Build Binaries - -The project uses a build script to compile binaries into the `bin/` directory: - -```bash -# Build both server and greet binaries -./scripts/build.sh - -# This creates: -# - ./bin/server - The web server binary -# - ./bin/greet - The CLI greeting tool -``` - -**Binary Usage:** -```bash -# Run the server -./bin/server - -# Use the greet CLI -./bin/greet # Output: Hello world! -./bin/greet John # Output: Hello John! -``` - -**The `bin/` directory is gitignored** to prevent binary files from being committed to the repository. - -### 6.

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 - -## 📈 Future Enhancements - -### Potential Features -- [ ] Database integration -- [ ] Authentication/Authorization -- [ ] Rate limiting -- [ ] Metrics and monitoring -- [ ] Docker containerization -- ✅ CI/CD pipeline ([ADR-0016](adr/0016-ci-cd-pipeline-design.md), [ADR-0017](adr/0017-trunk-based-development-workflow.md)) -- [ ] Configuration hot reload -- [ ] Circuit breakers -
