# scrabble-game

Multiplatform Scrabble game. Players arrive from a platform (Telegram first;
later VK/MAX/iOS/Android) or from standalone web (email / guest). The game
supports English Scrabble, Russian Scrabble and Эрудит.

## Components

- **`gateway`** — the only public ingress: anti-abuse, platform authentication
  (resolves the player and injects `X-User-ID`), routing to `backend`, and an
  admin surface behind Basic Auth. *(added in a later stage)*
- **`backend`** — internal-only service that owns every domain concern and
  embeds the [`scrabble-solver`](../scrabble-solver) engine library in-process.
- **`ui`** — pure-HTML5 client (plain Svelte + Vite), embeddable in platform
  webviews and packageable to native via Capacitor. *(added in a later stage)*
- **`platform/*`** — per-platform side-services (e.g. the Telegram bot).
  *(added in a later stage)*

- [`docs/ARCHITECTURE.md`](docs/ARCHITECTURE.md) — global architecture, transport,
  security, cross-service contracts.
- [`docs/FUNCTIONAL.md`](docs/FUNCTIONAL.md) (+ [`_ru`](docs/FUNCTIONAL_ru.md)) —
  per-domain user stories.
- [`docs/TESTING.md`](docs/TESTING.md) — test layers and the per-stage CI gate.
- [`PLAN.md`](PLAN.md) — the staged implementation plan and stage tracker.
- [`CLAUDE.md`](CLAUDE.md) — project guide and the mandatory per-stage workflow.

## Build & test

```sh
go build ./backend/...  # per module (the workspace spans several modules)
go vet ./backend/...
gofmt -l .              # must print nothing
go test -count=1 ./backend/...
```

## Run the backend locally

```sh
go run ./backend/cmd/backend     # serves /healthz and /readyz on :8080
```

Configuration is read from the environment: `BACKEND_HTTP_ADDR` (default
`:8080`), `BACKEND_LOG_LEVEL` (`debug|info|warn|error`, default `info`).
