expressjsHow do I use Express.js and Jade together to create a web application?

Express.js and Jade can be used together to create a web application. Express.js is a Node.js web application framework that provides a robust set of features for web and mobile applications. Jade is a templating language for Node.js that is used to generate HTML markup.

The following example code shows how Express.js and Jade can be used together to create a web application:

// Require Express.js
var express = require('express');

// Create an Express.js application
var app = express();

// Set view engine to Jade
app.set('view engine', 'jade');

// Create a route for the application
app.get('/', function (req, res) {
  // Render a Jade view
  res.render('index');
});

// Start the server
app.listen(3000);

This code will create a web application that will render a Jade view when the root route is accessed.
