Here’s an implementation to use Puppeteer to control Headless Chrome and navigate to a website: // Filename: server.jsĪpp. codecount sokrates Clone Clone with SSH Clone with HTTPS Open in your IDE Visual Studio Code. In fact, it can all be done in a headless mode. Docker Puppeteer is a container image with the recommended configuration for using Puppeteer to drive a headless Chrome browser (from the Puppeteer project). Most importantly, Puppeteer doesn’t require a running GUI. You can test your UI on different device simulations and take screenshots. Puppeteer is a Node.js library that provides a high-level API to control Chrome or Chromium over the Chrome DevTools Protocol. You can use the Puppeteer library to use Headless Chrome with Node.js.
This library uses WebSocket or a system pipe-based protocol over a Chrome DevTools interface, which can take screenshots, and measure page load metrics, connection speeds, downloaded content size, and more. Node.js is the main language interface used by the Google Chrome development team, and it has an almost native integrated library for communicating with Chrome called Puppeteer. Headless Chrome inside a Docker container.In this tutorial, we’ll demonstrate how to create a Dockerfile to set up a Headless Chrome browser in Node.js. It has become increasingly critical to have a Docker container-based headless browser to maximize flexibility and scalability. Running a GUI is more expensive than spinning up a Linux-based server or scaling a simple Docker container across a microservices cluster, such as Kubernetes.īut I digress. There are also countless use cases for website crawlers and HTML-based content analysis.įor 99 percent of these cases, you don’t need a browser GUI because it is fully automated. Headless browsers have become very popular with the rise of automated UI tests in the application development process. To learn more about Docker, visit our archives here.
