Headless Chrome is shipping in Chrome It's a way to run the Chrome browser in a headless environment. Essentially, running Chrome without chrome! It brings all modern web platform features provided by Chromium and the Blink rendering engine to the command line. A headless browser is a great tool for automated testing and server environments where you don't need a visible UI shell. For example, you may want to run some tests against a real web page, create a PDF of it, or just inspect how the browser renders an URL.

The easiest way to get started with headless mode is to open the Chrome binary from the command line. The exact location will vary from platform to platform.

If you're on the stable channel of Chrome and cannot get the Beta, I recommend using chrome-canary :. In some cases, you may not need to programmatically script Headless Chrome. There are some useful command line flags to perform common tasks. The --dump-dom flag prints document. To capture a screenshot of a page, use the --screenshot flag:.

Running with --screenshot will produce a file named screenshot. If you're looking for full page screenshots, things are a tad more involved. There's a great blog post from David Schnurr that has you covered. Check out Using headless Chrome as an automated screenshot tool. The --repl flag runs Headless in a mode where you can evaluate JS expressions in the browser, right from the command line:.

If you're using Headless programmatically, this page is also a powerful debugging tool for seeing all the raw DevTools protocol commands going across the wire, communicating with the browser.

Getting Started with Headless Chrome

Puppeteer is a Node library developed by the Chrome team. It provides a high-level API to control headless or full Chrome. It's similar to other automated testing libraries like Phantom and NightmareJS, but it only works with the latest versions of Chrome.

Among other things, Puppeteer can be used to easily take screenshots, create PDFs, navigate pages, and fetch information about those pages. I recommend the library if you want to quickly automate browser testing. It hides away the complexities of the DevTools protocol and takes care of redundant tasks like launching a debug instance of Chrome. Check out Puppeteer's documentation to learn more about the full API.

I recommend it if you want to be close to the metal and use the DevTools protocol directly. However, to fully automate tests, you'll probably want to spawn Chrome from your application.

But things get tricky if you want a portable solution that works across multiple platforms. Just look at that hard-coded path to Chrome :. Lighthouse is a marvelous tool for testing the quality of your web apps. A robust module for launching Chrome was developed within Lighthouse and is now extracted for standalone use. The chrome-launcher NPM module will find where Chrome is installed, set up a debug instance, launch the browser, and kill it when your program is done.

Best part is that it works cross-platform thanks to Node!By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Those channels are:. Chrome Stable is the mainstream release that most users have. Its features are tried and tested, and it hardly ever crashes. The trade-off is more new features, sooner.
