This makes it easier to build web pages that display data from your server.<\/p>\n<p>A template engine is a tool that lets you create HTML pages with dynamic content using placeholders and logic.<\/p>\n<p><strong>How Template Engines Work<\/strong><\/p>\n<ol>\n<li>The server receives a request.<\/li>\n<li>Express renders a template file (like .ejs, .pug, or .hbs).<\/li>\n<li>The placeholders inside the template are replaced with real data.<\/li>\n<li>The final HTML page is sent to the client.<\/li>\n<\/ol>\n<p><strong>Common Template Engines for Express<\/strong><\/p>\n<p><strong>1. EJS (Embedded JavaScript)<\/strong><\/p>\n<ul>\n<li>EJS (Embedded JavaScript)<\/li>\n<li>Looks similar to normal HTML.<\/li>\n<li>Uses &lt;%= %&gt; for embedding JavaScript variables.<br \/>\nExample: &lt;h1&gt;Hello &lt;%= name %&gt;&lt;\/h1&gt;<\/li>\n<\/ul>\n<p><strong>Express setup:<\/strong><\/p>\n<pre><code>app.set('view engine', 'ejs');<\/code><\/pre>\n<p><strong>2. Pug (formerly Jade)<\/strong><\/p>\n<ul>\n<li>Uses indentation instead of HTML tags.<\/li>\n<li>Cleaner and shorter syntax.<\/li>\n<li>Example:<br \/>\nh1 Hello #{name}<\/li>\n<\/ul>\n<p><strong>Express setup:<\/strong><\/p>\n<pre><code>app.set('view engine', 'pug');<\/code><\/pre>\n<p><strong>3. Handlebars (hbs)<\/strong><\/p>\n<ul>\n<li>Uses {{ }} for placeholders.<\/li>\n<li>Great for cleaner, logic less templates.<\/li>\n<li>Example:<br \/>\n&lt;h1&gt;Hello {{name}}&lt;\/h1&gt;<\/li>\n<\/ul>\n<p><strong>Express setup:<\/strong><\/p>\n<pre><code>app.set('view engine', 'hbs');<\/code><\/pre>\n<p><strong>Example with Express<\/strong><\/p>\n<pre><code>const express = require('express');\r\n const app = express();\r\n \r\n app.set('view engine', 'ejs'); \/\/ using EJS\r\n \r\n app.get('\/', (req, res) =&gt; {\r\n   res.render('index', { name: 'Sahil' });\r\n });\r\n \r\n app.listen(3000, () =&gt; console.log('Server running on port 3000'));<\/code><\/pre>\n<p>index.ejs contains:<\/p>\n<pre><code>&lt;h1&gt;Welcome &lt;%= name %&gt;&lt;\/h1&gt;<\/code><\/pre>\n<p><strong>The browser will display:<\/strong><\/p>\n<p>Welcome Sahil<\/p>\n<p><strong>Summary<\/strong><\/p>\n<ul>\n<li>Template engines help create dynamic HTML pages.<\/li>\n<li>Popular ones in Express.js are EJS, Pug, and Handlebars.<\/li>\n<li>They allow you to mix HTML with variables and logic easily.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>What is a Template Engine?
