write PORT in .env file in backend folder

PORT = <PORT_NUMBER>

For Ex.

PORT = 3000

Install dotenv in backend folder

npm i dotenv

Import dotenv in server.js file

require('dotenv').config()

or set .env path in

require("dotenv").config({path: "./back-end/.env"});

Then Check by:

console.log(process.env);

Run in backend folder

node server.js

You can specify the path where the .env file is to dotenv package.

Please modify the following line of code to

require("dotenv").config();

like this:

require("dotenv").config({path: "./back-end/.env"});

To use DotEnv, first install it using the command: npm i dotenv . Then in your app, require and configure the package like this: require('dotenv'). config()

    require('dotenv').config();

console.log(process.env.MY_ENV_VAR);
