Puppeteer is a Node library that provides a high-level API to control Chrome or Chromium browsers through the DevTools Protocol. Puppeteer allows you to automate tasks in a headless browser environment.

When using Puppeteer, you may encounter situations where you want to skip downloading certain types of resources, such as images or stylesheets. Skipping the download of unnecessary resources can help improve the performance and speed of your automation script.

How to Skip Downloading Resources using Puppeteer

Puppeteer provides a couple of options to control the resource types that should be skipped during navigation or request interception. These options are:

  • request.resourceType(): This method allows you to specify the types of resources that should be intercepted or skipped during request interception. You can exclude resource types such as images, stylesheets, fonts, scripts, etc.
  • request.abort(): This method allows you to abort the request for a particular resource when it matches certain conditions, such as a specific URL or resource type.

Here’s an example of how you can use Puppeteer to skip downloading images:

const puppeteer = require('puppeteer');
  
  (async () => {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    
    await page.setRequestInterception(true);
    
    page.on('request', (request) => {
      if (request.resourceType() === 'image') {
        request.abort();
      } else {
        request.continue();
      }
    });
    
    await page.goto('https://example.com');
    
    // Continue with the rest of your automation script
    
    await browser.close();
  })();

In the above example, we set up request interception on the page by calling page.setRequestInterception(true). Then, in the request event listener, we check if the resource type of the request is ‘image’ using request.resourceType(). If it is an image, we abort the request using request.abort(). Otherwise, we continue with the request by calling request.continue().

By using this approach, the browser will skip downloading all the images on the page, resulting in faster automation script execution and reduced network traffic.
