Work Summary: OpenAPI Client Migration - Session 2

Date: 2026-01-19
Session Focus: Continue migration of web frontend to use OpenAPI-generated TypeScript client

---

Overview

Continued the systematic migration of the Attune web frontend from manual axios calls to the auto-generated OpenAPI TypeScript client. This session focused on migrating core React Query hooks and updating pages to use correct schema field names and types.

---

Accomplishments

1. ✅ Migrated Core React Query Hooks (4 hooks)

useActions.ts - Migrated to ActionsService

• Replaced manual axios calls with ActionsService.listActions(), getAction(), createAction(), updateAction(), deleteAction()
• Updated parameter names to match API spec (pageSize, packRef)
• Changed from ID-based to reference-based lookups (using ref instead of id)
• Fixed return values to use paginated response structure
• Removed non-existent endpoints: useToggleActionEnabled(), useExecuteAction()
• Uses listActionsByPack() for pack-filtered queries

useExecutions.ts - Migrated to ExecutionsService

• Replaced manual axios calls with ExecutionsService.listExecutions(), getExecution()
• Updated parameter names (perPage instead of pageSize, actionRef)
• Added proper ExecutionStatus enum type support
• Fixed return values to use paginated response structure

usePacks.ts - Migrated to PacksService

• Replaced manual axios calls with PacksService.listPacks(), getPack(), createPack(), updatePack(), deletePack()
• Updated parameter names (pageSize instead of page_size)
• Changed from string | number to string for ref parameter
• Uses generated CreatePackRequest and UpdatePackRequest types
• Fixed return values to use paginated response structure

useRules.ts - Migrated to RulesService

• Replaced manual axios calls with RulesService methods
• Implemented smart query routing based on filter parameters:
  • Uses listRulesByPack() when packRef provided
  • Uses listRulesByAction() when actionRef provided
  • Uses listRulesByTrigger() when triggerRef provided
  • Falls back to listRules() for unfiltered queries
• Updated parameter names (pageSize, packRef, actionRef, triggerRef)
• Removed non-existent endpoints: useEnableRule(), useDisableRule()
• Uses generated CreateRuleRequest and UpdateRuleRequest types

2. ✅ Updated Pages and Components (5 files)

ActionDetailPage.tsx

• Updated route parameter from :id to :ref
• Fixed all field name references:
  • pack_name → pack_ref
  • name → ref (unique ID) and label (display name)
  • entry_point → entrypoint
  • parameters → param_schema
  • metadata → out_schema
• Removed non-existent fields: enabled, runner_type, metadata
• Removed execute action functionality (not in backend API)
• Fixed data access for response wrapper: action.data.field
• Fixed pagination access: executionsData.data for items, executionsData.pagination.total_items
• Updated ExecutionStatus comparisons to use enum values

ActionsPage.tsx

• Updated table columns to show correct fields
• Changed from ID-based to reference-based links
• Removed enabled status column (field doesn't exist in backend)
• Shows: Reference (ref), Label, Pack (pack_ref), Description
• Fixed paginated response data access

DashboardPage.tsx

• Updated all parameter names to camelCase (pageSize instead of page_size)
• Fixed ExecutionStatus enum usage throughout:
  • String literals → Enum values (e.g., "running" → ExecutionStatus.RUNNING)
  • Updated all status comparisons and switch statements
• Fixed pagination metadata access: total_items instead of total
• Fixed paginated response data access: data instead of items
• Removed references to removed fields:
  • elapsed_ms (no longer in ExecutionSummary)
  • pack_name, action_name (use action_ref instead)
• Updated status display logic for all enum values:
  • REQUESTED, SCHEDULING, SCHEDULED, RUNNING, COMPLETED, FAILED, CANCELING, CANCELLED, TIMEOUT, ABANDONED

RuleForm.tsx

• Fixed parameter name: page_size → pageSize
• Fixed paginated response data access: data instead of items
• Added trigger_params field to satisfy UpdateRuleRequest type
• Fixed response data access: newRule.data.ref instead of newRule.id
• Updated mutation calls to use ref instead of id

App.tsx

• Updated action route from /actions/:id to /actions/:ref

3. ✅ Key Schema Changes Applied

Field Name Mapping:

• name → ref (unique identifier) + label (display name)
• pack_id → pack (just the ID number)
• pack_name → pack_ref (pack reference string)
• entry_point → entrypoint (camelCase)
• parameters → param_schema (schema definition)
• action_parameters → action_params (shortened)
• criteria → conditions (renamed)

Parameter Name Standardization:

• page_size → pageSize (camelCase)
• pack_ref → packRef (camelCase)
• action_id → actionRef (reference instead of ID)
• trigger_id → triggerRef (reference instead of ID)

Pagination Structure:

• Old: items array, total number
• New: data array, pagination.total_items number
• Pagination metadata includes: page, page_size, total_items, total_pages

ExecutionStatus Enum:

• Old: Lowercase string literals ("running", "succeeded", "failed")
• New: PascalCase enum values (ExecutionStatus.RUNNING, ExecutionStatus.COMPLETED, ExecutionStatus.FAILED)

Removed Fields (Don't exist in backend):

• enabled on actions and rules
• runner_type on actions
• metadata on actions (replaced with out_schema)
• elapsed_ms on executions
• pack_name, action_name on executions (use action_ref)
• start_time, end_time on executions
• error_message on executions (check result field)
• log_path on executions

4. ✅ Documentation Updates

Updated web/API-MIGRATION-STATUS.md:

• Progress tracking: 9/16 files fixed (56% complete)
• Added detailed migration notes for each completed file
• Added "Important Schema Notes" section covering:
  • Paginated response structure
  • ExecutionStatus enum values
  • Common mistakes and how to avoid them
• Updated completion status for hooks and pages
• Documented all field name mappings

Updated work-summary/TODO.md:

• Marked Phase 2 (Hooks Migration) as complete
• Updated Phase 3 (Schema Alignment) progress to 56%
• Listed all completed files and remaining work
• Updated TypeScript error count tracking

Technical Details

Migration Pattern Established

1. Hook Migration:

   // Before
   const response = await apiClient.get('/api/v1/actions', { params: { page_size: 50 } });
   return response.data.data;
   
   // After
   const response = await ActionsService.listActions({ pageSize: 50 });
   return response; // Already unwrapped
   

2. Pagination Access:

   // Before
   const items = data?.items || [];
   const total = data?.total || 0;
   
   // After
   const items = data?.data || [];
   const total = data?.pagination?.total_items || 0;
   

3. Enum Usage:

   // Before
   if (status === "running") { ... }
   
   // After
   if (status === ExecutionStatus.RUNNING) { ... }
   

Common Pitfalls Identified and Documented

1. Using items and total instead of data and total_items
2. Using string literals instead of enum values for ExecutionStatus
3. Trying to access removed fields like enabled, runner_type, metadata
4. Using id instead of ref for resource lookups
5. Using snake_case instead of camelCase for parameters

Testing Status

Manual Testing

• ✅ Hook migration compiles without errors
• ✅ Type definitions correctly imported
• ⏳ Runtime testing pending (requires backend running)
• ⏳ End-to-end workflow testing pending

Type Safety

• ✅ All migrated hooks have compile-time type checking
• ✅ All parameter types validated at compile time
• ✅ All response types validated at compile time
• ✅ Enum values enforced by TypeScript

---

Lessons Learned

1. Pagination Structure: Backend uses data array with pagination metadata object, not items and total
2. Enum Values: ExecutionStatus uses PascalCase enum values, not lowercase strings
3. Reference-Based APIs: Backend prefers ref strings over numeric id values for most resources
4. Smart Query Routing: Some services provide specialized list methods (listByPack, listByAction) that must be used instead of the generic list method with filters
5. Field Removal: Several fields (enabled, runner_type, metadata, elapsed_ms) don't exist in the backend schema and must be removed from frontend
