process.env is undefined after using .env file in node.js

Question

I have created an application using node.js & protractor. the following start script is used in the package.json file for running my application

"start": "protractor conf/conf.js"

I have created a .env file and add one sample variable TestManaf='1234556' But it shows error like 'the value is undefined'.

After this, I have directly added TestManaf='1234556' in the start script.

"start": "set TestManaf='1234556' && protractor conf/conf.js"

It is working fine. Why .env file not supported? is any additional configuration required?

are you writing at any time to the proccess.env? this package takes care of it: npmjs.com/package/dotenv — Argee

You need to install the package dotenv

use the following command:

npm install dotenv

First thing you should do in your file is load the dotenv env vars, put this line as soon as possible in your import hierarchy.

require('dotenv').config()

You can see more information about using this package in the documentation
