security: "max-age=63072000; includeSubDomains"
|
||||
|
||||
# Crawler Configuration
|
||||
crawler:
|
||||
memory_threshold_percent: 95.0
|
||||
rate_limiter:
|
||||
base_delay: [1.0, 2.0] # Min/max delay between requests in seconds for dispatcher
|
||||
timeouts:
|
||||
stream_init: 30.0 # Timeout for stream initialization
|
||||
batch_process: 300.0 # Timeout for non-streaming /crawl processing
|
||||
|
||||
# Logging Configuration
|
||||
logging:
|
||||
level: "INFO"
|
||||
format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
|
||||
|
||||
# Observability Configuration
|
||||
observability:
|
||||
prometheus:
|
||||
enabled: True
|
||||
endpoint: "/metrics"
|
||||
health_check:
|
||||
endpoint: "/health"
|
||||
```
|
||||
|
||||
*(JWT Authentication section remains the same, just note the default port is now 11235 for requests)*
|
||||
|
||||
*(Configuration Tips and Best Practices remain the same)*
|
||||
|
||||
### Customizing Your Configuration
|
||||
|
||||
You can override the default `config.yml`.
|
||||
|
||||
#### Method 1: Modify Before Build
|
||||
|
||||
1. Edit the `deploy/docker/config.yml` file in your local repository clone.
|
||||
2. Build the image using `docker buildx` or `docker compose --profile local-... up --build`. The modified file will be copied into the image.
|
||||
|
||||
#### Method 2: Runtime Mount (Recommended for Custom Deploys)
|
||||
|
||||
1. Create your custom configuration file, e.g., `my-custom-config.yml` locally. Ensure it contains all necessary sections.
|
||||
2. Mount it when running the container:
|
||||
|
||||
* **Using `docker run`:**
|
||||
```bash
|
||||
# Assumes my-custom-config.yml is in the current directory
|
||||
docker run -d -p 11235:11235 \
|
||||
--name crawl4ai-custom-config \
|
||||
--env-file .llm.env \
|
||||
--shm-size=1g \
|
||||
-v $(pwd)/my-custom-config.yml:/app/config.yml \
|
||||
unclecode/crawl4ai:latest # Or your specific tag
|
||||
```
|
||||
|
||||
* **Using `docker-compose.yml`:** Add a `volumes` section to the service definition:
|
||||
```yaml
|
||||
services:
|
||||
crawl4ai-hub-amd64: # Or your chosen service
|
||||
image: unclecode/crawl4ai:latest
|
||||
profiles: ["hub-amd64"]
|
||||
<<: *base-config
|
||||
volumes:
|
||||
# Mount local custom config over the default one in the container
|
||||
- ./my-custom-config.yml:/app/config.yml
|
||||
# Keep the shared memory volume from base-config
|
||||
- /dev/shm:/dev/shm
|
||||
```
|
||||
*(Note: Ensure `my-custom-config.yml` is in the same directory as `docker-compose.yml`)*
|
||||
|
||||
> 💡 When mounting, your custom file *completely replaces* the default one. Ensure it's a valid and complete configuration.
|
||||
|
||||
### Configuration Recommendations
|
||||
|
||||
1. **Security First** 🔒
|
||||
- Always enable security in production
|
||||
- Use specific trusted_hosts instead of wildcards
|
||||
- Set up proper rate limiting to protect your server
|
||||
- Consider your environment before enabling HTTPS redirect
|
||||
|
||||
2. **Resource Management** 💻
|
||||
- Adjust memory_threshold_percent based on available RAM
|
||||
- Set timeouts according to your content size and network conditions
|
||||
- Use Redis for rate limiting in multi-container setups
|
||||
|
||||
3. **Monitoring** 📊
|
||||
- Enable Prometheus if you need metrics
|
||||
- Set DEBUG logging in development, INFO in production
|
||||
- Regular health check monitoring is crucial
|
||||
|
||||
4. **Performance Tuning** ⚡
|
||||
- Start with conservative rate limiter delays
|
||||
- Increase batch_process timeout for large content
|
||||
- Adjust stream_init timeout based on initial response times
|
||||

# Crawl4AI Prospect‑Wizard – step‑by‑step guide
|
||||
|
||||
[](https://colab.research.google.com/drive/10nRCwmfxPjVrRUHyJsYlX7BH5bvPoGpx?usp=sharing)
|
||||
|
||||
A three‑stage demo that goes from **LinkedIn scraping** ➜ **LLM reasoning** ➜ **graph visualisation**.
|
||||
|
||||
**Try it in Google Colab!** Click the badge above to run this demo in a cloud environment with zero setup required.
|
||||
|
||||
```
|
||||
prospect‑wizard/
|
||||
├─ c4ai_discover.py # Stage 1 – scrape companies + people
|
||||
├─ c4ai_insights.py # Stage 2 – embeddings, org‑charts, scores
|
||||
├─ graph_view_template.html # Stage 3 – graph viewer (static HTML)
|
||||
└─ data/ # output lands here (*.jsonl / *.json)
|
||||
```
|
||||

|
||||
|
||||
## 1 Install & boot a LinkedIn profile (one‑time)
|
||||
|
||||
### 1.1 Install dependencies
|
||||
```bash
|
||||
pip install crawl4ai litellm sentence-transformers pandas rich
|
||||
```
|
||||
|
||||
### 1.2 Create / warm a LinkedIn browser profile
|
||||
```bash
|
||||
crwl profiles
|
||||
```
|
||||
1. The interactive shell shows **New profile** – hit **enter**.
|
||||
2. Choose a name, e.g. `profile_linkedin_uc`.
|
||||
3. A Chromium window opens – log in to LinkedIn, solve whatever CAPTCHA, then close.
|
||||
|
||||
> Remember the **profile name**. All future runs take `--profile-name <your_name>`.
|
||||
|
||||
---
|
||||
|
||||
## 2 Discovery – scrape companies & people
|
||||
|
||||
```bash
|
||||
python c4ai_discover.py full \
|
||||
--query "health insurance management" \
|
||||
--geo 102713980 \ # Malaysia geoUrn
|
||||
--title-filters "" \ # or "Product,Engineering"
|
||||
--max-companies 10 \ # default set small for workshops
|
||||
--max-people 20 \ # \^ same
|
||||
--profile-name profile_linkedin_uc \
|
||||
--outdir ./data \
|
||||
--concurrency 2 \
|
||||
--log-level debug
|
||||
```
|
||||
**Outputs** in `./data/`:
|
||||
* `companies.jsonl` – one JSON per company
|
||||
* `people.jsonl` – one JSON per employee
|
||||
|
||||
🛠️ **Dry‑run:** `C4AI_DEMO_DEBUG=1 python c4ai_discover.py full --query coffee` uses bundled HTML snippets, no network.

||||

|
||||
|
||||
## 3 Insights – embeddings, org‑charts, decision makers
|
||||
|
||||
```bash
|
||||
python c4ai_insights.py \
|
||||
--in ./data \
|
||||
--out ./data \
|
||||
--embed-model all-MiniLM-L6-v2 \
|
||||
--llm-provider gemini/gemini-2.0-flash \
|
||||
--llm-api-key "" \
|
||||
--top-k 10 \
|
||||
--max-llm-tokens 8024 \
|
||||
--llm-temperature 1.0 \
|
||||
--workers 4
|
||||
```
|
||||
Emits next to the Stage‑1 files:
|
||||
* `company_graph.json` – inter‑company similarity graph
|
||||
* `org_chart_<handle>.json` – one per company
|
||||
* `decision_makers.csv` – hand‑picked ‘who to pitch’ list
|
||||
|
||||
Flags reference (straight from `build_arg_parser()`):
|
||||
| Flag | Default | Purpose |
|
||||
|------|---------|---------|
|
||||
| `--in` | `.` | Stage‑1 output dir |
|
||||
| `--out` | `.` | Destination dir |
|
||||
| `--embed_model` | `all-MiniLM-L6-v2` | Sentence‑Transformer model |
|
||||
| `--top_k` | `10` | Neighbours per company in graph |
|
||||
| `--openai_model` | `gpt-4.1` | LLM for scoring decision makers |
|
||||
| `--max_llm_tokens` | `8024` | Token budget per LLM call |
|
||||
| `--llm_temperature` | `1.0` | Creativity knob |
|
||||
| `--stub` | off | Skip OpenAI and fabricate tiny charts |
|
||||
| `--workers` | `4` | Parallel LLM workers |
|
||||
|
||||
---
|
||||
|
||||
## 4 Visualise – interactive graph
|
||||
|
||||
After Stage 2 completes, simply open the HTML viewer from the project root:
|
||||
```bash
|
||||
open graph_view_template.html # or Live Server / Python -http
|
||||
```
|
||||
The page fetches `data/company_graph.json` and the `org_chart_*.json` files automatically; keep the `data/` folder beside the HTML file.
|
||||
|
||||
* Left pane → list of companies (clans).
|
||||
* Click a node to load its org‑chart on the right.
|
||||
* Chat drawer lets you ask follow‑up questions; context is pulled from `people.jsonl`.
|
||||

|
||||
|
||||
## 5 Common snags
|
||||
|
||||
| Symptom | Fix |
|
||||
|---------|-----|
|
||||
| Infinite CAPTCHA | Use a residential proxy: `--proxy http://user:pass@ip:port` |
|
||||
| 429 Too Many Requests | Lower `--concurrency`, rotate profile, add delay |
|
||||
| Blank graph | Check JSON paths, clear `localStorage` in browser |
|
||||
|
||||
---
|
||||
|
||||
### TL;DR
|
||||
`crwl profiles` → `c4ai_discover.py` → `c4ai_insights.py` → open `graph_view_template.html`.
|
||||
Live long and `import crawl4ai`.

c4ai-discover — Stage‑1 Discovery CLI
|
||||
|
||||
Scrapes LinkedIn company search + their people pages and dumps two newline‑delimited
|
||||
JSON files: companies.jsonl and people.jsonl.
|
||||
|
||||
Key design rules
|
||||
----------------
|
||||
* No BeautifulSoup — Crawl4AI only for network + HTML fetch.
|
||||
* JsonCssExtractionStrategy for structured scraping; schema auto‑generated once
|
||||
from sample HTML provided by user and then cached under ./schemas/.
|
||||
* Defaults are embedded so the file runs inside VS Code debugger without CLI args.
|
||||
* If executed as a console script (argv > 1), CLI flags win.
|
||||
* Lightweight deps: argparse + Crawl4AI stack.

The main div parent contains these li element is "div.search-results-container" you can use this.

The <ul> parent has "role" equal to "list". Using these two should be enough to target the <li> elements.

IMPORTANT: Remember there might be multiple <a> tags that start with https://www.linkedin.com/company/[NAME],

so in case you refer to them for different fields, make sure to be more specific. One has the image, and one

has the person's name.
|

|

IMPORTANT: Be very smart in selecting the correct and unique way to address the element. You should ensure

your selector points to a single element and is unique to the place that contains the information.

# 🚀 Crawl4AI v0.7.0: The Adaptive Intelligence Update
|
||||
|
||||
*January 28, 2025 • 10 min read*
|
||||
|
||||
---
|
||||
|
||||
Today I'm releasing Crawl4AI v0.7.0—the Adaptive Intelligence Update. This release introduces fundamental improvements in how Crawl4AI handles modern web complexity through adaptive learning, intelligent content discovery, and advanced extraction capabilities.
|
||||
|
||||
## 🎯 What's New at a Glance
|
||||
|
||||
- **Adaptive Crawling**: Your crawler now learns and adapts to website patterns
|
||||
- **Virtual Scroll Support**: Complete content extraction from infinite scroll pages
|
||||
- **Link Preview with Intelligent Scoring**: Intelligent link analysis and prioritization
|
||||
- **Async URL Seeder**: Discover thousands of URLs in seconds with intelligent filtering
|
||||
- **Performance Optimizations**: Significant speed and memory improvements
|
||||
|
||||
## 🧠 Adaptive Crawling: Intelligence Through Pattern Learning
|
||||
|
||||
**The Problem:** Websites change. Class names shift. IDs disappear. Your carefully crafted selectors break at 3 AM, and you wake up to empty datasets and angry stakeholders.
|
||||
|
||||
**My Solution:** I implemented an adaptive learning system that observes patterns, builds confidence scores, and adjusts extraction strategies on the fly. It's like having a junior developer who gets better at their job with every page they scrape.
|
||||
|
||||
### Technical Deep-Dive
|
||||
|
||||
The Adaptive Crawler maintains a persistent state for each domain, tracking:
|
||||
- Pattern success rates
|
||||
- Selector stability over time
|
||||
- Content structure variations
|
||||
- Extraction confidence scores
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, AdaptiveCrawler, AdaptiveConfig
|
||||
import asyncio
|
||||
|
||||
async def main():
|
||||
|
||||
# Configure adaptive crawler
|
||||
config = AdaptiveConfig(
|
||||
strategy="statistical", # or "embedding" for semantic understanding
|
||||
max_pages=10,
|
||||
confidence_threshold=0.7, # Stop at 70% confidence
|
||||
top_k_links=3, # Follow top 3 links per page
|
||||
min_gain_threshold=0.05 # Need 5% information gain to continue
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(verbose=False) as crawler:
|
||||
adaptive = AdaptiveCrawler(crawler, config)
|
||||
|
||||
print("Starting adaptive crawl about Python decorators...")
|
||||
result = await adaptive.digest(
|
||||
start_url="https://docs.python.org/3/glossary.html",
|
||||
query="python decorators functions wrapping"
|
||||
)
|
||||
|
||||
print(f"\n✅ Crawling Complete!")
|
||||
print(f"• Confidence Level: {adaptive.confidence:.0%}")
|
||||
print(f"• Pages Crawled: {len(result.crawled_urls)}")
|
||||
print(f"• Knowledge Base: {len(adaptive.state.knowledge_base)} documents")
|
||||
|
||||
# Get most relevant content
|
||||
relevant = adaptive.get_relevant_content(top_k=3)
|
||||
print(f"\nMost Relevant Pages:")
|
||||
for i, page in enumerate(relevant, 1):
|
||||
print(f"{i}. {page['url']} (relevance: {page['score']:.2%})")
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **News Aggregation**: Maintain 95%+ extraction accuracy even as news sites update their templates
|
||||
- **E-commerce Monitoring**: Track product changes across hundreds of stores without constant maintenance
|
||||
- **Research Data Collection**: Build robust academic datasets that survive website redesigns
|
||||
- **Reduced Maintenance**: Cut selector update time by 80% for frequently-changing sites
|
||||
|
||||
## 🌊 Virtual Scroll: Complete Content Capture
|
||||
|
||||
**The Problem:** Modern web apps only render what's visible. Scroll down, new content appears, old content vanishes into the void. Traditional crawlers capture that first viewport and miss 90% of the content. It's like reading only the first page of every book.
|
||||
|
||||
**My Solution:** I built Virtual Scroll support that mimics human browsing behavior, capturing content as it loads and preserving it before the browser's garbage collector strikes.
|
||||
|
||||
### Implementation Details
|
||||
|
||||
```python
|
||||
from crawl4ai import VirtualScrollConfig
|
||||
|
||||
# For social media feeds (Twitter/X style)
|
||||
twitter_config = VirtualScrollConfig(
|
||||
container_selector="[data-testid='primaryColumn']",
|
||||
scroll_count=20, # Number of scrolls
|
||||
scroll_by="container_height", # Smart scrolling by container size
|
||||
wait_after_scroll=1.0 # Let content load
|
||||
)
|
||||
|
||||
# For e-commerce product grids (Instagram style)
|
||||
grid_config = VirtualScrollConfig(
|
||||
container_selector="main .product-grid",
|
||||
scroll_count=30,
|
||||
scroll_by=800, # Fixed pixel scrolling
|
||||
wait_after_scroll=1.5 # Images need time
|
||||
)
|
||||
|
||||
# For news feeds with lazy loading
|
||||
news_config = VirtualScrollConfig(
|
||||
container_selector=".article-feed",
|
||||
scroll_count=50,
|
||||
scroll_by="page_height", # Viewport-based scrolling
|
||||
wait_after_scroll=0.5 # Wait for content to load
|
||||
)
|
||||
|
||||
# Use it in your crawl
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
"https://twitter.com/trending",
|
||||
config=CrawlerRunConfig(
|
||||
virtual_scroll_config=twitter_config,
|
||||
# Combine with other features
|
||||
extraction_strategy=JsonCssExtractionStrategy({
|
||||
"tweets": {
|
||||
"selector": "[data-testid='tweet']",
|
||||
"fields": {
|
||||
"text": {"selector": "[data-testid='tweetText']", "type": "text"},
|
||||
"likes": {"selector": "[data-testid='like']", "type": "text"}
|
||||
}
|
||||
}
|
||||
})
|
||||
)
|
||||
)
|
||||
|
||||
print(f"Captured {len(result.extracted_content['tweets'])} tweets")
|
||||
```
|
||||
|
||||
**Key Capabilities:**
|
||||
- **DOM Recycling Awareness**: Detects and handles virtual DOM element recycling
|
||||
- **Smart Scroll Physics**: Three modes - container height, page height, or fixed pixels
|
||||
- **Content Preservation**: Captures content before it's destroyed
|
||||
- **Intelligent Stopping**: Stops when no new content appears
|
||||
- **Memory Efficient**: Streams content instead of holding everything in memory
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Social Media Analysis**: Capture entire Twitter threads with hundreds of replies, not just top 10
|
||||
- **E-commerce Scraping**: Extract 500+ products from infinite scroll catalogs vs. 20-50 with traditional methods
|
||||
- **News Aggregation**: Get all articles from modern news sites, not just above-the-fold content
|
||||
- **Research Applications**: Complete data extraction from academic databases using virtual pagination
|
||||
|
||||
## 🔗 Link Preview: Intelligent Link Analysis and Scoring
|
||||
|
||||
**The Problem:** You crawl a page and get 200 links. Which ones matter? Which lead to the content you actually want? Traditional crawlers force you to follow everything or build complex filters.
|
||||
|
||||
**My Solution:** I implemented a three-layer scoring system that analyzes links like a human would—considering their position, context, and relevance to your goals.
|
||||
|
||||
### Intelligent Link Analysis and Scoring
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import CrawlerRunConfig, CacheMode, AsyncWebCrawler
|
||||
from crawl4ai.adaptive_crawler import LinkPreviewConfig
|
||||
|
||||
async def main():
|
||||
# Configure intelligent link analysis
|
||||
link_config = LinkPreviewConfig(
|
||||
include_internal=True,
|
||||
include_external=False,
|
||||
max_links=10,
|
||||
concurrency=5,
|
||||
query="python tutorial", # For contextual scoring
|
||||
score_threshold=0.3,
|
||||
verbose=True
|
||||
)
|
||||
# Use in your crawl
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
"https://www.geeksforgeeks.org/",
|
||||
config=CrawlerRunConfig(
|
||||
link_preview_config=link_config,
|
||||
score_links=True, # Enable intrinsic scoring
|
||||
cache_mode=CacheMode.BYPASS
|
||||
)
|
||||
)
|
||||
|
||||
# Access scored and sorted links
|
||||
if result.success and result.links:
|
||||
for link in result.links.get("internal", []):
|
||||
text = link.get('text', 'No text')[:40]
|
||||
print(
|
||||
text,
|
||||
f"{link.get('intrinsic_score', 0):.1f}/10" if link.get('intrinsic_score') is not None else "0.0/10",
|
||||
f"{link.get('contextual_score', 0):.2f}/1" if link.get('contextual_score') is not None else "0.00/1",
|
||||
f"{link.get('total_score', 0):.3f}" if link.get('total_score') is not None else "0.000"
|
||||
)
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
**Scoring Components:**
|
||||
|
||||
1. **Intrinsic Score**: Based on link quality indicators
|
||||
- Position on page (navigation, content, footer)
|
||||
- Link attributes (rel, title, class names)
|
||||
- Anchor text quality and length
|
||||
- URL structure and depth
|
||||
|
||||
2. **Contextual Score**: Relevance to your query using BM25 algorithm
|
||||
- Keyword matching in link text and title
|
||||
- Meta description analysis
|
||||
- Content preview scoring
|
||||
|
||||
3. **Total Score**: Combined score for final ranking
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Research Efficiency**: Find relevant papers 10x faster by following only high-score links
|
||||
- **Competitive Analysis**: Automatically identify important pages on competitor sites
|
||||
- **Content Discovery**: Build topic-focused crawlers that stay on track
|
||||
- **SEO Audits**: Identify and prioritize high-value internal linking opportunities
|
||||
|
||||
## 🎣 Async URL Seeder: Automated URL Discovery at Scale
|
||||
|
||||
**The Problem:** You want to crawl an entire domain but only have the homepage. Or worse, you want specific content types across thousands of pages. Manual URL discovery? That's a job for machines, not humans.
|
||||
|
||||
**My Solution:** I built Async URL Seeder—a turbocharged URL discovery engine that combines multiple sources with intelligent filtering and relevance scoring.
|
||||
|
||||
### Technical Architecture
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncUrlSeeder, SeedingConfig
|
||||
|
||||
async def main():
|
||||
async with AsyncUrlSeeder() as seeder:
|
||||
# Discover Python tutorial URLs
|
||||
config = SeedingConfig(
|
||||
source="sitemap", # Use sitemap
|
||||
pattern="*python*", # URL pattern filter
|
||||
extract_head=True, # Get metadata
|
||||
query="python tutorial", # For relevance scoring
|
||||
scoring_method="bm25",
|
||||
score_threshold=0.2,
|
||||
max_urls=10
|
||||
)
|
||||
|
||||
print("Discovering Python async tutorial URLs...")
|
||||
urls = await seeder.urls("https://www.geeksforgeeks.org/", config)
|
||||
|
||||
print(f"\n✅ Found {len(urls)} relevant URLs:")
|
||||
for i, url_info in enumerate(urls[:5], 1):
|
||||
print(f"\n{i}. {url_info['url']}")
|
||||
if url_info.get('relevance_score'):
|
||||
print(f" Relevance: {url_info['relevance_score']:.3f}")
|
||||
if url_info.get('head_data', {}).get('title'):
|
||||
print(f" Title: {url_info['head_data']['title'][:60]}...")
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
**Discovery Methods:**
|
||||
- **Sitemap Mining**: Parses robots.txt and all linked sitemaps
|
||||
- **Common Crawl**: Queries the Common Crawl index for historical URLs
|
||||
- **Intelligent Crawling**: Follows links with smart depth control
|
||||
- **Pattern Analysis**: Learns URL structures and generates variations
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Migration Projects**: Discover 10,000+ URLs from legacy sites in under 60 seconds
|
||||
- **Market Research**: Map entire competitor ecosystems automatically
|
||||
- **Academic Research**: Build comprehensive datasets without manual URL collection
|
||||
- **SEO Audits**: Find every indexable page with content scoring
|
||||
- **Content Archival**: Ensure no content is left behind during site migrations
|
||||
|
||||
## ⚡ Performance Optimizations
|
||||
|
||||
This release includes significant performance improvements through optimized resource handling, better concurrency management, and reduced memory footprint.
|
||||
|
||||
### What We Optimized
|
||||
|
||||
```python
|
||||
# Optimized crawling with v0.7.0 improvements
|
||||
results = []
|
||||
for url in urls:
|
||||
result = await crawler.arun(
|
||||
url,
|
||||
config=CrawlerRunConfig(
|
||||
# Performance optimizations
|
||||
wait_until="domcontentloaded", # Faster than networkidle
|
||||
cache_mode=CacheMode.ENABLED # Enable caching
|
||||
)
|
||||
)
|
||||
results.append(result)
|
||||
```
|
||||
|
||||
**Performance Gains:**
|
||||
- **Startup Time**: 70% faster browser initialization
|
||||
- **Page Loading**: 40% reduction with smart resource blocking
|
||||
- **Extraction**: 3x faster with compiled CSS selectors
|
||||
- **Memory Usage**: 60% reduction with streaming processing
|
||||
- **Concurrent Crawls**: Handle 5x more parallel requests
|
||||
|
||||
|
||||
## 🔧 Important Changes
|
||||
|
||||
### Breaking Changes
|
||||
- `link_extractor` renamed to `link_preview` (better reflects functionality)
|
||||
- Minimum Python version now 3.9
|
||||
- `CrawlerConfig` split into `CrawlerRunConfig` and `BrowserConfig`
|
||||
|
||||
### Migration Guide
|
||||
```python
|
||||
# Old (v0.6.x)
|
||||
from crawl4ai import CrawlerConfig
|
||||
config = CrawlerConfig(timeout=30000)
|
||||
|
||||
# New (v0.7.0)
|
||||
from crawl4ai import CrawlerRunConfig, BrowserConfig
|
||||
browser_config = BrowserConfig(timeout=30000)
|
||||
run_config = CrawlerRunConfig(cache_mode=CacheMode.BYPASS)
|
||||
```
|
||||
|
||||

|
||||
|
||||
*July 17, 2025 • 2 min read*
|
||||
|
||||
---
|
||||
|
||||
A small maintenance release that removes unused code and improves documentation.
|
||||
|
||||
## 🎯 What's Changed
|
||||
|
||||
- **Removed unused StealthConfig** from `crawl4ai/browser_manager.py`

|
||||
|
||||
```python
|
||||
# Removed unused code:
|
||||
from playwright_stealth import StealthConfig
|
||||
stealth_config = StealthConfig(...) # This was never used

|
||||
|
||||
## 🎨 Multi-URL Configurations: One Size Doesn't Fit All
|
||||
|
||||
**The Problem:** You're crawling a mix of documentation sites, blogs, and API endpoints. Each needs different handling—caching for docs, fresh content for news, structured extraction for APIs. Previously, you'd run separate crawls or write complex conditional logic.
|
||||
|
||||
**My Solution:** I implemented URL-specific configurations that let you define different strategies for different URL patterns in a single crawl batch. First match wins, with optional fallback support.
|
||||
|
||||
### Technical Implementation
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
|
||||
|
||||
# Define specialized configs for different content types
|
||||
configs = [
|
||||
# Documentation sites - aggressive caching, include links
|
||||
CrawlerRunConfig(
|
||||
url_matcher=["*docs*", "*documentation*"],
|
||||
cache_mode="write",
|
||||
markdown_generator_options={"include_links": True}
|
||||
),
|
||||
|
||||
# News/blog sites - fresh content, scroll for lazy loading
|
||||
CrawlerRunConfig(
|
||||
url_matcher=lambda url: 'blog' in url or 'news' in url,
|
||||
cache_mode="bypass",
|
||||
js_code="window.scrollTo(0, document.body.scrollHeight/2);"
|
||||
),
|
||||
|
||||
# API endpoints - structured extraction
|
||||
CrawlerRunConfig(
|
||||
url_matcher=["*.json", "*api*"],
|
||||
extraction_strategy=LLMExtractionStrategy(
|
||||
provider="openai/gpt-4o-mini",
|
||||
extraction_type="structured"
|
||||
)
|
||||
),
|
||||
|
||||
# Default fallback for everything else
|
||||
CrawlerRunConfig() # No url_matcher = matches everything
|
||||
]
|
||||
|
||||
# Crawl multiple URLs with appropriate configs
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
results = await crawler.arun_many(
|
||||
urls=[
|
||||
"https://docs.python.org/3/", # → Uses documentation config
|
||||
"https://blog.python.org/", # → Uses blog config
|
||||
"https://api.github.com/users", # → Uses API config
|
||||
"https://example.com/" # → Uses default config
|
||||
],
|
||||
config=configs
|
||||
)
|
||||
```
|
||||
|
||||
**Matching Capabilities:**
|
||||
- **String Patterns**: Wildcards like `"*.pdf"`, `"*/blog/*"`
|
||||
- **Function Matchers**: Lambda functions for complex logic
|
||||
- **Mixed Matchers**: Combine strings and functions with AND/OR logic
|
||||
- **Fallback Support**: Default config when nothing matches
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Mixed Content Sites**: Handle blogs, docs, and downloads in one crawl
|
||||
- **Multi-Domain Crawling**: Different strategies per domain without separate runs
|
||||
- **Reduced Complexity**: No more if/else forests in your extraction code
|
||||
- **Better Performance**: Each URL gets exactly the processing it needs
|
||||
|
||||
## 🕵️ Undetected Browser Support: Stealth Mode Activated
|
||||
|
||||
**The Problem:** Modern websites employ sophisticated bot detection systems. Cloudflare, Akamai, and custom solutions block automated crawlers, limiting access to valuable content.
|
||||
|
||||
**My Solution:** I implemented undetected browser support with a flexible adapter pattern. Now Crawl4AI can bypass most bot detection systems using stealth techniques.
|
||||
|
||||
### Technical Implementation
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig
|
||||
|
||||
# Enable undetected mode for stealth crawling
|
||||
browser_config = BrowserConfig(
|
||||
browser_type="undetected", # Use undetected Chrome
|
||||
headless=True, # Can run headless with stealth
|
||||
extra_args=[
|
||||
"--disable-blink-features=AutomationControlled",
|
||||
"--disable-web-security",
|
||||
"--disable-features=VizDisplayCompositor"
|
||||
]
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
# This will bypass most bot detection systems
|
||||
result = await crawler.arun("https://protected-site.com")
|
||||
|
||||
if result.success:
|
||||
print("✅ Successfully bypassed bot detection!")
|
||||
print(f"Content length: {len(result.markdown)}")
|
||||
```
|
||||
|
||||
**Advanced Anti-Bot Strategies:**
|
||||
|
||||
```python
|
||||
# Combine multiple stealth techniques
|
||||
from crawl4ai import CrawlerRunConfig
|
||||
|
||||
config = CrawlerRunConfig(
|
||||
# Random user agents and headers
|
||||
headers={
|
||||
"Accept-Language": "en-US,en;q=0.9",
|
||||
"Accept-Encoding": "gzip, deflate, br",
|
||||
"DNT": "1"
|
||||
},
|
||||
|
||||
# Human-like behavior simulation
|
||||
js_code="""
|
||||
// Random mouse movements
|
||||
const simulateHuman = () => {
|
||||
const event = new MouseEvent('mousemove', {
|
||||
clientX: Math.random() * window.innerWidth,
|
||||
clientY: Math.random() * window.innerHeight
|
||||
});
|
||||
document.dispatchEvent(event);
|
||||
};
|
||||
setInterval(simulateHuman, 100 + Math.random() * 200);
|
||||
|
||||
// Random scrolling
|
||||
const randomScroll = () => {
|
||||
const scrollY = Math.random() * (document.body.scrollHeight - window.innerHeight);
|
||||
window.scrollTo(0, scrollY);
|
||||
};
|
||||
setTimeout(randomScroll, 500 + Math.random() * 1000);
|
||||
""",
|
||||
|
||||
# Delay to appear more human
|
||||
delay_before_return_html=2.0
|
||||
)
|
||||
|
||||
result = await crawler.arun("https://bot-protected-site.com", config=config)
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Enterprise Scraping**: Access previously blocked corporate sites and databases
|
||||
- **Market Research**: Gather data from competitor sites with protection
|
||||
- **Price Monitoring**: Track e-commerce sites that block automated access
|
||||
- **Content Aggregation**: Collect news and social media despite anti-bot measures
|
||||
- **Compliance Testing**: Verify your own site's bot protection effectiveness
|
||||
|
||||
## 🧠 Memory Monitoring & Optimization
|
||||
|
||||
**The Problem:** Long-running crawl sessions consuming excessive memory, especially when processing large batches or heavy JavaScript sites.
|
||||
|
||||
**My Solution:** Built comprehensive memory monitoring and optimization utilities that track usage patterns and provide actionable insights.
|
||||
|
||||
### Memory Tracking Implementation
|
||||
|
||||
```python
|
||||
from crawl4ai.memory_utils import MemoryMonitor, get_memory_info
|
||||
|
||||
# Monitor memory during crawling
|
||||
monitor = MemoryMonitor()
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
# Start monitoring
|
||||
monitor.start_monitoring()
|
||||
|
||||
# Perform memory-intensive operations
|
||||
results = await crawler.arun_many([
|
||||
"https://heavy-js-site.com",
|
||||
"https://large-images-site.com",
|
||||
"https://dynamic-content-site.com"
|
||||
])
|
||||
|
||||
# Get detailed memory report
|
||||
memory_report = monitor.get_report()
|
||||
print(f"Peak memory usage: {memory_report['peak_mb']:.1f} MB")
|
||||
print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
|
||||
|
||||
# Automatic cleanup suggestions
|
||||
if memory_report['peak_mb'] > 1000: # > 1GB
|
||||
print("💡 Consider batch size optimization")
|
||||
print("💡 Enable aggressive garbage collection")
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Production Stability**: Prevent memory-related crashes in long-running services
|
||||
- **Cost Optimization**: Right-size server resources based on actual usage
|
||||
- **Performance Tuning**: Identify memory bottlenecks and optimization opportunities
|
||||
- **Scalability Planning**: Understand memory patterns for horizontal scaling
|
||||
|
||||
## 📊 Enhanced Table Extraction
|
||||
|
||||
**The Problem:** Table data was accessed through the generic `result.media` interface, making DataFrame conversion cumbersome and unclear.
|
||||
|
||||
**My Solution:** Dedicated `result.tables` interface with direct DataFrame conversion and improved detection algorithms.
|
||||
|
||||
### New Table Access Pattern
|
||||
|
||||
```python
|
||||
# Old way (deprecated)
|
||||
# tables_data = result.media.get('tables', [])
|
||||
|
||||
# New way (v0.7.3+)
|
||||
result = await crawler.arun("https://site-with-tables.com")
|
||||
|
||||
# Direct table access
|
||||
if result.tables:
|
||||
print(f"Found {len(result.tables)} tables")
|
||||
|
||||
# Convert to pandas DataFrame instantly
|
||||
import pandas as pd
|
||||
|
||||
for i, table in enumerate(result.tables):
|
||||
df = pd.DataFrame(table['data'])
|
||||
print(f"Table {i}: {df.shape[0]} rows × {df.shape[1]} columns")
|
||||
print(df.head())
|
||||
|
||||
# Table metadata
|
||||
print(f"Source: {table.get('source_xpath', 'Unknown')}")
|
||||
print(f"Headers: {table.get('headers', [])}")
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Data Analysis**: Faster transition from web data to analysis-ready DataFrames
|
||||
- **ETL Pipelines**: Cleaner integration with data processing workflows
|
||||
- **Reporting**: Simplified table extraction for automated reporting systems
|
||||
|
||||

|
||||
## 🐳 Docker: Flexible LLM Provider Configuration
|
||||
|
||||
**The Problem:** Hardcoded LLM providers in Docker deployments. Want to switch from OpenAI to Groq? Rebuild and redeploy. Testing different models? Multiple Docker images.
|
||||
|
||||
**My Solution:** Configure LLM providers via environment variables. Switch providers without touching code or rebuilding images.
|
||||
|
||||
### Deployment Flexibility
|
||||
|
||||
```bash
|
||||
# Option 1: Direct environment variables
|
||||
docker run -d \
|
||||
-e LLM_PROVIDER="groq/llama-3.2-3b-preview" \
|
||||
-e GROQ_API_KEY="your-key" \
|
||||
-p 11235:11235 \
|
||||
unclecode/crawl4ai:latest
|
||||
|
||||
# Option 2: Using .llm.env file (recommended for production)
|
||||
# Create .llm.env file:
|
||||
# LLM_PROVIDER=openai/gpt-4o-mini
|
||||
# OPENAI_API_KEY=your-openai-key
|
||||
# GROQ_API_KEY=your-groq-key
|
||||
|
||||
docker run -d \
|
||||
--env-file .llm.env \
|
||||
-p 11235:11235 \
|
||||
unclecode/crawl4ai:latest
|
||||
```
|
||||
|
||||
Override per request when needed:
|
||||
```python
|
||||
# Use default provider from .llm.env
|
||||
response = requests.post("http://localhost:11235/crawl", json={
|
||||
"url": "https://example.com",
|
||||
"extraction_strategy": {"type": "llm"}
|
||||
})
|
||||
|
||||
# Override to use different provider for this specific request
|
||||
response = requests.post("http://localhost:11235/crawl", json={
|
||||
"url": "https://complex-page.com",
|
||||
"extraction_strategy": {
|
||||
"type": "llm",
|
||||
"provider": "openai/gpt-4" # Override default
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Cost Optimization**: Use cheaper models for simple tasks, premium for complex
|
||||
- **A/B Testing**: Compare provider performance without deployment changes
|
||||
- **Fallback Strategies**: Switch providers on-the-fly during outages
|
||||
- **Development Flexibility**: Test locally with one provider, deploy with another
|
||||
- **Secure Configuration**: Keep API keys in `.llm.env` file, not in commands
|
||||

|
||||
## 🚀 LLMTableExtraction: Revolutionary Table Processing
|
||||
|
||||
**The Problem:** Complex tables with rowspan, colspan, nested structures, or massive datasets that traditional HTML parsing can't handle effectively. Large tables that exceed token limits crash extraction processes.
|
||||
|
||||
**My Solution:** I developed LLMTableExtraction—an intelligent table extraction strategy that uses Large Language Models with automatic chunking to handle tables of any size and complexity.
|
||||
|
||||
### Technical Implementation
|
||||
|
||||
```python
|
||||
from crawl4ai import (
|
||||
AsyncWebCrawler,
|
||||
CrawlerRunConfig,
|
||||
LLMConfig,
|
||||
LLMTableExtraction,
|
||||
CacheMode
|
||||
)
|
||||
|
||||
# Configure LLM for table extraction
|
||||
llm_config = LLMConfig(
|
||||
provider="openai/gpt-4.1-mini",
|
||||
api_token="env:OPENAI_API_KEY",
|
||||
temperature=0.1, # Low temperature for consistency
|
||||
max_tokens=32000
|
||||
)
|
||||
|
||||
# Create intelligent table extraction strategy
|
||||
table_strategy = LLMTableExtraction(
|
||||
llm_config=llm_config,
|
||||
verbose=True,
|
||||
max_tries=2,
|
||||
enable_chunking=True, # Handle massive tables
|
||||
chunk_token_threshold=5000, # Smart chunking threshold
|
||||
overlap_threshold=100, # Maintain context between chunks
|
||||
extraction_type="structured" # Get structured data output
|
||||
)
|
||||
|
||||
# Apply to crawler configuration
|
||||
config = CrawlerRunConfig(
|
||||
table_extraction_strategy=table_strategy,
|
||||
cache_mode=CacheMode.BYPASS
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
# Extract complex tables with intelligence
|
||||
result = await crawler.arun(
|
||||
"https://en.wikipedia.org/wiki/List_of_countries_by_GDP",
|
||||
config=config
|
||||
)
|
||||
|
||||
# Access extracted tables directly
|
||||
for i, table in enumerate(result.tables):
|
||||
print(f"Table {i}: {len(table['data'])} rows × {len(table['headers'])} columns")
|
||||
|
||||
# Convert to pandas DataFrame instantly
|
||||
import pandas as pd
|
||||
df = pd.DataFrame(table['data'], columns=table['headers'])
|
||||
print(df.head())
|
||||
```
|
||||
|
||||
**Intelligent Chunking for Massive Tables:**
|
||||
|
||||
```python
|
||||
# Handle tables that exceed token limits
|
||||
large_table_strategy = LLMTableExtraction(
|
||||
llm_config=llm_config,
|
||||
enable_chunking=True,
|
||||
chunk_token_threshold=3000, # Conservative threshold
|
||||
overlap_threshold=150, # Preserve context
|
||||
max_concurrent_chunks=3, # Parallel processing
|
||||
merge_strategy="intelligent" # Smart chunk merging
|
||||
)
|
||||
|
||||
# Process Wikipedia comparison tables, financial reports, etc.
|
||||
config = CrawlerRunConfig(
|
||||
table_extraction_strategy=large_table_strategy,
|
||||
# Target specific table containers
|
||||
css_selector="div.wikitable, table.sortable",
|
||||
delay_before_return_html=2.0
|
||||
)
|
||||
|
||||
result = await crawler.arun(
|
||||
"https://en.wikipedia.org/wiki/Comparison_of_operating_systems",
|
||||
config=config
|
||||
)
|
||||
|
||||
# Tables are automatically chunked, processed, and merged
|
||||
print(f"Extracted {len(result.tables)} complex tables")
|
||||
for table in result.tables:
|
||||
print(f"Merged table: {len(table['data'])} total rows")
|
||||
```
|
||||
|
||||
**Advanced Features:**
|
||||
|
||||
- **Intelligent Chunking**: Automatically splits massive tables while preserving structure
|
||||
- **Context Preservation**: Overlapping chunks maintain column relationships
|
||||
- **Parallel Processing**: Concurrent chunk processing for speed
|
||||
- **Smart Merging**: Reconstructs complete tables from processed chunks
|
||||
- **Complex Structure Support**: Handles rowspan, colspan, nested tables
|
||||
- **Metadata Extraction**: Captures table context, captions, and relationships
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Financial Analysis**: Extract complex earnings tables and financial statements
|
||||
- **Research & Academia**: Process large datasets from Wikipedia, research papers
|
||||
- **E-commerce**: Handle product comparison tables with complex layouts
|
||||
- **Government Data**: Extract census data, statistical tables from official sources
|
||||
- **Competitive Intelligence**: Process competitor pricing and feature tables
|
||||
|
||||
## ⚡ Enhanced Concurrency: True Performance Gains
|
||||
|
||||
**The Problem:** The `arun_many()` method wasn't achieving true concurrency for fast-completing tasks, leading to sequential processing bottlenecks in batch operations.
|
||||
|
||||
**My Solution:** I implemented true concurrency improvements in the dispatcher that enable genuine parallel processing for fast-completing tasks.
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
```python
|
||||
# Before v0.7.4: Sequential-like behavior for fast tasks
|
||||
# After v0.7.4: True concurrency
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
# These will now run with true concurrency
|
||||
urls = [
|
||||
"https://httpbin.org/delay/1",
|
||||
"https://httpbin.org/delay/1",
|
||||
"https://httpbin.org/delay/1",
|
||||
"https://httpbin.org/delay/1"
|
||||
]
|
||||
|
||||
# Processes in truly parallel fashion
|
||||
results = await crawler.arun_many(urls)
|
||||
|
||||
# Performance improvement: ~4x faster for fast-completing tasks
|
||||
print(f"Processed {len(results)} URLs with true concurrency")
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **API Crawling**: 3-4x faster processing of REST endpoints and API documentation
|
||||
- **Batch URL Processing**: Significant speedup for large URL lists
|
||||
- **Monitoring Systems**: Faster health checks and status page monitoring
|
||||
- **Data Aggregation**: Improved performance for real-time data collection
|
||||
|
||||
## 🧹 Memory Management Refactor: Cleaner Architecture
|
||||
|
||||
**The Problem:** Memory utilities were scattered and difficult to maintain, with potential import conflicts and unclear organization.
|
||||
|
||||
**My Solution:** I consolidated all memory-related utilities into the main `utils.py` module, creating a cleaner, more maintainable architecture.
|
||||
|
||||
### Improved Memory Handling
|
||||
|
||||
```python
|
||||
# All memory utilities now consolidated
|
||||
from crawl4ai.utils import get_true_memory_usage_percent, MemoryMonitor
|
||||
|
||||
# Enhanced memory monitoring
|
||||
monitor = MemoryMonitor()
|
||||
monitor.start_monitoring()
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
# Memory-efficient batch processing
|
||||
results = await crawler.arun_many(large_url_list)
|
||||
|
||||
# Get accurate memory metrics
|
||||
memory_usage = get_true_memory_usage_percent()
|
||||
memory_report = monitor.get_report()
|
||||
|
||||
print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
|
||||
print(f"Peak usage: {memory_report['peak_mb']:.1f} MB")
|
||||
```
|
||||
|
||||
**Expected Real-World Impact:**
|
||||
- **Production Stability**: More reliable memory tracking and management
|
||||
- **Code Maintainability**: Cleaner architecture for easier debugging
|
||||
- **Import Clarity**: Resolved potential conflicts and import issues
|
||||
- **Developer Experience**: Simpler API for memory monitoring
|
||||
|
||||
## 🔧 Critical Stability Fixes
|
||||
|
||||
### Browser Manager Race Condition Resolution
|
||||
|
||||
**The Problem:** Concurrent page creation in persistent browser contexts caused "Target page/context closed" errors during high-concurrency operations.
|
||||
|
||||
**My Solution:** Implemented thread-safe page creation with proper locking mechanisms.
|
||||
|
||||
```python
|
||||
# Fixed: Safe concurrent page creation
|
||||
browser_config = BrowserConfig(
|
||||
browser_type="chromium",
|
||||
use_persistent_context=True, # Now thread-safe
|
||||
max_concurrent_sessions=10 # Safely handle concurrent requests
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
# These concurrent operations are now stable
|
||||
tasks = [crawler.arun(url) for url in url_list]
|
||||
results = await asyncio.gather(*tasks) # No more race conditions
|
||||
```
|
||||
|
||||
### Enhanced Browser Profiler
|
||||
|
||||
**The Problem:** Inconsistent keyboard handling across platforms and unreliable quit mechanisms.
|
||||
|
||||
**My Solution:** Cross-platform keyboard listeners with improved quit handling.
|
||||
|
||||
### Advanced URL Processing
|
||||
|
||||
**The Problem:** Raw URL formats (`raw://` and `raw:`) weren't properly handled, and base tag link resolution was incomplete.
|
||||
|
||||
**My Solution:** Enhanced URL preprocessing and base tag support.
|
||||
|
||||
```python
|
||||
# Now properly handles all URL formats
|
||||
urls = [
|
||||
"https://example.com",
|
||||
"raw://static-html-content",
|
||||
"raw:file://local-file.html"
|
||||
]
|
||||
|
||||
# Base tag links are now correctly resolved
|
||||
config = CrawlerRunConfig(
|
||||
include_links=True, # Links properly resolved with base tags
|
||||
resolve_absolute_urls=True
|
||||
)
|
||||
```
|
||||
|
||||
## 🛡️ Enhanced Proxy Configuration
|
||||
|
||||
**The Problem:** Proxy configuration only accepted specific formats, limiting flexibility.
|
||||
|
||||
**My Solution:** Enhanced ProxyConfig to support both dictionary and string formats.
|
||||
|
||||
```python
|
||||
# Multiple proxy configuration formats now supported
|
||||
from crawl4ai import BrowserConfig, ProxyConfig
|
||||
|
||||
# String format
|
||||
proxy_config = ProxyConfig("http://proxy.example.com:8080")
|
||||
|
||||
# Dictionary format
|
||||
proxy_config = ProxyConfig({
|
||||
"server": "http://proxy.example.com:8080",
|
||||
"username": "user",
|
||||
"password": "pass"
|
||||
})
|
||||
|
||||
# Use with crawler
|
||||
browser_config = BrowserConfig(proxy_config=proxy_config)
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun("https://httpbin.org/ip")
|
||||
```
|
||||
|
||||

### browser_manager.py
|
||||
|
||||
| Function | What it does |
|
||||
|---|---|
|
||||
| `ManagedBrowser.build_browser_flags` | Returns baseline Chromium CLI flags, disables GPU and sandbox, plugs locale, timezone, stealth tweaks, and any extras from `BrowserConfig`. |
|
||||
| `ManagedBrowser.__init__` | Stores config and logger, creates temp dir, preps internal state. |
|
||||
| `ManagedBrowser.start` | Spawns or connects to the Chromium process, returns its CDP endpoint plus the `subprocess.Popen` handle. |
|
||||
| `ManagedBrowser._initial_startup_check` | Pings the CDP endpoint once to be sure the browser is alive, raises if not. |
|
||||
| `ManagedBrowser._monitor_browser_process` | Async-loops on the subprocess, logs exits or crashes, restarts if policy allows. |
|
||||
| `ManagedBrowser._get_browser_path_WIP` | Old helper that maps OS + browser type to an executable path. |
|

|
||||
| `BrowserManager.setup_context` | Applies locale, geolocation, permissions, cookies, and UA overrides on a fresh context. |
|
||||
| `BrowserManager.create_browser_context` | Internal helper that actually calls `browser.new_context(**options)` after running `setup_context`. |
|
||||
| `BrowserManager._make_config_signature` | Hashes the non-ephemeral parts of `CrawlerRunConfig` so contexts can be reused safely. |
|
||||
| `BrowserManager.get_page` | Returns a ready `Page` for a given session id, reusing an existing one or creating a new context/page, injects helper scripts, updates `last_used`. |
|

| **browser status** | – | Prints whether the always-on *builtin* browser is running, shows its CDP URL, PID, start time. |
|
||||
| **browser stop** | – | Kills the builtin browser and deletes its status file. |
|
||||
| **browser view** | `--url, -u` URL *(optional)* | Pops a visible window of the builtin browser, navigates to `URL` or `about:blank`. |
|
||||
| **config list** | – | Dumps every global setting, showing current value, default, and description. |
|
||||
| **config get** | `key` | Prints the value of a single setting, falls back to default if unset. |
|
||||
| **config set** | `key value` | Persists a new value in the global config (stored under `~/.crawl4ai/config.yml`). |
|
||||
| **examples** | – | Just spits out real-world CLI usage samples. |
|
||||
| **crawl** | `url` *(positional)*<br>`--browser-config,-B` path<br>`--crawler-config,-C` path<br>`--filter-config,-f` path<br>`--extraction-config,-e` path<br>`--json-extract,-j` [desc]\*<br>`--schema,-s` path<br>`--browser,-b` k=v list<br>`--crawler,-c` k=v list<br>`--output,-o` all,json,markdown,md,markdown-fit,md-fit *(default all)*<br>`--output-file,-O` path<br>`--bypass-cache,-b` *(flag, default true — note flag reuse)*<br>`--question,-q` str<br>`--verbose,-v` *(flag)*<br>`--profile,-p` profile-name | One-shot crawl + extraction. Builds `BrowserConfig` and `CrawlerRunConfig` from inline flags or separate YAML/JSON files, runs `AsyncWebCrawler.run()`, can route through a named saved profile and pipe the result to stdout or a file. |
|
||||
| **(default)** | Same flags as **crawl**, plus `--example` | Shortcut so you can type just `crwl https://site.com`. When first arg is not a known sub-command, it falls through to *crawl*. |
|
||||
|
||||
\* `--json-extract/-j` with no value turns on LLM-based JSON extraction using an auto schema, supplying a string lets you prompt-engineer the field descriptions.
|
||||
|
||||
> Quick mental model
|
||||
> `profiles` = manage identities,
|
||||
> `browser ...` = control long-running headless Chrome that all crawls can piggy-back on,
|
||||
> `crawl` = do the actual work,
|
||||
> `config` = tweak global defaults,
|
||||
> everything else is sugar.
|
||||
|
||||
### Quick-fire “profile” usage cheatsheet
|
||||
|
||||
| Scenario | Command (copy-paste ready) | Notes |
|
||||
|---|---|---|
|
||||
| **Launch interactive Profile Manager UI** | `crwl profiles` | Opens TUI with options: 1 List, 2 Create, 3 Delete, 4 Use-to-crawl, 5 Exit. |
|
||||
| **Create a fresh profile** | `crwl profiles` → choose **2** → name it → browser opens → log in → press **q** in terminal | Saves to `~/.crawl4ai/profiles/<name>`. |
|
||||
| **List saved profiles** | `crwl profiles` → choose **1** | Shows name, browser type, size, last-modified. |
|
||||
| **Delete a profile** | `crwl profiles` → choose **3** → pick the profile index → confirm | Removes the folder. |
|
||||
| **Crawl with a profile (default alias)** | `crwl https://site.com/dashboard -p my-profile` | Keeps login cookies, sets `use_managed_browser=true` under the hood. |
|
||||
| **Crawl + verbose JSON output** | `crwl https://site.com -p my-profile -o json -v` | Any other `crawl` flags work the same. |
|
||||
| **Crawl with extra browser tweaks** | `crwl https://site.com -p my-profile -b "headless=true,viewport_width=1680"` | CLI overrides go on top of the profile. |
|
||||
| **Same but via explicit sub-command** | `crwl crawl https://site.com -p my-profile` | Identical to default alias. |
|
||||
| **Use profile from inside Profile Manager** | `crwl profiles` → choose **4** → pick profile → enter URL → follow prompts | Handy when demo-ing to non-CLI folks. |
|
||||
| **One-off crawl with a profile folder path (no name lookup)** | `crwl https://site.com -b "user_data_dir=$HOME/.crawl4ai/profiles/my-profile,use_managed_browser=true"` | Bypasses registry, useful for CI scripts. |
|
||||
| **Launch a dev browser on CDP port with the same identity** | `crwl cdp -d $HOME/.crawl4ai/profiles/my-profile -P 9223` | Lets Puppeteer/Playwright attach for debugging. |

# Adaptive Crawling Examples
|
||||
|
||||
This directory contains examples demonstrating various aspects of Crawl4AI's Adaptive Crawling feature.
|
||||
|
||||
## Examples Overview
|
||||
|
||||
### 1. `basic_usage.py`
|
||||
- Simple introduction to adaptive crawling
|
||||
- Uses default statistical strategy
|
||||
- Shows how to get crawl statistics and relevant content
|
||||
|
||||
### 2. `embedding_strategy.py` ⭐ NEW
|
||||
- Demonstrates the embedding-based strategy for semantic understanding
|
||||
- Shows query expansion and irrelevance detection
|
||||
- Includes configuration for both local and API-based embeddings
|
||||
|
||||
### 3. `embedding_vs_statistical.py` ⭐ NEW
|
||||
- Direct comparison between statistical and embedding strategies
|
||||
- Helps you choose the right strategy for your use case
|
||||
- Shows performance and accuracy trade-offs
|
||||
|
||||
### 4. `embedding_configuration.py` ⭐ NEW
|
||||
- Advanced configuration options for embedding strategy
|
||||
- Parameter tuning guide for different scenarios
|
||||
- Examples for research, exploration, and quality-focused crawling
|
||||
|
||||
### 5. `advanced_configuration.py`
|
||||
- Shows various configuration options for both strategies
|
||||
- Demonstrates threshold tuning and performance optimization
|
||||
|
||||
### 6. `custom_strategies.py`
|
||||
- How to implement your own crawling strategy
|
||||
- Extends the base CrawlStrategy class
|
||||
- Advanced use case for specialized requirements
|
||||
|
||||
### 7. `export_import_kb.py`
|
||||
- Export crawled knowledge base to JSONL
|
||||
- Import and continue crawling from saved state
|
||||
- Useful for building persistent knowledge bases
|
||||
|
||||
## Quick Start
|
||||
|
||||
For your first adaptive crawling experience, run:
|
||||
|
||||
```bash
|
||||
python basic_usage.py
|
||||
```
|
||||
|
||||
To try the new embedding strategy with semantic understanding:
|
||||
|
||||
```bash
|
||||
python embedding_strategy.py
|
||||
```
|
||||
|
||||
To compare strategies and see which works best for your use case:
|
||||
|
||||
```bash
|
||||
python embedding_vs_statistical.py
|
||||
```
|
||||
|
||||
## Strategy Selection Guide
|
||||
|
||||
### Use Statistical Strategy (Default) When:
|
||||
- Working with technical documentation
|
||||
- Queries contain specific terms or code
|
||||
- Speed is critical
|
||||
- No API access available
|
||||
|
||||
### Use Embedding Strategy When:
|
||||
- Queries are conceptual or ambiguous
|
||||
- Need semantic understanding beyond exact matches
|
||||
- Want to detect irrelevant content
|
||||
- Working with diverse content sources
|
||||
|
||||
## Requirements
|
||||
|
||||
- Crawl4AI installed
|
||||
- For embedding strategy with local models: `sentence-transformers`
|
||||
- For embedding strategy with OpenAI: Set `OPENAI_API_KEY` environment variable
