Production-Ready Browser Automation Component
A sophisticated, async-based browser automation framework designed for Large Action Model (LAM) web automation systems.
The Browser Controller is a complete, production-ready browser automation solution built with modern Python patterns. It provides:
- High-Performance: Full async/await support for concurrent operations
- Multi-Browser: Chrome, Firefox, Edge with automatic driver management
- Session Management: Advanced session lifecycle and resource management
- Type Safety: Complete type annotations with Pydantic validation
- Enterprise Ready: Comprehensive logging, error handling, and testing
- π Multi-browser support (Chrome, Firefox, Edge, Safari)
- π§ Advanced session management and lifecycle control
- π± Mobile device emulation and viewport management
- πͺ Cookie and storage handling
- π― Element interaction (click, type, wait, screenshot)
- π Async/await support for high-performance automation
- π‘οΈ Comprehensive error handling with custom exception hierarchy
- π Structured logging with Loguru for debugging and monitoring
- βοΈ Smart configuration with Pydantic validation
- π§ͺ Full test coverage with both unit and integration tests
- Context Managers: Automatic resource cleanup and session management
- Wait Strategies: Smart waiting for dynamic content and AJAX
- Multi-Session Support: Handle multiple browser sessions concurrently
- Screenshot Capture: Full page and element-specific screenshots
- Form Automation: Advanced form filling and submission
- Proxy Support: HTTP/HTTPS proxy configuration
- Browser Options: Headless mode, custom user agents, window sizing
