How can I take a screenshot of the entire screen in Node JS?

How can I take a screenshot of one monitor / screen in Node JS? What libraries do I need and how do I use them? It needs to be able to successfully write to a file the contents of the entire monitor.

I can't seem to find anything but how to take screenshots of webpages, or specific windows. Thanks for helping!

Solution

  • You can try the screenshot-desktop npm module. It's cross platform (Linux, Mac, Windows) and can save directly to a file.

    Install:

    $ npm install --save screenshot-desktop

    Use:

    const screenshot = require('screenshot-desktop')

screenshot({ filename: 'shot.jpg' }).then((imgPath) => {
  // imgPath: absolute path to screenshot
  // created in current working directory named shot.png
});

// absolute paths work too. so do pngs
screenshot({ filename: '/Users/brian/Desktop/demo.png' })
