expressjsHow do I use Express.js to create the next route?
Express.js is a web application framework for Node.js used to create web applications and APIs. To create a route using Express.js, you need to first require the Express module, create an Express application, and then use the app.METHOD()
function to create the route.
For example, to create a GET route for the path /example
, you would use the following code:
const express = require('express');
const app = express();
app.get('/example', (req, res) => {
res.send('This is an example route!');
});
The output of the code above would be This is an example route!
when a GET request is made to /example
.
