Could not access windows environment variable in Node

Today I was trying to write an environment variable like this:

set PORT=5000

But when I access it through the process.env.PORT variable in node, it gives undefined.

I might be missing something or my PC is malfunctioning, so any help would be appreciated, Thanks

use the below command to set the port number in node process while running node JS program. And this port will only limited to this node process.

set PORT =3000 && node file_name.js

The set port can be accessed in the code as

process.env.PORT

I recommend you using .environment file to keep your configuration separate.

Steps to follow:

  • create a package.json file
  • install the dotenv npm package
  • write the code to read the .env
  • run the code

.env

# .env.example
NODE_ENV=development
PORT=8626
# Set your database connection information here 
API_KEY=your-core-api-key-goes-here

server.js file:

// server.js
console.log(`Your port is ${process.env.PORT}`); // undefined
const dotenv = require('dotenv');
dotenv.config();
console.log(`Your port is ${process.env.PORT}`); // 8626
