## Technical Design: API Resource Standard
### Overview
This design establishes Laravel API Resources as the standard for all API responses, ensuring consistent `"data"` wrapper across all endpoints.
---
### Directory Structure
```
backend/app/Http/Resources/
├── BaseResource.php # Abstract base with common utilities
├── UserResource.php
├── RoleResource.php
├── TeamMemberResource.php
├── ProjectStatusResource.php
├── ProjectTypeResource.php
├── ProjectResource.php
├── HolidayResource.php
├── PtoResource.php
├── CapacityResource.php
├── TeamCapacityResource.php
└── RevenueResource.php
```
---
### Base Resource Design
```php
<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
abstract class BaseResource extends JsonResource
{
/**
* Standard date format for all API responses
*/
protected function formatDate($date): ?string
{
return $date?->toIso8601String();
}
/**
* Format decimal values consistently
*/
protected function formatDecimal($value, int $decimals = 2): ?float
{
return $value !== null ? round((float) $value, $decimals) : null;
}
}
```
---
### Resource Implementation Pattern
Each resource follows this pattern:
```php
<?php
namespace App\Http\Resources;
class TeamMemberResource extends BaseResource
{
public function toArray($request): array
{
return [
'id' => $this->id,
'name' => $this->name,
'role' => new RoleResource($this->whenLoaded('role')),
'hourly_rate' => $this->formatDecimal($this->hourly_rate),
'active' => (bool) $this->active,
'created_at' => $this->formatDate($this->created_at),
'updated_at' => $this->formatDate($this->updated_at),
];
}
}
```
---
### Controller Update Pattern
**BEFORE:**
```php
public function index(Request $request): JsonResponse
{
$members = $this->teamMemberService->getAll();
return response()->json($members);
}
```
**AFTER:**
```php
public function index(Request $request): JsonResponse
{
$members = $this->teamMemberService->getAll();
return response()->json(new TeamMemberResource($members));
// Or for collections:
// return response()->json(TeamMemberResource::collection($members));
}
```
---
### Relationship Loading Strategy
Use Laravel's `whenLoaded()` to conditionally include relationships:
```php
public function toArray($request): array
{
return [
'id' => $this->id,
'name' => $this->name,
// Only include role if it was eager loaded
'role' => new RoleResource($this->whenLoaded('role')),
// Only include team_member if it was eager loaded
'team_member' => new TeamMemberResource($this->whenLoaded('teamMember')),
];
}
```
**Controller Responsibility:**
```php
// Eager load relationships before passing to resource
$members = TeamMember::with('role')->get();
return response()->json(TeamMemberResource::collection($members));
```
---
### Frontend API Client Update
**Create helper function to unwrap responses:**
```typescript
// src/lib/api/client.ts
export async function unwrapResponse<T>(response: Response): Promise<T> {
const data = await response.json();
return data.data as T;
}
// Usage in API functions:
export async function getTeamMembers(): Promise<TeamMember[]> {
const response = await fetch('/api/team-members');
return unwrapResponse<TeamMember[]>(response);
}
```
**Update all API calls:**
```typescript
// BEFORE:
const members = await response.json();
// AFTER:
const members = await unwrapResponse<TeamMember[]>(response);
```
---
### Test Update Pattern
**Backend Feature Tests:**
```php
// BEFORE:
$response->assertJson(['name' => 'John Doe']);
// AFTER:
$response->assertJson(['data' => ['name' => 'John Doe']]);
// Or more explicitly:
$this->assertEquals('John Doe', $response->json('data.name'));
```
**Resource Unit Tests:**
```php
test('resource wraps single model in data key', function () {
$member = TeamMember::factory()->create();
$resource = new TeamMemberResource($member);
$this->assertArrayHasKey('data', $resource->resolve());
$this->assertEquals($member->id, $resource->resolve()['data']['id']);
});
test('collection wraps in data array', function () {
$members = TeamMember::factory(3)->create();
$collection = TeamMemberResource::collection($members);
$this->assertArrayHasKey('data', $collection->resolve());
$this->assertCount(3, $collection->resolve()['data']);
});
```
---
### Caching Considerations
API Resources don't affect caching strategy - they transform data at response time. Cache storage remains the same:
```php
// Cache raw model data (not transformed resources)
$cached = Cache::remember('team-members:all', 3600, function () {
return TeamMember::with('role')->get();
});
// Transform on response
return response()->json(TeamMemberResource::collection($cached));
```
---
### Error Response Handling
Error responses remain unchanged (no `"data"` wrapper):
```php
// Validation errors
return response()->json([
'message' => 'The given data was invalid.',
'errors' => $validator->errors(),
], 422);
// Not found
return response()->json([
'message' => 'Resource not found',
], 404);
```
---
### Scribe Documentation Updates
Update all `@response` annotations to show new format:
```php
/**
* @response {
* "data": {
* "id": "550e8400-e29b-41d4-a716-446655440000",
* "name": "John Doe"
* }
* }
*/
```
---
### Migration Steps
1. **Phase 1: Resources** - Create all resource classes
2. **Phase 2: Controllers** - Update one controller at a time, run tests
3. **Phase 3: Frontend** - Update API client helper, then each endpoint
4. **Phase 4: Tests** - Update all test assertions
5. **Phase 5: Docs** - Regenerate Scribe documentation
---
### Rollback Plan
Since this is a breaking change for frontend:
- Commit after each controller update
- Run full test suite before next controller
- If critical issue found, revert specific controller commit

## Why
The Headroom API currently returns raw JSON responses without a standardized wrapper. This violates the architecture specification (docs/headroom-architecture.md, lines 315-393) which mandates Laravel API Resources for consistent JSON structure. This technical debt creates several problems:
1. **Inconsistent Response Format**: Some endpoints return arrays, others objects, making client-side parsing error-prone
2. **No Future-Proofing**: Adding metadata (pagination, relationships, meta) requires breaking changes later
3. **Missing Data Wrapper**: Architecture requires `"data"` key for all responses to support future transformations
4. **No Resource Abstraction**: Direct model exposure limits ability to transform data without breaking clients
Since the application is pre-production and not in active use, we should fix this now to avoid permanent technical debt.
## What Changes
### Breaking Changes
- **BREAKING**: All API responses will be wrapped in `"data"` key
- **BREAKING**: Collections will use Laravel's resource collection format with `"data"` array
- **BREAKING**: Frontend API client must unwrap `response.data` instead of direct access
### New Components
- Create `app/Http/Resources/` directory structure
- Create 11 API Resource classes for consistent transformation
- Create base `BaseResource` with common formatting utilities
### Updated Components
- Update 6 controllers to use API Resources instead of `response()->json()`
- Update 63 backend tests to expect `"data"` wrapper in responses
- Update frontend API client to handle new response format
- Regenerate Scribe API documentation
## Capabilities
### New Capabilities
- `api-resource-standard`: Standardize all API responses using Laravel API Resources with consistent `"data"` wrapper
### Modified Capabilities
- *(none - this is a refactoring change, no functional requirements change)*
## Impact
### Backend (Laravel)
- **Files Created**: 11 new resource classes in `app/Http/Resources/`
- **Files Modified**: 6 controllers in `app/Http/Controllers/Api/`
- **Tests Updated**: 63 feature tests
- **New Tests**: 11+ unit tests for resource classes
### Frontend (SvelteKit)
- **Files Modified**: API client in `src/lib/api/` directory
- **Breaking**: All API calls must access `response.json().data` instead of `response.json()`
### Documentation
- **Regenerated**: Scribe API docs will show new response format
### Dependencies
- No new dependencies required (Laravel's built-in API Resources)
### Performance
- Minimal impact - API Resources add negligible overhead
- Slight improvement: Consistent caching keys can be optimized

## ADDED Requirements
### Requirement: API Response Standardization
All API responses MUST follow Laravel API Resource format with consistent `"data"` wrapper.
#### Scenario: Single resource response
- **WHEN** an API endpoint returns a single model
- **THEN** the response MUST have a `"data"` key containing the resource
- **AND** the resource MUST include all required fields defined in the resource class
**Example:**
```json
{
"data": {
"id": "550e8400-e29b-41d4-a716-446655440000",
"name": "John Doe",
"role": {
"id": 1,
"name": "Backend Developer"
},
"hourly_rate": 150.00,
"active": true,
"created_at": "2026-02-01T10:00:00Z"
}
}
```
#### Scenario: Collection response
- **WHEN** an API endpoint returns multiple models
- **THEN** the response MUST have a `"data"` key containing an array
- **AND** each item in the array MUST follow the single resource format
**Example:**
```json
{
"data": [
{
"id": "550e8400-e29b-41d4-a716-446655440000",
"name": "John Doe",
"role": { "id": 1, "name": "Backend Developer" },
"hourly_rate": 150.00,
"active": true,
"created_at": "2026-02-01T10:00:00Z"
},
{
"id": "660e8400-e29b-41d4-a716-446655440001",
"name": "Jane Smith",
"role": { "id": 2, "name": "Frontend Developer" },
"hourly_rate": 140.00,
"active": true,
"created_at": "2026-02-01T10:00:00Z"
}
]
}
```
#### Scenario: Nested relationships
- **WHEN** a resource has relationships (e.g., TeamMember has Role)
- **THEN** the relationship MUST be nested within the resource
- **AND** the nested resource SHOULD also follow the standard format
#### Scenario: Error responses
- **WHEN** an error occurs (validation, not found, etc.)
- **THEN** the response format remains unchanged (no `"data"` wrapper for errors)
- **AND** errors continue to use standard Laravel error format:
```json
{
"message": "The given data was invalid.",
"errors": {
"field": ["Error message"]
}
}
```
