# Schema Conversion Summary

## Overview
Successfully converted TypeScript schema files to JSON format with extracted compute functions.

## Files Created

### JSON Schemas
1. **`src/schemas/analytics-dashboard.json`** - Converted from `dashboard-schema.ts`
   - Contains the analytics dashboard with user management
   - Compute functions: `computeFilteredUsers`, `computeStats`, `updateFilterQuery`, `transformFilteredUsers`, `transformUserList`

2. **`src/schemas/todo-list.json`** - Split from `page-schemas.ts`
   - Todo list application schema
   - Compute functions: `computeTodoStats`, `updateNewTodo`, `computeAddTodo`, `checkCanAddTodo`

3. **`src/schemas/dashboard-simple.json`** - Split from `page-schemas.ts`
   - Simple dashboard with static stats
   - No compute functions (pure static data)

4. **`src/schemas/new-molecules-showcase.json`** - Split from `page-schemas.ts`
   - Showcase of new molecular components
   - No compute functions (pure static data)

### TypeScript Support Files
5. **`src/schemas/compute-functions.ts`** - Exported compute functions
   - `computeFilteredUsers` - Filters users by search query
   - `computeStats` - Calculates user statistics (total, active, inactive)
   - `computeTodoStats` - Calculates todo statistics (total, completed, remaining)
   - `computeAddTodo` - Creates new todo item
   - `updateFilterQuery` - Event handler for filter input
   - `updateNewTodo` - Event handler for todo input
   - `checkCanAddTodo` - Condition checker for add button
   - `transformFilteredUsers` - Transform function for badge display
   - `transformUserList` - Transform function for rendering user cards

6. **`src/schemas/schema-loader.ts`** - Hydration utility
   - `hydrateSchema()` - Converts JSON schemas to runtime schemas
   - Replaces string function identifiers with actual functions
   - Handles compute functions in dataSources, events, actions, and bindings

## Updated Files

### Component Files
- **`src/components/DashboardDemoPage.tsx`**
  - Changed from importing TS schema to importing JSON + hydration
  
- **`src/components/JSONUIShowcasePage.tsx`**
  - Changed from importing TS schemas to importing JSON + hydration

### Configuration
- **`tsconfig.json`**
  - Added `"resolveJsonModule": true` to enable JSON imports

### Documentation
- **`docs/ARCHITECTURE.md`** - Updated file structure and example code
- **`docs/JSON_UI_GUIDE.md`** - Updated references to schema files
- **`docs/IMPLEMENTATION_SUMMARY.md`** - Updated file list
- **`docs/JSON_UI_ENHANCEMENT_SUMMARY.md`** - Updated schema file name

## How It Works

### 1. JSON Schema Format
Compute functions are represented as string identifiers in JSON:
```json
{
  "id": "stats",
  "type": "computed",
  "compute": "computeStats",
  "dependencies": ["users"]
}
```

### 2. Hydration Process
The `hydrateSchema()` function replaces string identifiers with actual functions:
```typescript
import { hydrateSchema } from '@/schemas/schema-loader'
import analyticsDashboardJson from '@/schemas/analytics-dashboard.json'

const schema = hydrateSchema(analyticsDashboardJson)
```

### 3. Usage in Components
```typescript
export function DashboardDemoPage() {
  return <PageRenderer schema={schema} />
}
```

## Benefits

1. **Pure JSON** - Schemas are now pure JSON files, making them easier to:
   - Store in databases
   - Transmit over APIs
   - Edit with JSON tools
   - Version control and diff

2. **Separation of Concerns** - Logic is separated from structure:
   - JSON defines the UI structure
   - TypeScript contains the compute logic
   - Schema loader connects them at runtime

3. **Type Safety** - TypeScript functions remain type-safe and testable

4. **Maintainability** - Compute functions are centralized and reusable

## Old Files (Can be removed)
- `src/schemas/dashboard-schema.ts` (replaced by `analytics-dashboard.json`)
- `src/schemas/page-schemas.ts` (split into 3 JSON files)

Note: Keep `src/schemas/ui-schema.ts` as it contains Zod validation schemas, not UI schemas.

## Testing
- Build completed successfully with `npm run build`
- All TypeScript errors resolved
- JSON imports working correctly
