Express 'Hello World'

 

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})

 

http://localhost:3000/

 

 

*comment

app.get('/') ->  app.get('/node') 수정하면

 

http://localhost:3000/node 에서 열린다.
