# Phase 2 Backend Checkpoint - COMPLETE ✅
|
||||
|
||||
**Date**: 2026-02-05
|
||||
**Status**: Phase 2 Backend 100% Complete
|
||||
|
||||
## What Was Completed
|
||||
|
||||
### 1. BUN ORM Migration (COMPLETE)
|
||||
- ✅ Converted all storage layer from GORM to BUN
|
||||
- ✅ Generated 7 BUN models from DBML schema using `relspec` tool
|
||||
- ✅ Updated `pkg/storage/db.go` with BUN connection handling
|
||||
- ✅ Converted `pkg/storage/repository.go` to use BUN queries
|
||||
- ✅ Updated seed data to use BUN models
|
||||
|
||||
**Generated Models** (`pkg/models/`):
|
||||
- `sql_public_users.go` → `ModelPublicUser`
|
||||
- `sql_public_api_keys.go` → `ModelPublicAPIKey`
|
||||
- `sql_public_hooks.go` → `ModelPublicHook`
|
||||
- `sql_public_whatsapp_accounts.go` → `ModelPublicWhatsappAccount`
|
||||
- `sql_public_event_logs.go` → `ModelPublicEventLog`
|
||||
- `sql_public_sessions.go` → `ModelPublicSession`
|
||||
- `sql_public_message_cache.go` → `ModelPublicMessageCache`
|
||||
|
||||
### 2. ResolveSpec API Integration (COMPLETE)
|
||||
- ✅ Created `pkg/api/server.go` with ResolveSpec framework
|
||||
- ✅ Created `pkg/api/security.go` with JWT authentication
|
||||
- ✅ Auto-generates REST CRUD endpoints for all models
|
||||
- ✅ Implements row-level security (multi-tenancy)
|
||||
- ✅ Uses Gorilla Mux router with ResolveSpec handler
|
||||
|
||||
**Key Implementation Details**:
|
||||
```go
|
||||
// Create model registry and register all models
|
||||
registry := modelregistry.NewModelRegistry()
|
||||
registry.RegisterModel("public.users", &models.ModelPublicUser{})
|
||||
// ... register all 7 models
|
||||
|
||||
// Create BUN adapter and handler
|
||||
bunAdapter := database.NewBunAdapter(db)
|
||||
handler := restheadspec.NewHandler(bunAdapter, registry)
|
||||
|
||||
// Security provider handles JWT auth
|
||||
secProvider := NewSecurityProvider(cfg.API.JWTSecret, db)
|
||||
```
|
||||
|
||||
### 3. Configuration Updates (COMPLETE)
|
||||
- ✅ Added `APIConfig` struct to `pkg/config/config.go`:
|
||||
```go
|
||||
type APIConfig struct {
|
||||
Enabled bool // Enable Phase 2 API server
|
||||
Host string // API server host (default: 0.0.0.0)
|
||||
Port int // API server port (default: 8080)
|
||||
JWTSecret string // Secret for JWT signing
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Code Cleanup (COMPLETE)
|
||||
- ✅ Deleted deprecated `pkg/auth/` package
|
||||
- ✅ Deleted deprecated `pkg/webserver/` package
|
||||
- ✅ All functionality now via ResolveSpec
|
||||
|
||||
### 5. SQL Migrations (COMPLETE)
|
||||
- ✅ Generated PostgreSQL migration: `sql/postgres/001_init_schema.up.sql`
|
||||
- ✅ Created rollback script: `sql/postgres/001_init_schema.down.sql`
|
||||
- ✅ Includes all tables, indexes, constraints, foreign keys
|
||||
|
||||
### 6. Example Code (COMPLETE)
|
||||
- ✅ Updated `examples/phase2_integration.go`
|
||||
- ✅ Shows how to start API server with ResolveSpec
|
||||
|
||||
## Database Schema
|
||||
|
||||
**7 Tables with Full Relationships**:
|
||||
1. `users` - User accounts (admin, user roles)
|
||||
2. `api_keys` - API authentication keys
|
||||
3. `hooks` - Webhook configurations
|
||||
4. `whatsapp_accounts` - Connected WhatsApp accounts
|
||||
5. `event_logs` - Activity audit trail
|
||||
6. `sessions` - User login sessions
|
||||
7. `message_cache` - WhatsApp message history
|
||||
|
||||
**Key Constraints**:
|
||||
- Foreign keys: api_keys → users, hooks → users, etc.
|
||||
- Unique constraints: username, email, api_key, phone_number
|
||||
- Soft delete support: deleted_at columns
|
||||
- Indexes on all foreign keys and frequently queried fields
|
||||
|
||||
## API Endpoints (Auto-Generated)
|
||||
|
||||
**Authentication** (Manual):
|
||||
```
|
||||
POST /api/v1/auth/login - Login to get JWT token
|
||||
POST /api/v1/auth/logout - Logout and invalidate token
|
||||
GET /health - Health check
|
||||
```
|
||||
|
||||
**CRUD Endpoints** (Auto-generated by ResolveSpec for each model):
|
||||
```
|
||||
GET /api/v1/{resource} - List (with filtering, pagination)
|
||||
POST /api/v1/{resource} - Create
|
||||
GET /api/v1/{resource}/:id - Get by ID
|
||||
PUT /api/v1/{resource}/:id - Update
|
||||
DELETE /api/v1/{resource}/:id - Delete (soft delete)
|
||||
```
|
||||
|
||||
Resources: `users`, `api_keys`, `hooks`, `whatsapp_accounts`, `event_logs`, `sessions`, `message_cache`
|
||||
|
||||
## Security Features
|
||||
|
||||
1. **JWT Authentication** - Stateless token-based auth
|
||||
2. **Row-Level Security** - Users only see their own data
|
||||
3. **Multi-Tenancy** - Automatic user_id filtering
|
||||
4. **API Keys** - Alternative authentication method
|
||||
5. **Session Management** - Track active sessions with expiration
|
||||
6. **Bcrypt Passwords** - Secure password hashing
|
||||
|
||||

## How to Run Phase 2 API Server
|
||||
|
||||
```bash
|
||||
# 1. Create config.json with database settings
|
||||
{
|
||||
"api": {
|
||||
"enabled": true,
|
||||
"host": "0.0.0.0",
|
||||
"port": 8080,
|
||||
"jwt_secret": "your-secret-key"
|
||||
},
|
||||
"database": {
|
||||
"type": "postgres",
|
||||
"host": "localhost",
|
||||
"port": 5432,
|
||||
"username": "postgres",
|
||||
"password": "password",
|
||||
"database": "whatshooked"
|
||||
}
|
||||
}
|
||||
|
||||
# 2. Run migrations
|
||||
psql -U postgres -d whatshooked -f sql/postgres/001_init_schema.up.sql
|
||||
|
||||
# 3. Build and run
|
||||
go build -o whatshooked examples/phase2_integration.go
|
||||
./whatshooked
|
||||
|
||||
# 4. Test API
|
||||
curl -X POST http://localhost:8080/api/v1/auth/login \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"username":"admin","password":"admin123"}'
|
||||
```
|
||||
|
||||
## Default Credentials
|
||||
|
||||
- **Username**: `admin`
|
||||
- **Password**: `admin123`
|
||||
- **Role**: `admin`
|
||||
|
||||
⚠️ Change default password after first login!

## Next Phase: Frontend UI
|
||||
|
||||
**Status**: Ready to start
|
||||
|
||||
The backend is complete and provides all necessary API endpoints. Next steps:
|
||||
1. Create React frontend application
|
||||
2. Implement login/authentication UI
|
||||
3. Build dashboard for managing hooks, accounts
|
||||
4. Add WhatsApp account connection UI
|
||||
5. Event log viewer
|
||||
6. User management for admins
|
||||
|
||||
All backend APIs are ready to consume from the frontend.
