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.
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
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.
require('dotenv').config(); console.log(process.env.package_version); // 1.2.4
Note: Install the
dotenvnpm package, if you don’t have in your project.
