Basic Usage

import asyncio
from src.core.browser_controller import BrowserController
from src.config.browser_config import BrowserConfig
from src.types.browser_types import BrowserType

async def basic_example():

    config = BrowserConfig(
        browser_type=BrowserType.CHROME,
        headless=True,  # Set to False to see browser window
        window_size=(1280, 720)
    )
    
    # Use async context manager for automatic cleanup
    async with BrowserController(config) as controller:
        # Create a session
        session = await controller.create_session()
        
        try:
            # Navigate and interact
            await session.navigate_to("https://example.com")
            title = await session.get_title()
            
            # Find and click elements
            button = await session.find_element("button.submit")
            if button:
                await session.click_element("button.submit")
            
            # Take screenshot
            await session.take_screenshot("example.png")
            
            print(f"Page title: {title}")
            
        finally:
            await controller.close_session(session.session_id)

# Run the automation
asyncio.run(basic_example())

LAM Integration Example

class LAMWebAutomation:
    """Example integration with LAM (Large Action Model) system"""
    
    def __init__(self):
        self.browser_controller = None
        self.action_planner = None      # Your LAM action planner
        self.content_analyzer = None    # Your LAM content analyzer  
        self.decision_engine = None     # Your LAM decision engine
    
    async def execute_web_task(self, task_description: str):
        """Execute high-level web task using LAM + Browser Controller"""
        
        # 1. Plan actions with LAM
        actions = await self.action_planner.plan(task_description)
        
        # 2. Execute with Browser Controller
        async with BrowserController(config) as controller:
            session = await controller.create_session()
            
            try:
                for action in actions:
                    if action.type == "navigate":
                        await session.navigate_to(action.url)
                    elif action.type == "extract":
                        content = await session.get_element_text(action.selector)
                        analysis = await self.content_analyzer.analyze(content)
                    elif action.type == "decide":
                        page_state = await session.get_page_info()
                        decision = await self.decision_engine.decide(page_state)
                    # ... more action types
                    
            finally:
                await controller.close_session(session.session_id)

🚀 Performance & Optimization

Configuration Tips

# For maximum speed (headless)
config = BrowserConfig(
    browser_type=BrowserType.CHROME,
    headless=True,
    browser_options={
        "disable_images": True,
        "disable_javascript": False,  # Keep if needed for functionality
        "disable_plugins": True,
        "disable_extensions": True
    }
)

# For development (visible)
config = BrowserConfig(
    browser_type=BrowserType.CHROME,
    headless=False,
    window_size=(1920, 1080),
    page_load_timeout=30
)

Resource Management

# Always use context managers
async with BrowserController(config) as controller:
    session = await controller.create_session()
    try:
        # Your automation code
        pass
    finally:
        await controller.close_session(session.session_id)

# Monitor session count
print(f"Active sessions: {controller.get_session_count()}")
