# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Commands
### Testing
- Run all tests: `go test ./...`
- Run tests with verbose output: `go test -v ./...`
- Run tests for specific package: `go test ./config`
- Run specific test: `go test -run TestConfigBool ./config`
### Building
- Build all packages: `go build ./...`
- Check module dependencies: `go mod tidy`
- Verify dependencies: `go mod verify`
### Code Quality
- Format code: `go fmt ./...`
- Vet code: `go vet ./...`
- Run static analysis: `staticcheck ./...` (if available)
## Architecture
This is a common library (`go.ntppool.org/common`) providing shared infrastructure for the NTP Pool project. The codebase emphasizes observability, security, and modern Go practices.
### Core Components
**Web Service Foundation:**
- `ekko/` - Enhanced Echo web framework with pre-configured middleware (OpenTelemetry, Prometheus, logging, security headers)
- `health/` - Standalone health check HTTP server with `/__health` endpoint
- `metricsserver/` - Prometheus metrics exposure via `/metrics` endpoint
**Observability Stack:**
- `logger/` - Structured logging with OpenTelemetry trace integration and multiple output formats
- `tracing/` - OpenTelemetry distributed tracing with OTLP export support
- `metricsserver/` - Prometheus metrics with custom registry
**Configuration & Environment:**
- `config/` - Environment-based configuration with code-generated accessors (`config_accessor.go`)
- `version/` - Build metadata and version information with Cobra CLI integration
**Security & Communication:**
- `apitls/` - TLS certificate management with automatic renewal via certman
- `kafka/` - Kafka client wrapper with TLS support for log streaming
- `xff/fastlyxff/` - Fastly CDN IP range management for trusted proxy handling
**Utilities:**
- `ulid/` - Thread-safe ULID generation with monotonic ordering
- `timeutil/` - JSON-serializable duration types
- `types/` - Shared data structures (LogScoreAttributes for NTP server scoring)
### Key Patterns
**Functional Options:** Used extensively in `ekko/` for flexible service configuration
**Interface-Based Design:** `CertificateProvider` in `apitls/` for pluggable certificate management
**Context Propagation:** Throughout the codebase for cancellation and tracing
**Graceful Shutdown:** Implemented in web servers and background services
### Dependencies
The codebase heavily uses:
- Echo web framework with custom middleware stack
- OpenTelemetry for observability (traces, metrics, logs)
- Prometheus for metrics collection
- Kafka for message streaming
- Cobra for CLI applications
### Code Generation
`config/config_accessor.go` is generated - modify `config.go` and regenerate accessors when adding new configuration options.
## Package Overview
### `apitls/`
TLS certificate management with automatic renewal support via certman. Provides a CA pool for trusted certificates and interfaces for pluggable certificate providers. Used for secure inter-service communication.
### `config/`
Environment-based configuration system with code-generated accessor methods. Handles deployment mode, hostname configuration, and TLS settings. Provides URL building utilities for web and management interfaces.
### `ekko/`
Enhanced Echo web framework wrapper with pre-configured middleware stack including OpenTelemetry tracing, Prometheus metrics, structured logging, gzip compression, and security headers. Supports HTTP/2 with graceful shutdown.
### `health/`
Standalone HTTP health check server that runs independently from the main application. Exposes `/__health` endpoint with configurable health handlers, timeouts, and graceful shutdown capabilities.
### `kafka/`
Kafka client wrapper with TLS support for secure log streaming. Provides connection management, broker discovery, and reader/writer factories with compression and batching optimizations.
### `logger/`
Structured logging system with OpenTelemetry trace integration. Supports multiple output formats (text, OTLP) with configurable log levels, systemd compatibility, and context-aware logging.
### `metricsserver/`
Dedicated Prometheus metrics HTTP server with custom registry isolation. Exposes `/metrics` endpoint with OpenMetrics support and graceful shutdown handling.
### `timeutil/`
JSON-serializable duration types that support both string parsing ("30s", "5m") and numeric nanosecond values. Compatible with configuration files and REST APIs.
### `tracing/`
OpenTelemetry distributed tracing setup with support for OTLP export via gRPC or HTTP. Handles resource detection, propagation, and automatic instrumentation with configurable TLS.
### `types/`
Shared data structures for the NTP Pool project. Currently contains `LogScoreAttributes` for NTP server scoring with JSON and SQL database compatibility.
### `ulid/`
Thread-safe ULID (Universally Unique Lexicographically Sortable Identifier) generation using cryptographically secure randomness. Optimized for simplicity and performance in high-concurrency environments.
### `version/`
Build metadata and version information system with Git integration. Provides CLI commands for Cobra and Kong frameworks, Prometheus build info metrics, and semantic version validation.
### `xff/fastlyxff/`
Fastly CDN IP range management for trusted proxy handling. Parses Fastly's IP ranges JSON file and generates Echo framework trust options for proper client IP extraction.
## Go Development Best Practices
### Code Style
- Follow standard Go formatting (`go fmt ./...`)
- Use `go vet ./...` for static analysis
- Run `staticcheck ./...` when available
- Prefer short, descriptive variable names
- Use interfaces for testability and flexibility
### Error Handling
- Always handle errors explicitly
- Use `errors.Join()` for combining multiple errors
- Wrap errors with context using `fmt.Errorf("context: %w", err)`
- Return early on errors to reduce nesting
### Testing
- Write table-driven tests when testing multiple scenarios
- Use `t.Helper()` in test helper functions
- Test error conditions, not just happy paths
- Use `testing.Short()` for integration tests that can be skipped
### Concurrency
- Use contexts for cancellation and timeouts
- Prefer channels for communication over shared memory
- Use `sync.Once` for one-time initialization
- Always call `defer cancel()` after `context.WithCancel()`
### Performance
- Use `sync.Pool` for frequently allocated objects
- Prefer slices over arrays for better performance
- Use `strings.Builder` for string concatenation in loops
- Profile before optimizing with `go tool pprof`
### Observability
- Use structured logging with key-value pairs
- Add OpenTelemetry spans for external calls
- Include trace IDs in error messages
- Use metrics for monitoring application health
### Dependencies
- Keep dependencies minimal and well-maintained
- Use `go mod tidy` to clean up unused dependencies
- Pin major versions to avoid breaking changes
- Prefer standard library when possible
### Security
- Never log sensitive information (passwords, tokens)
- Use `crypto/rand` for cryptographic randomness
- Validate all inputs at API boundaries
- Use TLS for all network communication
