Quest 4 Completion Summary: Maze of API Integrations 🌐

Overview​

Successfully navigated the Maze of API Integrations by implementing comprehensive RESTful API endpoints that expose our artifact system service layer through clean, well-documented routes following established Next.js patterns.

🏗️ API Architecture Implementation​

API Route Structure​

Built following the established Next.js API Routes pattern:

  • Location: packages/client/pages/api/artifacts/
  • Middleware: Leveraging baseApi() and asyncHandler patterns
  • Authentication: Integrated with existing auth middleware
  • Error Handling: Consistent error responses using established error classes
  • Validation: Zod schema validation for all request/response data

Core API Endpoints​

1. Main Artifacts API (/api/artifacts)​

File: packages/client/pages/api/artifacts/index.ts

GET /api/artifacts - List artifacts with filtering and pagination

  • Query parameters: limit, offset, sortBy, sortOrder, type, status, visibility, projectId, sessionId, tags, search
  • Returns paginated list with metadata
  • Supports text search across titles and descriptions

POST /api/artifacts - Create new artifact

  • Validates comprehensive artifact data using Zod schema
  • Supports all artifact types: mermaid, rechart, python, react, html, svg, code, quest, file, questmaster
  • Handles permissions, visibility, versioning, and metadata

2. Individual Artifact Management (/api/artifacts/[id])​

File: packages/client/pages/api/artifacts/[id]/index.ts

GET /api/artifacts/[id] - Retrieve specific artifact

  • Includes content by default
  • Optional version history inclusion
  • Permission-based access control

PUT /api/artifacts/[id] - Update artifact

  • Partial updates supported
  • Automatic versioning when content changes
  • Permission validation

DELETE /api/artifacts/[id] - Soft delete artifact

  • Maintains audit trail
  • Permission-based deletion

3. Search API (/api/artifacts/search)​

File: packages/client/pages/api/artifacts/search.ts

GET /api/artifacts/search - Advanced artifact search

  • Full-text search across artifact content
  • Filtering by type, visibility, project, tags
  • Pagination and sorting support

4. QuestMaster API (/api/artifacts/questmaster)​

File: packages/client/pages/api/artifacts/questmaster/index.ts

GET /api/artifacts/questmaster - List quest artifacts

  • Quest-specific filtering: questType, complexity, status
  • Duration-based sorting
  • Dependency tracking

POST /api/artifacts/questmaster - Create quest artifacts

  • Quest-specific schema with complexity levels
  • Resource linking (documentation, tutorials, examples)
  • Prerequisite and dependency management

5. Utility APIs​

GET /api/artifacts/types - Available artifact types File: packages/client/pages/api/artifacts/types.ts

  • Returns all supported artifact types with metadata
  • Categorizes types by purpose (visualization, interactive, web, etc.)
  • Helps frontend build appropriate UI components

🔧 Repository Implementation​

Database Repository Classes​

Enhanced all artifact models with production-ready repository implementations:

ArtifactRepository​

File: b4m-core/packages/core/database/src/models/ArtifactModel.ts

  • Methods: findByType, findByUser, findByProject, findBySession, findActive, findByStatus, findByVisibility
  • Search: searchByText with MongoDB text indexes
  • Access Control: findByUserWithAccess with permission checking
  • Soft Delete: softDelete, restore, findDeleted
  • Deduplication: findDuplicatesByHash

ArtifactContentRepository​

File: b4m-core/packages/core/database/src/models/ArtifactContentModel.ts

  • Methods: findByArtifactId, findByArtifactAndVersion, findByContentHash
  • Versioning: findLatestByArtifact, getContentVersions
  • Performance: Separated content storage for optimal querying

ArtifactVersionRepository​

File: b4m-core/packages/core/database/src/models/ArtifactVersionModel.ts

  • Methods: findByArtifactId, findActiveVersion, findByVersion, findByCreator
  • History: getVersionHistory with full lineage tracking
  • Management: setActiveVersion with atomic updates

🛡️ API Security & Validation​

Authentication & Authorization​

  • JWT Authentication: Required for all endpoints
  • User Context: Automatic user ID extraction from tokens
  • Permission Checks: Granular access control per artifact
  • Resource Ownership: User-based resource isolation

Request Validation​

  • Zod Schemas: Comprehensive validation for all inputs
  • Type Safety: Full TypeScript integration
  • Error Messages: Clear validation error responses
  • Input Sanitization: Preventing malicious data injection

Data Validation Schemas​

// Create Artifact Schema
- type: Enum validation (10 supported types)
- title: String (1-255 chars)
- content: Required string
- visibility: Enum (private/project/organization/public)
- permissions: Granular access arrays
- metadata: Flexible object storage

// List/Search Schemas
- Pagination: limit (1-100), offset (≥0)
- Sorting: Enum-based sort fields and orders
- Filtering: Type-safe filter parameters

📊 API Response Patterns​

Standard Response Format​

{
  "data": {}, // Main response data
  "pagination": { // For list endpoints
    "limit": 20,
    "offset": 0,
    "total": 150,
    "hasMore": true
  },
  "meta": {} // Additional metadata
}

Error Responses​

{
  "error": "Descriptive error message",
  "code": "ERROR_CODE",
  "details": {} // Additional error context
}

🔌 Integration Points​

Service Layer Integration​

  • Clean Architecture: APIs delegate to service layer
  • Dependency Injection: Repository pattern with injected dependencies
  • Business Logic Separation: APIs focus on HTTP concerns only
  • Error Mapping: Service errors mapped to appropriate HTTP status codes

Database Integration​

  • Repository Pattern: Consistent data access layer
  • Connection Management: Handled by existing middleware
  • Transaction Support: Available for complex operations
  • Performance: Optimized queries with proper indexing

Frontend Integration Ready​

  • TypeScript Types: Shared types between frontend/backend
  • Hook Compatibility: Designed for React hooks integration
  • Real-time Support: Foundation for WebSocket updates
  • Caching: ETags and conditional requests support
