dance-lessons-coach
Go web service demonstrating idiomatic package structure, versioned JSON API, and production-ready features.
Features
- Versioned JSON API (
/api/v1,/api/v2) - Chi router with graceful shutdown
- Zerolog structured logging (console and JSON modes)
- Viper configuration (file + env vars)
- Readiness endpoint for Kubernetes / service mesh
- OpenTelemetry / Jaeger distributed tracing
- OpenAPI / Swagger UI (embedded in binary, source of truth at
/swagger/doc.json) - Username + password authentication with JWT (rotating secrets)
- Passwordless magic-link authentication (email-delivered, ADR-0028 Phase A)
- OIDC authentication with PKCE (multi-provider, ADR-0028 Phase B)
- PostgreSQL user persistence with GORM
- BDD + unit tests (Godog)
- Mistral autonomous PR pattern (cf. documentation/MISTRAL-AUTONOMOUS-PATTERN.md)
Quick Start
git clone https://gitea.arcodange.lab/arcodange/dance-lessons-coach.git
cd dance-lessons-coach
./scripts/build.sh # produces ./bin/server and ./bin/greet
./scripts/start-server.sh start
curl http://localhost:8080/api/health
curl http://localhost:8080/api/v1/greet/Alice
Stop: ./scripts/start-server.sh stop
Greet CLI
go run ./cmd/greet # Hello world!
go run ./cmd/greet Alice # Hello Alice!

API
The full interactive list is in the Swagger UI at /swagger/ (source of truth at /swagger/doc.json). Most-used endpoints :
| Method | Path | Description |
|---|---|---|
| GET | /api/health |
Liveness check |
| GET | /api/ready |
Readiness check (503 during shutdown) |
| GET | /api/version |
Version info |
| GET | /api/v1/greet/{name} |
Named greeting |
| POST | /api/v1/auth/login |
Login (JWT) |
| POST | /api/v1/auth/magic-link/request |
Passwordless magic-link |
| GET | /api/v1/auth/oidc/{provider}/start |
OIDC login |
| GET | /swagger/ |
Swagger UI |
This decision is intentional : the markdown table drifts ; swagger.json doesn't (it's regenerated from swag annotations on every build). Curated short list here for discovery, swagger for completeness.
Testing
go test ./... # unit + integration tests
./scripts/test-graceful-shutdown.sh # lifecycle + JSON logging validation
./scripts/test-opentelemetry.sh # tracing end-to-end
Gitea Client
AI agent helper script at .vibe/skills/gitea-client/scripts/gitea-client.sh.
Auth setup:
echo "your_token" > ~/.gitea_token
chmod 600 ~/.gitea_token
export GITEA_API_TOKEN_FILE="$HOME/.gitea_token"
Get a token at https://gitea.arcodange.lab → Profile → Settings → Applications.
