How to install Node.js and npm on a Mac using Homebrew

Homebrew is a package manager for macOS. This guide will help you install Node.js and npm using a Homebrew formula.

You will need to have Homebrew installed. For the instructions on how to install Homebrew, head over here.

Step 1. Update Homebrew


brew update

It is recommended that you always update Homebrew before installing new formulae. Homebrew will also try to update automatically every time you install new formulae, but you can disable that by setting HOMEBREW_NO_AUTO_UPDATE=1.

Step 2. Install Node.js


brew install node

npm will be installed together with Node.js.

Step 3. Check your installation



This will open the Node.js REPL. Execute a sample script, e.g.

function fib(n) {
    if (n < 3) {
        return 1

    return fib(n - 1) + fib(n - 2)
