Templating Engines and Views in Express.js – Dynamic Web Pages
1. Integrating Templating Engines:
- Popular choices include EJS, Pug (formerly Jade), and Handlebars.
- Install the chosen templating engine using npm:
npm install ejs(for example).
// Example: Integrating EJS Templating Engine
app.set('view engine', 'ejs');
2. Creating Dynamic Views in Express.js:
- Render dynamic content using variables in templates.
- Pass data from the server to views using the
res.render()method.
// Example: Rendering Dynamic Content with EJS
app.get('/dynamic', (req, res) => {
const data = { message: 'Hello, Dynamic World!' };
res.render('dynamicPage', data);
});
3. Layouts and Partials for Reusability:
- Use layouts for consistent page structure.
- Partials allow code reusability for common elements.
<!-- Example: Using EJS Layouts and Partials -->
<!-- views/layout.ejs -->
<html>
<head><title>Express.js Layout</title></head>
<body>
<%- body %>
<% include('footer'); %>
</body>
</html>
<!-- views/footer.ejs -->
<footer>© 2024 Your Website</footer>
