How to automatically retry failed network requests in Puppeteer?

You can automatically retry failed network requests in Puppeteer by using the page.on('requestfailed') event listener. Here is an example code snippet that demonstrates how to implement automatic retry logic for failed network requests in Puppeteer:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  let retryCount = 0;
  const maxRetries = 3;

  page.on('requestfailed', async (request) => {
    if (retryCount < maxRetries) {
      retryCount++;
      console.log(`Retrying request: ${request.url()} - Retry #${retryCount}`);
      await request.continue();
    } else {
      console.error(`Max retries reached for request: ${request.url()}`);
    }
  });

  await page.goto('https://example.com');
  
  // Other Puppeteer actions and scripts here

  await browser.close();
})();

In this code snippet, we create a new Puppeteer page and set up an event listener for the requestfailed event. When a network request fails, the event listener will be triggered, and we can check if we still have remaining retries to make. If there are retries left, we increment the retryCount and continue the failed request by calling request.continue(). If we have reached the maximum number of retries specified in maxRetries, we log an error message.

You can customize the retry logic further by adding conditions or changing the behavior based on the specific requirements of your project.
