Adds a new BrowserManager implementation with browser pooling and page pre-warming capabilities:
- Adds support for managing multiple browser instances per configuration
- Implements page pre-warming for improved performance
- Adds configurable behavior for when no browsers are available
- Includes comprehensive status reporting and monitoring
- Maintains backward compatibility with existing API
- Adds demo script showcasing new features
BREAKING CHANGE: BrowserManager API now returns a strategy instance along with page and context
Major refactoring of browser strategy implementations to improve code organization and reliability:
- Move CrawlResultContainer and RunManyReturn types from async_webcrawler to models.py
- Simplify browser lifecycle management in AsyncWebCrawler
- Standardize browser strategy interface with _generate_page method
- Improve headless mode handling and browser args construction
- Clean up Docker and Playwright strategy implementations
- Fix session management and context handling across strategies
BREAKING CHANGE: Browser strategy interface has changed with new _generate_page method requirement
Moves common browser functionality into BaseBrowserStrategy class to reduce code duplication and improve maintainability. Key changes:
- Adds shared browser argument building and session management to base class
- Standardizes storage state handling across strategies
- Improves process cleanup and error handling
- Consolidates CDP URL management and container lifecycle
BREAKING CHANGE: Changes browser_mode="custom" to "cdp" for consistency
Reorganize browser strategy code into separate modules for better maintainability and separation of concerns. Improve Docker implementation with:
- Add Alpine and Debian-based Dockerfiles for better container options
- Enhance Docker registry to share configuration with BuiltinBrowserStrategy
- Add CPU and memory limits to container configuration
- Improve error handling and logging
- Update documentation and examples
BREAKING CHANGE: DockerConfig, DockerRegistry, and DockerUtils have been moved to new locations and their APIs have been updated.
Implements a new browser strategy that runs Chrome in Docker containers,
providing better isolation and cross-platform consistency. Features include:
- Connect and launch modes for different container configurations
- Persistent storage support for maintaining browser state
- Container registry for efficient reuse
- Comprehensive test suite for Docker browser functionality
This addition allows users to run browser automation workloads in isolated
containers, improving security and resource management.
Enhance storage state persistence mechanism in CDP browser strategy by:
- Explicitly saving storage state for each browser context
- Using proper file path for storage state
- Removing unnecessary sleep delay
Also includes test improvements:
- Simplified test configurations in playwright tests
- Temporarily disabled some CDP tests
Remove PagePoolConfig in favor of direct page management in browser strategies.
Add get_pages() method for efficient parallel page creation.
Improve storage state handling and persistence.
Add comprehensive parallel crawling tests and performance analysis.
BREAKING CHANGE: Removed PagePoolConfig class and related functionality.
Adds a new browser management system with strategy pattern implementation:
- Introduces BrowserManager class with strategy pattern support
- Adds PlaywrightBrowserStrategy, CDPBrowserStrategy, and BuiltinBrowserStrategy
- Implements BrowserProfileManager for profile management
- Adds PagePoolConfig for browser page pooling
- Includes comprehensive test suite for all browser strategies
BREAKING CHANGE: Browser management has been moved to browser/ module. Direct usage of browser_manager.py and browser_profiler.py is deprecated.
Implements a persistent browser management system that allows running a single shared browser instance
that can be reused across multiple crawler sessions. Key changes include:
- Added browser_mode config option with 'builtin', 'dedicated', and 'custom' modes
- Implemented builtin browser management in BrowserProfiler
- Added CLI commands for managing builtin browser (start, stop, status, restart, view)
- Modified browser process handling to support detached processes
- Added automatic builtin browser setup during package installation
BREAKING CHANGE: The browser_mode config option changes how browser instances are managed
Add new features to enhance browser automation and HTML extraction:
- Add CDP browser launch capability with customizable ports and profiles
- Implement JsonLxmlExtractionStrategy for faster HTML parsing
- Add CLI command 'crwl cdp' for launching standalone CDP browsers
- Support connecting to external CDP browsers via URL
- Optimize selector caching and context-sensitive queries
BREAKING CHANGE: LLMConfig import path changed from crawl4ai.types to crawl4ai
