# HTTP Server Setup and Dependency Injection
## Overview
The Tender Management API server has been successfully initialized with proper dependency injection following Clean Architecture principles. The server uses Echo v4 as the HTTP framework and implements a complete dependency injection chain.
## Architecture
### Dependency Injection Chain
```
MongoDB Connection Manager
Repositories
Services
Handlers
HTTP Server (Echo)
```
### Components
1. **MongoDB Connection Manager** (`pkg/mongo/connection.go`)
- Manages database connections and pooling
- Provides connection to repositories
2. **Repositories** (`internal/customer/repository.go`)
- Data access layer
- Implements repository pattern
- Handles database operations
3. **Services** (`internal/customer/service.go`)
- Business logic layer
- Implements use cases
- Depends on repositories
4. **Handlers** (`internal/customer/handler.go`)
- HTTP request/response handling
- Input validation
- Depends on services
5. **HTTP Server** (`cmd/web/main.go`)
- Echo v4 server with middleware
- Route registration
- Server lifecycle management
## Server Features
### Middleware Stack
1. **Recover** - Panic recovery
2. **RequestID** - Unique request identification
3. **Logger** - Request logging
4. **CORS** - Cross-origin resource sharing
5. **Custom Logging** - Structured request logging
### Endpoints
#### Health Check
- `GET /health` - Server health status
#### Customer Endpoints
- `POST /api/customers/login` - Customer login
- `POST /api/customers/refresh-token` - Token refresh
- `GET /api/customers/profile` - Get profile (protected)
- `PUT /api/customers/profile` - Update profile (protected)
- `PUT /api/customers/change-password` - Change password (protected)
- `POST /api/customers/device-token` - Add device token (protected)
- `DELETE /api/customers/device-token` - Remove device token (protected)
- `POST /api/customers/logout` - Logout (protected)
#### Admin Endpoints
- `POST /api/admin/customers/register` - Register customer (admin)
- `GET /api/admin/customers` - List customers (admin)
- `GET /api/admin/customers/:id` - Get customer by ID (admin)
- `PUT /api/admin/customers/:id/status` - Update customer status (admin)
- `GET /api/admin/customers/device-tokens` - Get all device tokens (admin)
## Configuration
### Server Configuration (`config.yaml`)
```yaml
server:
host: "0.0.0.0"
port: 8081
timeout: 30s
read_timeout: 10s
write_timeout: 10s
```
### Database Configuration
```yaml
database:
mongodb:
uri: "mongodb://localhost:27017"
name: "tender_management"
timeout: 10s
max_pool_size: 100
```
## Running the Server
### Prerequisites
1. **MongoDB** - Must be running locally or accessible
2. **Go 1.23+** - Required for compilation
3. **Configuration** - `config.yaml` must be present
### Build and Run
```bash
# Build the server
go build -o bin/web ./cmd/web
# Run the server
./bin/web
```
### Development
```bash
# Run with hot reload (if using air)
air
# Or run directly
go run ./cmd/web
```
## Testing
### Health Check
```bash
curl http://localhost:8081/health
```
Expected response:
```json
{
"status": "healthy",
"time": 1703123456,
"version": "1.0.0"
}
```
### Customer Registration
```bash
curl -X POST http://localhost:8081/api/admin/customers/register \
-H "Content-Type: application/json" \
-d '{
"full_name": "John Doe",
"username": "johndoe",
"email": "john@example.com",
"mobile": "+1234567890",
"password": "securepassword123",
"national_id": "123456789",
"gender": "male"
}'
```
## Logging
The server implements structured logging with the following features:
- **Request Logging** - All HTTP requests are logged with timing
- **Error Logging** - Errors are logged with context
- **Structured Fields** - Logs include relevant metadata
- **File Rotation** - Logs are rotated based on size and age
### Log Configuration
```yaml
logging:
level: "info"
format: "json"
output: "file"
file:
path: "./logs/app.log"
max_size: 100
max_backups: 5
max_age: 30
compress: true
```
## Security Features
### CORS Configuration
```go
middleware.CORSWithConfig(middleware.CORSConfig{
AllowOrigins: []string{"*"}, // Configure for production
AllowMethods: []string{http.MethodGet, http.MethodPost, http.MethodPut, http.MethodDelete, http.MethodOptions},
AllowHeaders: []string{echo.HeaderOrigin, echo.HeaderContentType, echo.HeaderAccept, echo.HeaderAuthorization},
})
```
### Authentication (TODO)
- JWT token validation
- Role-based access control
- Token refresh mechanism
## Error Handling
### HTTP Status Codes
- `200` - Success
- `201` - Created
- `400` - Bad Request
- `401` - Unauthorized
- `404` - Not Found
- `409` - Conflict
- `422` - Validation Error
- `500` - Internal Server Error
### Response Format
```json
{
"success": true,
"message": "Operation successful",
"data": {},
"meta": {}
}
```
## Monitoring
### Health Check
The `/health` endpoint provides basic server status:
- Server status
- Current timestamp
- Version information
### Request Metrics
Each request is logged with:
- HTTP method
- Request path
- Response status
- Processing duration
- User agent
- Remote IP
## Future Enhancements
1. **Authentication Middleware** - Implement JWT validation
2. **Rate Limiting** - Add request rate limiting
3. **Metrics** - Add Prometheus metrics
4. **Tracing** - Add distributed tracing
5. **API Documentation** - Add Swagger/OpenAPI docs
6. **Testing** - Add comprehensive test suite
## Troubleshooting
### Common Issues
1. **MongoDB Connection Failed**
- Ensure MongoDB is running
- Check connection URI in config
- Verify network connectivity
2. **Port Already in Use**
- Change port in config.yaml
- Kill existing process using the port
3. **Permission Denied**
- Ensure write permissions for log directory
- Check file permissions
### Debug Mode
To enable debug logging, change the log level in config.yaml:
```yaml
logging:
level: "debug"
```

- `GET /api/admin/customers/{id}` - Get customer by ID
- `PUT /api/admin/customers/{id}/status` - Update customer status
## 🛠️ Development
### Adding New Endpoints
1. **Add Swagger Annotations** to your handler functions:
```go
// @Summary Endpoint summary
// @Description Detailed description
// @Tags tag-name
// @Accept json
// @Produce json
// @Security BearerAuth
// @Param param-name param-type param-required "param description"
// @Success 200 {object} response.APIResponse{data=YourResponseType} "Success description"
// @Failure 400 {object} response.APIResponse "Error description"
// @Router /api/endpoint [method]
func (h *Handler) YourHandler(c echo.Context) error {
// Your handler implementation
}
```
2. **Regenerate Documentation**:
```bash
make docs
```
### Swagger Annotation Examples
#### Basic GET Endpoint
```go
// @Summary Get resource
// @Description Get a resource by ID
// @Tags resources
// @Accept json
// @Produce json
// @Param id path string true "Resource ID"
// @Success 200 {object} response.APIResponse{data=ResourceResponse}
// @Failure 404 {object} response.APIResponse
// @Router /api/resources/{id} [get]
```
#### POST with Request Body
```go
// @Summary Create resource
// @Description Create a new resource
// @Tags resources
// @Accept json
// @Produce json
// @Param resource body CreateResourceForm true "Resource data"
// @Success 201 {object} response.APIResponse{data=ResourceResponse}
// @Failure 400 {object} response.APIResponse
// @Router /api/resources [post]
```
#### Protected Endpoint
```go
// @Summary Protected endpoint
// @Description This endpoint requires authentication
// @Tags resources
// @Accept json
// @Produce json
// @Security BearerAuth
// @Success 200 {object} response.APIResponse
// @Failure 401 {object} response.APIResponse
// @Router /api/protected [get]
```
## 📁 File Structure
```

internal/customer/
├── handler.go # HTTP handlers with Swagger annotations
├── form.go # Request/response forms
└── ...
pkg/response/
└── response.go # Standard API response types
```
## 🔧 Configuration
### Swagger Configuration
The main Swagger configuration is in `cmd/web/docs.go`:
```go
// @title Tender Management API
// @version 1.0.0
// @description This is the API documentation for the Tender Management System.
// @host localhost:8081
// @BasePath /api/v1
// @securityDefinitions.apikey BearerAuth
// @in header
// @name Authorization
```
### Server Configuration
The Swagger endpoint is registered in `cmd/web/bootstrap.go`:
```go
// Add Swagger documentation endpoint
e.GET("/swagger/*", echoSwagger.WrapHandler)
```
## 🧪 Testing
### Using the Test Script
```bash
# Run the test script
./test_swagger.sh
```
This script will:
1. Build the application
2. Start the server
3. Display all available endpoints
4. Provide access URLs
### Manual Testing
1. **Start the server**:
```bash
make run-docs
```
2. **Access Swagger UI**:
- Open http://localhost:8081/swagger/index.html
- Explore and test endpoints interactively
3. **Test Health Check**:
```bash
curl http://localhost:8081/health
```
## 📝 Response Types
### Standard Response Structure
All API responses follow this structure:
```json
{
"success": true,
"message": "Operation successful",
"data": {
// Response data
},
"meta": {
// Pagination metadata (if applicable)
},
"error": {
// Error details (if applicable)
}
}
```
### Error Response
```json
{
"success": false,
"message": "Error message",
"error": {
"code": "ERROR_CODE",
"message": "Detailed error message",
"details": "Additional details"
}
}
```
## 🔐 Authentication
### Bearer Token Authentication
Most endpoints require Bearer token authentication:
1. **Login** to get access token:
```bash
curl -X POST http://localhost:8081/api/customers/login \
-H "Content-Type: application/json" \
-d '{"email": "user@example.com", "password": "password"}'
```
2. **Use the token** in subsequent requests:
```bash
curl -X GET http://localhost:8081/api/customers/profile \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
```
## 🚨 Troubleshooting
### Common Issues
1. **Documentation not updating**:
```bash
make clean
make docs
make build
```
2. **Swagger annotations not recognized**:
- Ensure annotations are directly above the function
- Check for syntax errors in annotations
- Verify import paths are correct
3. **Server won't start**:
- Check if port 8081 is available
- Verify MongoDB connection
- Check configuration files
### Debug Commands
```bash
# Check if swag is installed
swag --version
# Generate docs with verbose output
swag init -g cmd/web/main.go -o cmd/web/docs --parseDependency
# Check generated files
ls -la cmd/web/docs/
```
