- **JWT Authentication** - Secure user authentication
- **Role-based Authorization** - Admin, Instructor, Student roles
- **Multi-language Support** - Thai and English
- **File Upload** - Video and attachment support with MinIO/S3
- **Rate Limiting** - API protection
- **Comprehensive Error Handling** - Structured error responses
## 📋 Prerequisites
- Node.js >= 18
- Docker & Docker Compose

- MinIO (via Docker)
## 🛠️ Setup
### 1. Install Dependencies
```bash
npm install
```
### 2. Environment Configuration
```bash
cp .env.example .env
# Edit .env with your configuration
```
### 3. Start Docker Services
```bash

## 📝 Development Workflow
1. Create a new controller in `src/controllers/`
2. Add TSOA decorators (`@Route`, `@Get`, `@Post`, etc.)
3. Run `npm run tsoa:gen` to generate routes
4. Implement business logic in `src/services/`
5. Test your endpoints
## 🧪 Testing
```bash
npm test # Run all tests
npm run test:watch # Run tests in watch mode
npm run test:coverage # Generate coverage report
```
## 🚀 Deployment
See [Deployment Workflow](./.agent/workflows/deployment.md) for production deployment instructions.
