Setdotenv

Simple way to load .env file to process.env object

---

Just use next string in your main file (the file that is loaded first in your project) and there we go!

For typescript

export * from 'setdotenv';
import express from 'express';

For javascript

require('setdotenv');
const express = require('express');

How it works

process.env.NODE_ENV = 'production';
export * from 'setdotenv';

// it reads from production.env file
const myEnv = process.env.MY_ENV;

or

export * from 'setdotenv';

// it reads from development.env file by default
const myEnv = process.env.MY_ENV;

Note

It doesn't read just .env file. Only NODE_ENV.env file.

.env file format

MY_ENV=show must go on
SECRET=my secret key
EXAMPLE=example string
# We can use comments here
NUMBER=123
__TEST=test
@SOME=data
SYMBOLS=@!@!@#$$#%;/23$%$#%%^&

and, then

process.env.MY_ENV === 'show must go on'; // true
process.env.NUMBER === '123'; // true
process.env.__TEST === 'test'; // true
process.env.SOME === 'data'; // true
process.env.SYMBOLS === '@!@!@#$$#%;/23$%$#%%^&'; // true
