certainly! ejs (embedded javascript) is a templating engine that lets you generate html markup with plain javascript. it integrates seamlessly with express, a popular web framework for node.js. below is a step-by-step tutorial on how to use ejs with express.

prerequisites
node.js installed on your machine.
basic knowledge of javascript and node.js.

step 1: set up your project

1. **create a new directory for your project**:


2. **initialize a new node.js project**:


3. **install express and ejs**:


step 2: create your express application

1. **create an `index.js` file**:


2. **set up the basic express server in `index.js`**:


step 3: create the views directory and ejs file

1. **create a `views` directory**:


2. **create an `index.ejs` file inside the `views` directory**:


3. **add html and ejs code to `index.ejs`**:


step 4: run your server

1. **start the server**:


2. *open your browser and go to* `http://localhost:3000`. you should see your ejs-rendered page.

step 5: passing data to ejs

you can pass dynamic data to your ejs templates. let’s create an example where we pass an array of items to be displayed.

1. **update `index.js` to include an array of items**:


2. **create a new ejs file for the items**:


3. **add the following code to `items.ejs`**:


4. *access the items page by navigating to* `http://localhost:3000/items`.

conclusion

you now have a basic express application that uses ejs for templating. you learned how to set up an express server, create views with ejs, and pass data from the server to the views.

additional features

**partial views**: you can create reusable components (partials) by creating a `_header.ejs` and `_footer.ejs` and including them in other templates.
**layout**: use `ejs-locals` or similar middleware to implement layouts.
**static files**: serve css, javascript, and images with `express.static`.
