How can I prevent puppeteer from freezing while processing multiple URLs, and efficiently skip any URLs that time out and move on to the next one in the list?

There are a few strategies you can use to prevent Puppeteer from freezing while processing multiple URLs and efficiently skip any URLs that time out:

  1. Use asynchronous code: Since Puppeteer operations are asynchronous, it's best to use async/await or promise chains to ensure that your code runs efficiently. This will allow you to handle any timeouts or errors without freezing your code.

  2. Use the timeout option: When navigating to a URL with Puppeteer, you can set a timeout option to prevent the page from hanging indefinitely. If the page takes too long to load or process, Puppeteer will throw an error that you can catch and handle accordingly.

  3. Implement retries: If an URL times out or fails to load, you can implement retries to increase the chance of success. This can be done by adding a loop that tries the URL multiple times with a delay in between. If the URL still fails to load after a certain number of tries, you can move on to the next URL.

  4. Use parallel processing: If you have a large number of URLs to process, you can use parallel processing to speed up the process. This can be done by using Promise.all to launch multiple instances of Puppeteer at the same time.

Overall, handling timeouts and errors efficiently is key to preventing Puppeteer from freezing and ensuring that your code runs smoothly. By using these strategies, you can process multiple URLs with Puppeteer without running into issues.
