## 🎯 Common Patterns Across All Pages

### 1. React Query Integration
**All pages use proper typing:**
```typescript
const { data, isLoading, error } = useQuery<Type>({
  queryKey: ['key'],
  queryFn: apiFunction,
});
```

### 2. Mutation Handling
```typescript
const createMut = useMutation({
  mutationFn: (payload: Type) => apiCall(payload),
  onSuccess: (data) => { /* typed data */ },
  onError: (e: any) => { /* error handling */ },
});
```

### 3. Form State Management
```typescript
const [editing, setEditing] = useState<Type | null>(null);
```

### 4. Modal Patterns
```typescript
const { isOpen, onOpen, onClose } = useDisclosure();
```

### 5. Toast Notifications
```typescript
toast({
  title: 'Success',
  description: 'Action completed',
  status: 'success',
});
```

## ⚠️ Minor Observations (Non-Breaking)

### 1. Type Assertions
**Pattern Used**: `(editing as any)`

**Files**: ArticlesAdminPage.tsx, MatchesAdminPage.tsx, others

**Impact**: None - works correctly  
**Recommendation**: Could define stricter interfaces  
**Priority**: Very Low (cosmetic)

**Example**:
```typescript
// Current (works fine)
const value = (editing as any)?.field;

// Could be (slightly better)
interface EditingState extends BaseType {
  field?: string;
}
const value = editing?.field;
```

### 2. `any` Type Usage
**Found in**: ~10 pages for API responses

**Pattern**:
```typescript
const response = await api.get('/endpoint');
// response.data is 'any'
```

**Impact**: None - runtime validation exists  
**Recommendation**: Create response interfaces  
**Priority**: Very Low

## 🎨 Code Quality Highlights

### Excellent Practices Found:

1. ✅ **Consistent Patterns** - All pages follow same structure
2. ✅ **Error Boundaries** - Try-catch everywhere
3. ✅ **Loading States** - Proper Skeleton components
4. ✅ **Empty States** - User-friendly messages
5. ✅ **Validation** - Client-side validation before API calls

## 🔧 Advanced TypeScript Features Used

### 1. Generic Types
```typescript
const { data } = useQuery<AnalyticsData>({...});
```

### 2. Union Types
```typescript
role: 'admin' | 'editor'
```

### 3. Partial Types
```typescript
type Editing = Partial<Player> & { id?: number };
```

### 4. Type Guards
```typescript
if (typeof value === 'number' && Number.isFinite(value))
```

### 5. Conditional Types
```typescript
isRequired={!selectedUser}
```
