Using a framework like express.js can provide a more organized and efficient way of handling routing and server setup. It offers features like middleware, routing, and error handling out of the box, which can simplify development and improve code maintainability.

Basic Routing

app.METHOD(PATH, HANDLER)

• app is an instance of express.
• METHOD is an HTTP request method, in lowercase.
• PATH is a path on the server.
• HANDLER is the function executed when the route is matched.

GET

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

POST

app.post('/', (req, res) => {
  res.send('Got a POST request')
})

PUT

app.put('/user', (req, res) => {
  res.send('Got a PUT request at /user')
})

DELETE

app.delete('/user', (req, res) => {
  res.send('Got a DELETE request at /user')
})
