# H-07 API Gateway Integration - Complete Summary

## Mission Status: COMPLETE ✓

Successfully integrated all 5 feature routes into the Express.js API gateway with comprehensive authentication, error handling, and integration tests.

---

## Completion Checklist

### 1. Route Registration ✓
All 5 feature routes are properly imported and registered in `/home/user/navidocs/server/index.js`:

```javascript
import maintenanceRoutes from './routes/maintenance.js';  // NEW - Was missing!
import camerasRoutes from './routes/cameras.js';
import contactsRoutes from './routes/contacts.js';
import expensesRoutes from './routes/expenses.js';
import inventoryRoutes from './routes/inventory.js';

// Routes registered at:
app.use('/api/maintenance', maintenanceRoutes);      // NEW
app.use('/api/cameras', camerasRoutes);
app.use('/api/contacts', contactsRoutes);
app.use('/api/expenses', expensesRoutes);
app.use('/api/inventory', inventoryRoutes);
```

**Key Finding**: The maintenance routes were missing from the original server/index.js. This has been corrected.

---

### 2. Authentication Middleware ✓

#### Middleware Location
- **Primary**: `/home/user/navidocs/server/middleware/auth.middleware.js`
  - Comprehensive JWT authentication with audit logging
  - Functions: `authenticateToken`, `optionalAuth`, `requireEmailVerified`, `requireActiveAccount`, `requireOrganizationMember`, `requireOrganizationRole`, `requireEntityPermission`, `requireSystemAdmin`

#### Routes Protected
All feature routes now have `authenticateToken` middleware:

| Route | File | Auth Middleware | Status |
|-------|------|-----------------|--------|
| Inventory | inventory.js | authenticateToken (auth.js) | ✓ Verified |
| Maintenance | maintenance.js | authenticateToken (auth.middleware.js) | ✓ Verified |
| Cameras | cameras.js | authenticateToken (auth.middleware.js) | ✓ Updated |
| Contacts | contacts.js | authenticateToken (auth.middleware.js) | ✓ Verified |
| Expenses | expenses.js | authenticateToken (auth.middleware.js) | ✓ Updated |

**Updates Made**:
- Added `authenticateToken` to all camera routes (POST, GET list, GET stream, PUT, DELETE, proxy)
- Added `authenticateToken` to all expense routes (POST, GET, GET pending, GET split, PUT, PUT approve, DELETE, OCR)
- Webhook route (`POST /webhook/:token`) intentionally excludes authentication for Home Assistant integration

---

### 3. CORS Configuration ✓

**Location**: `/home/user/navidocs/server/index.js` (lines 44-47)

```javascript
app.use(cors({
  origin: NODE_ENV === 'production' ? process.env.ALLOWED_ORIGINS?.split(',') : '*',
  credentials: true
}));
```

**Features**:
- Development: Allows all origins (`*`)
- Production: Uses `ALLOWED_ORIGINS` environment variable
- Credentials support enabled for authenticated requests

---

### 4. Error Handling Middleware ✓

**Location**: `/home/user/navidocs/server/index.js` (lines 159-166)

```javascript
app.use((err, req, res, next) => {
  console.error('Error:', err);
  res.status(err.status || 500).json({
    error: err.message || 'Internal server error',
    ...(NODE_ENV === 'development' && { stack: err.stack })
  });
});
```

**Features**:
- Global error handler catches all unhandled errors
- Status code support (defaults to 500)
- Stack trace included in development mode
- Error messages sent to client

---

### 5. Rate Limiting ✓

**Location**: `/home/user/navidocs/server/index.js` (lines 57-65)

```javascript
const limiter = rateLimit({
  windowMs: parseInt(process.env.RATE_LIMIT_WINDOW_MS || '900000'), // 15 minutes
  max: parseInt(process.env.RATE_LIMIT_MAX_REQUESTS || '100'),
  standardHeaders: true,
  legacyHeaders: false,
  message: 'Too many requests, please try again later'
});

app.use('/api/', limiter);
```

**Configuration**:
- Window: 15 minutes (900,000 ms) - configurable via environment variable
- Limit: 100 requests per window - configurable via environment variable
- Applied to all `/api/` routes for comprehensive protection

---

### 6. Request Validation ✓

All routes implement comprehensive validation:

#### Inventory Routes
- Required: `boat_id`, `name`
- Optional: `category`, `purchase_date`, `purchase_price`, `depreciation_rate`
- File validation: Images only (JPEG, PNG, GIF, WebP), max 5MB

#### Maintenance Routes
- Required: `boatId`, `service_type`, `date`
- Date format: YYYY-MM-DD validation
- Optional: `provider`, `cost`, `next_due_date`, `notes`

#### Cameras Routes
- Required: `boatId`, `camera_name`, `rtsp_url`
- URL format validation: RTSP/HTTP URLs only
- Boat access verification

#### Contacts Routes
- Required: `organizationId`, `name`
- Optional: `type` (marina/mechanic/vendor), `phone`, `email`, `address`, `notes`
- Email and phone format validation

#### Expenses Routes
- Required: `boatId`, `amount`, `date`, `category`
- Currency validation: EUR, USD, GBP only
- Amount validation: Must be positive
- File validation: JPEG, PNG, WebP, PDF, max 10MB
- Date format: YYYY-MM-DD
