What is npm?

npm makes it easy for JavaScript developers to share and reuse code, and makes it easy to update the code that you’re sharing, so you can build amazing things.

Install npm

npm is installed with Node.js

npm is distributed with Node.js- which means that when you download Node.js, you automatically get npm installed on your computer.

Download Node.js and npm

Check that you have node and npm installed

To check if you have Node.js installed, run this command in your terminal:

node -v

To confirm that you have npm installed you can run this command in your terminal:

npm -v

A note on versions

npm versions

npm is a separate project from Node.js, and tends to update more frequently. As a result, even if you’ve just downloaded Node.js (and therefore npm), you’ll probably need to update your npm. Luckily, npm knows how to update itself! To update your npm, type this into your terminal:

npm install npm@latest -g

Node versions and Long Term Support

Node.js has lots of versions! To use Node.js, and therefore npm, effectively, you’ll want to make sure that you are on a version that is supported by the Node.js team. In general, you should use the version of Node.js labelled “LTS”.

Use a Node.js version manager

Software is always changing, and so it’s often a good practice to use a version manager to help account for this change. For this reason (and many others!) we recommend that you use a version manager for your Node.js installation. There are many great options; here are a few*:
