# Phase 2 Implementation Progress

## Completed ✅

### 1. Tool Documentation (tooldoc/)

Created comprehensive documentation for all libraries and frameworks:

- **CODE_GUIDELINES.md**: Complete coding standards, project structure, naming conventions, error handling, testing patterns, and best practices
- **RESOLVESPEC.md**: Detailed ResolveSpec integration guide including setup, API patterns, filtering, pagination, and security
- **ORANGURU.md**: Oranguru component library guide for enhanced Mantine components
- **REACT_MANTINE_TANSTACK.md**: Frontend framework integration guide with project structure and examples

### 2. Database Storage Layer (pkg/storage/)

Complete database abstraction with GORM support:

**Models** (storage/models.go):
- User: Authentication and user management
- APIKey: API key-based authentication
- Hook: Webhook registrations with user ownership
- WhatsAppAccount: WhatsApp account configurations per user
- EventLog: Audit trail for all operations
- Session: User session management
- MessageCache: WhatsApp message caching

**Database Management** (storage/db.go):
- PostgreSQL and SQLite support
- Connection pooling
- Auto-migration support
- Health check functionality

**Repository Pattern** (storage/repository.go):
- Generic repository with CRUD operations
- Specialized repositories for each model
- User-specific queries (by username, email)
- API key queries (by key, user)
- Hook and account filtering by user
- Event log queries with time-based filtering

**Seed Data** (storage/seed.go):
- Creates default admin user (username: admin, password: admin123)
- Safe to run multiple times

### 3. Authentication Package (pkg/auth/)

Full-featured authentication system:

**Core Auth** (auth/auth.go):
- JWT token generation and validation
- API key authentication
- Password hashing with bcrypt
- User login with credential verification
- API key creation and revocation
- Permission checking based on roles (admin, user, viewer)

**Middleware** (auth/middleware.go):
- AuthMiddleware: Requires authentication (JWT or API key)
- OptionalAuthMiddleware: Extracts user if present
- RoleMiddleware: Enforces role-based access control
- Context helpers for user extraction

### 4. Web Server Package (pkg/webserver/)

Complete REST API server with authentication:

**Server Setup** (webserver/server.go):
- Gorilla Mux router integration
- Authentication middleware
- Role-based route protection
- Public and protected routes
- Admin-only routes

**Core Handlers** (webserver/handlers.go):
- Health check endpoint
- User login with JWT
- Get current user profile
- Change password
- Create API key
- Revoke API key
- List users (admin)
- Create user (admin)

**CRUD Handlers** (webserver/handlers_crud.go):
- Hook management (list, create, get, update, delete)
- WhatsApp account management (list, create, get, update, delete)
- API key listing
- User management (get, update, delete - admin only)
- Ownership verification for all resources

### 5. API Endpoints

## Pending 📋

### 7-11. Frontend Implementation

The following items require frontend development:

- React frontend with Mantine and TanStack Start
- Oranguru integration for grids and forms
- User login interface
- API key management UI
- User-level hooks and WhatsApp account management UI

## How to Use

### 1. Database Setup

```go
import "git.warky.dev/wdevs/whatshooked/pkg/storage"
import "git.warky.dev/wdevs/whatshooked/pkg/config"

// Initialize database
cfg := &config.DatabaseConfig{
    Type:     "postgres", // or "sqlite"
    Host:     "localhost",
    Port:     5432,
    Username: "whatshooked",
    Password: "password",
    Database: "whatshooked",
}

err := storage.Initialize(cfg)
if err != nil {
    log.Fatal(err)
}

// Run migrations
err = storage.AutoMigrate()
if err != nil {
    log.Fatal(err)
}

// Seed default data (creates admin user)
err = storage.SeedData(context.Background())
if err != nil {
    log.Fatal(err)
}
```

### 2. Start Web Server

```go
import "git.warky.dev/wdevs/whatshooked/pkg/webserver"

// Create server with JWT secret
server, err := webserver.NewServer("your-secret-key-here")
if err != nil {
    log.Fatal(err)
}

// Start server
log.Fatal(server.Start(":8825"))
```

### 3. API Usage Examples

**Login**:
```bash
curl -X POST http://localhost:8825/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin123"}'
```

**Create Hook** (with JWT):
```bash
curl -X POST http://localhost:8825/api/v1/hooks \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My Webhook",
    "url": "https://example.com/webhook",
    "method": "POST",
    "events": ["message.received"],
    "active": true
  }'
```

**Create API Key**:
```bash
curl -X POST http://localhost:8825/api/v1/api-keys \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"Production API Key"}'
```

**Use API Key**:
```bash
curl http://localhost:8825/api/v1/hooks \
  -H "Authorization: ApiKey YOUR_API_KEY"
```

## Security Features

1. **Multi-tenancy**: Users can only access their own resources (hooks, API keys, accounts)
2. **Role-based Access Control**: Admin, user, and viewer roles with hierarchical permissions
3. **JWT Authentication**: Secure token-based authentication with 24-hour expiry
4. **API Key Authentication**: Alternative authentication for programmatic access
5. **Password Hashing**: Bcrypt with default cost for secure password storage
6. **Ownership Verification**: All CRUD operations verify resource ownership
7. **Audit Trail**: EventLog table for tracking all operations

## Next Steps

To complete Phase 2, implement the frontend:

1. **Initialize Frontend Project**:
   ```bash
   npm create @tanstack/start@latest
   cd frontend
   npm install @mantine/core @mantine/hooks @mantine/notifications @mantine/form @mantine/datatable
   npm install @warkypublic/oranguru
   npm install @tanstack/react-query axios
   ```

2. **Create Components**:
   - Login page
   - Dashboard layout with navigation
   - User profile page
   - API key management page
   - Hook management page (with Oranguru DataTable)
   - WhatsApp account management page

3. **Integrate with API**:
   - Setup axios with JWT token interceptor
   - Create API client modules
   - Implement TanStack Query for data fetching
   - Add error handling and loading states

4. **Build and Deploy**:
   - Build frontend: `npm run build`
   - Serve static files through Go server
   - Configure reverse proxy if needed
