Node.js 설치 및 실행

1. brew를 통해 Node.js 설치 

>>> brew install node
>>> node -v                                                                                                              10:35.30 화  1 11 2022 >>>
v17.3.0
>>> npm -v                                                                                                               10:35.33 화  1 11 2022 >>>
8.3.0

 

2. 간단하게 Node.js 실행해보기 

>>> mkdir ~/projects
>>> cd ~/projects
>>> vi hello-world.js
const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

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

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

>>> node hello-world.js
Server running at http://127.0.0.1:3000/
