Getting the version number from package.json in Node.js

In this tutorial, we are going to learn about two different ways to get the version number from a package.json file in the Node app.

Getting the version number

We can get the version number from the package.json file by requiring it as a module.

Here is an example:

const package_json = require('./package.json');

console.log(package_json.version); // 1.2.4

The package_json.version property is holding the version number.

Similarly, we can also access the version number by saved it inside the .env file and accessing it using the environment variable.

package_version=1.2.4

require('dotenv').config();

console.log(process.env.package_version); // 1.2.4

Note: Install the dotenv npm package, if you don’t have in your project.
