# CHAPTER 14 SUMMARY

## Key Concepts Introduced
1. **React Hooks** - useTypedFetch, useTypedMutation, useInfiniteTypedFetch - Used in chapters: 15
2. **Vue Composables** - Composition API integration with TypedFetch - Used in chapters: 15
3. **Svelte Stores** - Reactive stores for TypedFetch data - Used in chapters: 15
4. **Angular Services** - RxJS observables wrapping TypedFetch - Used in chapters: 15
5. **Framework Detection** - Auto-configure based on framework - Used in chapters: 15
6. **Lifecycle Management** - Proper cleanup across frameworks - Used in chapters: 15
7. **State Management** - Framework-specific state patterns - Used in chapters: 15
8. **Form Integration** - Forms with validation across frameworks - Used in chapters: 15
9. **Real-time Updates** - SSE/WebSocket framework integration - Used in chapters: 15
10. **Optimistic Updates** - UI updates before server confirmation - Used in chapters: 15

## Code Patterns Established
```typescript
// Pattern 1: React hooks
const { data, loading, error } = useTypedFetch('/api/data')

// Pattern 2: Vue composables
const { data, execute } = useTypedFetch(url, { immediate: false })

// Pattern 3: Svelte stores
const store = createFetchStore('/api/data')
$: data = $store.data

// Pattern 4: Angular observables
data$ = this.tf.get('/api/data').pipe(shareReplay(1))
```

## Framework Integrations
- React: Custom hooks with automatic refetch and caching
- Vue: Composition API with reactive refs
- Svelte: Stores with automatic subscriptions
- Angular: RxJS observables with operators
- All frameworks: TypeScript types preserved

## Advanced Patterns Introduced
1. **Infinite Scroll** - Load more data as user scrolls
2. **Polling** - Regular data updates at intervals
3. **Debounced Search** - Efficient search implementations
4. **Pagination** - Page-based data loading
5. **Request Deduplication** - Prevent duplicate requests
6. **SSR Support** - Server-side rendering compatibility

## Building Blocks for Next Chapter
- Learned: Framework integration patterns
- Mastered: Lifecycle management and state
- Ready for: Future HTTP protocols and AI

## Weather Buddy App Status
- Version 14.0: Works in any framework
- React hooks for React apps
- Vue composables for Vue apps
- Svelte stores for Svelte apps
- Angular services for Angular apps
- Next: Future protocols (Chapter 15)

## Best Practices Established
1. Respect framework idioms
2. Handle lifecycle cleanup
3. Maintain type safety
4. Optimize for framework
5. Share code wisely
6. Test integrations
7. Document patterns

## Common Mistakes to Avoid
- Fighting framework patterns
- Memory leaks from no cleanup
- Over-abstracting simple things
- Ignoring SSR requirements
- Large bundle sizes
- Losing TypeScript types
