Serving Routes

How to serve different routes

Use the app object to define routes for different URLs. Routes are defined using HTTP methods (such as GET, POST, PUT, DELETE, etc.) and specify a callback function that gets executed when a request matches the specified URL and method.

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

// get route
app.get('/', (req, res) => {
  res.send('Hello from GET route!');
});

// post route
app.post('/add', (req, res) => {
  res.send('Hello from POST route!');
});

// PUT route - updation
app.put('/put/:id', (req, res) => {
  res.send('Hello from PUT route!');
});

//DELETE route
app.delete('/delete/:id', (req, res) => {
  res.send('Hello from DELETE route!');
});

app.listen(port, () => {
  console.log(`Server is running on http://localhost:${port}`);
});
