Node-Hide environemnt variables in your app

Introduction

This is a question that I been struggle for a long time. However, I final figure it out. There are two ways that I recommend doing this using dotenv package or setting it manually.

dotenv package

Here’s my example repo: dotenv repo

First install dotenv

1	npm install dotenv --save-dev

Create .env file

1	ABC_KEY = 1234qwer

1
2
3

// in server/index.js
require('dotenv').config()
console.log(process.env.ABC_KEY)

Remember in your .gitignore file to ignore .env file.

Set process.env variable in terminal

Second way is to directly set your variable in your terminal and access it in your node.

# type this in your terminal
export ABC_KEY=1234qwer # no space and no quotation
# for window replace export for set
unset ABC_KEY # unset variable

Now you can access the variables in your node app by using process.env.ABC_KEY
