Installation Guide

If Terminal is not already open, follow these steps:

1. Press Command (⌘) + Space to open Spotlight Search.
2. Type Terminal.
3. Press Return to launch it.

Keep the Terminal window open for the next phases.

If you don't have Homebrew installed yet, install it first:

echo 

Then install Node.js:

1. Copy the installation command below.
2. Paste it into your Terminal window.
3. Press Return to execute it.
4. Enter your administrator password if prompted.

Run the following commands in Terminal to confirm Node.js and npm are installed correctly:

1. Type node --version and press Return.
2. Type npm --version and press Return.

node --version
npm --version

You should see version numbers printed for both commands, for example:

v24.14.1
10.9.2

Create a simple test file to make sure everything works:

1. Create a new file called hello.mjs with the code below.
2. Run node hello.mjs in Terminal.
3. Open http://127.0.0.1:3000 in your browser.

import { createServer } from 'node:http';

const server = createServer((req, res) => {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World!\n');
});

server.listen(3000, '127.0.0.1', () => {
  console.log('Listening on http://127.0.0.1:3000');
});

node hello.mjs

You should see "Hello World!" displayed in your browser.
