🎉 Event Platform – Backend API

This is the backend for a collaborative event management platform built using Node.js, Express.js, and MongoDB, following a monolith architecture. It enables users to create, manage, and set number of participate in events updates.

✨ Features

• 📅 Event management: Create, update, delete, and view events
• 🔗 RESTful APIs for events, users and Auth
• 🐳 Docker support for development and production
• 📚 OpenAPI documentation with Swagger
• 🏗️ Monolith architecture for scalability
• 🛡️ TypeScript for type safety
• ✅ Data validation with Joi

---

🚀 Quick Start

🔧 Requirements

• Node.js v18+
• pnpm (package manager)
• Docker & Docker Compose (optional, but recommended)

📥 Installation

Option 1: Local Development (without Docker)

# Clone the repository
git clone https://github.com/your-org/event-platform.git
cd event-platform

# Install dependencies
pnpm install

# Copy environment file
cp .env.example .env


# Edit `.env` and configure your MongoDB URI
# Example: MONGODB_URI=mongodb://localhost:27017/event-platform

# Start the development server
pnpm run dev

Server will run by default on: http://localhost:3001

Option 2: Docker Development

Make sure Docker and Docker Compose are installed.

Development Environment

make dev         # Start development environment
make dev-build   # Build and start development
make dev-down    # Stop development environment

Production Environment

make prod        # Start production environment
make prod-build  # Build and start production
make prod-down   # Stop production environment

Useful Docker Commands

make logs        # View container logs
make restart     # Restart containers
make clean       # Remove volumes and prune
make clean-dev   # Clean development environment

📑 API Documentation

📖 The API documentation is auto-generated using Swagger (OpenAPI).

• URL: http://localhost:3001/api-docs
• Format: YAML files stored in src/docs/
• Tags: User, Auth, Event

API Endpoints Overview

• Auth: /api/ - Authentication and authorization
• Users: /api/users - User management
• Events: /api/events - Event operations

---

🧪 Example Data

👤 Example User

{
  "email": "[email protected]",
  "password": "123456Aa"
}

📆 Example Event

{
  "title": "Team Hackathon",
  "date": "2025-08-15",
  "location": "Berlin",
  "nbParticipants": 50
}

📘 API Endpoints Overview

Method	Endpoint	Description	Protected
POST	/api/register	Register a new user	❌
POST	/api/login	User login (JWT issued)	❌
GET	/api/events	List all events	✅
POST	/api/events	Create a new event	✅
