Facebook Post Capture

An automated way to take a fullscreen capture (iPhone 6 viewport simulated) of a facebook post with all its comments

Requirements

  • Node >= 7
  • Facebook user credentials

Authentication

You can either pass your facebook username FB_USER and password FB_PASSWORD (and eventually the private key FB_2FA_KEY for the TOTP code generator if you have 2FA enabled) as environment variables (recommanded) or as arguments in the command line. Those credentials are required for this script to work!

Usage

CLI Arguments:
    --url (required)    Permanent link of the facebook post
    --format            jpeg or png. Default: png
    --quality           Quality of the result (number). Default: 100
    --stitch            Stitch all the separated parts into a single screenshot. Default: false
    --maxHeight         Max height of each screenshot. If --stitch is set, this value will be 16384. Default: 16384
    --outputDir         Output directory. Default: './'
    --outputName        Output filename. Default: 'screenshot'
    
    --anonymous         Hide the identity of all involved users (Replace usernames by their abbreviations and blur their profile pictures). Default: false

    --fbuser            This takes precedence over the env variable FB_USER
    --fbpassword        This takes precedence over the env variable FB_PASSWORD
    --fb2fakey          This takes precedence over the env variable FB_2FA_KEY

Example:

Taking screenshot of a New York Times's post and save it to a single file in jpeg format, 70% quality and hide the identity of all involved users:

$ ./fb.js --fbuser "user@email.com" --fbpassword "secret" --fb2fakey "AAAA BBBB CCCC DDDD" --url "https://m.facebook.com/story.php?story_fbid=10151276647049999&id=5281959998" --anonymous --format jpeg --quality 70 --stitch

Result:
