Define env vars in a file

  1. Create an .env file
  2. Use dotenv package.

.env file content

for example:

.env

NISIM=bamba
SHLOMO=avi biter
DAVID=42

console.log(process.env.NISIM); // undefined
console.log(process.env.SHLOMO); // undefined
console.log(process.env.DAVID); // undefined

Why undefined?

having .env file is not enough.

you also have to:

  • install dotenv package.
  • import package.
  • run config method.

dotenv package

install

npm install dotenv

index.js

require('dotenv').config();

console.log(process.env.NISIM); // 'bamba'
console.log(process.env.SHLOMO); // 'avi biter'
console.log(process.env.DAVID); // '42'
console.log(typeof process.env.DAVID); // 'string'

so we should have something like this

.env

SECRET=123
