Extract all frames of a gif to their respective images

extractFrames.js

// Quick and dirty script that I'll only use once...
// Grabs all the frames in a gif and write them to individual files
//
// Example
// node extractFrames.js --gif path/to/gif

const gifFrames = require('gif-frames');
const argv = require('yargs').argv
const fs = require('fs');

gifFrames(
  { url: argv.gif, frames: 'all', outputType: 'png', cumulative: true },
  function (err, frameData) {
    if (err) {
      throw err;
    }
    frameData.forEach(function (frame) {
      frame.getImage().pipe(fs.createWriteStream(
        `${basename(argv.gif)}-${frame.frameIndex}.png`
      ));
    });
  }
);

// Helper
function basename(path) {
   return path.split('/').reverse()[0].split('.')[0];
