how to use

const isEnv = require('is-node-env')()

then NODE_ENV=development node index.js

console.log(isEnv.development) // true

or pass your own envs

const isEnv = require('node-is-env')({ dev: 'development' });

NODE_ENV=production node index.js

console.log(isEnv.dev); // false

Inbuilt strings: 'development', 'testing', 'production', 'staging'

why

I got tired of testing my node envs by typing process.env.NODE_ENV

also, isEnv.development / isEnv.production is more readable than process.env.NODE_ENV === 'production'
