|
||||
|
||||
## [0.6.0rc1] ‑ 2025‑04‑22
|
||||
|
||||
### Added
|
||||
- Browser pooling with page pre‑warming and fine‑grained **geolocation, locale, and timezone** controls
|
||||
- Crawler pool manager (SDK + Docker API) for smarter resource allocation
|
||||
- Network & console log capture plus MHTML snapshot export
|
||||
- **Table extractor**: turn HTML `<table>`s into DataFrames or CSV with one flag
|
||||
- High‑volume stress‑test framework in `tests/memory` and API load scripts
|
||||
- MCP protocol endpoints with socket & SSE support; playground UI scaffold
|
||||
- Docs v2 revamp: TOC, GitHub badge, copy‑code buttons, Docker API demo
|
||||
- “Ask AI” helper button *(work‑in‑progress, shipping soon)*
|
||||
- New examples: geo‑location usage, network/console capture, Docker API, markdown source selection, crypto analysis
|
||||
- Expanded automated test suites for browser, Docker, MCP and memory benchmarks
|
||||
|
||||
### Changed
|
||||
- Consolidated and renamed browser strategies; legacy docker strategy modules removed
|
||||
- `ProxyConfig` moved to `async_configs`
|
||||
- Server migrated to pool‑based crawler management
|
||||
- FastAPI validators replace custom query validation
|
||||
- Docker build now uses Chromium base image
|
||||
- Large‑scale repo tidy‑up (≈36 k insertions, ≈5 k deletions)
|
||||
|
||||
### Fixed
|
||||
- Async crawler session leak, duplicate‑visit handling, URL normalisation
|
||||
- Target‑element regressions in scraping strategies
|
||||
- Logged‑URL readability, encoded‑URL decoding, middle truncation for long URLs
|
||||
- Closed issues: #701, #733, #756, #774, #804, #822, #839, #841, #842, #843, #867, #902, #911
|
||||
|
||||
### Removed
|
||||
- Obsolete modules under `crawl4ai/browser/*` superseded by the new pooled browser layer
|
||||
|
||||
### Deprecated
|
||||
- Old markdown generator names now alias `DefaultMarkdownGenerator` and emit warnings
|
||||
|
||||
---
|
||||
|
||||
#### Upgrade notes
|
||||
1. Update any direct imports from `crawl4ai/browser/*` to the new pooled browser modules
|
||||
2. If you override `AsyncPlaywrightCrawlerStrategy.get_page`, adopt the new signature
|
||||
3. Rebuild Docker images to pull the new Chromium layer
|
||||
4. Switch to `DefaultMarkdownGenerator` (or silence the deprecation warning)

## [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.
|
||||
5. Updated `run_benchmark.py` to provide clickable `file://` links to generated reports in the terminal output.
|
||||
6. Updated `USAGE.md` with comprehensive parameter descriptions reflecting the final script arguments.
|
||||
7. Updated `run_all.sh` wrapper to correctly invoke `run_benchmark.py` with flexible arguments.
|
||||
|
||||
**Details of Changes:**
|
||||
|
||||
1. **Parameter Correction (`--max-sessions`)**:
|
||||
* 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`.
|
||||
- `run_benchmark.py`: Changed argument handling, updated configs, calls `stress_test_sdk.py`.
|
||||
- `run_all.sh`: Updated to call `run_benchmark.py` correctly.
|
||||
- `USAGE.md`: Updated documentation extensively.
|
||||
- `benchmark_report.py`: (Assumed modifications for dark theme and viz fixes).
|
||||
|
||||
**Testing:**
|
||||
- Verified that `--max-sessions` correctly limits concurrency via the `CrawlerMonitor` output.
|
||||
- Confirmed that custom arguments passed to `run_benchmark.py` are forwarded to `stress_test_sdk.py`.
|
||||
- Validated clickable links work in supporting terminals.
|
||||
- Ensured documentation matches the final script parameters and behavior.
|
||||
|
||||
**Why These Changes:**
|
||||
These refinements correct the fundamental approach of the stress test to align with `crawl4ai`'s actual architecture and intended usage:
|
||||
1. Ensures the test evaluates the correct components (`arun_many`, `MemoryAdaptiveDispatcher`).
|
||||
2. Makes test configurations more accurate and flexible.
|
||||
3. Improves the usability of the testing framework through better argument handling and documentation.
|
||||
|

|
||||
|
||||
## [2025-04-09] Added MHTML Capture Feature
|
||||
|
||||
**Feature:** MHTML snapshot capture of crawled pages
|
||||
|
||||
**Changes Made:**
|
||||
1. Added `capture_mhtml: bool = False` parameter to `CrawlerRunConfig` class
|
||||
2. Added `mhtml: Optional[str] = None` field to `CrawlResult` model
|
||||
3. Added `mhtml_data: Optional[str] = None` field to `AsyncCrawlResponse` class
|
||||
4. Implemented `capture_mhtml()` method in `AsyncPlaywrightCrawlerStrategy` class to capture MHTML via CDP
|
||||
5. Modified the crawler to capture MHTML when enabled and pass it to the result
|
||||
|
||||
**Implementation Details:**
|
||||
- MHTML capture uses Chrome DevTools Protocol (CDP) via Playwright's CDP session API
|
||||
- The implementation waits for page to fully load before capturing MHTML content
|
||||
- Enhanced waiting for JavaScript content with requestAnimationFrame for better JS content capture
|
||||
- We ensure all browser resources are properly cleaned up after capture
|
||||
|
||||
**Files Modified:**
|
||||
- `crawl4ai/models.py`: Added the mhtml field to CrawlResult
|
||||
- `crawl4ai/async_configs.py`: Added capture_mhtml parameter to CrawlerRunConfig
|
||||
- `crawl4ai/async_crawler_strategy.py`: Implemented MHTML capture logic
|
||||
- `crawl4ai/async_webcrawler.py`: Added mapping from AsyncCrawlResponse.mhtml_data to CrawlResult.mhtml
|
||||
|
||||
**Testing:**
|
||||
- Created comprehensive tests in `tests/20241401/test_mhtml.py` covering:
|
||||
- Capturing MHTML when enabled
|
||||
- Ensuring mhtml is None when disabled explicitly
|
||||
- Ensuring mhtml is None by default
|
||||
- Capturing MHTML on JavaScript-enabled pages
|
||||
|
||||
**Challenges:**
|
||||
- Had to improve page loading detection to ensure JavaScript content was fully rendered
|
||||
- Tests needed to be run independently due to Playwright browser instance management
|
||||
- Modified test expected content to match actual MHTML output
|
||||
|
||||
**Why This Feature:**
|
||||
The MHTML capture feature allows users to capture complete web pages including all resources (CSS, images, etc.) in a single file. This is valuable for:
|
||||
1. Offline viewing of captured pages
|
||||
2. Creating permanent snapshots of web content for archival
|
||||
3. Ensuring consistent content for later analysis, even if the original site changes
|
||||
|
||||
**Future Enhancements to Consider:**
|
||||
- Add option to save MHTML to file
|
||||
- Support for filtering what resources get included in MHTML
|
||||
- Add support for specifying MHTML capture options
|
||||
|
||||
## [2025-04-10] Added Network Request and Console Message Capturing
|
||||
|
||||
**Feature:** Comprehensive capturing of network requests/responses and browser console messages during crawling
|
||||
|
||||
**Changes Made:**
|
||||
1. Added `capture_network_requests: bool = False` and `capture_console_messages: bool = False` parameters to `CrawlerRunConfig` class
|
||||
2. Added `network_requests: Optional[List[Dict[str, Any]]] = None` and `console_messages: Optional[List[Dict[str, Any]]] = None` fields to both `AsyncCrawlResponse` and `CrawlResult` models
|
||||
3. Implemented event listeners in `AsyncPlaywrightCrawlerStrategy._crawl_web()` to capture browser network events and console messages
|
||||
4. Added proper event listener cleanup in the finally block to prevent resource leaks
|
||||
5. Modified the crawler flow to pass captured data from AsyncCrawlResponse to CrawlResult
|
||||
|
||||
**Implementation Details:**
|
||||
- Network capture uses Playwright event listeners (`request`, `response`, and `requestfailed`) to record all network activity
|
||||
- Console capture uses Playwright event listeners (`console` and `pageerror`) to record console messages and errors
|
||||
- Each network event includes metadata like URL, headers, status, and timing information
|
||||
- Each console message includes type, text content, and source location when available
|
||||
- All captured events include timestamps for chronological analysis
|
||||
- Error handling ensures even failed capture attempts won't crash the main crawling process
|
||||
|
||||
**Files Modified:**
|
||||
- `crawl4ai/models.py`: Added new fields to AsyncCrawlResponse and CrawlResult
|
||||
- `crawl4ai/async_configs.py`: Added new configuration parameters to CrawlerRunConfig
|
||||
- `crawl4ai/async_crawler_strategy.py`: Implemented capture logic using event listeners
|
||||
- `crawl4ai/async_webcrawler.py`: Added data transfer from AsyncCrawlResponse to CrawlResult
|
||||
|
||||
**Documentation:**
|
||||
- Created detailed documentation in `docs/md_v2/advanced/network-console-capture.md`
|
||||
- Added feature to site navigation in `mkdocs.yml`
|
||||
- Updated CrawlResult documentation in `docs/md_v2/api/crawl-result.md`
|
||||
- Created comprehensive example in `docs/examples/network_console_capture_example.py`
|
||||
|
||||
**Testing:**
|
||||
- Created `tests/general/test_network_console_capture.py` with tests for:
|
||||
- Verifying capture is disabled by default
|
||||
- Testing network request capturing
|
||||
- Testing console message capturing
|
||||
- Ensuring both capture types can be enabled simultaneously
|
||||
- Checking correct content is captured in expected formats
|
||||
|
||||
**Challenges:**
|
||||
- Initial implementation had synchronous/asynchronous mismatches in event handlers
|
||||
- Needed to fix type of property access vs. method calls in handlers
|
||||
- Required careful cleanup of event listeners to prevent memory leaks
|
||||
|
||||
**Why This Feature:**
|
||||
The network and console capture feature provides deep visibility into web page activity, enabling:
|
||||
1. Debugging complex web applications by seeing all network requests and errors
|
||||
2. Security analysis to detect unexpected third-party requests and data flows
|
||||
3. Performance profiling to identify slow-loading resources
|
||||
4. API discovery in single-page applications
|
||||
5. Comprehensive analysis of web application behavior
|
||||
|
||||
**Future Enhancements to Consider:**
|
||||
- Option to filter captured events by type, domain, or content
|
||||
- Support for capturing response bodies (with size limits)
|
||||
- Aggregate statistics calculation for performance metrics
|
||||
- Integration with visualization tools for network waterfall analysis
|
||||
- Exporting captures in HAR format for use with external tools

PROMPT_EXTRACT_INFERRED_SCHEMA = """Here is the content from the URL:
|
||||
<url>{URL}</url>
|
||||
|
||||
<url_content>
|
||||
{HTML}
|
||||
</url_content>
|
||||
|
||||
Please carefully read the URL content and the user's request. Analyze the page structure and infer the most appropriate JSON schema based on the content and request.
|
||||
|
||||
Extraction Strategy:
|
||||
1. First, determine if the page contains repetitive items (like multiple products, articles, etc.) or a single content item (like a single article or page).
|
||||
2. For repetitive items: Identify the common pattern and extract each instance as a separate JSON object in an array.
|
||||
3. For single content: Extract the key information into a comprehensive JSON object that captures the essential details.
|
||||
|
||||
Extraction instructions:
|
||||
Return the extracted information as a list of JSON objects. For repetitive content, each object in the list should correspond to a distinct item. For single content, you may return just one detailed JSON object. Wrap the entire JSON list in <blocks>...</blocks> XML tags.
|
||||
|
||||
Schema Design Guidelines:
|
||||
- Create meaningful property names that clearly describe the data they contain
|
||||
- Use nested objects for hierarchical information
|
||||
- Use arrays for lists of related items
|
||||
- Include all information requested by the user
|
||||
- Maintain consistency in property names and data structures
|
||||
- Only include properties that are actually present in the content
|
||||
- For dates, prefer ISO format (YYYY-MM-DD)
|
||||
- For prices or numeric values, extract them without currency symbols when possible
|
||||
|
||||
Quality Reflection:
|
||||
Before outputting your final answer, double check that:
|
||||
1. The inferred schema makes logical sense for the type of content
|
||||
2. All requested information is included
|
||||
3. The JSON is valid and could be parsed without errors
|
||||
4. Property names are consistent and descriptive
|
||||
5. The structure is optimal for the type of data being represented
|
||||
|
||||
Avoid Common Mistakes:
|
||||
- Do NOT add any comments using "//" or "#" in the JSON output. It causes parsing errors.
|
||||
- Make sure the JSON is properly formatted with curly braces, square brackets, and commas in the right places.
|
||||
- Do not miss closing </blocks> tag at the end of the JSON output.
|
||||
- Do not generate Python code showing how to do the task; this is your task to extract the information and return it in JSON format.
|
||||
- Ensure consistency in property names across all objects
|
||||
- Don't include empty properties or null values unless they're meaningful
|
||||
- For repetitive content, ensure all objects follow the same schema
|
||||
|
||||
Important: If user specific instruction is provided, then stress significantly on what user is requesting and describing about the schema of end result (if any). If user is requesting to extract specific information, then focus on that and ignore the rest of the content.
|
||||
<user_request>
|
||||
{REQUEST}
|
||||
</user_request>
|
||||
|
||||
Result:
|
||||
Output the final list of JSON objects, wrapped in <blocks>...</blocks> XML tags. Make sure to close the tag properly.
|
||||
|
||||
DO NOT ADD ANY PRE OR POST COMMENTS. JUST RETURN THE JSON OBJECTS INSIDE <blocks>...</blocks> TAGS.
|
||||
|
||||
CRITICAL: The content inside the <blocks> tags MUST be a direct array of JSON objects (starting with '[' and ending with ']'), not a dictionary/object containing an array. For example, use <blocks>[{...}, {...}]</blocks> instead of <blocks>{"items": [{...}, {...}]}</blocks>. This is essential for proper parsing.

# Builtin Browser in Crawl4AI
|
||||
|
||||
This document explains the builtin browser feature in Crawl4AI and how to use it effectively.
|
||||
|
||||
## What is the Builtin Browser?
|
||||
|
||||
The builtin browser is a persistent Chrome instance that Crawl4AI manages for you. It runs in the background and can be used by multiple crawling operations, eliminating the need to start and stop browsers for each crawl.
|
||||
|
||||
Benefits include:
|
||||
- **Faster startup times** - The browser is already running, so your scripts start faster
|
||||
- **Shared resources** - All your crawling scripts can use the same browser instance
|
||||
- **Simplified management** - No need to worry about CDP URLs or browser processes
|
||||
- **Persistent cookies and sessions** - Browser state persists between script runs
|
||||
- **Less resource usage** - Only one browser instance for multiple scripts
|
||||
|
||||
## Using the Builtin Browser
|
||||
|
||||
### In Python Code
|
||||
|
||||
Using the builtin browser in your code is simple:
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig
|
||||
|
||||
# Create browser config with builtin mode
|
||||
browser_config = BrowserConfig(
|
||||
browser_mode="builtin", # This is the key setting!
|
||||
headless=True # Can be headless or not
|
||||
)
|
||||
|
||||
# Create the crawler
|
||||
crawler = AsyncWebCrawler(config=browser_config)
|
||||
|
||||
# Use it - no need to explicitly start()
|
||||
result = await crawler.arun("https://example.com")
|
||||
```
|
||||
|
||||
Key points:
|
||||
1. Set `browser_mode="builtin"` in your BrowserConfig
|
||||
2. No need for explicit `start()` call - the crawler will automatically connect to the builtin browser
|
||||
3. No need to use a context manager or call `close()` - the browser stays running
|
||||
|
||||
### Via CLI
|
||||
|
||||
The CLI provides commands to manage the builtin browser:
|
||||
|
||||
```bash
|
||||
# Start the builtin browser
|
||||
crwl browser start
|
||||
|
||||
# Check its status
|
||||
crwl browser status
|
||||
|
||||
# Open a visible window to see what the browser is doing
|
||||
crwl browser view --url https://example.com
|
||||
|
||||
# Stop it when no longer needed
|
||||
crwl browser stop
|
||||
|
||||
# Restart with different settings
|
||||
crwl browser restart --no-headless
|
||||
```
|
||||
|
||||
When crawling via CLI, simply add the builtin browser mode:
|
||||
|
||||
```bash
|
||||
crwl https://example.com -b "browser_mode=builtin"
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
1. When a crawler with `browser_mode="builtin"` is created:
|
||||
- It checks if a builtin browser is already running
|
||||
- If not, it automatically launches one
|
||||
- It connects to the browser via CDP (Chrome DevTools Protocol)
|
||||
|
||||
2. The browser process continues running after your script exits
|
||||
- This means it's ready for the next crawl
|
||||
- You can manage it via the CLI commands
|
||||
|
||||
3. During installation, Crawl4AI attempts to create a builtin browser automatically
|
||||
|
||||
## Example
|
||||
|
||||
See the [builtin_browser_example.py](builtin_browser_example.py) file for a complete example.
|
||||
|
||||
Run it with:
|
||||
|
||||
```bash
|
||||
python builtin_browser_example.py
|
||||
```
|
||||
|
||||
## When to Use
|
||||
|
||||
The builtin browser is ideal for:
|
||||
- Scripts that run frequently
|
||||
- Development and testing workflows
|
||||
- Applications that need to minimize startup time
|
||||
- Systems where you want to manage browser instances centrally
|
||||
|
||||
You might not want to use it when:
|
||||
- Running one-off scripts
|
||||
- When you need different browser configurations for different tasks
|
||||
- In environments where persistent processes are not allowed
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If you encounter issues:
|
||||
|
||||
1. Check the browser status:
|
||||
```
|
||||
crwl browser status
|
||||
```
|
||||
|
||||
2. Try restarting it:
|
||||
```
|
||||
crwl browser restart
|
||||
```
|
||||
|
||||
3. If problems persist, stop it and let Crawl4AI start a fresh one:
|
||||
```
|
||||
crwl browser stop
|
||||
```

Builtin Browser Example
|

|

This example demonstrates how to use Crawl4AI's builtin browser feature,
|
||||
which simplifies the browser management process. With builtin mode:
|
||||
|
||||
- No need to manually start or connect to a browser
|
||||
- No need to manage CDP URLs or browser processes
|
||||
- Automatically connects to an existing browser or launches one if needed
|
||||
- Browser persists between script runs, reducing startup time
|
||||
- No explicit cleanup or close() calls needed
|
||||
|
||||
The example also demonstrates "auto-starting" where you don't need to explicitly
|
||||
call start() method on the crawler.

This showcases Crawl4AI's flexibility in handling dynamic content and its ability to implement custom logic for even the most challenging crawling tasks."

"3. Within the schema, you define fields, each with its own selector and type.\n",

"4. These field selectors are applied within the context of each base selector element.\n",

"5. The strategy supports nested structures, lists within lists, and various data types.\n",

"6. You can even include computed fields for more complex data manipulation.\n",

"\n",
|

"This approach allows for highly flexible and precise data extraction, transforming semi-structured web content into clean, structured JSON data. It's particularly useful for extracting consistent data patterns from pages like product listings, news articles, or search results.\n",

## 7. Summary
|
||||
## 7. Locale, Timezone, and Geolocation Control
|
||||
|
||||
In addition to using persistent profiles, Crawl4AI supports customizing your browser's locale, timezone, and geolocation settings. These features enhance your identity-based browsing experience by allowing you to control how websites perceive your location and regional settings.
|
||||
|
||||
### Setting Locale and Timezone
|
||||
|
||||
You can set the browser's locale and timezone through `CrawlerRunConfig`:
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
url="https://example.com",
|
||||
config=CrawlerRunConfig(
|
||||
# Set browser locale (language and region formatting)
|
||||
locale="fr-FR", # French (France)
|
||||
|
||||
# Set browser timezone
|
||||
timezone_id="Europe/Paris",
|
||||
|
||||
# Other normal options...
|
||||
magic=True,
|
||||
page_timeout=60000
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
**How it works:**
|
||||
- `locale` affects language preferences, date formats, number formats, etc.
|
||||
- `timezone_id` affects JavaScript's Date object and time-related functionality
|
||||
- These settings are applied when creating the browser context and maintained throughout the session
|
||||
|
||||
### Configuring Geolocation
|
||||
|
||||
Control the GPS coordinates reported by the browser's geolocation API:
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, GeolocationConfig
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
url="https://maps.google.com", # Or any location-aware site
|
||||
config=CrawlerRunConfig(
|
||||
# Configure precise GPS coordinates
|
||||
geolocation=GeolocationConfig(
|
||||
latitude=48.8566, # Paris coordinates
|
||||
longitude=2.3522,
|
||||
accuracy=100 # Accuracy in meters (optional)
|
||||
),
|
||||
|
||||
# This site will see you as being in Paris
|
||||
page_timeout=60000
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
**Important notes:**
|
||||
- When `geolocation` is specified, the browser is automatically granted permission to access location
|
||||
- Websites using the Geolocation API will receive the exact coordinates you specify
|
||||
- This affects map services, store locators, delivery services, etc.
|
||||
- Combined with the appropriate `locale` and `timezone_id`, you can create a fully consistent location profile
|
||||
|
||||
### Combining with Managed Browsers
|
||||
|
||||
These settings work perfectly with managed browsers for a complete identity solution:
|
||||
|
||||
```python
|
||||
from crawl4ai import (
|
||||
AsyncWebCrawler, BrowserConfig, CrawlerRunConfig,
|
||||
GeolocationConfig
|
||||
)
|
||||
|
||||
browser_config = BrowserConfig(
|
||||
use_managed_browser=True,
|
||||
user_data_dir="/path/to/my-profile",
|
||||
browser_type="chromium"
|
||||
)
|
||||
|
||||
crawl_config = CrawlerRunConfig(
|
||||
# Location settings
|
||||
locale="es-MX", # Spanish (Mexico)
|
||||
timezone_id="America/Mexico_City",
|
||||
geolocation=GeolocationConfig(
|
||||
latitude=19.4326, # Mexico City
|
||||
longitude=-99.1332
|
||||
)
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler(config=browser_config) as crawler:
|
||||
result = await crawler.arun(url="https://example.com", config=crawl_config)
|
||||
```
|
||||
|
||||
Combining persistent profiles with precise geolocation and region settings gives you complete control over your digital identity.

||||

||||

# Network Requests & Console Message Capturing
|
||||
|
||||
Crawl4AI can capture all network requests and browser console messages during a crawl, which is invaluable for debugging, security analysis, or understanding page behavior.
|
||||
|
||||
## Configuration
|
||||
|
||||
To enable network and console capturing, use these configuration options:
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
|
||||
# Enable both network request capture and console message capture
|
||||
config = CrawlerRunConfig(
|
||||
capture_network_requests=True, # Capture all network requests and responses
|
||||
capture_console_messages=True # Capture all browser console output
|
||||
)
|
||||
```
|
||||
|
||||
## Example Usage
|
||||
|
||||
```python
|
||||

## Captured Data Structure
|
||||
|
||||
### Network Requests
|
||||
|
||||
The `result.network_requests` contains a list of dictionaries, each representing a network event with these common fields:
|
||||
|
||||
| Field | Description |
|
||||
|-------|-------------|
|
||||
| `event_type` | Type of event: `"request"`, `"response"`, or `"request_failed"` |
|
||||
| `url` | The URL of the request |
|
||||
| `timestamp` | Unix timestamp when the event was captured |
|
||||
|
||||
#### Request Event Fields
|
||||
|
||||
```json
|
||||
{
|
||||
"event_type": "request",
|
||||
"url": "https://example.com/api/data.json",
|
||||
"method": "GET",
|
||||

|
||||
}
|
||||
```
|
||||
|
||||
#### Response Event Fields
|
||||
|
||||
```json

}
|
||||
```
|
||||
|
||||
### Console Messages
|
||||
|
||||
The `result.console_messages` contains a list of dictionaries, each representing a console message with these common fields:
|
||||
|
||||
| Field | Description |

||||
"location": "https://example.com/script.js:123:45",
|
||||
"timestamp": 1633456790.123
|
||||
}
|
||||
```
|
||||
|
||||
## Key Benefits
|
||||
|
||||
- **Full Request Visibility**: Capture all network activity including:
|
||||
- Requests (URLs, methods, headers, post data)
|
||||
- Responses (status codes, headers, timing)
|
||||
- Failed requests (with error messages)
|
||||
|
||||
- **Console Message Access**: View all JavaScript console output:
|
||||
- Log messages
|
||||
- Warnings
|
||||
- Errors with stack traces
|
||||
- Developer debugging information
|
||||
|
||||
- **Debugging Power**: Identify issues such as:
|
||||
- Failed API calls or resource loading
|
||||
- JavaScript errors affecting page functionality
|
||||
- CORS or other security issues
|
||||
- Hidden API endpoints and data flows
|
||||
|
||||
- **Security Analysis**: Detect:
|
||||
- Unexpected third-party requests
|
||||
- Data leakage in request payloads
|
||||
- Suspicious script behavior
|
||||
|
||||
- **Performance Insights**: Analyze:
|
||||
- Request timing data
|
||||
- Resource loading patterns
|
||||
- Potential bottlenecks
|
||||
|
||||
## Use Cases
|
||||
|
||||
1. **API Discovery**: Identify hidden endpoints and data flows in single-page applications
|
||||
2. **Debugging**: Track down JavaScript errors affecting page functionality
|
||||
3. **Security Auditing**: Detect unwanted third-party requests or data leakage
|
||||
4. **Performance Analysis**: Identify slow-loading resources
|
||||
5. **Ad/Tracker Analysis**: Detect and catalog advertising or tracking calls
|
||||
|
||||
This capability is especially valuable for complex sites with heavy JavaScript, single-page applications, or when you need to understand the exact communication happening between a browser and servers.

## 7. Example: Accessing Everything
|
||||
## 7. Network Requests & Console Messages
|
||||
|
||||
When you enable network and console message capturing in `CrawlerRunConfig` using `capture_network_requests=True` and `capture_console_messages=True`, the `CrawlResult` will include these fields:
|
||||
|
||||
### 7.1 **`network_requests`** *(Optional[List[Dict[str, Any]]])*
|
||||
**What**: A list of dictionaries containing information about all network requests, responses, and failures captured during the crawl.
|
||||
**Structure**:
|
||||
- Each item has an `event_type` field that can be `"request"`, `"response"`, or `"request_failed"`.
|
||||
- Request events include `url`, `method`, `headers`, `post_data`, `resource_type`, and `is_navigation_request`.
|
||||
- Response events include `url`, `status`, `status_text`, `headers`, and `request_timing`.
|
||||
- Failed request events include `url`, `method`, `resource_type`, and `failure_text`.
|
||||
- All events include a `timestamp` field.
|
||||
|
||||
**Usage**:
|
||||
```python
|
||||
if result.network_requests:
|
||||
# Count different types of events
|
||||
requests = [r for r in result.network_requests if r.get("event_type") == "request"]
|
||||
responses = [r for r in result.network_requests if r.get("event_type") == "response"]
|
||||
failures = [r for r in result.network_requests if r.get("event_type") == "request_failed"]
|
||||
|
||||
print(f"Captured {len(requests)} requests, {len(responses)} responses, and {len(failures)} failures")
|
||||
|
||||
# Analyze API calls
|
||||
api_calls = [r for r in requests if "api" in r.get("url", "")]
|
||||
|
||||
# Identify failed resources
|
||||
for failure in failures:
|
||||
print(f"Failed to load: {failure.get('url')} - {failure.get('failure_text')}")
|
||||
```
|
||||
|
||||
### 7.2 **`console_messages`** *(Optional[List[Dict[str, Any]]])*
|
||||
**What**: A list of dictionaries containing all browser console messages captured during the crawl.
|
||||
**Structure**:
|
||||
- Each item has a `type` field indicating the message type (e.g., `"log"`, `"error"`, `"warning"`, etc.).
|
||||
- The `text` field contains the actual message text.
|
||||
- Some messages include `location` information (URL, line, column).
|
||||
- All messages include a `timestamp` field.
|
||||
|
||||
**Usage**:
|
||||
```python
|
||||
if result.console_messages:
|
||||
# Count messages by type
|
||||
message_types = {}
|
||||
for msg in result.console_messages:
|
||||
msg_type = msg.get("type", "unknown")
|
||||
message_types[msg_type] = message_types.get(msg_type, 0) + 1
|
||||
|
||||
print(f"Message type counts: {message_types}")
|
||||
|
||||
# Display errors (which are usually most important)
|
||||
for msg in result.console_messages:
|
||||
if msg.get("type") == "error":
|
||||
print(f"Error: {msg.get('text')}")
|
||||
```
|
||||
|
||||
These fields provide deep visibility into the page's network activity and browser console, which is invaluable for debugging, security analysis, and understanding complex web applications.
|
||||
|
||||
For more details on network and console capturing, see the [Network & Console Capture documentation](../advanced/network-console-capture.md).

# Crawl4AI 0.6.0
|
||||
|
||||
*Release date: 2025‑04‑22*
|
||||
|
||||
0.6.0 is the **biggest jump** since the 0.5 series, packing a smarter browser core, pool‑based crawlers, and a ton of DX candy. Expect faster runs, lower RAM burn, and richer diagnostics.
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Key upgrades
|
||||
|
||||
| Area | What changed |
|
||||
|------|--------------|
|
||||
| **Browser** | New **Browser** management with pooling, page pre‑warm, geolocation + locale + timezone switches |
|
||||
| **Crawler** | Console and network log capture, MHTML snapshots, safer `get_page` API |
|
||||
| **Server & API** | **Crawler Pool Manager** endpoint, MCP socket + SSE support |
|
||||
| **Docs** | v2 layout, floating Ask‑AI helper, GitHub stats badge, copy‑code buttons, Docker API demo |
|
||||
| **Tests** | Memory + load benchmarks, 90+ new cases covering MCP and Docker |
|
||||
|
||||
---
|
||||
|
||||
## ⚠️ Breaking changes
|
||||
|
||||
1. **`get_page` signature** – returns `(html, metadata)` instead of plain html.
|
||||
2. **Docker** – new Chromium base layer, rebuild images.
|
||||
|
||||
---
|
||||
|
||||
## How to upgrade
|
||||
|
||||
```bash
|
||||
pip install -U crawl4ai==0.6.0
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Full changelog
|
||||
|
||||
The diff between `main` and `next` spans **36 k insertions, 4.9 k deletions** over 121 files. Read the [compare view](https://github.com/unclecode/crawl4ai/compare/0.5.0.post8...0.6.0) or see `CHANGELOG.md` for the granular list.
|
||||
|
||||
---
|
||||
|
||||
## Upgrade tips
|
||||
|
||||
* Using the Docker API? Pull `unclecode/crawl4ai:0.6.0`, new args are documented in `/deploy/docker/README.md`.
|
||||
* Stress‑test your stack with `tests/memory/run_benchmark.py` before production rollout.
|
||||
* Markdown generators renamed but aliased, update when convenient, warnings will remind you.

In most examples, you create **one** `BrowserConfig` for the entire crawler session, then pass a **fresh** or re-used `CrawlerRunConfig` whenever you call `arun()`. This tutorial shows the most commonly used parameters. If you need advanced or rarely used fields, see the [Configuration Parameters](../api/parameters.md).

## 1. CSS-Based Selection
|

|

There are two ways to select content from a page: using `css_selector` or the more flexible `target_elements`.
|
||||
|
||||
### 1.1 Using `css_selector`
|
||||
|
||||

|

|
||||
### 1.2 Using `target_elements`
|
||||
|
||||
The `target_elements` parameter provides more flexibility by allowing you to target **multiple elements** for content extraction while preserving the entire page context for other features:
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
|
||||
async def main():
|
||||
config = CrawlerRunConfig(
|
||||
# Target article body and sidebar, but not other content
|
||||
target_elements=["article.main-content", "aside.sidebar"]
|
||||
)

||||

if __name__ == "__main__":

||||

|
||||
```
|
||||
|
||||
**Key difference**: With `target_elements`, the markdown generation and structural data extraction focus on those elements, but other page elements (like links, images, and tables) are still extracted from the entire page. This gives you fine-grained control over what appears in your markdown content while preserving full page context for link analysis and media collection.

## 7. Combining CSS Selection Methods
|
||||
|
||||
By mixing **css_selector** scoping, **content filtering** parameters, and advanced **extraction strategies**, you can precisely **choose** which data to keep. Key parameters in **`CrawlerRunConfig`** for content selection include:
|
||||
You can combine `css_selector` and `target_elements` in powerful ways to achieve fine-grained control over your output:
|
||||
|
||||
1. **`css_selector`** – Basic scoping to an element or region.
|
||||
2. **`word_count_threshold`** – Skip short blocks.
|
||||
3. **`excluded_tags`** – Remove entire HTML tags.
|
||||
4. **`exclude_external_links`**, **`exclude_social_media_links`**, **`exclude_domains`** – Filter out unwanted links or domains.
|
||||
5. **`exclude_external_images`** – Remove images from external sources.
|
||||
6. **`process_iframes`** – Merge iframe content if needed.
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, CacheMode
|
||||
|
||||
async def main():
|
||||
# Target specific content but preserve page context
|
||||
config = CrawlerRunConfig(
|
||||
# Focus markdown on main content and sidebar
|
||||
target_elements=["#main-content", ".sidebar"],
|
||||

||||

|
||||

|
||||

||||
# Use basic content thresholds
|
||||

|
||||

|
||||

|
||||
)
|
||||
|
||||
print(f"Content focuses on specific elements, but all links still analyzed")
|
||||
print(f"Internal links: {len(result.links.get('internal', []))}")
|

|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
This approach gives you the best of both worlds:
|
||||
- Markdown generation and content extraction focus on the elements you care about
|
||||
- Links, images and other page data still give you the full context of the page
|
||||
- Content filtering still applies globally
|
||||
|
||||
## 8. Conclusion
|
||||
|
||||
By mixing **target_elements** or **css_selector** scoping, **content filtering** parameters, and advanced **extraction strategies**, you can precisely **choose** which data to keep. Key parameters in **`CrawlerRunConfig`** for content selection include:
|
||||
|
||||
1. **`target_elements`** – Array of CSS selectors to focus markdown generation and data extraction, while preserving full page context for links and media.
|
||||
2. **`css_selector`** – Basic scoping to an element or region for all extraction processes.
|
||||
3. **`word_count_threshold`** – Skip short blocks.
|
||||
4. **`excluded_tags`** – Remove entire HTML tags.
|
||||
5. **`exclude_external_links`**, **`exclude_social_media_links`**, **`exclude_domains`** – Filter out unwanted links or domains.
|
||||
6. **`exclude_external_images`** – Remove images from external sources.
|
||||
7. **`process_iframes`** – Merge iframe content if needed.
|
||||
|
||||
Combine these with structured extraction (CSS, LLM-based, or others) to build powerful crawls that yield exactly the content you want, from raw or cleaned HTML up to sophisticated JSON structures. For more detail, see [Configuration Reference](../api/parameters.md). Enjoy curating your data to the max!

|
||||
|
||||
#### Excluding External Images
|
||||
|
||||
If you're dealing with heavy pages or want to skip third-party images (advertisements, for example), you can turn on:
|
||||
|
||||
```python
|
||||
crawler_cfg = CrawlerRunConfig(
|
||||
exclude_external_images=True
|
||||
)
|
||||
```
|
||||
|
||||
This setting attempts to discard images from outside the primary domain, keeping only those from the site you're crawling.
|
||||
|
||||
#### Excluding All Images
|
||||
|
||||
If you want to completely remove all images from the page to maximize performance and reduce memory usage, use:
|
||||
|
||||
```python
|
||||
crawler_cfg = CrawlerRunConfig(
|
||||
exclude_all_images=True
|
||||
)
|
||||
```
|
||||
|
||||
This setting removes all images very early in the processing pipeline, which significantly improves memory efficiency and processing speed. This is particularly useful when:
|
||||
- You don't need image data in your results
|
||||
- You're crawling image-heavy pages that cause memory issues
|

- You want to focus only on text content

### 3.3 Additional Media Config
|
||||
### 3.3 Working with Tables
|
||||
|
||||
Crawl4AI can detect and extract structured data from HTML tables. Tables are analyzed based on various criteria to determine if they are actual data tables (as opposed to layout tables), including:
|
||||
|
||||
- Presence of thead and tbody sections
|
||||
- Use of th elements for headers
|
||||
- Column consistency
|
||||
- Text density
|
||||
- And other factors
|
||||
|
||||
Tables that score above the threshold (default: 7) are extracted and stored in `result.media.tables`.
|
||||
|
||||
**Accessing Table Data**:
|
||||
|
||||
```python
|
||||
if result.success:
|
||||
tables = result.media.get("tables", [])
|
||||
print(f"Found {len(tables)} data tables on the page")
|
||||
|
||||
if tables:
|
||||
# Access the first table
|
||||
first_table = tables[0]
|
||||
print(f"Table caption: {first_table.get('caption', 'No caption')}")
|
||||
print(f"Headers: {first_table.get('headers', [])}")
|
||||
|
||||
# Print the first 3 rows
|
||||
for i, row in enumerate(first_table.get('rows', [])[:3]):
|
||||
print(f"Row {i+1}: {row}")
|
||||
```
|
||||
|
||||
**Configuring Table Extraction**:
|
||||
|
||||
You can adjust the sensitivity of the table detection algorithm with:
|
||||
|
||||
```python
|
||||
crawler_cfg = CrawlerRunConfig(
|
||||
table_score_threshold=5 # Lower value = more tables detected (default: 7)
|
||||
)
|
||||
```
|
||||
|
||||
Each extracted table contains:
|
||||
- `headers`: Column header names
|
||||
- `rows`: List of rows, each containing cell values
|
||||
- `caption`: Table caption text (if available)
|
||||
- `summary`: Table summary attribute (if specified)
|
||||
|
||||
### 3.4 Additional Media Config
|
||||
|
||||
- **`screenshot`**: Set to `True` if you want a full-page screenshot stored as `base64` in `result.screenshot`.
|
||||
- **`pdf`**: Set to `True` if you want a PDF version of the page in `result.pdf`.
|
||||
- **`capture_mhtml`**: Set to `True` if you want an MHTML snapshot of the page in `result.mhtml`. This format preserves the entire web page with all its resources (CSS, images, scripts) in a single file, making it perfect for archiving or offline viewing.
|
||||
- **`wait_for_images`**: If `True`, attempts to wait until images are fully loaded before final extraction.
|
||||
|
||||
#### Example: Capturing Page as MHTML
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
|
||||
async def main():
|
||||
crawler_cfg = CrawlerRunConfig(
|
||||
capture_mhtml=True # Enable MHTML capture
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun("https://example.com", config=crawler_cfg)
|
||||
|
||||
if result.success and result.mhtml:
|
||||
# Save the MHTML snapshot to a file
|
||||
with open("example.mhtml", "w", encoding="utf-8") as f:
|
||||
f.write(result.mhtml)
|
||||
print("MHTML snapshot saved to example.mhtml")
|
||||
else:
|
||||
print("Failed to capture MHTML:", result.error_message)
|
||||
|
||||
if __name__ == "__main__":
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
The MHTML format is particularly useful because:
|
||||
- It captures the complete page state including all resources
|
||||
- It can be opened in most modern browsers for offline viewing
|
||||
- It preserves the page exactly as it appeared during crawling
|
||||
- It's a single file, making it easy to store and transfer

### Table Extraction Tips
|
||||
|
||||
- Not all HTML tables are extracted - only those detected as "data tables" vs. layout tables.
|
||||
- Tables with inconsistent cell counts, nested tables, or those used purely for layout may be skipped.
|
||||
- If you're missing tables, try adjusting the `table_score_threshold` to a lower value (default is 7).
|
||||
|
||||
The table detection algorithm scores tables based on features like consistent columns, presence of headers, text density, and more. Tables scoring above the threshold are considered data tables worth extracting.

## 4. Selecting the HTML Source for Markdown Generation
|
||||
|
||||
The `content_source` parameter allows you to control which HTML content is used as input for markdown generation. This gives you flexibility in how the HTML is processed before conversion to markdown.
|
||||
|
||||
```python
|
||||
from crawl4ai.markdown_generation_strategy import DefaultMarkdownGenerator
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
|
||||
async def main():
|
||||
# Option 1: Use the raw HTML directly from the webpage (before any processing)
|
||||
raw_md_generator = DefaultMarkdownGenerator(
|
||||
content_source="raw_html",
|
||||
options={"ignore_links": True}
|
||||
)
|
||||
|
||||
# Option 2: Use the cleaned HTML (after scraping strategy processing - default)
|
||||
cleaned_md_generator = DefaultMarkdownGenerator(
|
||||
content_source="cleaned_html", # This is the default
|
||||
options={"ignore_links": True}
|
||||
)
|
||||
|
||||
# Option 3: Use preprocessed HTML optimized for schema extraction
|
||||
fit_md_generator = DefaultMarkdownGenerator(
|
||||
content_source="fit_html",
|
||||
options={"ignore_links": True}
|
||||
)
|
||||
|
||||
# Use one of the generators in your crawler config
|
||||
config = CrawlerRunConfig(
|
||||
markdown_generator=raw_md_generator # Try each of the generators
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun("https://example.com", config=config)
|
||||
if result.success:
|
||||
print("Markdown:\n", result.markdown.raw_markdown[:500])
|
||||
else:
|
||||
print("Crawl failed:", result.error_message)
|
||||
|
||||
if __name__ == "__main__":
|
||||
import asyncio
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
### HTML Source Options
|
||||
|
||||
- **`"cleaned_html"`** (default): Uses the HTML after it has been processed by the scraping strategy. This HTML is typically cleaner and more focused on content, with some boilerplate removed.
|
||||
|
||||
- **`"raw_html"`**: Uses the original HTML directly from the webpage, before any cleaning or processing. This preserves more of the original content, but may include navigation bars, ads, footers, and other elements that might not be relevant to the main content.
|
||||
|
||||
- **`"fit_html"`**: Uses HTML preprocessed for schema extraction. This HTML is optimized for structured data extraction and may have certain elements simplified or removed.
|
||||
|
||||
### When to Use Each Option
|
||||
|
||||
- Use **`"cleaned_html"`** (default) for most cases where you want a balance of content preservation and noise removal.
|
||||
- Use **`"raw_html"`** when you need to preserve all original content, or when the cleaning process is removing content you actually want to keep.
|
||||
- Use **`"fit_html"`** when working with structured data or when you need HTML that's optimized for schema extraction.
