In this course, you’ll learn how to build a full-stack application using the MEAN stack. You’ll begin with the frontend by learning how to create and set up an Angular application from scratch. Furthermore, you’ll learn to implement routing, router guards, token-based authentication, authorization, error handling, and dependency Injection in an Angular application.

Next, the focus shifts to the backend. You’ll learn by using Node.js, Express, and MongoDB to create REST APIs. Additionally, you’ll learn to create middleware for handling errors, token verification, setting up models and schemas, creating a database using MongoDB, as well as the concept of separation of concern.

By the end of this course, you will have an understanding of how to connect both the backend and the frontend together to create a full-stack application, as well as how to deploy a fully functional application.

Building a Full-stack Application Using the MEAN Stack

# Challenge description
In this challenge, we’ll use the `HTTP` module in Node.js to create a server. We’ll use the `createServer()` method, which helps us execute the request. The exercise will be implemented by taking the following steps:

* Step 1: Import the `HTTP` module.
* Step 2: Create a variable that holds the server’s functionality using the `http.createServer()` method.
* Step 3: Inside the `createServer()` method, we use the `res.writeHead()` method to set the content type as `text/html`, while we use the `res.end()` method to write HTML using template literal. We’ll create an `h2` tag that includes the text “Welcome to the MEAN stack course on Educative.”
 
* Step 4: Finally, we’ll chain our function to the `listen()` method to work on port `5000`. We can then start the server with the command below:

```
node server.js
```

The expected output should look like the image we have below:
