Lecture 289:- Install EJS and Setup View Engine

To install EJS and set up the view engine in an Express application, you need to follow these steps:

1. Open your project in the terminal and run the following command to install EJS:

Copy code

npm install ejs

1. In your app.js file, add the following code to set EJS as the view engine:

javascriptCopy code

const express = require('express'); const app = express(); // Set EJS as the view engine app.set('view engine', 'ejs');

1. Create an views directory in the root of your project.
2. Create an index.ejs file in the views directory. This will be the default view for your application.
3. In the index.js controller, update the response to use the render method and specify the name of the view to render.

javascriptCopy code

const express = require('express'); const router = express.Router(); router.get('/', (req, res) => {  res.render('index'); }); module.exports = router;

1. Run your application and test that EJS is rendering the index.ejs file correctly.

Note that you can also set the directory where your views are located with the following code:

javascriptCopy code

app.set('views', './views');

This specifies that the views are located in the views directory, which is in the root of the project.
