## SQLite Rebuild System
### Architecture Overview
The system uses a comprehensive SQLite-based approach modeled after n8n-mcp:
1. **Database Adapter Layer**: Abstracts SQLite operations with better-sqlite3/sql.js fallback
2. **Repository Pattern**: Motion repository provides clean data access layer
3. **Service Layer**: Documentation service handles fetching, parsing, and storage
4. **Rebuild Scripts**: Automated scripts for downloading all Motion.dev documentation
5. **FTS5 Search**: Full-text search with graceful LIKE fallback
### Key Components
#### Database Adapter (`src/database/database-adapter.ts`)
```typescript
// Provides unified interface for SQLite operations
export interface DatabaseAdapter {
prepare(sql: string): DatabaseStatement;
exec(sql: string): void;
checkFTS5Support(): boolean;
close(): void;
}
```
#### Motion Repository (`src/database/motion-repository.ts`)
```typescript
// Handles all CRUD operations for Motion.dev data
export class MotionRepository {
saveDoc(doc: MotionDoc): void;
searchDocs(query: string, options?: SearchOptions): MotionDoc[];
getComponent(name: string, framework: Framework): MotionComponent | null;
searchExamples(query: string, options?: SearchOptions): MotionExample[];
getStatistics(): DatabaseStatistics;
}
```
#### Rebuild Process (`src/scripts/rebuild-docs.ts`)
```bash
# Run the complete rebuild process
npm run rebuild
# Custom database path
MOTION_DB_PATH=./custom/docs.db npm run rebuild
# Check database statistics after rebuild
npm run stats
```
### Database Schema
- **motion_docs**: Core documentation pages with full-text content
- **motion_components**: Component and function definitions
- **motion_examples**: Code examples with difficulty levels
- **FTS5 Tables**: Full-text search indexes when supported
- **Triggers**: Automatic FTS index maintenance
### Performance Features
- **Connection Pooling**: Efficient database connections
- **Prepared Statements**: SQL injection protection and performance
- **Batch Operations**: Bulk inserts during rebuild process
- **Indexed Queries**: Optimized for common access patterns
- **Error Recovery**: Graceful handling of network failures
### Usage Examples
```typescript
// Initialize the system
const db = await createDatabaseAdapter('./docs/motion-docs.db');
const repository = new MotionRepository(db);
// Search documentation
const results = repository.searchDocs('spring animation', {
framework: 'react',
limit: 10
});
// Get component API
const component = repository.getComponent('motion.div', 'react');
// Database statistics
const stats = repository.getStatistics();
// Returns: { totalDocs: 150, totalComponents: 45, totalExamples: 89, hasFTS5: true }
```
