Check Node.js Version

Whether you're a developer setting up a new project, troubleshooting compatibility issues, or just ensuring the development environment is up-to-date, knowing the Node.js version is an important step. Different projects or dependencies often require specific versions of Node.js, and having this information at your fingertips can save you time. This tutorial explains how to check Node.js version.

1. 'version' option

The easiest and most common way to check the Node.js version is by using the command line option version (or the -v shortcut):

node --version

node -v

Output example:

v20.6.1

2. 'process.version' property

Within the Node.js application, you can use the process.version property:

const version = process.version;
console.log(version);

3. 'process.versions.node' property

Another way to fetch the Node.js version programmatically is through the process.versions.node property. It specifically returns the Node.js version without the leading "v".

const version = process.versions.node;
console.log(version);
