- `useCallback` for `connect` to keep the `useEffect` dependency stable
- `esRef`, `attemptsRef`, `timerRef` — all `useRef` (not state) to avoid re-render loops
- Close `es` on error before scheduling retry (prevents browser auto-reconnect stacking with manual reconnect)

## Shared Patterns
### Auth / User Resolution
**Source:** `apps/api/src/routes/events.ts` lines 5976
**Apply to:** `apps/api/src/routes/lists.ts`
```typescript
async function resolveUserId(c: any): Promise<number | null> {
const devUser = c.get('user') as { id: number } | undefined
if (devUser) return devUser.id
const devUser = c.get('user') as { id: number } | undefined;
if (devUser) return devUser.id;
const auth = await getAuth(c)
if (!auth) return null
const auth = await getAuth(c);
if (!auth) return null;
const iss = (auth.iss as string | undefined) ?? ''
const sub = auth.sub ?? ''
const displayName = deriveDisplayName(auth)
const user = await upsertUser(iss, sub, displayName)
return user?.id ?? null
const iss = (auth.iss as string | undefined) ?? '';
const sub = auth.sub ?? '';
const displayName = deriveDisplayName(auth);
const user = await upsertUser(iss, sub, displayName);
return user?.id ?? null;
}
```
Copy verbatim — do not extract to a shared module (existing convention duplicates this per router).
### Error Handling (API routes)
**Source:** `apps/api/src/routes/events.ts` (every handler's catch block)
**Apply to:** `apps/api/src/routes/lists.ts`
```typescript
try {
// ... db operations ...
return c.json({ /* result */ })
return c.json({
/* result */
});
} catch (err) {
console.error('[lists/<endpoint>] DB operation failed:', err)
return c.json({ error: 'Service unavailable' }, 503)
console.error('[lists/<endpoint>] DB operation failed:', err);
return c.json({ error: 'Service unavailable' }, 503);
}
```
Pattern: 503 on caught exceptions, not 500. `console.error` with a `[module/endpoint]` prefix tag.
### 401 Guard Pattern
**Source:** `apps/api/src/routes/events.ts` (every handler, lines 125126):
```typescript
const currentUserId = await resolveUserId(c)
if (currentUserId === null) return c.json({ error: 'Unauthorized' }, 401)
const currentUserId = await resolveUserId(c);
if (currentUserId === null) return c.json({ error: 'Unauthorized' }, 401);
```
First two lines of every protected handler.
### CSS Token Usage (PWA components)
**Source:** `apps/pwa/src/components/DeleteConfirmationDialog.tsx` (all inline styles)
**Apply to:** all new PWA components
Token set in use:
- `var(--color-surface)`, `var(--color-surface-raised)`, `var(--color-overlay)`
- `var(--color-text-primary)`, `var(--color-text-secondary)`
- `var(--color-destructive)`, `var(--color-border)`
@@ -688,44 +731,56 @@ Token set in use:
- Minimum touch target: `minHeight: '44px'` (buttons/rows)
### Fetch with Credentials (PWA API client)
**Source:** `apps/pwa/src/api/client.ts` lines 3639
**Apply to:** `apps/pwa/src/api/listsClient.ts`
```typescript
const res = await fetch('/api/...', {
credentials: 'include',
redirect: 'manual', // only for /api/me; not required for data endpoints
})
});
```
All list API calls use `credentials: 'include'`. `redirect: 'manual'` is only needed for the initial session check (`/api/me`) — not for list CRUD endpoints.
### TanStack Query Keys
**Apply to:** `apps/pwa/src/routes/ListsIndex.tsx`, `apps/pwa/src/routes/ListDetail.tsx`
```typescript
// List of lists
queryKey: ['lists']
queryKey: ['lists'];
// Items for a specific list
queryKey: ['list', listId] // listId is a number
queryKey: ['list', listId]; // listId is a number
```
Invalidate `['lists']` after create/delete list. Invalidate `['list', listId]` after any item mutation or SSE event for that list.
### Lucide Icons (PWA)
**Source:** `apps/pwa/src/components/DeleteConfirmationDialog.tsx` line 27, CalendarShell.tsx line 43
**Apply to:** all new PWA components
```tsx
import { Trash2 } from 'lucide-react'
import { Trash2 } from 'lucide-react';
// Usage: <Trash2 size={16} aria-hidden="true" />
```
Always pass `aria-hidden="true"` to decorative icons. Use `size={16}` for inline/dense contexts, `size={22}` for navigation tabs.
### Zustand Store Shape
**Source:** `apps/pwa/src/store/calendarStore.ts`
**Apply to:** `apps/pwa/src/store/listsStore.ts`
- Use `create<StoreInterface>()((set) => ({ ... }))` — no `persist`, no `immer`
- Actions are inline setter functions, not separate files
- UI-only state: no server data, no async in store actions (mutations live in components via `useMutation`)
### Plain-text XSS Guard (PWA)
**Source:** `apps/pwa/src/components/DeleteConfirmationDialog.tsx` (comment `/* Plain text — XSS guard */` on every text node, line 133 etc.)
**Apply to:** all new PWA components that render user-supplied strings (list names, item text)
