expressjsHow do I use Express.js with W3Schools?


Express.js is a web application framework for Node.js, allowing developers to create dynamic web applications. Express.js can be used with W3Schools to create a web application that can be accessed by users.

Below is an example of how to use Express.js with W3Schools:

var express = require('express');
var app = express();

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

app.listen(3000);

The code above creates an Express.js application that listens on port 3000. When a request is made to the root path (/), the response will be Hello World!.

Code explanation

  1. var express = require('express'); - This line imports the Express.js module.
  2. var app = express(); - This line creates an Express.js application.
  3. app.get('/', function (req, res) { - This line creates a route handler for the root path (/).
  4. res.send('Hello World!'); - This line sends the response Hello World! when the root path is requested.
  5. app.listen(3000); - This line starts the Express.js application and listens on port 3000.
