## 🚀 Server Management
|
||||||
|
|
||||||
CLI tested with:
|
### Starting the Server
|
||||||
- No arguments: `go run ./cmd/greet` → "Hello world!"
|
|
||||||
- With argument: `go run ./cmd/greet John` → "Hello John!"
|
```bash
|
||||||
|
# Navigate to project directory
|
||||||
|
cd /Users/gabrielradureau/Work/Vibe/DanceLessonsCoach
|
||||||
|
|
||||||
|
# Run server in background
|
||||||
|
go run cmd/server/main.go &
|
||||||
|
```
|
||||||
|
|
||||||
|
**Expected output:**
|
||||||
|
```
|
||||||
|
Server running on :8080
|
||||||
|
[INF] Starting HTTP server on :8080
|
||||||
|
[TRC] Registering greet routes
|
||||||
|
[TRC] Greet routes registered
|
||||||
|
```
|
||||||
|
|
||||||
|
**Features:**
|
||||||
|
- Context-aware server initialization
|
||||||
|
- Graceful shutdown handling
|
||||||
|
- Signal-based termination (SIGINT, SIGTERM)
|
||||||
|
- 30-second shutdown timeout
|
||||||
|
- Proper resource cleanup
|
||||||
|
|
||||||
|
### Checking Server Status
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check health endpoint
|
||||||
|
curl -s http://localhost:8080/api/health
|
||||||
|
```
|
||||||
|
|
||||||
|
**Expected response:** `{"status":"healthy"}`
|
||||||
|
|
||||||
|
### Stopping the Server
|
||||||
|
|
||||||
|
To stop the server gracefully:
|
||||||
|
```bash
|
||||||
|
# Send SIGTERM for graceful shutdown
|
||||||
|
pkill -TERM -f "go run"
|
||||||
|
|
||||||
|
# Or send SIGINT (Ctrl+C equivalent)
|
||||||
|
pkill -INT -f "go run"
|
||||||
|
```
|
||||||
|
|
||||||
|
**Graceful shutdown process:**
|
||||||
|
1. Server receives termination signal
|
||||||
|
2. Logs shutdown message
|
||||||
|
3. Stops accepting new connections
|
||||||
|
4. Waits up to 30 seconds for active requests to complete
|
||||||
|
5. Closes all connections cleanly
|
||||||
|
6. Exits with proper cleanup
|
||||||
|
|
||||||
|
For force stop (if graceful shutdown hangs):
|
||||||
|
```bash
|
||||||
|
pkill -f "go"
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verification:**
|
||||||
|
```bash
|
||||||
|
curl -s http://localhost:8080/api/health
|
||||||
|
# Should return connection refused
|
||||||
|
```
|
||||||
|
|
||||||
|

```
|
||||||
|
|
||||||
|
## 📝 Architecture Decisions
|
||||||
|
|
||||||
|
### Interface-Based Design
|
||||||
|
```go
|
||||||
|
type Greeter interface {
|
||||||
|
Greet(ctx context.Context, name string) string
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- Easy mocking for tests
|
||||||
|
- Dependency injection
|
||||||
|
- Multiple implementations
|
||||||
|
- Clear contracts
|
||||||
|
|
||||||
|
### Context-Aware Services
|
||||||
|
```go
|
||||||
|
func (s *Service) Greet(ctx context.Context, name string) string {
|
||||||
|
log.Trace().Ctx(ctx).Str("name", name).Msg("Greet function called")
|
||||||
|
// ...
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- Request tracing
|
||||||
|
- Cancellation support
|
||||||
|
- Deadline propagation
|
||||||
|
- Metadata passing
|
||||||
|
|
||||||
|
### Server Context Management
|
||||||
|
```go
|
||||||
|
// Root context with cancellation
|
||||||
|
ctx, cancel := context.WithCancel(context.Background())
|
||||||
|
defer cancel()
|
||||||
|
|
||||||
|
// Server context with graceful shutdown
|
||||||
|
serverCtx, serverStop := context.WithCancel(ctx)
|
||||||
|
|
||||||
|
// HTTP server with context-aware shutdown
|
||||||
|
srv := &http.Server{
|
||||||
|
Addr: ":8080",
|
||||||
|
Handler: server.Router(),
|
||||||
|
}
|
||||||
|
|
||||||
|
// Graceful shutdown with timeout
|
||||||
|
shutdownCtx, shutdownCancel := context.WithTimeout(
|
||||||
|
context.Background(),
|
||||||
|
30*time.Second
|
||||||
|
)
|
||||||
|
defer shutdownCancel()
|
||||||
|
|
||||||
|
if err := srv.Shutdown(shutdownCtx); err != nil {
|
||||||
|
log.Error().Err(err).Msg("Server shutdown failed")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- Graceful shutdown handling
|
||||||
|
- Signal-based termination (SIGINT, SIGTERM)
|
||||||
|
- 30-second timeout for active connections
|
||||||
|
- Proper resource cleanup
|
||||||
|
- Context propagation throughout server lifecycle
|
||||||
|
|
||||||
|
### Zerolog Logging
|
||||||
|
```go
|
||||||
|
zerolog.SetGlobalLevel(zerolog.TraceLevel)
|
||||||
|
log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- High performance
|
||||||
|
- Structured logging
|
||||||
|
- Trace level detail
|
||||||
|
- Color output
|
||||||
|
|
||||||
|
### Versioned API
|
||||||
|
```go
|
||||||
|
router.Route("/api/v1", func(r chi.Router) {
|
||||||
|
// v1 endpoints
|
||||||
|
})
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- Backward compatibility
|
||||||
|
- Clear versioning
|
||||||
|
- Easy migration
|
||||||
|
- Parallel versions
|
||||||
|
|
||||||
|
## 🔍 Troubleshooting
|
||||||
|
|
||||||
|
### Port Already in Use
|
||||||
|
```bash
|
||||||
|
# Find process using port 8080
|
||||||
|
lsof -i :8080
|
||||||
|
|
||||||
|
# Kill the process
|
||||||
|
kill -9 <PID>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Server Not Responding
|
||||||
|
```bash
|
||||||
|
# Check if running
|
||||||
|
curl -s http://localhost:8080/api/health
|
||||||
|
|
||||||
|
# Restart server
|
||||||
|
pkill -f "go"
|
||||||
|
go run cmd/server/main.go &
|
||||||
|
```
|
||||||
|
|
||||||
|
### Dependency Issues
|
||||||
|
```bash
|
||||||
|
# Clean and rebuild
|
||||||
|
go mod tidy
|
||||||
|
go build ./...
|
||||||
|
```
|
||||||
|
|
||||||
|
### Tests Failing
|
||||||
|
```bash
|
||||||
|
# Run with verbose output
|
||||||
|
go test -v ./...
|
||||||
|
|
||||||
|
# Check specific test
|
||||||
|
go test ./pkg/greet/ -run TestName
|
||||||
|
```
|
||||||
|
|
||||||
|
## 📚 Code Examples
|
||||||
|
|
||||||
|
### Adding New API Endpoint
|
||||||
|
```go
|
||||||
|
// 1. Add to interface
|
||||||
|
func (h *apiV1GreetHandler) RegisterRoutes(router chi.Router) {
|
||||||
|
router.Get("/", h.handleGreetQuery)
|
||||||
|
router.Get("/{name}", h.handleGreetPath)
|
||||||
|
router.Post("/custom", h.handleCustomGreet) // New endpoint
|
||||||
|
}
|
||||||
|
|
||||||
|
// 2. Implement handler
|
||||||
|
func (h *apiV1GreetHandler) handleCustomGreet(w http.ResponseWriter, r *http.Request) {
|
||||||
|
// Parse request
|
||||||
|
// Call service
|
||||||
|
// Return JSON response
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Adding Logging
|
||||||
|
```go
|
||||||
|
// Trace level logging
|
||||||
|
log.Trace().Ctx(ctx).Str("key", "value").Msg("message")
|
||||||
|
|
||||||
|
// Info level
|
||||||
|
log.Info().Msg("Important event")
|
||||||
|
|
||||||
|
// Error level
|
||||||
|
log.Error().Err(err).Msg("Error occurred")
|
||||||
|
```
|
||||||
|
|
||||||
|
### Using Context
|
||||||
|
```go
|
||||||
|
// Pass context through calls
|
||||||
|
func handler(w http.ResponseWriter, r *http.Request) {
|
||||||
|
result := service.Greet(r.Context(), "John")
|
||||||
|
// ...
|
||||||
|
}
|
||||||
|
|
||||||
|
// Create context with values
|
||||||
|
ctx := context.WithValue(r.Context(), "key", "value")
|
||||||
|
|
||||||
|
// Create context with timeout
|
||||||
|
ctx, cancel := context.WithTimeout(r.Context(), 5*time.Second)
|
||||||
|
defer cancel()
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🎓 Best Practices
|
||||||
|
|
||||||
|
### Code Organization
|
||||||
|
- Keep handlers thin, move logic to services
|
||||||
|
- Use interfaces for dependencies
|
||||||
|
- Separate route registration from handlers
|
||||||
|
- Group related functionality
|
||||||
|
|
||||||
|
### Error Handling
|
||||||
|
- Return proper HTTP status codes
|
||||||
|
- Log errors with context
|
||||||
|
- Don't expose internal errors to clients
|
||||||
|
- Use structured error responses
|
||||||
|
|
||||||
|
### Performance
|
||||||
|
- Use Zerolog's Trace level sparingly in production
|
||||||
|
- Avoid allocations in hot paths
|
||||||
|
- Use context timeouts for external calls
|
||||||
|
- Batch database operations
|
||||||
|
|
||||||
|
### Testing
|
||||||
|
- Test interfaces, not implementations
|
||||||
|
- Use table-driven tests
|
||||||
|
- Test error cases
|
||||||
|
- Mock dependencies
|
||||||
|
|
||||||
|
