Storage Operations

The client implements file storage operations though they're not explicitly defined as a separate namespace in DEFAULT_DISPATCHER_ROUTES:

Operation	Client Method	Status
Get Presigned URL	storage.getPresignedUrl()	✅
Upload File	storage.upload()	✅
Complete Upload	storage.completeUpload()	✅
Get Download URL	storage.getDownloadUrl()	✅

Note: Storage operations use the /api/v1/storage prefix though not in DEFAULT_DISPATCHER_ROUTES. This is expected as storage can be plugin-provided.

---

Hub Operations

The client implements hub connectivity operations:

Operation	Client Method	Status
Connect to Hub	hub.connect()	✅

---

Architecture & Implementation Notes

Request/Response Envelope

The client correctly implements the standard response envelope pattern:

• All server responses wrapped in { success: boolean, data: T, meta?: any }
• unwrapResponse() helper extracts inner data payload
• Error responses use ApiErrorSchema with StandardErrorCode enum

Authentication

• JWT token passed via Authorization: Bearer <token> header
• Token configurable via ClientConfig.token
• auth.login() returns session with token for subsequent requests

HTTP Methods

Client uses correct HTTP verbs per REST conventions:

• GET for read operations (find, get, list)
• POST for create and complex queries (create, query, batch operations)
• PATCH for updates (update)
• PUT for save/upsert (saveItem)
• DELETE for deletions (delete)

Query Strategies

The client supports three query approaches:

1. Simplified (data.find()) - Query params for basic filters
2. AST (data.query()) - Full ObjectQL AST via POST body
3. Direct (data.get()) - Retrieve by ID

Route Resolution

• getRoute(namespace) helper resolves API prefix from discovery info
• Fallback to /api/v1/{namespace} if discovery not available
• Supports custom base URLs via ClientConfig.baseUrl

---

Testing Requirements

To verify client-server integration, tests should cover:

1. Connection & Discovery

   • ✓ Standard discovery via .well-known/objectstack
   • ✓ Fallback discovery via /api/v1
   • ✓ Capability detection
   • ✓ Route mapping

2. Authentication Flow

   • ✓ Login (email/password, magic link, social)
   • ✓ Token management
   • ✓ Session refresh
   • ✓ Logout

3. CRUD Operations

   • ✓ Create single/many records
   • ✓ Read with filters, pagination, sorting
   • ✓ Update single/many records
   • ✓ Delete single/many records
   • ✓ Batch mixed operations

4. Advanced Features

   • ✓ Complex queries (ObjectQL AST)
   • ✓ Metadata caching (ETag)
   • ✓ Workflow transitions
   • ✓ Permission checks
   • ✓ Realtime subscriptions
   • ✓ File uploads/downloads
   • ✓ AI operations

5. Error Handling

   • ✓ Network errors
   • ✓ 4xx client errors
   • ✓ 5xx server errors
   • ✓ Standard error codes
   • ✓ Validation errors

See CLIENT_SERVER_INTEGRATION_TESTS.md for detailed test specifications.
