A simple script that tells you if a feature is available for a list of browsers

caniuse

#!/usr/bin/env node
  
var browsers = [
  'chrome 49',
  'edge 16',
  'firefox 51',
  'opera 36'
].join(', ');

var caniuse = require('caniuse-api');
switch (process.argv.length) {
  case 3:
    var found = [].concat(caniuse.find(process.argv[2]));
    found.forEach(function (feature) {
      console.log(feature + ': ' + (caniuse.isSupported(feature, browsers) ? '🍾 \x1B[1myup\x1B[0m 🎉' : 'nope'));
    });
    if (found.length < 1) console.log('not at all');
    break;
  default:
    console.log('you need to specify a feature');
}
