Install NPM and Node.js

On a Home Computer

This installation only needs to be done once.

In order to use Vite, you'll need to install Node.js and NPM. NPM is a package manager for JavaScript. Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a browser.

If you don't install Node.js, which also installs NPM, you'll get an error when you try to run npm create vite@latest. It will say something like npm : The term 'npm' is not recognized.

Go to and download the latest version of Node.js. When you install Node.js, it will also install NPM.

If you still have issues after installation, follow these instructions for Windows.
