In this article, we would like to show you how to use and execute packages installed with npm in Node.js.

1. Install example npm package

npm install dotenv

Note:

This command is going to install the package in the local node_modules folder.

2. After you install a package using npm, you need to import it inside your project.

const dotenv = require('dotenv');

3. Now you can work with the variable you assigned the package to.

const dotenv = require('dotenv');

// example usage of the npm package
dotenv.config();
