This provides flexibility for users who have separate ObjectQL implementations or need custom configuration. - -## What Changed - -### 1. New Files - -#### `packages/runtime/src/objectql-plugin.ts` -- **Purpose**: Runtime plugin for ObjectQL engine registration -- **Key Features**: - - Implements `RuntimePlugin` interface - - Accepts optional custom ObjectQL instance - - Supports custom host context configuration - - Registers ObjectQL during the install phase - -#### `packages/runtime/README.md` -- **Purpose**: Documentation for the runtime package -- **Contents**: - - Usage examples for both plugin-based and backward-compatible approaches - - API reference for ObjectStackKernel and ObjectQLPlugin - - Migration guide from hardcoded to plugin-based registration - -#### `examples/custom-objectql-example.ts` -- **Purpose**: Demonstrates custom ObjectQL instance usage -- **Shows**: - - How to create a custom ObjectQL instance - - How to pre-configure hooks - - How to pass custom host context - -### 2. Modified Files - -#### `packages/runtime/src/kernel.ts` -- **Changes**: - - Changed `ql` property from direct initialization to deferred (using `!` assertion) - - Added plugin detection logic in constructor - - Maintains backward compatibility by auto-initializing ObjectQL if no plugin detected - - Added warning message for backward compatibility mode - -#### `packages/runtime/src/index.ts` -- **Changes**: - - Added export for `ObjectQLPlugin` - -#### `examples/host/src/index.ts` -- **Changes**: - - Updated to use `ObjectQLPlugin()` in the plugins array - - Added comments showing both default and custom usage options - -#### `examples/host/debug-registry.ts` -- **Changes**: - - Updated to use `ObjectQLPlugin()` for consistency - -#### `examples/msw-react-crud/src/mocks/browser.ts` -- **Changes**: - - Updated to use `ObjectQLPlugin()` in the plugins array - -## Technical Design - -### Plugin Detection Logic - -```typescript -const hasObjectQLPlugin = plugins.some(p => - p && typeof p === 'object' && 'install' in p && p.name?.includes('objectql') -); -``` - -This detection: -- Checks for object type -- Verifies `install` method exists -- Matches plugin name containing 'objectql' - -### Installation Flow - -1. **Construction Phase**: Kernel constructor checks for ObjectQLPlugin -2. **Install Phase**: ObjectQLPlugin.install() attaches ObjectQL to kernel -3. **Start Phase**: Kernel uses the registered ObjectQL instance - -### Backward Compatibility - -If no ObjectQLPlugin is detected: -- Kernel auto-initializes ObjectQL with default settings -- Warning message suggests using ObjectQLPlugin -- Existing code continues to work without changes - -## Usage Patterns - -### Pattern 1: Default ObjectQL (Recommended) - -```typescript -const kernel = new ObjectStackKernel([ - new ObjectQLPlugin(), - // ... other plugins -]); -``` - -### Pattern 2: Custom ObjectQL Instance - -```typescript -const customQL = new ObjectQL({ env: 'production' }); -const kernel = new ObjectStackKernel([ - new ObjectQLPlugin(customQL), - // ... other plugins -]); -``` - -### Pattern 3: Backward Compatible (Legacy) - -```typescript -// Still works, shows warning -const kernel = new ObjectStackKernel([ - // ... plugins without ObjectQLPlugin -]); -``` - -## Benefits - -1. **Flexibility**: Users can provide custom ObjectQL implementations -2. **Separation of Concerns**: ObjectQL is now a first-class plugin -3. **Testability**: Easier to mock or replace ObjectQL for testing -4. **Explicit Dependencies**: Makes ObjectQL dependency visible in plugin list -5. **Configuration**: Custom host context can be passed to ObjectQL -6. **Backward Compatible**: Existing code continues to work - -## Migration Guide - -### For New Projects - -Use Pattern 1 (recommended): -```typescript -new ObjectStackKernel([ - new ObjectQLPlugin(), - // other plugins -]); -``` - -### For Existing Projects - -No changes required! But consider migrating: - -**Before:** -```typescript -const kernel = new ObjectStackKernel([appConfig, driver]); -``` - -**After:** -```typescript -const kernel = new ObjectStackKernel([ - new ObjectQLPlugin(), - appConfig, - driver -]); -``` - -### For Custom ObjectQL Projects - -Use Pattern 2: -```typescript -import { MyCustomObjectQL } from './my-objectql'; - -const customQL = new MyCustomObjectQL({ /* config */ }); -const kernel = new ObjectStackKernel([ - new ObjectQLPlugin(customQL), - // other plugins -]); -``` - -## Validation - -All validations passed: -- โœ… Structural validation (files exist, exports correct) -- โœ… Plugin detection logic (6 test cases) -- โœ… Example usage (3 examples validated) -- โœ… Backward compatibility - -## Future Enhancements - -Possible future improvements: -1. Add TypeScript strict mode compatibility -2. Add comprehensive test suite -3. Support multiple ObjectQL instances for multi-tenant scenarios -4. Add ObjectQL instance validation in plugin -5.
