fix(dashboard): scope localStorage key by userId to prevent cross-user layout bleed (#27)
New users on a shared device were picking up a previous user's stale
(potentially empty) dashboard layout from localStorage because the key
"capakraken_dashboard_v1" was not user-scoped.
- useDashboardLayout: key is now capakraken_dashboard_v1_{userId};
userId is resolved via trpc.user.me before touching localStorage
- Initial state falls back to createDefaultDashboardLayout() until
userId resolves, then hydrates from the user-scoped key
- DB layout still wins over localStorage when it has data (unchanged)
- E2E test suite covers: new-user flow, modal widget list, add widget
persists after reload, cross-user localStorage isolation
- plan.md: added ticket #27 implementation plan

/**
|
||||
* E2E tests for the dashboard widget flow.
|
||||
*
|
||||
* Coverage:
|
||||
* 1. New user sees default dashboard with stat-cards widget
|
||||
* 2. Add Widget modal lists all available widgets
|
||||
* 3. Adding a widget persists it on the dashboard (survives page reload)
|
||||
* 4. Removing a widget removes it from the dashboard
|
||||
* 5. New user on fresh localStorage gets default layout, not another user's layout
|
||||
*
|
||||
* Design notes:
|
||||
* - Creates a temporary test user via tRPC (admin session) for isolation.
|
||||
* - Cleans up the test user in afterAll.
|
||||
* - Uses an empty storageState to ensure no cross-user localStorage bleed.
|
||||
* - localStorage key is user-scoped: "capakraken_dashboard_v1_{userId}".

## Plan: Ticket #27 — Dashboard Widget Bug (new users see empty modal)
|
||||
|
||||
### Anforderungsanalyse
|
||||
|
||||
Neue Nutzer können keine Widgets zum Dashboard hinzufügen. Root cause: `localStorage`-Key
|
||||
`"capakraken_dashboard_v1"` ist **nicht user-scoped**. Wenn User A sich ausloggt und User B
|
||||
auf demselben Gerät anmeldet, liest `useDashboardLayout` das Layout von User A aus
|
||||
`localStorage`. Hat User A ein leeres Dashboard gespeichert, sieht User B 0 Widgets —
|
||||
und nach Klick auf "Add Widget" im Modal erscheint der neue Widget **nicht** (da der
|
||||
Hydrationszustand nicht sauber initialisiert wird).
|
||||
|
||||
**Fix:** localStorage-Key auf `capakraken_dashboard_v1_{userId}` umstellen. Vor dem Zugriff
|
||||
auf `localStorage` wartet der Hook auf `trpc.user.me`, um die User-ID zu kennen.
|
||||
|
||||
### Betroffene Pakete & Dateien
|
||||
|
||||
| Paket | Datei | Art |
|
||||
|-------|-------|-----|
|
||||
| `apps/web` | `src/hooks/useDashboardLayout.ts` | edit — user-scoped storage key |
|
||||
| `apps/web` | `e2e/dev-system/dashboard-widgets.spec.ts` | create — E2E tests |
|
||||
|
||||
### Task-Liste
|
||||
|
||||
- [x] **T-1:** `useDashboardLayout` auf user-scoped localStorage umstellen → `useDashboardLayout.ts`
|
||||
- [x] **T-2:** E2E-Test für den kompletten Widget-Flow (new user, add, persist, reload) → `dashboard-widgets.spec.ts`
|
||||
- [ ] **T-3:** `pnpm --filter @capakraken/web exec tsc --noEmit` — keine neuen TS-Fehler
|
||||
- [ ] **T-4:** E2E-Tests gegen laufenden Dev-Server ausführen (manuell oder CI)
|
||||
- [ ] **T-5:** Commit + Ticket #27 auf Gitea kommentieren + `in-review` setzen
|
||||
|
||||
### Akzeptanzkriterien
|
||||
|
||||
- [ ] Neuer Admin-User sieht nach Login das Default-Dashboard (stat-cards)
|
||||
- [ ] Modal zeigt alle 11 Widgets an
|
||||
- [ ] Gewählter Widget erscheint sofort auf dem Dashboard
|
||||
- [ ] Nach Page-Reload ist der Widget weiterhin sichtbar
|
||||
- [ ] Cross-User-Bleed: User B erbt nicht das Layout von User A
