Online Learning System 3AKO

Project Description

Course

Advanced Computer Lab (CSEN 704/ DMET 706), Winter 2022

Theme

The theme of the project, is to create an Online Learning System. An Online Learning System is a web application through which trainees can enroll in online courses and Instructors can add courses to the system for trainees which they get paid for. Such websites include coursera.com and udemy.com

Overview

This project followed the Agile Methodology; meaning it was splited into Sprints, with each Sprint lasting a set amount of time and a fully functioning version of the project with the specified System Requirements should be submitted and evaluated.

Objectives

Learn how to properly use the Agile Methodology to plan out a project and develop the software.
Learn the process of following a given set of System Requirements to develop a software.
Learn to research and master the use of the MERN Stack.
Learn how to work together as a team on GitHub.

Tools and Frameworks

What is the MERN Stack?

MERN stands for MongoDB, Express, React, Node, after the four key technologies that make up the stack.

MongoDB - document database
Express(.js) - Node.js web framework
React(.js) - a client-side JavaScript framework
Node(.js) - the premier JavaScript web server

Express and Node make up the middle (application) tier. Express.js is a server-side web framework, and Node.js the popular and powerful JavaScript server platform. Regardless of which variant you choose, ME(RVA)N is the ideal approach to working with JavaScript and JSON, all the way through.

How does the MERN stack work?

The MERN architecture allows you to easily construct a 3-tier architecture (frontend, backend, database) entirely using JavaScript and JSON.

- React.js Front End

The top tier of the MERN stack is React.js, the declarative JavaScript framework for creating dynamic client-side applications in HTML. React lets you build up complex interfaces through simple Components, connect them to data on your backend server, and render them as HTML.

React’s strong suit is handling stateful, data-driven interfaces with minimal code and minimal pain, and it has all the bells and whistles you’d expect from a modern web framework: great support for forms, error handling, events, lists, and more.

- Express.js and Node.js Server Tier

The next level down is the Express.js server-side framework, running inside a Node.js server. Express.js bills itself as a “fast, unopinionated, minimalist web framework for Node.js,” and that is indeed exactly what it is. Express.js has powerful models for URL routing (matching an incoming URL with a server function), and handling HTTP requests and responses.

By making XML HTTP Requests (XHRs) or GETs or POSTs from your React.js front-end, you can connect to Express.js functions that power your application. Those functions in turn use MongoDB’s Node.js drivers, either via callbacks for using Promises, to access and update data in your MongoDB database.

- MongoDB Database Tier

If your application stores any data (user profiles, content, comments, uploads, events, etc.), then you’re going to want a database that’s just as easy to work with as React, Express, and Node.

That’s where MongoDB comes in: JSON documents created in your React.js front end can be sent to the Express.js server, where they can be processed and (assuming they’re valid) stored directly in MongoDB for later retrieval. Again, if you’re building in the cloud, you’ll want to look at Atlas. If you’re looking to set up your own MERN stack, read on!

Installation

To get started, you will need to do the following:

Install Node

To install Node, go to https://nodejs.org/en/ and download either the LTS version or the current version.

Have or Install a Code Editor

You can use any code editor of your choice for this tutorial. However, for the sake of demonstration, we will be using VS Code editor with the plugin prettier and vscode icons.

Install dependencies

Run script npm i in the frontend and backend directories using the terminal

Testing

API testing was done using Postman, a request was sent with a given body and a specific response was expected. various test cases were used in the process of testing these APIs, cases where the body is valid, not valid, with user authentication, or without user authentication. In this section, different outcomes of API responses will be shown.
