NodeJS Dot Environments

This library exports all pairs (key=value) from .env-file to process.env-object. This makes it very easy to configure your application using the environment variables.

Install

$ npm i node-dotenv

Usage

"use strict";

const dotEnv = require('node-dotenv')(); //It's enough

// or with an explicit file path
dotEnv = require('node-dotenv')('../file/path/to/.env'); //It's enough

//if you want get all vars from .env
dotEnv.then(envVars => console.log(envVars));

File path to .env

.env-file search stage (places):

1. parameter passed in the call module;
2. value from environment variable NODE_DOT_ENV_PATH;
3. in root directory of your project;
4. as a result of call dirname(require.main.filename).

Example .env-file structure:

varName1=varVal1
varName2=varVal2

varName3=varVal3
...
varNameN=varValN
...

Comments in .env

You can commented some strings of .env-file like follow:

varName1=varVal1
#varName2=varVal2
varName3=varVal3

String started with # will not be parse.
