node-feature-detect

Checks for features.

var detect = require('node-feature-detect')

detect.features
// [ 'generators', 'let', 'fat arrow', ... ]

detect('class', 'generators')
// { unsupported: 'class', minVersion: '4.0.0' }

or:

var unsupported = detect('let')
if (unsupported) {
  // ...
}

Or you can automatically fail:

detect.fail('class', 'generators')

// Error: Your platform doesn't support these features: generators, class.
// Please upgrade to Node.js v4.0.0 or above.
