Full stack swap to enable future extension (more pages / load functions /
backend) while keeping JSDoc-only code style.
Stack:
- SvelteKit 2 + adapter-static
- Svelte 5 runes ($state, $derived, $effect, $props)
- Vite 7 + @sveltejs/vite-plugin-svelte 6
- Tailwind 4 (Vite plugin)
- ESLint 9 (flat) + eslint-plugin-svelte
- Pure JS + JSDoc, no TypeScript
Source moves:
- app/page.jsx → src/routes/+page.svelte
- app/master/page.jsx → src/routes/master/+page.svelte
- app/layout.jsx → src/routes/+layout.svelte (+ +layout.js)
- components/player-board.jsx → src/lib/PlayerBoard.svelte
- lib/game-logic.js → src/lib/game-logic.js (verbatim)
- next.config.mjs → svelte.config.js + vite.config.js
- app/globals.css → src/app.css
- (new) → src/app.html
Behavior preserved: PlayerBoard with bingo "Kinh!" popup + waiting "Chờ X"
toast, master 9x10 tracking board with shuffled draw, host's own player
card via storagePrefix="loto_master_card", localStorage prefix model
(loto_*, loto_master, loto_master_card_*), basePath dual mode (CF default
empty, BUILD_PROFILE=gh → /loto, codeserver dev → /absproxy/{port}).
A11y kept from prior hardening: role-correct buttons, aria-pressed on
cells, role=dialog modal with Escape, role=status toast.
Plans: ts-to-jsdoc plan marked completed; sveltekit-refactor plan tracks
the work above. Docs under ./docs/ rewritten by docs-manager subagent to
match the SvelteKit terminology.

# Codebase Summary
|
||
|
||
## File Organization
|
||
|
||
### Routing & Layout
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/routes/+layout.svelte` | Root HTML layout. Sets Vietnamese lang, imports Geist font, applies global flex layout. |
|
||
| `src/routes/+page.svelte` | Player page (`/`). Instructions toggle, PlayerBoard component, indigo gradient branding. |
|
||
| `src/routes/master/+page.svelte` | Host page (`/master`). Controls (new game, draw number), 9×10 master board, host's player card. |
|
||
|
||
### Shared Components
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/PlayerBoard.svelte` | Reusable player card (9×9 grid). Handles crossed state, bingo popup, "Chờ X" toast. Accepts `storagePrefix` prop for multi-card isolation. |
|
||
|
||
### Game Logic
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/game-logic.js` | Stateless utilities: generateGrid (weighted column selection), saveGrid, loadGrid, saveCrossedState, loadCrossedState, isRowComplete, getWaitingNumber. |
|
||
|
||
### Styling
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/app.css` | Root styles: Tailwind @import, CSS variables (light/dark), `.loto-grid` & `.master-grid` (9-col), animations (fade-in, pop-in, bounce-slow, spin-slow, toast), `.cell-crossed` diagonal. |
|
||
|
||
### Configuration
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `svelte.config.js` | adapter-static (HTML export), dual basePath via BUILD_PROFILE env. |
|
||
| `vite.config.js` | Tailwind + SvelteKit plugins. codeserver HMR config (port, allowedHosts, hmr). |
|
||
| `package.json` | SvelteKit 2, Svelte 5 (runes), Tailwind 4, Vite. Scripts: dev, dev:codeserver, build, build:gh, lint. |
|
||
| `eslint.config.mjs` | ESLint 9 flat config (@eslint/js + eslint-plugin-svelte). |
|
||
| `jsconfig.json` | Path alias `$lib`, no checkJs. |
|
||
| `.gitignore` | Excludes node_modules, build, .env.local, etc. |
|
||
| `.env.example` | codeserver profile vars (CODESERVER_HOST, CODESERVER_PORT). |
|
||
|
||
## Key Data Structures
|
||
|
||
**Grid**: 9×9 2D array of numbers (1–90). Empty cells are 0.
|
||
**Crossed**: 9×9 2D array of booleans indicating marked cells.
|
||
**Master State**: `{ called: number[], remaining: number[] }` — drawn and undrawn numbers.
|
||
|
||
## Storage Keys (localStorage)
|
||
|
||
| Key | Use Case |
|
||
|-----|----------|
|
||
| `loto_grid` | Player's card numbers. |
|
||
| `loto_crossed` | Player's marked cells. |
|
||
| `loto_master` | Host's drawn/remaining numbers. |
|
||
| `loto_master_card_grid` | Host's player card numbers. |
|
||
| `loto_master_card_crossed` | Host's marked cells. |
|
||
|
||
