Node.js has become immensely popular over the years as an essential part of many software development projects. It was first released in 2009 by Ryan Dahl who was one of its original contributors (with some help from Douglas Crockford). Node.js is an open-source JavaScript runtime built on Chrome's V8 engine that runs on Linux, Mac OS X, and Windows operating systems. Puppeteer uses the WebDriver protocol to connect with the browser and simulate user interaction with HTML elements or pages. With it, you can run tests in the browser and then see the results in real-time on your terminal. Puppeteer lets you automate the testing of your web applications. It is a tool for automating testing in your application using headless Chrome or Chromebit devices, without requiring any browser extensions like Selenium Webdriver or PhantomJS.

Puppeteer is a Node.js library developed by Google that lets you control headless Chrome through the DevTools Protocol.

In this guide, we'll explore the basics of using Puppeteer with Node.js so you can start automating your tests. You should find Puppeteer executes successfully, provided proper Chrome flags are used.Puppeteer is a JavaScript library that allows you to script and interact with browser windows. Chrome will write into /tmp instead.Īdd your JavaScript to your container with a COPY instruction.

disable-dev-shm-usage – This flag is necessary to avoid running into issues with Docker’s default low shared memory space of 64MB.

If you’re uncomfortable with this, you’ll need to manually configure working Chrome sandboxing, which is a more involved process. It’s vital you ensure your Docker containers are strongly isolated from your host. Using these flags could allow malicious web content to escape the browser process and compromise the host.

no-sandbox and disable-setuid-sandbox – These disable Chrome’s sandboxing, a step which is required when running as the root user (the default in a Docker container).Setting this flag explicitly instructs Chrome not to try and use GPU-based rendering. disable-gpu – The GPU isn’t usually available inside a Docker container, unless you’ve specially configured the host.
