Clearing the browser cache in Puppeteer involves using thepage.setCacheEnabled() method and clearing specific types of data, such as cookies, local storage, or service workers. Here's a detailed explanation of how to clear the browser cache 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. Clearing the cache usingpage.setCacheEnabled(): To clear the browser cache, you can use thesetCacheEnabled() method on the page instance. Set the cache enabled parameter tofalse to disable caching.

   await page.setCacheEnabled(false);

This code disables caching in Puppeteer by settingsetCacheEnabled(false) on the page instance. 3. Clearing cookies: To clear cookies, you can use thepage.deleteCookie() method to delete cookies individually or thepage.deleteCookies() method to delete all cookies.

   // Delete a specific cookie by name
   await page.deleteCookie({ name: 'your-cookie-name' });

   // Delete all cookies
   await page.deleteCookies();

4. Clearing local storage and session storage: To clear local storage and session storage, you can usepage.evaluate() to execute JavaScript code that clears the storage.

   // Clear local storage
   await page.evaluate(() => {
     localStorage.clear();
   });

   // Clear session storage
   await page.evaluate(() => {
     sessionStorage.clear();
   });

5. Clearing service workers: To clear service workers, you can usepage.unregisterServiceWorker() to unregister a specific service worker orpage.unregisterServiceWorkers() to unregister all service workers.

   // Unregister a specific service worker by scope URL
   await page.unregisterServiceWorker({ scopeURL: 'your-service-worker-scope' });

   // Unregister all service workers
   await page.unregisterServiceWorkers();

By following these steps, you can clear the browser cache in Puppeteer. Disabling the cache usingsetCacheEnabled(false) prevents caching of network resources. You can also clear specific types of data, such as cookies, local storage, or service workers, using the appropriate methods provided by Puppeteer. This allows you to control and manage the browser cache according to your testing or scraping needs.
