Driver Interface + +All drivers must implement the `Driver` interface from `@objectql/types`: + +```typescript +import { Driver } from '@objectql/types'; + +export class MyCustomDriver implements Driver { + name = 'MyCustomDriver'; + + // Connection lifecycle + async connect() { + // Initialize connection + } + + async disconnect() { + // Close connection + } + + // Required CRUD methods + async find(objectName: string, query: any, options?: any): Promise { } + async findOne(objectName: string, id: string | number, query?: any, options?: any): Promise { } + async create(objectName: string, data: any, options?: any): Promise { } + async update(objectName: string, id: string | number, data: any, options?: any): Promise { } + async delete(objectName: string, id: string | number, options?: any): Promise { } + async count(objectName: string, filters: any, options?: any): Promise { } + + // Optional methods + async distinct?(objectName: string, field: string, filters?: any, options?: any): Promise { } + async createMany?(objectName: string, data: any[], options?: any): Promise { } + async updateMany?(objectName: string, filters: any, data: any, options?: any): Promise { } + async deleteMany?(objectName: string, filters: any, options?: any): Promise { } +} +``` + +## 2. Implementing CRUD Operations + +### Find (Query) + +The `find` method receives a query object with filters, sorting, and pagination: + +```typescript +async find(objectName: string, query: any = {}, options?: any): Promise { + // 1. Get data for the object + // 2. Apply filters (where conditions) + // 3. Apply sorting + // 4. Apply pagination (skip/limit) + // 5. Apply field projection + return results; +} +``` + +**Query Structure:** + +```typescript +{ + filters: [['field', 'operator', value], 'and', ['field2', 'operator', value2]], + sort: [['field', 'asc'], ['field2', 'desc']], + skip: 0, + limit: 10, + fields: ['id', 'name', 'status'] +} +``` + +### Create (Insert) + +```typescript +async create(objectName: string, data: any, options?: any): Promise { + // 1. Generate ID if not provided + const id = data.id || this.generateId(objectName); + + // 2. Add timestamps + const record = { + ...data, + id, + created_at: new Date().toISOString(), + updated_at: new Date().toISOString() + }; + + // 3. Store the record + // 4. Return the created record + return record; +} +``` + +### Update + +```typescript +async update(objectName: string, id: string | number, data: any, options?: any): Promise { + // 1. Find existing record + // 2. Merge changes (preserve id and created_at) + // 3. Update updated_at timestamp + // 4. Save and return updated record +} +``` + +### Delete + +```typescript +async delete(objectName: string, id: string | number, options?: any): Promise { + // 1. Remove record by ID + // 2. Return success/failure +} +``` + +## 3. Filter Support + +ObjectQL uses a unified filter format: + +```typescript +// Simple condition +[['status', '=', 'active']] + +// Multiple conditions with AND +[['status', '=', 'active'], 'and', ['priority', '=', 'high']] + +// Multiple conditions with OR +[['status', '=', 'active'], 'or', ['status', '=', 'planning']] + +// Comparison operators +[['budget', '>', 50000]] +[['budget', '<=', 100000]] + +// String operators +[['name', 'contains', 'project']] +[['name', 'startswith', 'Web']] + +// Array operators +[['status', 'in', ['active', 'planning']]] +``` + +**Supported Operators:** + +- `=`, `!=` - Equality +- `>`, `>=`, `<`, `<=` - Comparison +- `in`, `not in` - Array membership +- `contains`, `like` - String search +- `startswith`, `endswith` - String prefix/suffix + +## 4. Type Handling + +Use types from `@objectql/types`: + +```typescript +import { + Driver, // Main driver interface + UnifiedQuery, // Query structure + ObjectQLError // Standardized errors +} from '@objectql/types'; +``` + +## 5. Error Handling + +Always use `ObjectQLError` for consistency: + +```typescript +import { ObjectQLError } from '@objectql/types'; + +throw new ObjectQLError({ + code: 'NOT_FOUND', + message: `Record with id '${id}' not found`, + details: { objectName, id } +}); +``` + +**Standard Error Codes:** + +- `INVALID_REQUEST` - Invalid parameters +- `NOT_FOUND` - Record not found +- `CONFLICT` - Duplicate record +- `VALIDATION_ERROR` - Data validation failed +- `UNAUTHORIZED` - Authentication required +- `FORBIDDEN` - Permission denied +- `INTERNAL_ERROR` - Internal error + +## 6. Registering the Driver + +### Method 1: Direct Usage + +```typescript +import { ObjectQL } from '@objectql/core'; +import { InMemoryDriver } from './memory-driver'; + +const driver = new InMemoryDriver(); + +const app = new ObjectQL({ + datasources: { + default: driver + } +}); +``` + +### Method 2: As a Plugin + +```typescript +// index.ts +import { InMemoryDriver } from './memory-driver'; + +export default { + name: 'plugin-driver-memory', + version: '1.0.0', + drivers: [new InMemoryDriver()] +}; +``` + +```typescript +// app.ts +import { ObjectQL } from '@objectql/core'; +import MyDriverPlugin from './my-driver'; + +const app = new ObjectQL({ + plugins: [MyDriverPlugin] +}); +``` + +## 7. Example: In-Memory Driver + +See the implementation in `src/memory-driver.ts`: + +**Features:** + +βœ… Full CRUD operations +βœ… Query filters, sorting, pagination +βœ… Field projection +βœ… Aggregate operations (count, distinct) +βœ… Timestamps (created_at, updated_at) +βœ… ID generation +βœ… Error handling with ObjectQLError + +**Storage Format:** + +```typescript +Map> + +Example: +{ + "projects": { + "proj-1": { id: "proj-1", name: "Website", status: "active" }, + "proj-2": { id: "proj-2", name: "Mobile App", status: "planning" } + } +} +``` + +## 8.

Advanced Topics + +### Transactions (Optional) + +```typescript +async beginTransaction?(): Promise; +async commitTransaction?(trx: any): Promise; +async rollbackTransaction?(trx: any): Promise; +``` + +### Schema Introspection (Optional) + +```typescript +async introspectSchema?(): Promise; +``` + +Allows connecting to existing databases without defining metadata. + +### Bulk Operations (Optional) + +```typescript +async createMany?(objectName: string, data: any[], options?: any): Promise; +async updateMany?(objectName: string, filters: any, data: any, options?: any): Promise; +async deleteMany?(objectName: string, filters: any, options?: any): Promise; +``` + +## 10. Testing Your Driver + +```typescript +import { InMemoryDriver } from './memory-driver'; + +async function testDriver() { + const driver = new InMemoryDriver(); + + // Test create + const record = await driver.create('users', { name: 'Alice', role: 'admin' }); + console.assert(record.id !== undefined, 'ID should be generated'); + + // Test find + const results = await driver.find('users', {}); + console.assert(results.length === 1, 'Should have 1 record'); + + // Test update + await driver.update('users', record.id, { role: 'superadmin' }); + const updated = await driver.findOne('users', record.id); + console.assert(updated.role === 'superadmin', 'Role should be updated'); + + // Test delete + await driver.delete('users', record.id); + const remaining = await driver.find('users', {}); + console.assert(remaining.length === 0, 'Should have 0 records'); + + console.log('βœ… All tests passed!'); +} +``` + +## 11. Best Practices + +1. **Use TypeScript** - Type safety prevents runtime errors +2. **Handle Errors Gracefully** - Use `ObjectQLError` for consistency +3. **Add Timestamps** - Auto-add `created_at` and `updated_at` +4. **Generate IDs** - If not provided by the data source +5. **Support Pagination** - Always respect `skip` and `limit` +6. **Test Thoroughly** - Test all CRUD operations and edge cases +7. **Document Your Driver** - Explain configuration options and limitations + +## 12. Next Steps + +- **Add Transaction Support** - Implement atomic operations +- **Add Caching** - Cache frequently accessed data +- **Add Schema Validation** - Validate data before storage +- **Add Connection Pooling** - For database drivers +- **Add Performance Monitoring** - Track query execution times + +## 13.

Type Handling - -Use types from `@objectql/types`: - -```typescript -import { - Driver, // Main driver interface - UnifiedQuery, // Query structure - ObjectQLError // Standardized errors -} from '@objectql/types'; -``` - -## 5. Error Handling - -Always use `ObjectQLError` for consistency: - -```typescript -import { ObjectQLError } from '@objectql/types'; - -throw new ObjectQLError({ - code: 'NOT_FOUND', - message: `Record with id '${id}' not found`, - details: { objectName, id } -}); -``` - -**Standard Error Codes:** - -- `INVALID_REQUEST` - Invalid parameters -- `NOT_FOUND` - Record not found -- `CONFLICT` - Duplicate record -- `VALIDATION_ERROR` - Data validation failed -- `UNAUTHORIZED` - Authentication required -- `FORBIDDEN` - Permission denied -- `INTERNAL_ERROR` - Internal error - -## 6. Registering the Driver - -### Method 1: Direct Usage - -```typescript -import { ObjectQL } from '@objectql/core'; -import { InMemoryDriver } from './memory-driver'; - -const driver = new InMemoryDriver(); - -const app = new ObjectQL({ - datasources: { - default: driver - } -}); -``` - -### Method 2: As a Plugin - -```typescript -// index.ts -import { InMemoryDriver } from './memory-driver'; - -export default { - name: 'plugin-driver-memory', - version: '1.0.0', - drivers: [new InMemoryDriver()] -}; -``` - -```typescript -// app.ts -import { ObjectQL } from '@objectql/core'; -import MyDriverPlugin from './my-driver'; - -const app = new ObjectQL({ - plugins: [MyDriverPlugin] -}); -``` - -## 7.

Testing Your Driver - -```typescript -import { InMemoryDriver } from './memory-driver'; - -async function testDriver() { - const driver = new InMemoryDriver(); - - // Test create - const record = await driver.create('users', { name: 'Alice', role: 'admin' }); - console.assert(record.id !== undefined, 'ID should be generated'); - - // Test find - const results = await driver.find('users', {}); - console.assert(results.length === 1, 'Should have 1 record'); - - // Test update - await driver.update('users', record.id, { role: 'superadmin' }); - const updated = await driver.findOne('users', record.id); - console.assert(updated.role === 'superadmin', 'Role should be updated'); - - // Test delete - await driver.delete('users', record.id); - const remaining = await driver.find('users', {}); - console.assert(remaining.length === 0, 'Should have 0 records'); - - console.log('βœ… All tests passed!'); -} -``` - -## 11. Best Practices - -1. **Use TypeScript** - Type safety prevents runtime errors -2. **Handle Errors Gracefully** - Use `ObjectQLError` for consistency -3. **Add Timestamps** - Auto-add `created_at` and `updated_at` -4. **Generate IDs** - If not provided by the data source -5. **Support Pagination** - Always respect `skip` and `limit` -6. **Test Thoroughly** - Test all CRUD operations and edge cases -7. **Document Your Driver** - Explain configuration options and limitations - -## 12. Next Steps - -- **Add Transaction Support** - Implement atomic operations -- **Add Caching** - Cache frequently accessed data -- **Add Schema Validation** - Validate data before storage -- **Add Connection Pooling** - For database drivers -- **Add Performance Monitoring** - Track query execution times - -## 13.
