Plan 10: SvelteKit Frontend Scaffold + Theme + Clients Summary

SvelteKit SPA with Catppuccin Mocha dark theme, WebSocket/HTTP clients, Svelte 5 runes state stores, and PIN login page

Performance

• Duration: 5 min
• Started: 2026-03-01T02:49:15Z
• Completed: 2026-03-01T02:54:37Z
• Tasks: 1 (single compound task with 8 sub-items)
• Files modified: 43

Accomplishments

• SvelteKit project initialized with adapter-static SPA mode, builds to frontend/build/
• Catppuccin Mocha (dark) and Latte (light) themes with 26 base colors + semantic tokens + poker-specific colors
• WebSocket client with exponential backoff reconnect (1s-30s), connection state tracking, message routing
• HTTP API client with auto JWT auth, 401 redirect to login, typed error handling
• Auth state (Svelte 5 runes) with localStorage persistence, role-based access checks
• Tournament state (Svelte 5 runes) handles clock, players, tables, financials, activity, rankings, balance
• PIN login page with large numpad buttons, masked dot display, keyboard support, error states
• Makefile updated: make frontend runs real SvelteKit build, make all builds frontend then Go binary

Task Commits

Each task was committed atomically:

1. Task J1: Initialize SvelteKit project with theme, WS client, API client, stores, login page, Makefile - 47e1f19 (feat)

Files Created/Modified

• frontend/package.json - SvelteKit project config with ESM type
• frontend/svelte.config.js - adapter-static with SPA fallback
• frontend/vite.config.ts - Vite config with SvelteKit plugin
• frontend/tsconfig.json - TypeScript config extending SvelteKit
• frontend/src/app.html - HTML shell with data-theme="mocha"
• frontend/src/app.css - Reset, touch targets, scrollbars, utilities
• frontend/src/lib/theme/catppuccin.css - Mocha/Latte themes with semantic tokens
• frontend/src/lib/ws.ts - WebSocket client with reconnect and backoff
• frontend/src/lib/api.ts - HTTP API client with JWT auth
• frontend/src/lib/stores/auth.svelte.ts - Auth state with localStorage
• frontend/src/lib/stores/tournament.svelte.ts - Tournament state with WS message handling
• frontend/src/routes/+layout.ts - SPA mode (prerender=true, ssr=false)
• frontend/src/routes/+layout.svelte - Root layout importing app.css
• frontend/src/routes/+page.svelte - Home page with auth redirect
• frontend/src/routes/login/+page.svelte - PIN login page with numpad
• Makefile - Updated frontend target for real SvelteKit build

Decisions Made

• Used CSS custom properties for Catppuccin instead of @catppuccin/palette JS package — simpler, no runtime dependency, works with data-theme attribute switching
• Added "type": "module" to package.json — required for ESM-only SvelteKit/Vite packages
• frontend/build/ tracked in git (not gitignored) — required by Go's embed.go for go:embed directive
• Defined all Catppuccin colors directly in CSS rather than importing from npm — avoids build complexity and runtime overhead

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Added "type": "module" to package.json

• Found during: Task J1 (SvelteKit build)
• Issue: Vite build failed with "This package is ESM only but it was tried to load by require"
• Fix: Added "type": "module" to frontend/package.json
• Files modified: frontend/package.json
• Verification: npm run build succeeds
• Committed in: 47e1f19

2. [Rule 3 - Blocking] Ran svelte-kit sync before build

• Found during: Task J1 (SvelteKit build)
• Issue: tsconfig.json extends .svelte-kit/tsconfig.json which doesn't exist until sync runs
• Fix: npx svelte-kit sync generates the .svelte-kit/ directory
• Files modified: None (generated files in .svelte-kit/ are gitignored)
• Verification: Build succeeds without tsconfig warning
• Committed in: 47e1f19

---

Total deviations: 2 auto-fixed (2 blocking) Impact on plan: Both fixes necessary for build to succeed. No scope creep.

Issues Encountered

• make all fails at Go build step due to pre-existing undefined types in internal/server/routes/templates.go — this is from incomplete Plan I (Template CRUD), not related to this plan's changes. make frontend works correctly.
• Go binary not available in sandbox PATH — located at /usr/local/go/bin/go. Does not affect frontend build.
• Skipped @catppuccin/palette npm dependency — defined colors directly in CSS for zero runtime overhead.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Frontend scaffold ready for Plan M (Layout Shell) and Plan N (Feature Views)
• WebSocket client ready to connect once backend WS hub is active
• API client ready for all CRUD operations once endpoints are implemented
• Auth state ready for PIN login once auth endpoint exists
• All Svelte 5 runes patterns established for future components

Self-Check: PASSED

All 17 key files verified present. Commit 47e1f19 verified in git log.
