Software Engineering Project (2025S) – 4-Layer Web Application

Overview

This project was developed as part of the "Software Engineering Project" lecture. It demonstrates the implementation of a four-layer web application architecture using Java, Spring Boot, Angular, TypeScript, and SQL.
This submission represents the individual phase of the course; the group project will follow as a separate stage.

Architecture

The application is structured into four layers:

• Frontend: Built with Angular and TypeScript, providing an interactive user interface.
• REST Layer: Defines and exposes RESTful APIs for communication between frontend and backend.
• Service Layer: Implements business logic using Java and Spring Boot.
• Persistence Layer: Manages data storage with SQL.

Getting Started

Prerequisites

• Java: OpenJDK 21
• Node.js: Version 22.14.0
• npm: Version 10.9.2
• Git: Version 2.x
• Maven: Version 3.x

Backend

Run the Spring Boot application:

cd backend
mvn clean install
mvn spring-boot:run

The backend should now be running on http://localhost:8080.

Frontend

Open a new terminal and run:

cd frontend
npm install
npm run start

The frontend should now be available at http://localhost:4200.
