The MEAN stack is a JavaScript-based framework for developing scalable web applications. The term MEAN is an acronym for MongoDB, Express, Angular, and Node — the four key technologies that make up the layers of the technology stack.

MongoDB: A NoSQL, object-oriented database designed for use with cloud applications

Express(.js): A web application framework for Node(.js) that supports interactions between the front end (e.g., the client side) and the database

Angular(.js): Often referred to as the “front end"; a client-side JavaScript framework used to create dynamic web applications to work with interactive user interfaces.

Node(.js): The premier JavaScript web server used to build scalable network applications.

Deploying a Web Book Register Application on an Ubuntu AWS EC2 instance using the MEAN stack (MongoDB, Express, Angular, Node.js) involves several steps. Here’s a step-by-step guide:

Step 1: Provision an AWS Instance
Launch an EC2 Instance:

• Use the AWS Console to launch an Ubuntu Server (e.g., 22.04 LTS).

• Choose an instance type (e.g., t2.micro for free tier).

• Configure security groups to allow:

SSH (port 22) for server access.
HTTP (port 80) and HTTPS (port 443) for web traffic.

• Connect to the Instance:

Step 2: Install Node.js
Node.js is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.

• Update System Packages:

• Add certificates:

• Install Node.js:

Step 3: Install MongoDB
Follow these steps to install MongoDB Community Edition using the apt package manager.

• Install gnupg and curl if they are not already available:

• Create the List File Create the list file for Ubuntu 24.04 (Noble):

• Reload the Package Database Issue the following command to reload the local package database:

• Install MongoDB Community Server You can install either the latest stable version of MongoDB or a specific version of MongoDB.

• Init System

To run and manage your mongod process, you will be using your operating system's built-in init system.
If you are unsure which init system your platform uses, run the following command:

• Start and verify MongoDB. You can start the mongod process and Verify that MongoDB has started successfully by issuing the following commands:

• Install npm (Node Package Manager):

Note: I faced issues with installing the npm, so I used aptitude to Resolve Dependencies. If you face issues, you can try using aptitude (an alternative package manager) to handle the dependency resolution:
aptitude:

• Install aptitude:

Then, try installing npm using:

• Install the body-parser package:

• Create a folder for the project:

• Initialize the npm project:

• Create a file named server.js and add the following code:

Step 4: Install Express and Set Up Routes

• Install Express and Mongoose:

• Create a folder named apps:

• Create a file named routes.js and add the following code:

• Create a folder named models:

• Create a file named book.js and add the following code:

Step 5: Access the Routes with AngularJS

• Change the directory back to Books:

• Create a folder named public

• Create a file named script.js and add the following code:

• In the public folder, create a file named index.html and add the following code:

Step 6: Run the App

• Go back to the project root directory and run the following command:

• Opening TCP port 3300 on AWS Web Console for your EC2 Instance to access it from the Internet.

• Accessing the Book Register Application by opening a browser and going to http://:3300

• Testing the Book Management Application:
