Task Management System

A comprehensive full-stack task management application with multiple frontend interfaces and a backend API. This system provides task creation, assignment, tracking, and management capabilities with user authentication and role-based access control.

🏗️ System Architecture

The project consists of four main components:

• Backend API (be/) - FastAPI-based REST API with MySQL database
• React Frontend (task-manager-app/) - Modern web application for end users
• PHP Admin Panel (fe-admin-panel/) - Administrative interface for system management
• Database - MySQL database for data persistence

🚀 Quick Start with Docker

The easiest way to run the entire system is using Docker Compose:

# Clone the repository
git clone <repository-url>
cd task-management

# Start all services
docker-compose up -d

# Access the applications:
# - React App: http://localhost:3000
# - PHP Admin Panel: http://localhost/index.php
# - API Documentation: http://localhost:8000/docs
# - Database: localhost:3306

📋 Prerequisites

For Docker Deployment

• Docker and Docker Compose

For Local Development

• Python 3.11+ (Backend)
• Node.js 18+ (React Frontend)
• PHP 8.0+ with Apache (Admin Panel)
• MySQL 8.0+ (Database)
• XAMPP
• Composer (PHP dependencies)

All services are connected via a custom bridge network for internal communication.

🔧 Development Workflow

Adding New Features

1. Backend: Add models, services, and API endpoints in be/
2. Frontend: Create components and hooks in task-manager-app/
3. Admin Panel: Add administrative features in fe-admin-panel/
4. Testing: Write tests for backend functionality
5. Documentation: Update relevant README files

Code Style

• Python: Follow PEP 8 guidelines
• TypeScript: Use ESLint configuration
• PHP: Follow PSR-12 standards
