npm install env-isenv-is
=====================
Simple module to test if current NODE_ENV is or is not within a list of allowed environments
It is simple as:
``js
// for env = development
var env = require('env-is');
console.log(env.is('production')); // true if NODE_ENV is production
console.log(env.is(['production', 'staging'])); // true if NODE_ENV is production or staging
console.log(env.isNot('production')); // true if NODE_ENV is NOT production
console.log(env.isNot(['production', 'staging'])); // true if NODE_ENV is NOT production or staging
`
The return value of env.is will change depending on the value of NODE_ENV
`
NODE_ENV=production node app
Will return:js
console.log(env.is('production')); //true
console.log(env.is(['production', 'staging'])); //true
console.log(env.isNot('production')); //false
console.log(env.isNot(['production', 'staging'])); //false
`
And
NODE_ENV=staging node app
Will return:js
console.log(env.is('production')); //false
console.log(env.is(['production', 'staging'])); //true
console.log(env.isNot('production')); //true
console.log(env.isNot(['production', 'staging'])); //false
`
And...
NODE_ENV=development node app
Will returnjs
console.log(env.is('production')); //false
console.log(env.is(['production', 'staging'])); //false
console.log(env.isNot('production')); //true
console.log(env.isNot(['production', 'staging'])); //true
