# Cache Automation Summary

## What Was Implemented

Complete automation of Hive cache setup for Zuraffa's caching system.

## Generated Files

When using `--cache` with `--di`:

```
lib/src/cache/
├── hive_registrar.dart              # @GenerateAdapters for all entities
├── {entity}_cache.dart              # Opens entity box
├── timestamp_cache.dart             # Opens timestamps box
├── {policy}_cache_policy.dart       # Fully implemented cache policy
└── index.dart                       # initAllCaches() + exports
```

## Key Features

### 1. Hive Registrar
- Auto-generates `@GenerateAdapters` annotation with all cached entities
- Provides `Hive.registerAdapters()` extension method
- Supports both `HiveInterface` and `IsolatedHiveInterface`
- Properly converts snake_case entity names to PascalCase

### 2. Cache Policy Files
- Separate file per policy type to avoid conflicts
- `daily_cache_policy.dart` - Shared across all entities using daily policy
- `app_restart_cache_policy.dart` - Shared across all entities using restart policy
- `ttl_<N>_minutes_cache_policy.dart` - Unique per TTL duration
- Full Hive implementation with timestamp box operations

### 3. Cache Init Files
- One per entity: `{entity}_cache.dart`
- Opens Hive box for the entity
- `timestamp_cache.dart` for cache policy timestamps
- `index.dart` with `initAllCaches()` function

### 4. CLI Enhancements
- `--ttl=<minutes>` flag for custom TTL duration (default: 1440 = 24 hours)
- Simplified next steps: just run `dart run build_runner build`

### 5. Type Safety Improvements
- DataRepository uses abstract `DataSource` type for remote datasource
- Allows easy switching between implementations (remote, mock, etc.)
- `--use-mock` now works with `--cache`

### 6. Bug Fixes
- Enum mock data uses `seed % 2` instead of `seed % 3` (prevents index errors)
- Snake case entity names properly converted to PascalCase

## User Workflow

### Before (Manual)
1. Generate code with `--cache`
2. Add `@HiveType` and `@HiveField` annotations to entities
3. Run `dart run build_runner build`
4. Manually register adapters in main.dart
5. Manually open Hive boxes
6. Manually implement cache policies
7. Wire everything together

### After (Automated)
1. Generate code with `--cache --di`
2. Run `dart run build_runner build`
3. Call `initAllCaches()` in main.dart

## Example

```bash
# Generate with cache
zfa generate Product --methods=get,getList --repository --data --cache --cache-policy=ttl --ttl=30 --di
```

```dart
// main.dart
import 'package:hive_ce_flutter/hive_ce_flutter.dart';
import 'src/cache/index.dart';
import 'src/di/index.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  
  await Hive.initFlutter();
  await initAllCaches();  // ✅ One line
  
  setupDependencies(GetIt.instance);
  
  runApp(MyApp());
}
```

## Documentation Updates

- ✅ CHANGELOG.md - Added [Unreleased] section
- ✅ README.md - Added Cache Initialization section
- ✅ README.md - Added `--ttl` flag to CLI table
- ✅ website/docs/features/caching.md - Added automatic setup section
- ✅ CACHE_INIT.md - Standalone documentation file

## Benefits

1. **Zero Boilerplate** - No manual adapter registration
2. **Type Safe** - Compile-time checks for all adapters
3. **Conflict Free** - Separate policy files per configuration
4. **Maintainable** - Auto-regenerates when entities change
5. **Testable** - Easy to switch between mock and real implementations
