### New Features: - **Text-Only Mode**: Added support for text-only crawling by disabling images, JavaScript, GPU, and other non-essential features. - **Light Mode**: Optimized browser settings to reduce resource usage and improve efficiency during crawling. - **Dynamic Viewport Adjustment**: Automatically adjusts viewport dimensions based on content size, ensuring accurate rendering and scaling. - **Full Page Scanning**: Introduced a feature to scroll and capture dynamic content for pages with infinite scroll or lazy-loading elements. - **Session Management**: Added `create_session` method for creating and managing browser sessions with unique IDs. ### Improvements: - Unified viewport handling across contexts by dynamically setting dimensions using `self.viewport_width` and `self.viewport_height`. - Enhanced logging and error handling for viewport adjustments, page scanning, and content evaluation. - Reduced resource usage with additional browser flags for both `light_mode` and `text_only` configurations. - Improved handling of cookies, headers, and proxies in session creation. ### Refactoring: - Removed hardcoded viewport dimensions and replaced them with dynamic configurations. - Cleaned up unused and commented-out code for better readability and maintainability. - Introduced defaults for frequently used parameters like `delay_before_return_html`. ### Fixes: - Resolved potential inconsistencies in viewport handling. - Improved robustness of content loading and dynamic adjustments to avoid failures and timeouts. ### Docs Update: - Updated schema usage in `quickstart_async.py` example: - Changed `OpenAIModelFee.schema()` to `OpenAIModelFee.model_json_schema()` for compatibility. - Enhanced LLM extraction instruction documentation. This commit introduces significant enhancements to improve efficiency, flexibility, and reliability of the crawler strategy.
