# Contributing to hnh-map
## Getting started
Clone the repository and run the project locally (see [Development](docs/development.md)):
- **Option A:** Docker Compose for development: `docker compose -f docker-compose.dev.yml up` (or `make dev`). Frontend on 3000, backend on 3080.
- **Option B:** Run Go backend from the repo root (`go run ./cmd/hnh-map -grids=./grids -port=8080`) and Nuxt separately (`cd frontend-nuxt && npm run dev`). Ensure the frontend can reach the backend (proxy or same host).
## Code layout
The backend follows a layered architecture: **Store → Services → Handlers**.
- **Backend:** Entry point is `cmd/hnh-map/main.go`. Application logic lives in `internal/app/`:
- `app.go``App` struct, domain types, SPA serving, constants.
- `router.go` — route registration.
- `topic.go` — pub/sub for real-time updates.
- `migrations.go` — database migrations.
- `store/` — bbolt database access layer (`db.go`, `buckets.go`).
- `services/` — business logic (`auth.go`, `map.go`, `admin.go`, `client.go`, `export.go`).
- `handlers/` — HTTP handlers (`api.go`, `auth.go`, `map.go`, `client.go`, `admin.go`, `tile.go`, `handlers.go`, `response.go`).
- `apperr/` — domain error types.
- `response/` — shared JSON response helpers.
- **Frontend:** Nuxt 3 app in `frontend-nuxt/` (pages, components, composables, layouts, plugins, `public/gfx`). It is served by the Go backend at root `/` with baseURL `/`.
## Formatting, linting, and tests
Use Makefile targets for common tasks:
```bash
make fmt # Format all code (Go + frontend)
make lint # Run Go linter (golangci-lint) and frontend ESLint
make test # Run Go tests
```
Or run manually:
- Go: `go fmt ./...` and `golangci-lint run`
- Frontend: `npm --prefix frontend-nuxt run lint` and `npm --prefix frontend-nuxt run format`
- Tests: `go test ./...`
Always format and lint before committing. Add or update tests if you change behaviour.
## Submitting changes
- Open a pull request with a clear description of the change.
- Mention compatibility with [hnh-auto-mapper-server](https://github.com/APXEOLOG/hnh-auto-mapper-server) if relevant (e.g. client protocol or API).
