To wait for all downloads to complete with Puppeteer using request interception, you can use the request event to intercept all network requests made by the browser and track when they are finished. A headless browser is a web browser, without a graphical user interface, that is mainly used for automated testing. It can also be configured to use full (non-headless) Chrome or Chromium. Finally, we close the browser instance.īy using the download event, we can wait for all downloads to complete with Puppeteer in a reliable and efficient way. Puppeteer is a Node library that provides a high-level API to control headless Chrome or Chromium browsers over the DevTools Protocol. We then navigate to the page that initiates the download and wait for all downloads to complete using the waitForDownload method. We add a listener to the download event to log when a download is completed. The download event is emitted by the browser context when a download initiated by the page is completed. We then set the download behavior for the page to allow downloads and specify the download path. Method 1: Using the download event You can use the download event to wait for all downloads to complete with Puppeteer. In this code, we first create a new browser instance using Puppeteer and a new page. 1.20.0 Platform / OS version: Linux, 64bit, Ubuntu 19.10 URLs (if applicable): (the chromium artifact being downloaded) Node.js version: v12.16.1, v12.16.0, v12.13. Check out system requirements for details. Headless execution is supported for all browsers on all platforms. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast. It allows testing Chromium, Firefox and WebKit with a single API. Const puppeteer = require ( 'puppeteer' ) const browser = await puppeteer. Playwright is a framework for Web Testing and Automation.
