⚙️ Taskemer Server

The robust, scalable backend foundation for the Taskemer productivity ecosystem.

Taskemer Server is a secure RESTful API built with Java and Spring Boot. It acts as the central hub for the Taskemer Android application, handling user authentication, data persistence, and complex task lifecycles.

The codebase is engineered with maintainability in mind, strictly adhering to a 3-Layer Architecture (Controller, Service, Repository) to ensure clean separation of concerns.

✨ Key Features

• Secure Authentication: Stateless session management using Spring Security and JWT (JSON Web Tokens).
• Complex Task Lifecycles: Comprehensive endpoints for creating, updating, and managing projects and tasks.
• Flexible Attachments: Supports hybrid attachment handling, allowing users to attach either physical files or external URLs to their tasks.
• Relational Data Mapping: Efficient database interactions and relationship mapping using Spring Data JPA and MySQL.
• Clean Architecture: Strict adherence to Controller-Service-Repository layers with dedicated DTOs (Data Transfer Objects) to protect database entities from external exposure.

🛠 Tech Stack

• Language: Java 26+
• Framework: Spring Boot 4.0
• Database: MySQL
• ORM: Spring Data JPA / Hibernate
• Security: Spring Security & JWT
• Build Tool: Maven
• API Architecture: REST

🏗 Architecture Overview

The application follows a strict 3-Layer Architecture:

1. Controller Layer (API): Intercepts HTTP requests, validates incoming payloads, and returns formatted HTTP responses and DTOs.
2. Service Layer (Business Logic): Contains the core business rules. It processes data, applies authorization rules, and acts as the bridge between the controllers and the database.
3. Repository Layer (Data Access): Interfaces directly with the MySQL database using Spring Data JPA, executing queries and returning Entities.
