In this guide, we'll explore the basics of using Puppeteer with Node.js so you can start automating your tests. child.jsĬonsole.log("CHILD: url received from parent process", url) Īwait page._nd('Page.Puppeteer is a JavaScript library that allows you to script and interact with browser windows. For every URL a replacement child thread is going to be initiated. During this file we initiate our child processes and send the URL of the pictures we would like to download. We have two files during this solution, the primary one is main.js. const puppeteer = require('puppeteer') Ĭonst downloadPath = path.resolve('./download') Īwait page._nd('tDownloadBehavior', `) Let’s update our script to line the trail.

We can avoid the default download path by explicitly specifying the trail in our script. Finally, we are using the click() function to simulate the button click. Then we are opening up a replacement tab with the given URL. We are creating a replacement instance of Puppeteer. This may allow us to watch the automation in real-time. The headless option is about to be false. We can use the subsequent script to automate the download process Finally, we’ll click on the download button.

Then we’ll find the download button on the page. we’ll open up a URL during a new browser tab.
