* pulled in next branch and resolved conflicts
* feat: Add gemini and deepseek providers. Make ignore_cache in llm content filter to true by default to avoid confusions
* Refactor: Update LlmConfig in LLMExtractionStrategy class and deprecate old params
* updated tests, docs and readme
Implements a new AsyncHTTPCrawlerStrategy class that provides a fast, memory-efficient alternative to browser-based crawling. Features include:
- Support for HTTP/HTTPS requests with configurable methods, headers, and timeouts
- File and raw content handling capabilities
- Streaming response processing for large files
- Customizable request/response hooks
- Comprehensive error handling
Also refactors browser management code into separate module for better organization.
Split deep crawling code into separate strategy files for better organization and maintainability. Added new BFF (Best First) and DFS crawling strategies. Introduced base strategy class and common types.
BREAKING CHANGE: Deep crawling implementation has been split into multiple files. Import paths for deep crawling strategies have changed.
Restructure deep crawling code into a dedicated module with improved organization:
- Move deep crawl logic from async_deep_crawl.py to deep_crawling/
- Create separate files for BFS strategy, filters, and scorers
- Improve code organization and maintainability
- Add optimized implementations for URL filtering and scoring
- Rename DeepCrawlHandler to DeepCrawlDecorator for clarity
BREAKING CHANGE: DeepCrawlStrategy and BreadthFirstSearchStrategy imports need to be updated to new package structure
Major reorganization of the project structure:
- Moved legacy synchronous crawler code to legacy folder
- Removed deprecated CLI and docs manager
- Consolidated version manager into utils.py
- Added CrawlerHub to __init__.py exports
- Fixed type hints in async_webcrawler.py
- Fixed minor bugs in chunking and crawler strategies
BREAKING CHANGE: Removed synchronous WebCrawler, CLI, and docs management functionality. Users should migrate to AsyncWebCrawler.
Add support for checking and respecting robots.txt rules before crawling websites:
- Implement RobotsParser class with SQLite caching
- Add check_robots_txt parameter to CrawlerRunConfig
- Integrate robots.txt checking in AsyncWebCrawler
- Update documentation with robots.txt compliance examples
- Add tests for robot parser functionality
The cache uses WAL mode for better concurrency and has a default TTL of 7 days.
Adds new static method generate_schema() to JsonElementExtractionStrategy classes
that can automatically generate extraction schemas using LLM (OpenAI or Ollama).
This provides a convenient way to bootstrap extraction schemas while maintaining
the performance benefits of selector-based extraction.
Key changes:
- Added generate_schema() static method to base extraction strategy
- Added support for both CSS and XPath schema generation
- Updated documentation with examples and best practices
- Added new prompt templates for schema generation
Add streaming capability to crawler configurations and introduce clone() methods
for both BrowserConfig and CrawlerRunConfig to support immutable config updates.
Move stream parameter from arun_many() method to CrawlerRunConfig.
BREAKING CHANGE: Removed stream parameter from AsyncWebCrawler.arun_many() method.
Use config.stream=True instead.
Add shared_data parameter to CrawlerRunConfig to allow data sharing between hooks.
Implement browser context reuse based on config signatures to improve memory usage.
Fix Firefox/Webkit channel settings.
Add config parameter to hook callbacks for better context access.
Remove debug print statements.
BREAKING CHANGE: Hook callback signatures now include config parameter
Add new streaming capability to the MemoryAdaptiveDispatcher and AsyncWebCrawler
to allow processing URLs with real-time result streaming. This enables
processing results as they become available rather than waiting for all
URLs to complete.
Key changes:
- Add run_urls_stream method to MemoryAdaptiveDispatcher
- Update AsyncWebCrawler.arun_many to support streaming mode
- Add result queue for better result handling
- Improve type hints and documentation
BREAKING CHANGE: The return type of arun_many now depends on the 'stream'
parameter, returning either List[CrawlResult] or AsyncGenerator[CrawlResult, None]
Add new LLMContentFilter class that uses LLMs to generate high-quality markdown content:
- Implement intelligent content filtering with customizable instructions
- Add chunk processing for handling large documents
- Support parallel processing of content chunks
- Include caching mechanism for filtered results
- Add usage tracking and statistics
- Update documentation with examples and use cases
Also includes minor changes:
- Disable Pydantic warnings in __init__.py
- Add new prompt template for content filtering
Make fields in MediaItem and Link models optional with default values to prevent validation errors when data is incomplete. Also expose BaseDispatcher in __init__ and fix markdown field handling in database manager.
BREAKING CHANGE: MediaItem and Link model fields are now optional with default values which may affect existing code expecting required fields.
