### Asynchronous Jobs with Webhooks
|
||||
|
||||
For long-running crawls or when you want to avoid keeping connections open, use the job queue endpoints. Instead of polling for results, configure a webhook to receive notifications when jobs complete.
|
||||
|
||||
#### Why Use Jobs & Webhooks?
|
||||
|
||||
- **No Polling Required** - Get notified when crawls complete instead of constantly checking status
|
||||
- **Better Resource Usage** - Free up client connections while jobs run in the background
|
||||
- **Scalable Architecture** - Ideal for high-volume crawling with TypeScript/Node.js clients or microservices
|
||||
- **Reliable Delivery** - Automatic retry with exponential backoff (5 attempts: 1s → 2s → 4s → 8s → 16s)
|
||||
|
||||
#### How It Works
|
||||
|
||||
1. **Submit Job** → POST to `/crawl/job` with optional `webhook_config`
|
||||
2. **Get Task ID** → Receive a `task_id` immediately
|
||||
3. **Job Runs** → Crawl executes in the background
|
||||
4. **Webhook Fired** → Server POSTs completion notification to your webhook URL
|
||||
5. **Fetch Results** → If data wasn't included in webhook, GET `/crawl/job/{task_id}`
|
||||
|
||||
#### Quick Example
|
||||
|
||||
```bash
|
||||
# Submit a crawl job with webhook notification
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": false
|
||||
}
|
||||
}'
|
||||
|
||||
# Response: {"task_id": "crawl_a1b2c3d4"}
|
||||
```
|
||||
|
||||
**Your webhook receives:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4",
|
||||
"task_type": "crawl",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"]
|
||||
}
|
||||
```
|
||||
|
||||
Then fetch the results:
|
||||
```bash
|
||||
curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
|
||||
```
|
||||
|
||||
#### Include Data in Webhook
|
||||
|
||||
Set `webhook_data_in_payload: true` to receive the full crawl results directly in the webhook:
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": true
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
**Your webhook receives the complete data:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4",
|
||||
"task_type": "crawl",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"],
|
||||
"data": {
|
||||
"markdown": "...",
|
||||
"html": "...",
|
||||
"links": {...},
|
||||
"metadata": {...}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Webhook Authentication
|
||||
|
||||
Add custom headers for authentication:
|
||||
|
||||
```json
|
||||
{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl",
|
||||
"webhook_data_in_payload": false,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token",
|
||||
"X-Service-ID": "crawl4ai-prod"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Global Default Webhook
|
||||
|
||||
Configure a default webhook URL in `config.yml` for all jobs:
|
||||
|
||||
```yaml
|
||||
webhooks:
|
||||
enabled: true
|
||||
default_url: "https://myapp.com/webhooks/default"
|
||||
data_in_payload: false
|
||||
retry:
|
||||
max_attempts: 5
|
||||
initial_delay_ms: 1000
|
||||
max_delay_ms: 32000
|
||||
timeout_ms: 30000
|
||||
```
|
||||
|
||||
Now jobs without `webhook_config` automatically use the default webhook.
|
||||
|
||||
#### Job Status Polling (Without Webhooks)
|
||||
|
||||
If you prefer polling instead of webhooks, just omit `webhook_config`:
|
||||
|
||||
```bash
|
||||
# Submit job
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"urls": ["https://example.com"]}'
|
||||
# Response: {"task_id": "crawl_xyz"}
|
||||
|
||||
# Poll for status
|
||||
curl http://localhost:11235/crawl/job/crawl_xyz
|
||||
```
|
||||
|
||||
The response includes `status` field: `"processing"`, `"completed"`, or `"failed"`.
|
||||
|
||||
> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

||||
```
|
||||
|
||||
## API Usage Examples
|
||||
|
||||
### Example 1: Basic Webhook (Notification Only)
|
||||
|
||||
Send a webhook notification without including the crawl data in the payload.
|
||||
|
||||
**Request:**
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": false
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4"
|
||||
}
|
||||
```
|
||||
|
||||
**Webhook Payload Received:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4",
|
||||
"task_type": "crawl",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"]
|
||||
}
|
||||
```
|
||||
|
||||
Your webhook handler should then fetch the results:
|
||||
```bash
|
||||
curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
|
||||
```
|
||||
|
||||
### Example 2: Webhook with Data Included
|
||||
|
||||
Include the full crawl results in the webhook payload.
|
||||
|
||||
**Request:**
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": true
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
**Webhook Payload Received:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4",
|
||||
"task_type": "crawl",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"],
|
||||
"data": {
|
||||
"markdown": "...",
|
||||
"html": "...",
|
||||
"links": {...},
|
||||
"metadata": {...}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Webhook with Custom Headers
|
||||
|
||||
Include custom headers for authentication or identification.
|
||||
|
||||
**Request:**
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": false,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "my-secret-token",
|
||||
"X-Service-ID": "crawl4ai-production"
|
||||
}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
The webhook will be sent with these additional headers plus the default headers from config.
|
||||
|
||||
### Example 4: Failure Notification
|
||||
|
||||
When a crawl job fails, a webhook is sent with error details.
|
||||
|
||||
**Webhook Payload on Failure:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_a1b2c3d4",
|
||||
"task_type": "crawl",
|
||||
"status": "failed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"],
|
||||
"error": "Connection timeout after 30s"
|
||||
}
|
||||
```
|
||||
|
||||
### Example 5: Using Global Default Webhook
|
||||
|
||||
If you set a `default_url` in config.yml, jobs without webhook_config will use it:
|
||||
|
||||
**config.yml:**
|
||||
```yaml
|
||||
webhooks:
|
||||
enabled: true
|
||||
default_url: "https://myapp.com/webhooks/default"
|
||||
data_in_payload: false
|
||||
```
|
||||
|
||||
**Request (no webhook_config needed):**
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"]
|
||||
}'
|
||||
```
|
||||
|
||||
The webhook will be sent to the default URL configured in config.yml.
|
||||
|
||||
### Example 6: LLM Extraction Job with Webhook
|
||||
|
||||
Use webhooks with the LLM extraction endpoint for asynchronous processing.
|
||||
|
||||
**Request:**
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/llm/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"url": "https://example.com/article",
|
||||
"q": "Extract the article title, author, and publication date",
|
||||
"schema": "{\"type\": \"object\", \"properties\": {\"title\": {\"type\": \"string\"}, \"author\": {\"type\": \"string\"}, \"date\": {\"type\": \"string\"}}}",
|
||||
"cache": false,
|
||||
"provider": "openai/gpt-4o-mini",
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/llm-complete",
|
||||
"webhook_data_in_payload": true
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"task_id": "llm_1698765432_12345"
|
||||
}
|
||||
```
|
||||
|
||||
**Webhook Payload Received:**
|
||||
```json
|
||||
{
|
||||
"task_id": "llm_1698765432_12345",
|
||||
"task_type": "llm_extraction",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-21T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com/article"],
|
||||
"data": {
|
||||
"extracted_content": {
|
||||
"title": "Understanding Web Scraping",
|
||||
"author": "John Doe",
|
||||
"date": "2025-10-21"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Webhook Handler Example
|
||||
|
||||
Here's a simple Python Flask webhook handler that supports both crawl and LLM extraction jobs:
|
||||
|
||||
```python
|
||||
from flask import Flask, request, jsonify
|
||||
import requests
|
||||
|
||||
app = Flask(__name__)
|
||||
|
||||
@app.route('/webhooks/crawl-complete', methods=['POST'])
|
||||
def handle_crawl_webhook():
|
||||
payload = request.json
|
||||
|
||||
task_id = payload['task_id']
|
||||
task_type = payload['task_type']
|
||||
status = payload['status']
|
||||
|
||||
if status == 'completed':
|
||||
# If data not in payload, fetch it
|
||||
if 'data' not in payload:
|
||||
# Determine endpoint based on task type
|
||||
endpoint = 'crawl' if task_type == 'crawl' else 'llm'
|
||||
response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
|
||||
data = response.json()
|
||||
else:
|
||||
data = payload['data']
|
||||
|
||||
# Process based on task type
|
||||
if task_type == 'crawl':
|
||||
print(f"Processing crawl results for {task_id}")
|
||||
# Handle crawl results
|
||||
results = data.get('results', [])
|
||||
for result in results:
|
||||
print(f" - {result.get('url')}: {len(result.get('markdown', ''))} chars")
|
||||
|
||||
elif task_type == 'llm_extraction':
|
||||
print(f"Processing LLM extraction for {task_id}")
|
||||
# Handle LLM extraction
|
||||
# Note: Webhook sends 'extracted_content', API returns 'result'
|
||||
extracted = data.get('extracted_content', data.get('result', {}))
|
||||
print(f" - Extracted: {extracted}")
|
||||
|
||||
# Your business logic here...
|
||||
|
||||
elif status == 'failed':
|
||||
error = payload.get('error', 'Unknown error')
|
||||
print(f"{task_type} job {task_id} failed: {error}")
|
||||
# Handle failure...
|
||||
|
||||
return jsonify({"status": "received"}), 200
|
||||
|
||||
if __name__ == '__main__':
|
||||
app.run(port=8080)
|
||||
```
|
||||
|
||||
## Retry Logic
|
||||
|
||||
The webhook delivery service uses exponential backoff retry logic:
|
||||
|
||||
- **Attempts:** Up to 5 attempts by default
|
||||
- **Delays:** 1s → 2s → 4s → 8s → 16s
|
||||
- **Timeout:** 30 seconds per attempt
|
||||
- **Retry Conditions:**
|
||||
- Server errors (5xx status codes)
|
||||
- Network errors
|
||||
- Timeouts
|
||||
- **No Retry:**
|
||||
- Client errors (4xx status codes)
|
||||
- Successful delivery (2xx status codes)
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **No Polling Required** - Eliminates constant API calls to check job status
|
||||
2. **Real-time Notifications** - Immediate notification when jobs complete
|
||||
3. **Reliable Delivery** - Exponential backoff ensures webhooks are delivered
|
||||
4. **Flexible** - Choose between notification-only or full data delivery
|
||||
5. **Secure** - Support for custom headers for authentication
|
||||
6. **Configurable** - Global defaults or per-job configuration
|
||||
7. **Universal Support** - Works with both `/crawl/job` and `/llm/job` endpoints

## Monitoring and Debugging
|
||||
|
||||
Webhook delivery attempts are logged at INFO level:
|
||||
- Successful deliveries
|
||||
- Retry attempts with delays
|
||||
- Final failures after max attempts
|
||||
|
||||
Check the application logs for webhook delivery status:
|
||||
```bash
|
||||
docker logs crawl4ai-container | grep -i webhook
|
||||
```

- **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

```
|
||||
|
||||
**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

# 🚀 Crawl4AI v0.7.5: The Docker Hooks & Security Update
|
||||
|
||||
*September 29, 2025 • 8 min read*
|
||||
|
||||
---
|
||||
|
||||
Today I'm releasing Crawl4AI v0.7.5—focused on extensibility and security. This update introduces the Docker Hooks System for pipeline customization, enhanced LLM integration, and important security improvements.
|
||||
|
||||
## 🎯 What's New at a Glance
|
||||
|
||||
- **Docker Hooks System**: Custom Python functions at key pipeline points with function-based API
|
||||
- **Function-Based Hooks**: New `hooks_to_string()` utility with Docker client auto-conversion
|
||||
- **Enhanced LLM Integration**: Custom providers with temperature control
|
||||
- **HTTPS Preservation**: Secure internal link handling
|
||||
- **Bug Fixes**: Resolved multiple community-reported issues
|
||||
- **Improved Docker Error Handling**: Better debugging and reliability
|
||||
|
||||
## 🔧 Docker Hooks System: Pipeline Customization
|
||||
|
||||
Every scraping project needs custom logic—authentication, performance optimization, content processing. Traditional solutions require forking or complex workarounds. Docker Hooks let you inject custom Python functions at 8 key points in the crawling pipeline.
|
||||
|
||||
### Real Example: Authentication & Performance
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
# Real working hooks for httpbin.org
|
||||
hooks_config = {
|
||||
"on_page_context_created": """
|
||||
async def hook(page, context, **kwargs):
|
||||
print("Hook: Setting up page context")
|
||||
# Block images to speed up crawling
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
print("Hook: Images blocked")
|
||||
return page
|
||||
""",
|
||||
|
||||

|
||||
async def hook(page, context, **kwargs):

||||
# Scroll to bottom to load lazy content
|
||||
await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
|
||||
await page.wait_for_timeout(1000)
|
||||
print("Hook: Scrolled to bottom")
|
||||
return page
|
||||
""",
|
||||
|
||||
"before_goto": """
|
||||
async def hook(page, context, url, **kwargs):

||||

|
||||
# Add custom headers
|
||||
await page.set_extra_http_headers({
|
||||
'X-Test-Header': 'crawl4ai-hooks-test'
|
||||
})
|
||||
return page
|
||||
"""
|
||||
}
|
||||
|
||||
# Test with Docker API
|
||||
payload = {
|
||||
"urls": ["https://httpbin.org/html"],
|
||||
"hooks": {
|
||||
"code": hooks_config,
|
||||
"timeout": 30
|
||||
}
|
||||
}
|
||||
|
||||
response = requests.post("http://localhost:11235/crawl", json=payload)
|
||||
result = response.json()
|
||||
|
||||
if result.get('success'):
|
||||
print("✅ Hooks executed successfully!")
|
||||
print(f"Content length: {len(result.get('markdown', ''))} characters")
|
||||
```
|
||||
|
||||
**Available Hook Points:**
|
||||
- `on_browser_created`: Browser setup
|
||||
- `on_page_context_created`: Page context configuration
|
||||
- `before_goto`: Pre-navigation setup
|
||||
- `after_goto`: Post-navigation processing
|
||||
- `on_user_agent_updated`: User agent changes
|
||||
- `on_execution_started`: Crawl initialization
|
||||
- `before_retrieve_html`: Pre-extraction processing
|
||||
- `before_return_html`: Final HTML processing
|
||||
|
||||
### Function-Based Hooks API
|
||||
|
||||
Writing hooks as strings works, but lacks IDE support and type checking. v0.7.5 introduces a function-based approach with automatic conversion!
|
||||
|
||||
**Option 1: Using the `hooks_to_string()` Utility**
|
||||
|
||||
```python
|
||||
from crawl4ai import hooks_to_string
|
||||
import requests
|
||||
|
||||
# Define hooks as regular Python functions (with full IDE support!)
|
||||
async def on_page_context_created(page, context, **kwargs):
|
||||
"""Block images to speed up crawling"""
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
await page.set_viewport_size({"width": 1920, "height": 1080})
|
||||
return page
|
||||
|
||||
async def before_goto(page, context, url, **kwargs):
|
||||
"""Add custom headers"""
|
||||
await page.set_extra_http_headers({
|
||||
'X-Crawl4AI': 'v0.7.5',
|
||||
'X-Custom-Header': 'my-value'
|
||||
})
|
||||
return page
|
||||
|
||||
# Convert functions to strings
|
||||
hooks_code = hooks_to_string({
|
||||
"on_page_context_created": on_page_context_created,
|
||||
"before_goto": before_goto
|
||||
})
|
||||
|
||||
# Use with REST API
|
||||
payload = {
|
||||
"urls": ["https://httpbin.org/html"],
|
||||
"hooks": {"code": hooks_code, "timeout": 30}
|
||||
}
|
||||
response = requests.post("http://localhost:11235/crawl", json=payload)
|
||||
```
|
||||
|
||||
**Option 2: Docker Client with Automatic Conversion (Recommended!)**
|
||||
|
||||
```python
|
||||
from crawl4ai.docker_client import Crawl4aiDockerClient
|
||||
|
||||
# Define hooks as functions (same as above)
|
||||
async def on_page_context_created(page, context, **kwargs):
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
return page
|
||||
|
||||
async def before_retrieve_html(page, context, **kwargs):
|
||||
# Scroll to load lazy content
|
||||
await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
|
||||
await page.wait_for_timeout(1000)
|
||||
return page
|
||||
|
||||
# Use Docker client - conversion happens automatically!
|
||||
client = Crawl4aiDockerClient(base_url="http://localhost:11235")
|
||||
|
||||
results = await client.crawl(
|
||||
urls=["https://httpbin.org/html"],
|
||||
hooks={
|
||||
"on_page_context_created": on_page_context_created,
|
||||
"before_retrieve_html": before_retrieve_html
|
||||
},
|
||||
hooks_timeout=30
|
||||
)
|
||||
|
||||
if results and results.success:
|
||||
print(f"✅ Hooks executed! HTML length: {len(results.html)}")
|
||||
```
|
||||
|
||||
**Benefits of Function-Based Hooks:**
|
||||
- ✅ Full IDE support (autocomplete, syntax highlighting)
|
||||
- ✅ Type checking and linting
|
||||
- ✅ Easier to test and debug
|
||||
- ✅ Reusable across projects
|
||||
- ✅ Automatic conversion in Docker client
|
||||
- ✅ No breaking changes - string hooks still work!
|
||||
|
||||
## 🤖 Enhanced LLM Integration
|
||||
|
||||
Enhanced LLM integration with custom providers, temperature control, and base URL configuration.
|
||||
|
||||
### Multi-Provider Support
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
from crawl4ai.extraction_strategy import LLMExtractionStrategy
|
||||
|
||||
# Test with different providers
|
||||
async def test_llm_providers():
|
||||
# OpenAI with custom temperature
|
||||
openai_strategy = LLMExtractionStrategy(
|
||||
provider="gemini/gemini-2.5-flash-lite",
|
||||
api_token="your-api-token",
|
||||
temperature=0.7, # New in v0.7.5
|
||||
instruction="Summarize this page in one sentence"
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
"https://example.com",
|
||||
config=CrawlerRunConfig(extraction_strategy=openai_strategy)
|
||||
)
|
||||
|
||||
if result.success:
|
||||
print("✅ LLM extraction completed")
|
||||
print(result.extracted_content)
|
||||
|
||||
# Docker API with enhanced LLM config
|
||||
llm_payload = {
|
||||
"url": "https://example.com",
|
||||
"f": "llm",
|
||||
"q": "Summarize this page in one sentence.",
|
||||
"provider": "gemini/gemini-2.5-flash-lite",
|
||||
"temperature": 0.7
|
||||
}
|
||||
|
||||
response = requests.post("http://localhost:11235/md", json=llm_payload)
|
||||
```
|
||||
|
||||
**New Features:**
|
||||
- Custom `temperature` parameter for creativity control
|
||||
- `base_url` for custom API endpoints
|
||||
- Multi-provider environment variable support
|
||||
- Docker API integration
|
||||
|
||||
## 🔒 HTTPS Preservation
|
||||
|
||||
**The Problem:** Modern web apps require HTTPS everywhere. When crawlers downgrade internal links from HTTPS to HTTP, authentication breaks and security warnings appear.
|
||||
|
||||
**Solution:** HTTPS preservation maintains secure protocols throughout crawling.
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, FilterChain, URLPatternFilter, BFSDeepCrawlStrategy
|
||||
|
||||
async def test_https_preservation():
|
||||
# Enable HTTPS preservation
|
||||
url_filter = URLPatternFilter(
|
||||
patterns=["^(https:\/\/)?quotes\.toscrape\.com(\/.*)?$"]
|
||||
)
|
||||
|
||||
config = CrawlerRunConfig(
|
||||
exclude_external_links=True,
|
||||
preserve_https_for_internal_links=True, # New in v0.7.5
|
||||
deep_crawl_strategy=BFSDeepCrawlStrategy(
|
||||
max_depth=2,
|
||||
max_pages=5,
|
||||
filter_chain=FilterChain([url_filter])
|
||||
)
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
async for result in await crawler.arun(
|
||||
url="https://quotes.toscrape.com",
|
||||
config=config
|
||||
):
|
||||
# All internal links maintain HTTPS
|
||||
internal_links = [link['href'] for link in result.links['internal']]
|
||||
https_links = [link for link in internal_links if link.startswith('https://')]
|
||||
|
||||
print(f"HTTPS links preserved: {len(https_links)}/{len(internal_links)}")
|
||||
for link in https_links[:3]:
|
||||
print(f" → {link}")
|
||||
```
|
||||
|
||||

# Crawl4AI v0.7.6 Release Notes
|
||||
|
||||
*Release Date: October 22, 2025*
|
||||
|
||||
I'm excited to announce Crawl4AI v0.7.6, featuring a complete webhook infrastructure for the Docker job queue API! This release eliminates polling and brings real-time notifications to both crawling and LLM extraction workflows.
|
||||
|
||||
## 🎯 What's New
|
||||
|
||||
### Webhook Support for Docker Job Queue API
|
||||
|
||||
The headline feature of v0.7.6 is comprehensive webhook support for asynchronous job processing. No more constant polling to check if your jobs are done - get instant notifications when they complete!
|
||||
|
||||
**Key Capabilities:**
|
||||
|
||||
- ✅ **Universal Webhook Support**: Both `/crawl/job` and `/llm/job` endpoints now support webhooks
|
||||
- ✅ **Flexible Delivery Modes**: Choose notification-only or include full data in the webhook payload
|
||||
- ✅ **Reliable Delivery**: Exponential backoff retry mechanism (5 attempts: 1s → 2s → 4s → 8s → 16s)
|
||||
- ✅ **Custom Authentication**: Add custom headers for webhook authentication
|
||||
- ✅ **Global Configuration**: Set default webhook URL in `config.yml` for all jobs
|
||||
- ✅ **Task Type Identification**: Distinguish between `crawl` and `llm_extraction` tasks
|
||||
|
||||
### How It Works
|
||||
|
||||
Instead of constantly checking job status:
|
||||
|
||||
**OLD WAY (Polling):**
|
||||
```python
|
||||
# Submit job
|
||||
response = requests.post("http://localhost:11235/crawl/job", json=payload)
|
||||
task_id = response.json()['task_id']
|
||||
|
||||
# Poll until complete
|
||||
while True:
|
||||
status = requests.get(f"http://localhost:11235/crawl/job/{task_id}")
|
||||
if status.json()['status'] == 'completed':
|
||||
break
|
||||
time.sleep(5) # Wait and try again
|
||||
```
|
||||
|
||||
**NEW WAY (Webhooks):**
|
||||
```python
|
||||
# Submit job with webhook
|
||||
payload = {
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhook",
|
||||
"webhook_data_in_payload": True
|
||||
}
|
||||
}
|
||||
response = requests.post("http://localhost:11235/crawl/job", json=payload)
|
||||
|
||||
# Done! Webhook will notify you when complete
|
||||
# Your webhook handler receives the results automatically
|
||||
```
|
||||
|
||||
### Crawl Job Webhooks
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"browser_config": {"headless": true},
|
||||
"crawler_config": {"cache_mode": "bypass"},
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": false,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
### LLM Extraction Job Webhooks (NEW!)
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/llm/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"url": "https://example.com/article",
|
||||
"q": "Extract the article title, author, and publication date",
|
||||
"schema": "{\"type\":\"object\",\"properties\":{\"title\":{\"type\":\"string\"}}}",
|
||||
"provider": "openai/gpt-4o-mini",
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/llm-complete",
|
||||
"webhook_data_in_payload": true
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
### Webhook Payload Structure
|
||||
|
||||
**Success (with data):**
|
||||
```json
|
||||
{
|
||||
"task_id": "llm_1698765432",
|
||||
"task_type": "llm_extraction",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-22T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com/article"],
|
||||
"data": {
|
||||
"extracted_content": {
|
||||
"title": "Understanding Web Scraping",
|
||||
"author": "John Doe",
|
||||
"date": "2025-10-22"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Failure:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_abc123",
|
||||
"task_type": "crawl",
|
||||
"status": "failed",
|
||||
"timestamp": "2025-10-22T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"],
|
||||
"error": "Connection timeout after 30s"
|
||||
}
|
||||
```
|
||||
|
||||
### Simple Webhook Handler Example
|
||||
|
||||
```python
|
||||
from flask import Flask, request, jsonify
|
||||
|
||||
app = Flask(__name__)
|
||||
|
||||
@app.route('/webhook', methods=['POST'])
|
||||
def handle_webhook():
|
||||
payload = request.json
|
||||
|
||||
task_id = payload['task_id']
|
||||
task_type = payload['task_type']
|
||||
status = payload['status']
|
||||
|
||||
if status == 'completed':
|
||||
if 'data' in payload:
|
||||
# Process data directly
|
||||
data = payload['data']
|
||||
else:
|
||||
# Fetch from API
|
||||
endpoint = 'crawl' if task_type == 'crawl' else 'llm'
|
||||
response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
|
||||
data = response.json()
|
||||
|
||||
# Your business logic here
|
||||
print(f"Job {task_id} completed!")
|
||||
|
||||
elif status == 'failed':
|
||||
error = payload.get('error', 'Unknown error')
|
||||
print(f"Job {task_id} failed: {error}")
|
||||
|
||||
return jsonify({"status": "received"}), 200
|
||||
|
||||
app.run(port=8080)
|
||||
```
|
||||
|
||||
## 📊 Performance Improvements
|
||||
|
||||
- **Reduced Server Load**: Eliminates constant polling requests
|
||||
- **Lower Latency**: Instant notification vs. polling interval delay
|
||||
- **Better Resource Usage**: Frees up client connections while jobs run in background
|
||||
- **Scalable Architecture**: Handles high-volume crawling workflows efficiently
|
||||
|
||||
## 🐛 Bug Fixes
|
||||
|
||||
- Fixed webhook configuration serialization for Pydantic HttpUrl fields
|
||||
- Improved error handling in webhook delivery service
|
||||
- Enhanced Redis task storage for webhook config persistence
|
||||
|
||||
## 🌍 Expected Real-World Impact
|
||||
|
||||
### For Web Scraping Workflows
|
||||
- **Reduced Costs**: Less API calls = lower bandwidth and server costs
|
||||
- **Better UX**: Instant notifications improve user experience
|
||||
- **Scalability**: Handle 100s of concurrent jobs without polling overhead
|
||||
|
||||
### For LLM Extraction Pipelines
|
||||
- **Async Processing**: Submit LLM extraction jobs and move on
|
||||
- **Batch Processing**: Queue multiple extractions, get notified as they complete
|
||||
- **Integration**: Easy integration with workflow automation tools (Zapier, n8n, etc.)
|
||||
|
||||
### For Microservices
|
||||
- **Event-Driven**: Perfect for event-driven microservice architectures
|
||||
- **Decoupling**: Decouple job submission from result processing
|
||||
- **Reliability**: Automatic retries ensure webhooks are delivered
|
||||
|
||||
## 🔄 Breaking Changes
|
||||
|
||||
**None!** This release is fully backward compatible.
|
||||
|
||||
- Webhook configuration is optional
|
||||
- Existing code continues to work without modification
|
||||
- Polling is still supported for jobs without webhook config
|
||||
|
||||

|
||||
|
||||
## 🛠️ Migration Guide
|
||||
|
||||
No migration needed! Webhooks are opt-in:
|
||||
|
||||
1. **To use webhooks**: Add `webhook_config` to your job payload
|
||||
2. **To keep polling**: Continue using your existing code
|
||||
|
||||
### Quick Start
|
||||
|
||||
```python
|
||||
# Just add webhook_config to your existing payload
|
||||
payload = {
|
||||
# Your existing configuration
|
||||
"urls": ["https://example.com"],
|
||||
"browser_config": {...},
|
||||
"crawler_config": {...},
|
||||
|
||||
# NEW: Add webhook configuration
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhook",
|
||||
"webhook_data_in_payload": True
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🔧 Configuration
|
||||
|
||||
### Global Webhook Configuration (config.yml)
|
||||
|
||||
```yaml
|
||||
webhooks:
|
||||
enabled: true
|
||||
default_url: "https://myapp.com/webhooks/default" # Optional
|
||||
data_in_payload: false
|
||||
retry:
|
||||
max_attempts: 5
|
||||
initial_delay_ms: 1000
|
||||
max_delay_ms: 32000
|
||||
timeout_ms: 30000
|
||||
headers:
|
||||
User-Agent: "Crawl4AI-Webhook/1.0"
|
||||
```
|
||||
|
||||
## 🚀 Upgrade Instructions
|
||||
|
||||
### Docker
|
||||
|
||||
```bash
|
||||
# Pull the latest image
|
||||
docker pull unclecode/crawl4ai:0.7.6
|
||||
|
||||
# Or use latest tag
|
||||
docker pull unclecode/crawl4ai:latest
|
||||
|
||||
# Run with webhook support
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--env-file .llm.env \
|
||||
--name crawl4ai \
|
||||
unclecode/crawl4ai:0.7.6
|
||||
```
|
||||
|
||||
### Python Package
|
||||
|
||||
```bash
|
||||
pip install --upgrade crawl4ai
|
||||
```
|
||||
|
||||
## 💡 Pro Tips
|
||||
|
||||
1. **Use notification-only mode** for large results - fetch data separately to avoid large webhook payloads
|
||||
2. **Set custom headers** for webhook authentication and request tracking
|
||||
3. **Configure global default webhook** for consistent handling across all jobs
|
||||
4. **Implement idempotent webhook handlers** - same webhook may be delivered multiple times on retry
|
||||
5. **Use structured schemas** with LLM extraction for predictable webhook data
|
||||
|
||||

Docker Webhook Example for Crawl4AI
|
||||
|
||||
This example demonstrates how to use webhooks with the Crawl4AI job queue API.
|
||||
Instead of polling for results, webhooks notify your application when jobs complete.
|
||||
|
||||
Supports both:
|
||||
- /crawl/job - Raw crawling with markdown extraction
|
||||
- /llm/job - LLM-powered content extraction
|
||||
|
||||
Prerequisites:
|
||||
1. Crawl4AI Docker container running on localhost:11235
|
||||
2. Flask installed: pip install flask requests
|
||||
3. LLM API key configured in .llm.env (for LLM extraction examples)
|
||||
|
||||
Usage:
|
||||
1. Run this script: python docker_webhook_example.py
|
||||
2. The webhook server will start on http://localhost:8080
|
||||
3. Jobs will be submitted and webhooks will be received automatically

# Crawl4AI v0.7.6 Release Notes
|
||||
|
||||
*Release Date: October 22, 2025*
|
||||
|
||||
I'm excited to announce Crawl4AI v0.7.6, featuring a complete webhook infrastructure for the Docker job queue API! This release eliminates polling and brings real-time notifications to both crawling and LLM extraction workflows.
|
||||
|
||||
## 🎯 What's New
|
||||
|
||||
### Webhook Support for Docker Job Queue API
|
||||
|
||||
The headline feature of v0.7.6 is comprehensive webhook support for asynchronous job processing. No more constant polling to check if your jobs are done - get instant notifications when they complete!
|
||||
|
||||
**Key Capabilities:**
|
||||
|
||||
- ✅ **Universal Webhook Support**: Both `/crawl/job` and `/llm/job` endpoints now support webhooks
|
||||
- ✅ **Flexible Delivery Modes**: Choose notification-only or include full data in the webhook payload
|
||||
- ✅ **Reliable Delivery**: Exponential backoff retry mechanism (5 attempts: 1s → 2s → 4s → 8s → 16s)
|
||||
- ✅ **Custom Authentication**: Add custom headers for webhook authentication
|
||||
- ✅ **Global Configuration**: Set default webhook URL in `config.yml` for all jobs
|
||||
- ✅ **Task Type Identification**: Distinguish between `crawl` and `llm_extraction` tasks
|
||||
|
||||
### How It Works
|
||||
|
||||
Instead of constantly checking job status:
|
||||
|
||||
**OLD WAY (Polling):**
|
||||
```python
|
||||
# Submit job
|
||||
response = requests.post("http://localhost:11235/crawl/job", json=payload)
|
||||
task_id = response.json()['task_id']
|
||||
|
||||
# Poll until complete
|
||||
while True:
|
||||
status = requests.get(f"http://localhost:11235/crawl/job/{task_id}")
|
||||
if status.json()['status'] == 'completed':
|
||||
break
|
||||
time.sleep(5) # Wait and try again
|
||||
```
|
||||
|
||||
**NEW WAY (Webhooks):**
|
||||
```python
|
||||
# Submit job with webhook
|
||||
payload = {
|
||||
"urls": ["https://example.com"],
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhook",
|
||||
"webhook_data_in_payload": True
|
||||
}
|
||||
}
|
||||
response = requests.post("http://localhost:11235/crawl/job", json=payload)
|
||||
|
||||
# Done! Webhook will notify you when complete
|
||||
# Your webhook handler receives the results automatically
|
||||
```
|
||||
|
||||
### Crawl Job Webhooks
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/crawl/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"urls": ["https://example.com"],
|
||||
"browser_config": {"headless": true},
|
||||
"crawler_config": {"cache_mode": "bypass"},
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/crawl-complete",
|
||||
"webhook_data_in_payload": false,
|
||||
"webhook_headers": {
|
||||
"X-Webhook-Secret": "your-secret-token"
|
||||
}
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
### LLM Extraction Job Webhooks (NEW!)
|
||||
|
||||
```bash
|
||||
curl -X POST http://localhost:11235/llm/job \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{
|
||||
"url": "https://example.com/article",
|
||||
"q": "Extract the article title, author, and publication date",
|
||||
"schema": "{\"type\":\"object\",\"properties\":{\"title\":{\"type\":\"string\"}}}",
|
||||
"provider": "openai/gpt-4o-mini",
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhooks/llm-complete",
|
||||
"webhook_data_in_payload": true
|
||||
}
|
||||
}'
|
||||
```
|
||||
|
||||
### Webhook Payload Structure
|
||||
|
||||
**Success (with data):**
|
||||
```json
|
||||
{
|
||||
"task_id": "llm_1698765432",
|
||||
"task_type": "llm_extraction",
|
||||
"status": "completed",
|
||||
"timestamp": "2025-10-22T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com/article"],
|
||||
"data": {
|
||||
"extracted_content": {
|
||||
"title": "Understanding Web Scraping",
|
||||
"author": "John Doe",
|
||||
"date": "2025-10-22"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Failure:**
|
||||
```json
|
||||
{
|
||||
"task_id": "crawl_abc123",
|
||||
"task_type": "crawl",
|
||||
"status": "failed",
|
||||
"timestamp": "2025-10-22T10:30:00.000000+00:00",
|
||||
"urls": ["https://example.com"],
|
||||
"error": "Connection timeout after 30s"
|
||||
}
|
||||
```
|
||||
|
||||
### Simple Webhook Handler Example
|
||||
|
||||
```python
|
||||
from flask import Flask, request, jsonify
|
||||
|
||||
app = Flask(__name__)
|
||||
|
||||
@app.route('/webhook', methods=['POST'])
|
||||
def handle_webhook():
|
||||
payload = request.json
|
||||
|
||||
task_id = payload['task_id']
|
||||
task_type = payload['task_type']
|
||||
status = payload['status']
|
||||
|
||||
if status == 'completed':
|
||||
if 'data' in payload:
|
||||
# Process data directly
|
||||
data = payload['data']
|
||||
else:
|
||||
# Fetch from API
|
||||
endpoint = 'crawl' if task_type == 'crawl' else 'llm'
|
||||
response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
|
||||
data = response.json()
|
||||
|
||||
# Your business logic here
|
||||
print(f"Job {task_id} completed!")
|
||||
|
||||
elif status == 'failed':
|
||||
error = payload.get('error', 'Unknown error')
|
||||
print(f"Job {task_id} failed: {error}")
|
||||
|
||||
return jsonify({"status": "received"}), 200
|
||||
|
||||
app.run(port=8080)
|
||||
```
|
||||
|
||||
## 📊 Performance Improvements
|
||||
|
||||
- **Reduced Server Load**: Eliminates constant polling requests
|
||||
- **Lower Latency**: Instant notification vs. polling interval delay
|
||||
- **Better Resource Usage**: Frees up client connections while jobs run in background
|
||||
- **Scalable Architecture**: Handles high-volume crawling workflows efficiently
|
||||
|
||||
## 🐛 Bug Fixes
|
||||
|
||||
- Fixed webhook configuration serialization for Pydantic HttpUrl fields
|
||||
- Improved error handling in webhook delivery service
|
||||
- Enhanced Redis task storage for webhook config persistence
|
||||
|
||||
## 🌍 Expected Real-World Impact
|
||||
|
||||
### For Web Scraping Workflows
|
||||
- **Reduced Costs**: Less API calls = lower bandwidth and server costs
|
||||
- **Better UX**: Instant notifications improve user experience
|
||||
- **Scalability**: Handle 100s of concurrent jobs without polling overhead
|
||||
|
||||
### For LLM Extraction Pipelines
|
||||
- **Async Processing**: Submit LLM extraction jobs and move on
|
||||
- **Batch Processing**: Queue multiple extractions, get notified as they complete
|
||||
- **Integration**: Easy integration with workflow automation tools (Zapier, n8n, etc.)
|
||||
|
||||
### For Microservices
|
||||
- **Event-Driven**: Perfect for event-driven microservice architectures
|
||||
- **Decoupling**: Decouple job submission from result processing
|
||||
- **Reliability**: Automatic retries ensure webhooks are delivered
|
||||
|
||||
## 🔄 Breaking Changes
|
||||
|
||||
**None!** This release is fully backward compatible.
|
||||
|
||||
- Webhook configuration is optional
|
||||
- Existing code continues to work without modification
|
||||
- Polling is still supported for jobs without webhook config
|
||||
|
||||

|
||||
|
||||
### New Documentation
|
||||
- **[WEBHOOK_EXAMPLES.md](../deploy/docker/WEBHOOK_EXAMPLES.md)** - Comprehensive webhook usage guide
|
||||
- **[docker_webhook_example.py](../docs/examples/docker_webhook_example.py)** - Working code examples

|
||||
|
||||
## 🛠️ Migration Guide
|
||||
|
||||
No migration needed! Webhooks are opt-in:
|
||||
|
||||
1. **To use webhooks**: Add `webhook_config` to your job payload
|
||||
2. **To keep polling**: Continue using your existing code
|
||||
|
||||
### Quick Start
|
||||
|
||||
```python
|
||||
# Just add webhook_config to your existing payload
|
||||
payload = {
|
||||
# Your existing configuration
|
||||
"urls": ["https://example.com"],
|
||||
"browser_config": {...},
|
||||
"crawler_config": {...},
|
||||
|
||||
# NEW: Add webhook configuration
|
||||
"webhook_config": {
|
||||
"webhook_url": "https://myapp.com/webhook",
|
||||
"webhook_data_in_payload": True
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🔧 Configuration
|
||||
|
||||
### Global Webhook Configuration (config.yml)
|
||||
|
||||
```yaml
|
||||
webhooks:
|
||||
enabled: true
|
||||
default_url: "https://myapp.com/webhooks/default" # Optional
|
||||
data_in_payload: false
|
||||
retry:
|
||||
max_attempts: 5
|
||||
initial_delay_ms: 1000
|
||||
max_delay_ms: 32000
|
||||
timeout_ms: 30000
|
||||
headers:
|
||||
User-Agent: "Crawl4AI-Webhook/1.0"
|
||||
```
|
||||
|
||||
## 🚀 Upgrade Instructions
|
||||
|
||||
### Docker
|
||||
|
||||
```bash
|
||||
# Pull the latest image
|
||||
docker pull unclecode/crawl4ai:0.7.6
|
||||
|
||||
# Or use latest tag
|
||||
docker pull unclecode/crawl4ai:latest
|
||||
|
||||
# Run with webhook support
|
||||
docker run -d \
|
||||
-p 11235:11235 \
|
||||
--env-file .llm.env \
|
||||
--name crawl4ai \
|
||||
unclecode/crawl4ai:0.7.6
|
||||
```
|
||||
|
||||
### Python Package
|
||||
|
||||
```bash
|
||||
pip install --upgrade crawl4ai
|
||||
```
|
||||
|
||||
## 💡 Pro Tips
|
||||
|
||||
1. **Use notification-only mode** for large results - fetch data separately to avoid large webhook payloads
|
||||
2. **Set custom headers** for webhook authentication and request tracking
|
||||
3. **Configure global default webhook** for consistent handling across all jobs
|
||||
4. **Implement idempotent webhook handlers** - same webhook may be delivered multiple times on retry
|
||||
5. **Use structured schemas** with LLM extraction for predictable webhook data
|
||||
|
||||

# 🚀 Crawl4AI v0.7.5: The Docker Hooks & Security Update
|
||||
|
||||
*September 29, 2025 • 8 min read*
|
||||
|
||||
---
|
||||
|
||||
Today I'm releasing Crawl4AI v0.7.5—focused on extensibility and security. This update introduces the Docker Hooks System for pipeline customization, enhanced LLM integration, and important security improvements.
|
||||
|
||||
## 🎯 What's New at a Glance
|
||||
|
||||
- **Docker Hooks System**: Custom Python functions at key pipeline points with function-based API
|
||||
- **Function-Based Hooks**: New `hooks_to_string()` utility with Docker client auto-conversion
|
||||
- **Enhanced LLM Integration**: Custom providers with temperature control
|
||||
- **HTTPS Preservation**: Secure internal link handling
|
||||
- **Bug Fixes**: Resolved multiple community-reported issues
|
||||
- **Improved Docker Error Handling**: Better debugging and reliability
|
||||
|
||||
## 🔧 Docker Hooks System: Pipeline Customization
|
||||
|
||||
Every scraping project needs custom logic—authentication, performance optimization, content processing. Traditional solutions require forking or complex workarounds. Docker Hooks let you inject custom Python functions at 8 key points in the crawling pipeline.
|
||||
|
||||
### Real Example: Authentication & Performance
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
# Real working hooks for httpbin.org
|
||||
hooks_config = {
|
||||
"on_page_context_created": """
|
||||
async def hook(page, context, **kwargs):
|
||||
print("Hook: Setting up page context")
|
||||
# Block images to speed up crawling
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
print("Hook: Images blocked")
|
||||
return page
|
||||
""",
|
||||
|
||||
"before_retrieve_html": """
|
||||
async def hook(page, context, **kwargs):
|
||||
print("Hook: Before retrieving HTML")
|
||||
# Scroll to bottom to load lazy content
|
||||
await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
|
||||
await page.wait_for_timeout(1000)
|
||||
print("Hook: Scrolled to bottom")
|
||||
return page
|
||||
""",
|
||||
|
||||
"before_goto": """
|
||||
async def hook(page, context, url, **kwargs):
|
||||
print(f"Hook: About to navigate to {url}")
|
||||
# Add custom headers
|
||||
await page.set_extra_http_headers({
|
||||
'X-Test-Header': 'crawl4ai-hooks-test'
|
||||
})
|
||||
return page
|
||||
"""
|
||||
}
|
||||
|
||||
# Test with Docker API
|
||||
payload = {
|
||||
"urls": ["https://httpbin.org/html"],
|
||||
"hooks": {
|
||||
"code": hooks_config,
|
||||
"timeout": 30
|
||||
}
|
||||
}
|
||||
|
||||
response = requests.post("http://localhost:11235/crawl", json=payload)
|
||||
result = response.json()
|
||||
|
||||
if result.get('success'):
|
||||
print("✅ Hooks executed successfully!")
|
||||
print(f"Content length: {len(result.get('markdown', ''))} characters")
|
||||
```
|
||||
|
||||
**Available Hook Points:**
|
||||
- `on_browser_created`: Browser setup
|
||||
- `on_page_context_created`: Page context configuration
|
||||
- `before_goto`: Pre-navigation setup
|
||||
- `after_goto`: Post-navigation processing
|
||||
- `on_user_agent_updated`: User agent changes
|
||||
- `on_execution_started`: Crawl initialization
|
||||
- `before_retrieve_html`: Pre-extraction processing
|
||||
- `before_return_html`: Final HTML processing
|
||||
|
||||
### Function-Based Hooks API
|
||||
|
||||
Writing hooks as strings works, but lacks IDE support and type checking. v0.7.5 introduces a function-based approach with automatic conversion!
|
||||
|
||||
**Option 1: Using the `hooks_to_string()` Utility**
|
||||
|
||||
```python
|
||||
from crawl4ai import hooks_to_string
|
||||
import requests
|
||||
|
||||
# Define hooks as regular Python functions (with full IDE support!)
|
||||
async def on_page_context_created(page, context, **kwargs):
|
||||
"""Block images to speed up crawling"""
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
await page.set_viewport_size({"width": 1920, "height": 1080})
|
||||
return page
|
||||
|
||||
async def before_goto(page, context, url, **kwargs):
|
||||
"""Add custom headers"""
|
||||
await page.set_extra_http_headers({
|
||||
'X-Crawl4AI': 'v0.7.5',
|
||||
'X-Custom-Header': 'my-value'
|
||||
})
|
||||
return page
|
||||
|
||||
# Convert functions to strings
|
||||
hooks_code = hooks_to_string({
|
||||
"on_page_context_created": on_page_context_created,
|
||||
"before_goto": before_goto
|
||||
})
|
||||
|
||||
# Use with REST API
|
||||
payload = {
|
||||
"urls": ["https://httpbin.org/html"],
|
||||
"hooks": {"code": hooks_code, "timeout": 30}
|
||||
}
|
||||
response = requests.post("http://localhost:11235/crawl", json=payload)
|
||||
```
|
||||
|
||||
**Option 2: Docker Client with Automatic Conversion (Recommended!)**
|
||||
|
||||
```python
|
||||
from crawl4ai.docker_client import Crawl4aiDockerClient
|
||||
|
||||
# Define hooks as functions (same as above)
|
||||
async def on_page_context_created(page, context, **kwargs):
|
||||
await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
|
||||
return page
|
||||
|
||||
async def before_retrieve_html(page, context, **kwargs):
|
||||
# Scroll to load lazy content
|
||||
await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")

**Benefits of Function-Based Hooks:**
|
||||
- ✅ Full IDE support (autocomplete, syntax highlighting)
|
||||
- ✅ Type checking and linting
|
||||
- ✅ Easier to test and debug
|
||||
- ✅ Reusable across projects
|
||||
- ✅ Automatic conversion in Docker client
|
||||
- ✅ No breaking changes - string hooks still work!

## 🤖 Enhanced LLM Integration
|
||||
|
||||
Enhanced LLM integration with custom providers, temperature control, and base URL configuration.
|
||||
|
||||
### Multi-Provider Support
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
|
||||
from crawl4ai.extraction_strategy import LLMExtractionStrategy
|
||||
|
||||
# Test with different providers
|
||||
async def test_llm_providers():
|
||||
# OpenAI with custom temperature
|
||||
openai_strategy = LLMExtractionStrategy(
|
||||
provider="gemini/gemini-2.5-flash-lite",
|
||||
api_token="your-api-token",
|
||||
temperature=0.7, # New in v0.7.5
|
||||
instruction="Summarize this page in one sentence"
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
result = await crawler.arun(
|
||||
"https://example.com",
|
||||
config=CrawlerRunConfig(extraction_strategy=openai_strategy)
|
||||
)
|
||||
|
||||
if result.success:
|
||||
print("✅ LLM extraction completed")
|
||||
print(result.extracted_content)
|
||||
|
||||
# Docker API with enhanced LLM config
|
||||
llm_payload = {
|
||||
"url": "https://example.com",
|
||||
"f": "llm",
|
||||
"q": "Summarize this page in one sentence.",
|
||||
"provider": "gemini/gemini-2.5-flash-lite",
|
||||
"temperature": 0.7
|
||||
}
|
||||
|
||||
response = requests.post("http://localhost:11235/md", json=llm_payload)
|
||||
```
|
||||
|
||||
**New Features:**
|
||||
- Custom `temperature` parameter for creativity control
|
||||
- `base_url` for custom API endpoints
|
||||
- Multi-provider environment variable support
|
||||
- Docker API integration
|
||||
|
||||
## 🔒 HTTPS Preservation
|
||||
|
||||
**The Problem:** Modern web apps require HTTPS everywhere. When crawlers downgrade internal links from HTTPS to HTTP, authentication breaks and security warnings appear.
|
||||
|
||||
**Solution:** HTTPS preservation maintains secure protocols throughout crawling.
|
||||
|
||||
```python
|
||||
from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, FilterChain, URLPatternFilter, BFSDeepCrawlStrategy
|
||||
|
||||
async def test_https_preservation():
|
||||
# Enable HTTPS preservation
|
||||
url_filter = URLPatternFilter(
|
||||
patterns=["^(https:\/\/)?quotes\.toscrape\.com(\/.*)?$"]
|
||||
)
|
||||
|
||||
config = CrawlerRunConfig(
|
||||
exclude_external_links=True,
|
||||
preserve_https_for_internal_links=True, # New in v0.7.5
|
||||
deep_crawl_strategy=BFSDeepCrawlStrategy(
|
||||
max_depth=2,
|
||||
max_pages=5,
|
||||
filter_chain=FilterChain([url_filter])
|
||||
)
|
||||
)
|
||||
|
||||
async with AsyncWebCrawler() as crawler:
|
||||
async for result in await crawler.arun(
|
||||
url="https://quotes.toscrape.com",
|
||||
config=config
|
||||
):
|
||||
# All internal links maintain HTTPS
|
||||
internal_links = [link['href'] for link in result.links['internal']]
|
||||
https_links = [link for link in internal_links if link.startswith('https://')]
|
||||
|
||||
print(f"HTTPS links preserved: {len(https_links)}/{len(internal_links)}")
|
||||
for link in https_links[:3]:
|
||||
print(f" → {link}")
|
||||
```
|
||||
|
||||
## 🛠️ Bug Fixes and Improvements
|
||||
|
||||
### Major Fixes
|
||||
- **URL Processing**: Fixed '+' sign preservation in query parameters (#1332)
|
||||
- **Proxy Configuration**: Enhanced proxy string parsing (old `proxy` parameter deprecated)
|
||||
- **Docker Error Handling**: Comprehensive error messages with status codes
|
||||
- **Memory Management**: Fixed leaks in long-running sessions
|
||||
- **JWT Authentication**: Fixed Docker JWT validation issues (#1442)
|
||||
- **Playwright Stealth**: Fixed stealth features for Playwright integration (#1481)
|
||||
- **API Configuration**: Fixed config handling to prevent overriding user-provided settings (#1505)
|
||||

|
||||
- **LLM Provider Support**: Fixed custom LLM provider integration for adaptive crawler (#1291)
|
||||
- **Performance Issues**: Resolved backoff strategy failures and timeout handling (#989)
|
||||
|
||||
### Community-Reported Issues Fixed
|
||||
This release addresses multiple issues reported by the community through GitHub issues and Discord discussions:
|
||||
- Fixed browser configuration reference errors
|
||||
- Resolved dependency conflicts with cssselect
|
||||
- Improved error messaging for failed authentications
|
||||
- Enhanced compatibility with various proxy configurations
|
||||
- Fixed edge cases in URL normalization
|
||||
|
||||
### Configuration Updates
|
||||
```python
|
||||
# Old proxy config (deprecated)
|
||||
# browser_config = BrowserConfig(proxy="http://proxy:8080")
|
||||
|
||||
# New enhanced proxy config
|
||||
browser_config = BrowserConfig(
|
||||
proxy_config={
|
||||
"server": "http://proxy:8080",
|
||||
"username": "optional-user",
|
||||
"password": "optional-pass"
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
## 🔄 Breaking Changes
|
||||
|
||||
1. **Python 3.10+ Required**: Upgrade from Python 3.9
|
||||
2. **Proxy Parameter Deprecated**: Use new `proxy_config` structure
|
||||
3. **New Dependency**: Added `cssselect` for better CSS handling
|
||||
|
||||

Crawl4AI v0.7.6 Release Demo
|
||||
============================
|
||||
|
||||
This demo showcases the major feature in v0.7.6:
|
||||
**Webhook Support for Docker Job Queue API**
|
||||
|
||||
Features Demonstrated:
|
||||
1. Asynchronous job processing with webhook notifications
|
||||
2. Webhook support for /crawl/job endpoint
|
||||
3. Webhook support for /llm/job endpoint
|
||||
4. Notification-only vs data-in-payload modes
|
||||
5. Custom webhook headers for authentication
|
||||
6. Structured extraction with JSON schemas
|
||||
7. Exponential backoff retry for reliable delivery
|
||||
|
||||
Prerequisites:
|
||||
- Crawl4AI Docker container running on localhost:11235
|
||||
- Flask installed: pip install flask requests
|
||||
- LLM API key configured (for LLM examples)
|
||||

🚀 Crawl4AI v0.7.5 - Docker Hooks System Complete Demonstration
|
||||
================================================================
|
||||
|
||||
This file demonstrates the NEW Docker Hooks System introduced in v0.7.5.
|
||||
|
||||
The Docker Hooks System is a completely NEW feature that provides pipeline
|
||||
customization through user-provided Python functions. It offers three approaches:
|
||||
|
||||
1. String-based hooks for REST API
|
||||
2. hooks_to_string() utility to convert functions
|
||||
3. Docker Client with automatic conversion (most convenient)
|
||||
|
||||
All three approaches are part of this NEW v0.7.5 feature!
|
||||
|
||||
Perfect for video recording and demonstration purposes.
|
||||
|
||||
Requirements:
|
||||
- Docker container running: docker run -p 11235:11235 unclecode/crawl4ai:latest
|
||||
- crawl4ai v0.7.5 installed: pip install crawl4ai==0.7.5

# Webhook Feature Test Script
|
||||
|
||||
This directory contains a comprehensive test script for the webhook feature implementation.
|
||||
|
||||
## Overview
|
||||
|
||||
The `test_webhook_feature.sh` script automates the entire process of testing the webhook feature:
|
||||
|
||||
1. ✅ Fetches and switches to the webhook feature branch
|
||||
2. ✅ Activates the virtual environment
|
||||
3. ✅ Installs all required dependencies
|
||||
4. ✅ Starts Redis server in background
|
||||
5. ✅ Starts Crawl4AI server in background
|
||||
6. ✅ Runs webhook integration test
|
||||
7. ✅ Verifies job completion via webhook
|
||||
8. ✅ Cleans up and returns to original branch
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Python 3.10+
|
||||
- Virtual environment already created (`venv/` in project root)
|
||||
- Git repository with the webhook feature branch
|
||||
- `redis-server` (script will attempt to install if missing)
|
||||
- `curl` and `lsof` commands available
|
||||
|
||||
## Usage
|
||||
|
||||
### Quick Start
|
||||
|
||||
From the project root:
|
||||
|
||||
```bash
|
||||
./tests/test_webhook_feature.sh
|
||||
```
|
||||
|
||||
Or from the tests directory:
|
||||
|
||||
```bash
|
||||
cd tests
|
||||
./test_webhook_feature.sh
|
||||
```
|
||||
|
||||
### What the Script Does
|
||||
|
||||
#### Step 1: Branch Management
|
||||
- Saves your current branch
|
||||
- Fetches the webhook feature branch from remote
|
||||
- Switches to the webhook feature branch
|
||||
|
||||
#### Step 2: Environment Setup
|
||||
- Activates your existing virtual environment
|
||||
- Installs dependencies from `deploy/docker/requirements.txt`
|
||||
- Installs Flask for the webhook receiver
|
||||
|
||||
#### Step 3: Service Startup
|
||||
- Starts Redis server on port 6379
|
||||
- Starts Crawl4AI server on port 11235
|
||||
- Waits for server health check to pass
|
||||
|
||||
#### Step 4: Webhook Test
|
||||
- Creates a webhook receiver on port 8080
|
||||
- Submits a crawl job for `https://example.com` with webhook config
|
||||
- Waits for webhook notification (60s timeout)
|
||||
- Verifies webhook payload contains expected data
|
||||
|
||||
#### Step 5: Cleanup
|
||||
- Stops webhook receiver
|
||||
- Stops Crawl4AI server
|
||||
- Stops Redis server
|
||||
- Returns to your original branch
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Server Failed to Start
|
||||
|
||||
If the server fails to start, check the logs:
|
||||
|
||||
```bash
|
||||
tail -100 /tmp/crawl4ai_server.log
|
||||
```
|
||||
|
||||
Common issues:
|
||||
- Port 11235 already in use: `lsof -ti:11235 | xargs kill -9`
|
||||
- Missing dependencies: Check that all packages are installed
|
||||
|
||||
### Redis Connection Failed
|
||||
|
||||
Check if Redis is running:
|
||||
|
||||
```bash
|
||||
redis-cli ping
|
||||
# Should return: PONG
|
||||
```
|
||||
|
||||
If not running:
|
||||
|
||||
```bash
|
||||
redis-server --port 6379 --daemonize yes
|
||||
```
|
||||
|
||||
### Webhook Not Received
|
||||
|
||||
The script has a 60-second timeout for webhook delivery. If the webhook isn't received:
|
||||
|
||||
1. Check server logs: `/tmp/crawl4ai_server.log`
|
||||
2. Verify webhook receiver is running on port 8080
|
||||
3. Check network connectivity between components
|
||||
|
||||
### Script Interruption
|
||||
|
||||
If the script is interrupted (Ctrl+C), cleanup happens automatically via trap. The script will:
|
||||
- Kill all background processes
|
||||
- Stop Redis
|
||||
- Return to your original branch
|
||||
|
||||
To manually cleanup if needed:
|
||||
|
||||
```bash
|
||||
# Kill processes by port
|
||||
lsof -ti:11235 | xargs kill -9 # Server
|
||||
lsof -ti:8080 | xargs kill -9 # Webhook receiver
|
||||
lsof -ti:6379 | xargs kill -9 # Redis
|
||||
|
||||
# Return to your branch
|
||||
git checkout develop # or your branch name
|
||||
```
|
||||
|
||||
## Testing Different URLs
|
||||
|
||||
To test with a different URL, modify the script or create a custom test:
|
||||
|
||||
```python
|
||||
payload = {
|
||||
"urls": ["https://your-url-here.com"],
|
||||
"browser_config": {"headless": True},
|
||||
"crawler_config": {"cache_mode": "bypass"},
|
||||
"webhook_config": {
|
||||
"webhook_url": "http://localhost:8080/webhook",
|
||||
"webhook_data_in_payload": True
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Files Generated
|
||||
|
||||
The script creates temporary files:
|
||||
|
||||
- `/tmp/crawl4ai_server.log` - Server output logs
|
||||
- `/tmp/test_webhook.py` - Webhook test Python script
|
||||
|
||||
These are not cleaned up automatically so you can review them after the test.
|
||||
|
||||
## Exit Codes
|
||||
|
||||
- `0` - All tests passed successfully
|
||||
- `1` - Test failed (check output for details)
|
||||
|
||||
## Safety Features
|
||||
|
||||
- ✅ Automatic cleanup on exit, interrupt, or error
|
||||
- ✅ Returns to original branch on completion
|
||||
- ✅ Kills all background processes
|
||||
- ✅ Comprehensive error handling
|
||||
- ✅ Colored output for easy reading
|
||||
- ✅ Detailed logging at each step
|
||||
|
||||
## Notes
|
||||
|
||||
- The script uses `set -e` to exit on any command failure
|
||||
- All background processes are tracked and cleaned up
|
||||
- The virtual environment must exist before running
|
||||
- Redis must be available (installed or installable via apt-get/brew)
|
||||
|
||||
## Integration with CI/CD
|
||||
|
||||
This script can be integrated into CI/CD pipelines:
|
||||
|
||||
```yaml

# 2. Installing dependencies
|
||||
# 3. Starting the server
|
||||
# 4. Running webhook tests
|
