is-not-production

Detect if you are NOT in the production mode of the nodejs.

Simply, it checks process.env.NODE_ENV !== 'production'.

Install

npm install is-not-production --S

Usage

import isNotProduction from 'is-not-production';

if (isNotProduction) {
  throw new Error('You are should be in the production mode to stay alive');
}

isNotProduction is a constant, defined at the moment of script initialize. Typically, the value of NODE_ENV does not change through runtime. But still if you want to be sure, use isNotProductionRuntime() fn to get isNotProduction state at the current moment.

// process.env.NODE_ENV == 'production'
import isNotProduction from 'is-not-production';
import isNotProductionRuntime from 'is-not-production/runtime';

console.log(isNotProduction); // false

process.env.NODE_ENV == 'development';
console.log(isNotProduction); // false
console.log(isNotProductionRuntime()); // true
