|
||||
|
||||
### Features Implemented
|
||||
## Testing Notes
|
||||
|
||||
#### LocalSQLAdapter
|
||||
The UI components use IPC handlers registered in main.js. To test:
|
||||
|
||||
- ✅ Implements same API as existing `CloudStore` class
|
||||
- ✅ Uses `better-sqlite3` for local SQLite storage
|
||||
- ✅ WAL mode for better concurrent access
|
||||
- ✅ Event emission (create, save, delete, fetch)
|
||||
- ✅ Auto-create tables on first access
|
||||
- ✅ Auto-add columns for new fields
|
||||
1. Run `npm run dev`
|
||||
2. Open Backend Services panel
|
||||
3. Create a local backend (name it)
|
||||
4. Start/Stop the backend
|
||||
5. Check the displayed endpoint when running
|
||||
|
||||
#### QueryBuilder
|
||||
## Architecture Summary
|
||||
|
||||
- ✅ Translates Parse-style queries to SQL
|
||||
- ✅ All operators: `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`
|
||||
- ✅ Collection operators: `$in`, `$nin`
|
||||
- ✅ Existence: `$exists`
|
||||
- ✅ Logical: `$and`, `$or`
|
||||
- ✅ Relation support: `$relatedTo`
|
||||
- ✅ Parse types: Date, Pointer
|
||||
- ✅ SQL injection prevention
|
||||
- ✅ Value serialization/deserialization
|
||||
|
||||
#### SchemaManager
|
||||
|
||||
- ✅ Create tables from Noodl schemas
|
||||
- ✅ Add columns dynamically
|
||||
- ✅ Junction tables for relations
|
||||
- ✅ Export to PostgreSQL SQL
|
||||
- ✅ Export to Supabase SQL (with RLS policies)
|
||||
- ✅ JSON schema export/import
|
||||
- ✅ Schema tracking in `_Schema` table
|
||||
|
||||
### CloudStore Interface Methods
|
||||
|
||||
| Method | Status | Notes |
|
||||
| ------------------ | ------ | ----------------------- |
|
||||
| `query()` | ✅ | Full Parse query syntax |
|
||||
| `fetch()` | ✅ | Single record by ID |
|
||||
| `create()` | ✅ | With auto ID generation |
|
||||
| `save()` | ✅ | Update existing |
|
||||
| `delete()` | ✅ | By objectId |
|
||||
| `count()` | ✅ | With where filter |
|
||||
| `aggregate()` | ✅ | sum, avg, max, min |
|
||||
| `distinct()` | ✅ | Unique values |
|
||||
| `increment()` | ✅ | Atomic increment |
|
||||
| `addRelation()` | ✅ | Via junction tables |
|
||||
| `removeRelation()` | ✅ | Via junction tables |
|
||||
| `on()` / `off()` | ✅ | Event subscription |
|
||||
|
||||

|
||||
|
||||
## Testing Status
|
||||
|
||||
### Unit Tests
|
||||
|
||||
- ✅ QueryBuilder tests written (56 test cases)
|
||||
- ⚠️ Runtime package has dependency issues (`terminal-link` missing)
|
||||
- Tests need `npm install` at repo root to run
|
||||
|
||||
### Manual Testing
|
||||
|
||||
- 🔲 Pending - requires `better-sqlite3` installation
|
||||
|
||||
---
|
||||
|
||||
## What's Next
|
||||
|
||||
### Remaining for TASK-007A
|
||||
|
||||
1. Install missing test dependencies
|
||||
2. Run and verify all tests pass
|
||||
3. Manual integration test with real database
|
||||
|
||||
### Next Steps (TASK-007B: Backend Server)
|
||||
|
||||
- Express server implementation
|
||||
- REST endpoints matching CloudStore API
|
||||
- WebSocket for realtime updates
|
||||
- IPC handlers for Electron main process
|
||||

## Usage Example
|
||||
|
||||
```javascript
|
||||
const { LocalSQLAdapter } = require('@noodl/runtime/src/api/adapters');
|
||||
|
||||
// Create adapter
|
||||
const adapter = new LocalSQLAdapter('/path/to/database.db');
|
||||
await adapter.connect();
|
||||
|
||||
// Create a record
|
||||
adapter.create({
|
||||
collection: 'todos',
|
||||
data: { title: 'Learn Noodl', completed: false },
|
||||
success: (record) => console.log('Created:', record),
|
||||
error: (err) => console.error(err)
|
||||
});
|
||||
|
||||
// Query records
|
||||
adapter.query({
|
||||
collection: 'todos',
|
||||
where: { completed: { $eq: false } },
|
||||
sort: '-createdAt',
|
||||
limit: 10,
|
||||
success: (results) => console.log('Todos:', results),
|
||||
error: (err) => console.error(err)
|
||||
});
|
||||
|
||||
// Export schema to PostgreSQL
|
||||
const pgSQL = adapter.getSchemaManager().generatePostgresSQL();
|
||||
console.log(pgSQL);
|
||||
```
|
||||

|
||||
|
||||
## Notes
|
||||
|
||||
- The adapter matches the callback-based API of CloudStore for compatibility
|
||||
- `better-sqlite3` is required but not added to package.json yet
|
||||
- Will be added when integrating with Backend Server (TASK-007B)
|
||||
- ESLint warnings about `require()` are expected (CommonJS package)
