Template engines in Express

 Template engines in Express: Template engines in Express allow you to dynamically generate HTML pages. You can use a variety of template engines, such as Handlebars, EJS, and Pug. Here's an example of how to use the Handlebars template engine in Express:

javascript

const express = require('express');

const exphbs = require('express-handlebars');

const app = express();

app.engine('handlebars', exphbs());

app.set('view engine', 'handlebars');

app.get('/', (req, res) => {

  const data = { name: 'John' };

  res.render('home', data);

});

app.listen(3000, () => {

  console.log('Server listening on port 3000');

});

In this example, the home.handlebars template will be rendered with the data object. The exphbs function creates an instance of the Handlebars template engine, which is then set as the view engine for the app using the app.set method.
