What are some effective error handling tips for Puppeteer?

When using Puppeteer, it's crucial to handle errors gracefully. Here are some tips: 1. Use try-catch blocks around your async functions. 2. Implement proper logging to capture errors. 3. Use page.on('error') and page.on('pageerror') to catch errors in the browser context.

Can you give an example of using try-catch in Puppeteer?

Sure! Here's a simple example:

try {
  await page.goto('https://example.com');
} catch (error) {
  console.error('Navigation failed:', error);
}

What should I log when an error occurs?

You should log the error message, stack trace, and any relevant context, such as the URL you were trying to access or the action being performed.

How can I handle timeouts in Puppeteer?

You can set a timeout for navigation and other actions using the timeout option. For example:

await page.goto('https://example.com', { timeout: 30000 });
``` This will throw an error if the navigation takes longer than 30 seconds.
