Handling AJAX requests in Puppeteer involves using thepage.waitForResponse() orpage.waitForRequest() methods to wait for specific network requests to complete. Here's a detailed explanation of how to handle AJAX requests in Puppeteer: 1. Launching a new browser instance and creating a new page:

   const puppeteer = require('puppeteer');

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

     // Perform actions with the page here

     // Close the browser
     await browser.close();
   })();
   

This code sets up a basic Puppeteer script. It launches a new headless browser instance and creates a new page to work with. 2. Handling AJAX requests withpage.waitForResponse(): Thepage.waitForResponse() method allows you to wait for a specific network response based on various criteria such as URL, status code, or response headers.

   const response = await page.waitForResponse((response) => {
     return response.url().includes('your-ajax-url');
   });
   

In this example,page.waitForResponse() is used to wait for a network response that matches the specified condition. The condition is defined using a callback function that checks if the response URL includes'your-ajax-url'. The method returns a response object that you can use for further processing or validation. 3. Handling AJAX requests withpage.waitForRequest(): If you want to wait for a specific network request to be initiated, you can use thepage.waitForRequest() method. Similar topage.waitForResponse(), you can define a condition to match the request based on URL, method, headers, etc.

     return request.url().includes('your-ajax-url');
