## 🎨 Design Principles Achieved
|
||||
|
||||
### 1. Separation of Concerns ✓
|
||||
- **Hooks** = Business logic
|
||||
- **Components** = Presentation
|
||||
- **JSON** = Structure & configuration
|
||||
|
||||
### 2. Component Size Limit ✓
|
||||
- All new hooks < 150 LOC
|
||||
- Orchestration files < 85 LOC
|
||||
- Focused, single-responsibility
|
||||
|
||||
### 3. Type Safety ✓
|
||||
- Full TypeScript support
|
||||
- Zod schema validation
|
||||
- Runtime type checking
|
||||
|
||||
### 4. Composability ✓
|
||||
- Hooks combine naturally
|
||||
- Actions chain together
|
||||
- Components nest recursively
|
||||
|
||||
### 5. Testability ✓
|
||||
- Hooks testable in isolation
|
||||
- JSON schemas validate independently
|
||||
- Mock-friendly architecture
|
||||
|
||||
## 📈 Benefits Realized
|
||||
|
||||
### For Developers
|
||||
- **Faster development**: Reuse hooks across features
|
||||
- **Less code**: JSON replaces boilerplate React
|
||||
- **Better organization**: Clear structure and boundaries
|
||||
- **Easier debugging**: Small, focused units
|
||||
- **Type safety**: Catch errors at compile time
|
||||
|
||||
### For the Application
|
||||
- **More maintainable**: Changes isolated to hooks or JSON
|
||||
- **More flexible**: New pages without new code
|
||||
- **More testable**: Small units easy to test
|
||||
- **Better performance**: Optimized re-renders
|
||||
- **Scalable**: Add features without complexity growth
|
||||
|
||||
### For Users
|
||||
- **More reliable**: Tested, reusable components
|
||||
- **Faster**: Performance-optimized architecture
|
||||
- **Consistent**: Shared logic ensures consistency
|
||||
|
||||
## 🚀 Usage Examples
|
||||
|
||||
### Example 1: Using Hooks
|
||||
|
||||
```typescript
|
||||
import { useArray, useSearch, useSort } from '@/hooks/data'
|
||||
import { useSelection, useDialog } from '@/hooks/ui'
|
||||
|
||||
function ProductManager() {
|
||||
const { items: products, add, remove } = useArray('products', [])
|
||||
const { results, query, setQuery } = useSearch(products, ['name', 'category'])
|
||||
const { sortedItems, toggleSort } = useSort(results, 'name')
|
||||
const selection = useSelection()
|
||||
const dialog = useDialog()
|
||||
|
||||
return (
|
||||
<div>
|
||||
<Input value={query} onChange={(e) => setQuery(e.target.value)} />
|
||||
{/* Rest of component */}
|
||||
</div>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
### Example 2: JSON-Driven Page
|
||||
|
||||
```json
|
||||
{
|
||||
"id": "products",
|
||||
"name": "Product Manager",
|
||||
"layout": { "type": "single" },
|
||||
"dataSources": [
|
||||
{
|
||||
"id": "products",
|
||||
"type": "kv",
|
||||
"key": "products-list",
|
||||
"defaultValue": []
|
||||
}
|
||||
],
|
||||
"components": [
|
||||
{
|
||||
"id": "root",
|
||||
"type": "Card",
|
||||
"children": [/* ... */]
|
||||
}
|
||||
],
|
||||
"actions": [
|
||||
{
|
||||
"id": "add-product",
|
||||
"type": "create",
|
||||
"target": "products"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Example 3: Hook Composition
|
||||
|
||||
```typescript
|
||||
function useProductList() {
|
||||
// Compose multiple hooks
|
||||
const { items, add, remove, update } = useArray('products', [])
|
||||
const { results, setQuery } = useSearch(items, ['name'])
|
||||
const { sortedItems, toggleSort } = useSort(results, 'name')
|
||||
const { items: paged, ...pagination } = usePagination(sortedItems, 10)
|
||||
|
||||
return {
|
||||
products: paged,
|
||||
add,
|
||||
remove,
|
||||
update,
|
||||
search: setQuery,
|
||||
sort: toggleSort,
|
||||
pagination,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🔄 Migration Path
|
||||
|
||||
### Phase 1: Setup (Done ✓)
|
||||
- [x] Create hook library structure
|
||||
- [x] Build orchestration engine
|
||||
- [x] Write documentation
|
||||
- [x] Create examples
|
||||
|
||||
### Phase 2: Gradual Migration (Next Steps)
|
||||
1. Identify large components (>150 LOC)
|
||||
2. Extract business logic to hooks
|
||||
3. Convert static pages to JSON
|
||||
4. Test thoroughly
|
||||
5. Remove old code
|
||||
|
||||
### Phase 3: Full Adoption
|
||||
- All new features use hooks + JSON
|
||||
- Existing features migrated iteratively
|
||||
- Complex logic in custom hooks
|
||||
- Simple pages in JSON
