Enhance Async Crawler with storage state handling
- Updated Async Crawler to support storage state management.
- Added error handling for URL validation in Async Web Crawler.
- Modified README logo and improved .gitignore entries.

- Enhanced markdown generation with a new generator class
- Improved sanitization and utility functions
- Added contributor details and pull request acknowledgments
- Updated documentation for clearer usage scenarios
- Adjusted tests to reflect class name changes
- Introduced AsyncDatabaseManager for async DB management.
- Added migration feature to transition to file-based storage.
- Enhanced web crawler with improved caching logic.
- Updated requirements and setup for async processing.
- Another thing this commit introduces is the concept of the Relevance Content Filter. This is an improvement over Fit Markdown. This class of strategies aims to extract the main content from a given page - the part that really matters and is useful to be processed. One strategy has been created using the BM25 algorithm, which finds chunks of text from the web page relevant to its title, descriptions, and keywords, or supports a given user query and matches them. The result is then returned to the main engine to be converted to Markdown. Plans include adding approaches using language models as well.
- The cache database was updated to hold information about response headers and downloaded files.
• Add smart overlay removal system for handling popups and modals
• Improve screenshot functionality with configurable timing controls
• Implement URL normalization and enhanced link processing
• Add custom base directory support for cache storage
• Refine external content filtering and social media domain handling
This commit significantly improves the crawler's ability to handle modern
websites by automatically removing intrusive overlays and providing better
screenshot capabilities. URL handling is now more robust with proper
normalization and duplicate detection. The cache system is more flexible
with customizable base directory support.

This code change updates the `LLMExtractionStrategy` class to handle schema extraction when the schema is non-empty. Previously, the schema extraction was only triggered when the `extract_type` was set to "schema", regardless of whether a schema was provided. With this update, the schema extraction will only be performed if the `extract_type` is "schema" and a non-empty schema is provided. This ensures that the extraction strategy behaves correctly and avoids unnecessary schema extraction when not needed. Also "numpy" is removed from default installation mode.
The code change removes the dot from the image format in the `get_content_of_website_optimized` function. This change ensures consistency in the image format and improves the functionality.
The code change sets the `image_size` variable to 0 in the `get_content_of_website_optimized` function. This change is made to temporarily disable fetching the image file size, which was causing performance issues. The image size will be fetched in a future update to improve the functionality.
A slew of exciting updates to improve the crawler's stability and robustness! 🎉
- 💻 **UTF encoding fix**: Resolved the Windows \"charmap\" error by adding UTF encoding.
- 🛡️ **Error handling**: Implemented MaxRetryError exception handling in LocalSeleniumCrawlerStrategy.
- 🧹 **Input sanitization**: Improved input sanitization and handled encoding issues in LLMExtractionStrategy.
- 🚮 **Database cleanup**: Removed existing database file and initialized a new one.
This commit updates the version number to v0.2.73 and makes corresponding changes in the README.md and Dockerfile.
Docker file install the default mode, this resolve many of installation issues.
Additionally, the installation instructions are updated to include support for different modes. Setup.py doesn't have anymore dependancy on Spacy.
The change log is also updated to reflect these changes.
Supporting websites need with-head browser.
This commit adds a page load check for the LocalSeleniumCrawlerStrategy in the `crawl` method. The `_ensure_page_load` method is introduced to ensure that the page has finished loading before proceeding. This helps to prevent issues with incomplete page sources and improves the reliability of the crawler.
The code changes in this commit add the `screenshot` parameter to the `crawl_urls` function in `main.py`. This allows users to specify whether they want to take a screenshot of the page during the crawling process. The default value is `False`.
This commit message follows the established convention of starting with a type (feat for feature) and providing a concise and descriptive summary of the changes made.
