🗄️ Database Schema

• createdAt - Timestamp
• updatedAt - Timestamp
• createdBy - User ID (optional)
• updatedBy - User ID (optional)
• deletedAt - Soft delete (nullable)

Tables Created

1. master_options - ค่าตัวเลือกหลัก
2. locations - ข้อมูลสถานที่
3. industrial_estates - นิคมอุตสาหกรรม
4. audit_logs - บันทึกการทำงาน

🏗️ Architecture Pattern

Module Structure

src/modules/{module-name}/
├── model.ts      - Elysia type definitions
├── service.ts    - Business logic & database operations
├── controller.ts - API route handlers
└── index.ts      - Module exports

Design Principles

• Separation of Concerns: แยก model, service, controller ชัดเจน
• Branch Scoping: ทุก query ถูก filter โดย branchId
• Soft Delete: ใช้ deletedAt แทนการลดจริง
• Multi-tenant Ready: เตรียมพร้อมสำหรับ RBAC/ABAC
• Type Safety: ใช้ TypeScript + Elysia types

---

🔐 Security & Access Control

Branch Middleware

ทุก module ใช้ branchMiddleware ที่ inject:

• currentBranchId - Branch ปัจจุบัน
• userId - User ID
• userGroups - User groups/roles
• accessibleBranches - Branches ที่มีสิทธิ์เข้าถึง

Permission Checks

• Standard Modules: ต้องมี branch access
• Audit Logs: Admin/Superadmin/Auditor only

📊 API Response Format

Success Response

{
  "success": true,
  "data": { ... },
  "count": 10,
  "message": "Success message"
}

Error Response

📝 Notes

Current Status

• ✅ All core infrastructure modules completed
• ✅ Database schema updated
• ✅ Branch scoping implemented
• ✅ Audit logging ready
• ⚠️ Middleware needs proper user authentication integration
• ⚠️ Some TypeScript errors remain (middleware typing issues)

Known Issues

1. Middleware Typing: currentBranchId, userId, userGroups ยังไม่ถูก inject อย่างถูกต้อง
2. Authentication: ต้องเชื่อมต่อกับ Keycloak หรือ auth system
3. Migration: ต้องสร้าง migration script สำหรับ production

Next Steps

1. Fix middleware typing issues
2. Integrate with authentication system
3. Create database migration script
4. Add comprehensive tests
5. Implement Customer & Quotation modules
6. Add ERP integration layer
