CorsEnv

Corsenv is a zero-dependency module that loads environment variables from a .env file into process.env. Storing configuration in the environment separate from code is based on The Twelve-Factor App methodology.

Install

install locally (recommended) npm install cors-env --save Or installing with yarn? yarn add cors-env

Usage

Usage is easy!

1. Create a .env file in the root directory of your project. .env file

   Add environment-specific variables on new lines in the form of NAME=VALUE

   DB_HOST=localhost

   DB_USER=root

   DB_PASS=s1mpl3

2. As early as possible in your application, import and configure dotenv. // index.js require('cors-env').config()

   console.log(process.env) // remove this after you've confirmed it working

   .. or using ES6?

   // index.mjs (ESM) import 'dotenv/config'; import express from 'express';

3. That's it! 🎉

   process.env now has the keys and values you defined in your .env file.

   require('cors-env').config()

   ...

   const db = require('db') db.connect({ host: process.env.DB_HOST, username: process.env.DB_USER, password: process.env.DB_PASS })
