Answer 1

I've noticed this happening several times for me when I used ngx-rocket to scaffold a new project. For some reason it seemed to miss part of the script.

Anyways it was easily fixed by running this command at the same root level as your app:

npm run env

Then build your app and run it, that should solve the problem.

You can use dotenv it is easy to use and it can help you get the .env file with all the variables that are inside. It can be something like:

/yourfile.env

NAME=YOUR_NAME

/index.js

require('dotenv').config({path: 'yourfile.env'}
console.log(process.env.NAME) //YOUR_NAME

Answer 3

With module js (.mjs) you do:

Install dotenv module. Yarn: yarn dotenv or Npm: npm i dotenv

import dotenv from 'dotenv'
# all imports...
dotenv.config()
