How do you define a route in Express?

Question

Ravi Vishwakarma · Answer

In Express (a Node.js web framework), you define a route using methods like 
app.get(), app.post(), app.put(), etc., depending on the HTTP verb you want to handle.
Here’s the basic syntax:
const express = require('express');
const app = express();
// Define a route
app.get('/example', (req, res) =andgt; {
  res.send('This is the /example route!');
});
// Start the server
app.listen(3000, () =andgt; {
  console.log('Server is running on port 3000');
});
and 
Breakdown:
app.get() defines a GET route.
The first argument ('/example') is the route path.
The second argument is a callback function (called a route handler) with
req (request) and res (response) parameters.
res.send() sends a response to the client.
and 
Other common HTTP methods:
app.post('/submit', (req, res) =andgt; { ... });
app.put('/update/:id', (req, res) =andgt; { ... });
app.delete('/delete/:id', (req, res) =andgt; { ... });
