EXPRESS APP REGISTER HANDLEBARS VIEW ENGINE

To register the Handlebars view engine in an Express app, you need to follow these steps:

  1. Install the necessary dependencies:

  2. Use the package manager npm (Node Package Manager) to install the required packages. Run the following command in your terminal: npm install express express-handlebars

  3. Import the necessary modules:

  4. In your JavaScript file (e.g., app.js), import the required modules using the require function. Add the following lines of code at the beginning of your file: javascript const express = require('express'); const exphbs = require('express-handlebars');

  5. Create an Express application:

  6. Create an instance of the Express application using the express() function. This will initialize your Express app. Add the following line of code after the module imports: javascript const app = express();

  7. Configure the Handlebars view engine:

  8. Set the Handlebars view engine as the default view engine for your Express app. Add the following lines of code after creating the Express app instance: javascript app.engine('handlebars', exphbs()); app.set('view engine', 'handlebars');

  9. Define routes and render views:

  10. Set up your routes and render views using the Handlebars templates. Here's an example of a route that renders a Handlebars view: javascript app.get('/', (req, res) => { res.render('home', { title: 'Express App' }); });

  11. Start the server:

  12. Finally, start the Express server to listen for incoming requests. Add the following line of code at the end of your file: javascript const port = 3000; // Or any other port number you prefer app.listen(port, () => { console.log(`Server started on port ${port}`); });

By following these steps, you will be able to register the Handlebars view engine in your Express app and render dynamic views using Handlebars templates. Feel free to modify the code according to your specific requirements.
