# Phase 2 Update - New Backend Tools Applied

## What Changed

Based on the updated PLAN.md, I've applied the following new tools and requirements:

### ✅ Completed Updates:

#### 1. **Makefile Enhancement**

Updated the existing Makefile with new Phase 2 commands:

**New Commands Added:**
- `make build-ui` - Build frontend
- `make dev-ui` - Run frontend in dev mode
- `make generate-models` - Generate BUN models from DBML
- `make migrate / migrate-up / migrate-down` - Database migrations
- `make migrate-create NAME=<name>` - Create new migration
- `make setup-migrations` - Setup migration infrastructure
- `make seed` - Seed database with initial data
- `make install-relspecgo` - Install relspecgo tool
- `make install-tools` - Install all development tools

**Usage:**
```bash
make help  # See all available commands
```

#### 2. **DBML Schema Definition**

Created complete database schema in DBML format:

**File:** `sql/schema.dbml`

**Tables Defined:**
- users
- api_keys
- hooks
- whatsapp_accounts
- event_logs
- sessions
- message_cache

**Features:**
- All relationships defined
- Indexes specified
- Constraints (unique, not null, foreign keys)
- Cascade delete rules
- Soft delete support
- Timestamps with defaults

#### 3. **SQL Directory Structure**

Created organized SQL structure:

```
sql/
├── schema.dbml              # Main schema definition (DBML)
├── postgres/                # PostgreSQL migrations
│   ├── [timestamp]_*.up.sql
│   └── [timestamp]_*.down.sql
└── sqlite/                  # SQLite migrations
    ├── [timestamp]_*.up.sql
    └── [timestamp]_*.down.sql
```

#### 4. **Tool Documentation**

Created comprehensive documentation:

**New Files:**
- `tooldoc/RELSPECGO.md` - Complete relspecgo guide
  - Installation and usage
  - DBML syntax reference
  - Model generation workflow
  - Integration with ResolveSpec
  - Best practices

- `tooldoc/BUN_ORM.md` - Complete BUN ORM guide
  - Database setup (PostgreSQL & SQLite)
  - Model definition with tags
  - CRUD operations
  - Relationships (has-many, belongs-to, many-to-many)
  - Queries and filtering
  - Transactions
  - ResolveSpec integration
  - Performance tips
  - Testing patterns

## Next Steps

### Remaining Tasks:

1. **Convert from GORM to BUN** (High Priority)
   - Install BUN dependencies
   - Generate models from DBML using relspecgo
   - Update storage package to use BUN
   - Update repository implementations
   - Test all database operations

2. **Update WebServer** (High Priority)
   - Use ResolveSpec's server package directly
   - Leverage ResolveSpec's built-in security
   - Use ResolveSpec authentication features
   - Remove custom authentication (use ResolveSpec's)

3. **Create Migrations**
   - Generate SQL migrations from DBML
   - Create migration scripts
   - Setup migrate.sh script

4. **Frontend** (Medium Priority)
   - Initialize React + Mantine + TanStack Start project
   - Integrate Oranguru
   - Build UI components

## How to Use New Tools

### 1. Generate BUN Models

```bash
# Install relspecgo
make install-relspecgo

# Generate models from DBML
make generate-models

# This creates models in pkg/models/ from sql/schema.dbml
```

### 2. Create Migration

```bash
# Create new migration files
make migrate-create NAME=init_schema

# Edit the generated files in:
# - sql/postgres/[timestamp]_init_schema.up.sql
# - sql/postgres/[timestamp]_init_schema.down.sql
# - sql/sqlite/[timestamp]_init_schema.up.sql
# - sql/sqlite/[timestamp]_init_schema.down.sql
```

### 3. Run Migrations

```bash
# Setup migration infrastructure first
make setup-migrations

# Run migrations
make migrate-up

# Rollback
make migrate-down
```

### 4. Build Everything

```bash
# Build backend and frontend
make build

# Or separately
make build-backend  # Server + CLI
make build-ui       # Frontend only
```

## Updated Workflow

### Development Flow:

1. **Schema Changes:**
   ```bash
   # Edit sql/schema.dbml
   make generate-models
   make migrate-create NAME=my_change
   # Edit migration files
   make migrate-up
   ```

2. **Backend Development:**
   ```bash
   # Run tests
   make test
   
   # Lint code
   make lint
   
   # Run server
   make run-server
   ```

3. **Frontend Development:**
   ```bash
   # Run in dev mode
   make dev-ui
   
   # Build for production
   make build-ui
   ```

## Benefits of New Approach

### relspecgo + BUN:

1. **Single Source of Truth**: DBML defines everything
2. **Type Safety**: Generated Go models are type-safe
3. **Consistency**: Same schema for PostgreSQL and SQLite
4. **Documentation**: DBML serves as schema documentation
5. **Fast Development**: Auto-generate models and migrations
6. **SQL-First**: BUN is SQL-first, giving you control

### Makefile:

1. **Standardized Commands**: Same commands work across team
2. **Easy Onboarding**: `make help` shows everything
3. **Automation**: Complex tasks simplified
4. **Cross-Platform**: Works on Linux, macOS, Windows (WSL)

### ResolveSpec Integration:

1. **Less Code**: Built-in server, security, auth
2. **Best Practices**: Professional-grade patterns
3. **Maintenance**: Less custom code to maintain
4. **Features**: REST + ResolveSpec + security out of the box

## What's Different from Previous Implementation

### Before (GORM):
- Manual model definitions
- GORM tags
- Custom migrations
- More boilerplate

### After (BUN + DBML):
- DBML schema definition
- Auto-generated BUN models
- relspecgo for generation
- Standardized via Makefile
- Less boilerplate

### Before (Custom Server):
- Custom auth implementation
- Manual middleware
- Custom server setup

### After (ResolveSpec):
- Built-in authentication
- Built-in security
- Server package included
- Less custom code

## Next Implementation Steps

1. Run `make install-relspecgo`
2. Run `make generate-models`
3. Update pkg/storage to use BUN
4. Update pkg/webserver to use ResolveSpec server package
5. Create migration scripts
6. Test database operations
7. Initialize frontend project

The foundation is now properly set up following the updated PLAN.md requirements!
