Error (Default) + +Throws an error when a route conflict is detected. + +```typescript +kernel.use(createApiRegistryPlugin({ conflictResolution: 'error' })); +``` + +**Best for:** Production environments where conflicts should be caught early. + +### 2. Priority + +Uses the `priority` field on endpoints to resolve conflicts. Higher priority wins. + +```typescript +kernel.use(createApiRegistryPlugin({ conflictResolution: 'priority' })); + +// In your plugin +registry.registerApi({ + endpoints: [ + { + path: '/api/data/:object', + priority: 900, // Core API (high priority) + }, + ], +}); +``` + +**Priority Ranges:** +- **900-1000**: Core system endpoints +- **500-900**: Custom/override endpoints +- **100-500**: Plugin endpoints +- **0-100**: Fallback routes + +### 3. First-Wins + +First registered endpoint wins. Subsequent registrations are ignored. + +```typescript +kernel.use(createApiRegistryPlugin({ conflictResolution: 'first-wins' })); +``` + +**Best for:** Stable, predictable routing where load order matters. + +### 4. Last-Wins + +Last registered endpoint wins. Previous registrations are overwritten. + +```typescript +kernel.use(createApiRegistryPlugin({ conflictResolution: 'last-wins' })); +``` + +**Best for:** Development/testing where you want to override defaults. + +## RBAC Integration + +Endpoints can specify required permissions that are automatically validated at the gateway level: + +```typescript +{ + id: 'delete_customer', + method: 'DELETE', + path: '/api/v1/customers/:id', + requiredPermissions: [ + 'customer.delete', + 'api_enabled', + ], + responses: [], +} +``` + +**Permission Format:** +- **Object Permissions:** `.` (e.g., `customer.read`, `order.delete`) +- **System Permissions:** `` (e.g., `manage_users`, `api_enabled`) + +## Dynamic Schema Linking + +Reference ObjectQL objects instead of static schemas: + +```typescript +{ + statusCode: 200, + description: 'Customer retrieved', + schema: { + $ref: { + objectId: 'customer', // ObjectQL object name + excludeFields: ['password_hash'], // Exclude sensitive fields + includeFields: ['id', 'name'], // Or whitelist specific fields + includeRelated: ['account'], // Include related objects + }, + }, +} +``` + +**Benefits:** +- API documentation auto-updates when object schemas change +- No schema duplication between API and data model +- Consistent type definitions across API and database + +## Protocol-Specific Configuration + +Support custom protocols with `protocolConfig`: + +### WebSocket + +```typescript +{ + id: 'customer_updates', + path: '/ws/customers', + protocolConfig: { + subProtocol: 'websocket', + eventName: 'customer.updated', +

06/10] Initial plan From 400b6245b11b6714dda5cea70d18826fc9d6e7c0 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Mon, 2 Feb 2026 07:55:04 +0000 Subject: [PATCH 07/10] feat: Add performance optimizations and safety guards to API Registry - Add auxiliary indices (apisByType, apisByTag, apisByStatus) for O(1) lookups - Optimize findApis() to use indices instead of full array filtering - Add safety guard to clear() method (requires force flag in production) - Add comprehensive documentation about route conflict detection limitations - Clarify ObjectQL schema reference resolution responsibility - Add 20+ new tests for performance optimizations and safety guards - Maintain full backward compatibility All 244 tests passing.
