Sniff

The gluegun requires a Node 7.6.0 environment which provides async and await support natively.

You can safely check these requirements by using the sniff module.

const { ok } = require('gluegun/sniff')

if (ok) {
  // we are clear for lift-off
}

The ok property will be true if everything is good to go.

sniff also has a few more properties you can use for better errors.

property	type	value
ok	bool	true if everything is good to go
isNewEnough	bool	true if we have Node.js >= 7.6.0
hasAsyncAwait	bool	true if we have --harmony enabled
nodeVersion	string	the node version such as '7.6.0'
nodeMinimum	string	the node minimum that sniff is looking for

These two properties will both be set to true if we're running in Node 7.6.0.
