Remove the under-board status strip and relocate its signals: - bag count -> a badge on the exchange/pass control + the foot of the move table - whose-turn / win-lose -> a thin strip above the score plaques - the tentative-move caption -> the board itself: staged tiles tint green (legal) or pink (illegal), the board tiles a formed word runs through go a shade darker, and an orange score badge sits on the main word (digit sized like a tile value, clamped on-board) The word geometry (covered cells + badge anchor) is a new pure client-side helper (ui/src/lib/formed.ts), independent of the move evaluator, so it works on the local or network preview path alike; the badge's number still comes from the preview score. Rack: a seven-column grid filling the tray width in both layouts — square, full-width tiles — with the confirm control in the fixed 7th slot. Settings: a touch-only "Zoom the board" toggle (default on, device-local) gates the tile-placement auto-zoom; taking a hint while zoomed in now zooms out so the highlighted hint word is never left off-screen. Docs (FUNCTIONAL +_ru, UI_DESIGN, ARCHITECTURE) and e2e/unit tests updated.
scrabble-ui
Pure-HTML5 game client — plain Svelte 5 (runes) + TypeScript + Vite, no
SvelteKit. Talks to the gateway over Connect-RPC + FlatBuffers; embeddable in
platform webviews and packageable to native via Capacitor.
The playable slice: sign in (guest / email), the "my games" lobby, auto-match, the board (place tiles by drag or tap, pass, exchange, resign), hint, word-check + complaint, per-game chat and nudge, the live in-app stream, i18n (en/ru), theme, and the profile. Social surfaces add friends/blocks (with one-time friend codes), friend-game invitations, profile editing + email binding, the statistics screen, the lobby notification badge, and the in-game history + GCG export (share or download, finished games only).
Scripts
pnpm install
pnpm start # mock mode (VITE_MOCK): lobby -> game with no backend, :5173
pnpm dev # against a running gateway (Vite proxies /scrabble.edge.v1.Gateway -> :8081)
pnpm check # svelte-check / tsc
pnpm test:unit # Vitest (pure logic + FlatBuffers codec)
pnpm test:e2e # Playwright smoke against the mock
pnpm build # static bundle into dist/ (prod app ~97 KB gzip JS; per-chunk budget: scripts/bundle-size.mjs)
pnpm codegen # regenerate src/gen from edge.proto + scrabble.fbs (dev-time)
GATEWAY_URL overrides the dev proxy target; VITE_GATEWAY_URL sets the runtime
gateway origin for a packaged (non-proxied) build. VITE_TELEGRAM_BOT_ID
enables the "Link Telegram" web sign-in (the Login Widget) — inert until the site
domain is registered with BotFather (/setdomain); VITE_TELEGRAM_LINK is the
friend-invite Mini App link for the single bot (full URL https://t.me/<bot>/<app>).
VITE_TELEGRAM_GAME_CHANNEL_NAME is the "Play in Telegram" link shown on the landing page.
The build has two entries: the game SPA (index.html, served at /app/ and
/telegram/) and a lightweight landing page (landing.html, served at /).
How it talks to the gateway
A single Connect Execute(message_type, payload) carries every unary op; the request
and response bodies are FlatBuffers tables (pkg/fbs/scrabble.fbs) in payload.
The session token rides in Authorization: Bearer; a domain failure comes back in
result_code. Subscribe is the live event stream; its game events carry a state delta
that lib/gamedelta.ts applies to the per-game cache (lib/gamecache.ts), so a move renders without
a follow-up game.state (a gap falls back to a refetch). lib/transport.ts is the real
client; lib/mock/ is an in-memory fake selected by MODE === 'mock' (and tree-shaken
out of production). Both speak the plain lib/model.ts types via lib/codec.ts.
No board on the wire: StateView is a summary + rack only, so the client
reconstructs the 15×15 board by replaying the decoded move journal (game.history).
The play loop is alphabet-agnostic: the rack and the play / exchange /
word-check requests carry alphabet indices, and the client caches each variant's
(index, letter, value) table — sent once behind StateRequest.include_alphabet — in
lib/alphabet.ts, rendering the rack and blank chooser from it. Premium squares
(lib/premiums.ts) stay a client-side geometry map ported from
scrabble-solver/rules/rules.go (pinned by a Vitest parity test); tile values and the
alphabet now come from the server table (their parity lives in the Go engine.AlphabetTable
test). Board, tiles and effects are pure CSS + Unicode — no image/font/SVG assets.
Codegen
src/gen/ is committed; CI builds it, it is not regenerated there (the same model
as the Go committed jet/fbs output). pnpm codegen runs flatc --ts on
../pkg/fbs/scrabble.fbs and buf generate (protoc-gen-es) on the edge proto. Needs
flatc 23.5.26 and buf on PATH.
Theming
Design tokens are CSS custom properties (src/app.css); light/dark follows
prefers-color-scheme or an explicit choice in Settings. The token system is
Telegram-themeParams-ready (lib/theme.ts) — a Mini App can override the tokens at
runtime; the Telegram SDK itself is wired in the Telegram stage.
