In this post we will look at leveraging Chrome’s debug protocol to load up a webpage and take a screenshot. This is all made possible from a package called chromedp which allows us to control a Chrome instance through our code. You will also need Chrome installed or to be using something akin to the chrome/headless-shell docker image.

We’ve split the process in code up into:

  • Start Chrome
  • Run tasks: like loading the webpage and taking a screenshot
  • Saving the screenshot to file
