Puppeteer Configurations

This page covers advanced Puppeteer configurations for users who have already established basic connections to Browserless. If you haven't set up a basic Puppeteer connection yet, start with our Connecting Puppeteer guide.

Here are some advanced configurations you can explore:

Advanced Monitoring and Debugging​

CDP Performance Monitoring​

Access Chrome DevTools Protocol to collect real-time browser performance metrics through direct CDP session communication:

const client = await page.target().createCDPSession();
await client.send('Performance.enable');

// Get performance metrics
const metrics = await client.send('Performance.getMetrics');
console.log('Performance metrics:', metrics);

Network Request Monitoring​

Implement comprehensive network activity tracking through Puppeteer's event-driven request/response lifecycle monitoring:

page.on('request', request => {
  console.log('→', request.method(), request.url());
});

page.on('response', response => {
  // Check if response indicates an error (status codes 400-599)  
  if (!response.ok()) {
    console.log('✗', response.status(), response.url());
  }
});

page.on('requestfailed', request => {
  // Log network-level failures: timeouts, DNS errors, connection refused  
  console.log('✗ Failed:', request.url(), request.failure().errorText);
});

Performance Optimization​

Package Optimization​

Switch to puppeteer-core for production deployments to reduce bundle size:

npm install puppeteer-core

For comprehensive performance optimization techniques including network round-trip reduction and navigation settings, see our Best Practices guide.

Advanced Launch Configuration​

For complex Chrome flags and launch parameters using the JSON launch parameter approach, see the Launch Options documentation.

Proxy Configuration and Cost Optimization​

For comprehensive proxy configuration including residential proxies, geographic targeting, and bandwidth cost optimization, see Proxies Documentation.

Production-Ready Error Handling​

For robust error handling patterns including retry logic and proper resource cleanup, see Best Practices for Error Handling.

Regional Optimization​

For regional endpoint optimization and performance considerations, see Best Practices.
