# Development History
|
|
|
|
This document records the historical development phases of `dance-lessons-coach`. Extracted from the original `AGENTS.md` (Tâche 6 restructure) for lazy-loading compatibility with Mistral Vibe (128k context).
|
|
|
|
All phases below are **completed** ✅. They are kept here for traceability and onboarding context — refer to ADRs (`adr/`) for the technical decisions behind each phase.
|
|
|
|
## Phase 1: Foundation
|
|
|
|
- Go 1.26.1 environment setup
|
|
- Project structure with `cmd/` and `pkg/` directories
|
|
- Core Greet service implementation
|
|
- CLI interface
|
|
- Unit tests
|
|
|
|
## Phase 2: Web API
|
|
|
|
- Chi router integration
|
|
- Versioned API endpoints (`/api/v1`)
|
|
- Health endpoint (`/api/health`)
|
|
- JSON responses with proper headers
|
|
|
|
## Phase 3: Logging & Architecture
|
|
|
|
- Zerolog integration with Trace level
|
|
- Context-aware logging
|
|
- Interface-based design patterns
|
|
- Dependency injection
|
|
|
|
## Phase 4: Documentation & Testing
|
|
|
|
- Comprehensive `AGENTS.md`
|
|
- `README.md` with usage instructions
|
|
- Server management guide
|
|
- API endpoint documentation
|
|
|
|
## Phase 5: Configuration Management
|
|
|
|
- Viper integration for configuration
|
|
- Environment variable support with `DLC_` prefix
|
|
- Customizable server host/port
|
|
- Configurable shutdown timeout
|
|
- Configuration validation and logging
|
|
- Example configuration file
|
|
|
|
## Phase 6: Graceful Shutdown
|
|
|
|
- Context-aware server initialization
|
|
- Signal-based termination (`SIGINT`, `SIGTERM`)
|
|
- Configurable shutdown timeout
|
|
- Readiness endpoint for Kubernetes/service mesh integration
|
|
- Proper resource cleanup during shutdown
|
|
- Health endpoint remains healthy during graceful shutdown
|
|
|
|
## Phase 7: OpenTelemetry Integration
|
|
|
|
- OpenTelemetry Go libraries integration
|
|
- Jaeger compatibility for distributed tracing
|
|
- Middleware-only approach using `otelhttp.NewHandler`
|
|
- Configurable sampling strategies
|
|
- Graceful shutdown of tracer provider
|
|
- OTLP exporter with gRPC support
|
|
|
|
## Phase 8: Build System & Documentation
|
|
|
|
- Build script for binary compilation
|
|
- Binary output to `bin/` directory
|
|
- Comprehensive commit conventions with gitmoji reference
|
|
- Updated documentation with Jaeger integration guide
|
|
- Cleaned up configuration files
|
|
- Enhanced logging configuration with file output support
|
|
|
|
## Phase 9: Final Refinements
|
|
|
|
- Removed unnecessary `time.Sleep` for log flushing
|
|
- Changed server operational logs from Info to Trace level
|
|
- Moved all logging setup logic to config package
|
|
- Simplified server entrypoint to 27 lines
|
|
- Verified all functionality with comprehensive testing
|
|
- Updated documentation to reflect final architecture
|
|
|
|
## Beyond Phase 9
|
|
|
|
Subsequent work (CI/CD, BDD scenarios, ADR audit, JWT, config hot-reloading) is tracked in the [Changelog](../CHANGELOG.md) and the corresponding [ADRs](../adr/).
