Capture a screenshot of url, returns a Promise which resolves with a buffer.

  • format File format (png, jpg, bmp)

screenshot.stream(options)

  .stream({
    url: 'https://github.com/',
    width: 800,
    height: 600
  })
  .pipe(fs.createWriteStream(`${__dirname}/example-stream.png`))
  .on('close', () => console.log('open example-stream.png'))

Installation

With npm do:

npm install capture-electron

CI

This project requires an xvfb setup to be running in your CI environment. For an example how to set one up, check out the .travis.yml. After that, no further setup is required however, as the electron executable is installed automatically.
