|
|
|
|
## Project Status: ✅ CORE FUNCTIONALITY COMPLETE
|
|
|
|
### Completed Implementation (August 20, 2025)
|
|
|
|
#### 🏗️ **Architecture**
|
|
- **Framework**: ASP.NET Core 9.0 Web API + MVC
|
|
- **Database**: SQLite with Entity Framework Core
|
|
- **Authentication**: Dual-mode (Cookie for Admin Panel + JWT for API)
|
|
- **Structure**: Clean separation between Admin Panel (MVC) and Client API (Web API)
|
|
|
|
#### 🗄️ **Database Schema** ✅
|
|
- **Tables**: Users, Categories, Products, ProductPhotos, Orders, OrderItems, CryptoPayments
|
|
- **Relationships**: Proper foreign keys and indexes
|
|
- **Enums**: ProductWeightUnit, OrderStatus, CryptoCurrency, PaymentStatus
|
|
- **Default Data**: Admin user (admin/admin) auto-seeded
|
|
|
|
#### 🔐 **Authentication System** ✅
|
|
- **Admin Panel**: Cookie-based authentication for staff users
|
|
- **Client API**: JWT authentication ready for client applications
|
|
- **Security**: PBKDF2 password hashing, proper claims-based authorization
|
|
- **Users**: Staff-only user management (no customer accounts stored)
|
|
|
|
#### 🛒 **Admin Panel (MVC)** ✅
|
|
- **Dashboard**: Overview with statistics and quick actions
|
|
- **Categories**: Full CRUD operations working
|
|
- **Products**: Full CRUD operations working with photo upload support
|
|
- **Users**: Staff user management working
|
|
- **Orders**: Order management and status tracking
|
|
- **Views**: Bootstrap-based responsive UI with proper form binding
|
|
|
|
#### 🔌 **Client API (Web API)** ✅
|
|
- **Catalog Endpoints**:
|
|
- `GET /api/catalog/categories` - Public category listing
|
|
- `GET /api/catalog/products` - Public product listing
|
|
- **Order Management**:
|
|
- `POST /api/orders` - Create orders by identity reference
|
|
- `GET /api/orders/by-identity/{id}` - Get client orders
|
|
- `POST /api/orders/{id}/payments` - Create crypto payments
|
|
- `POST /api/orders/payments/webhook` - BTCPay Server webhooks
|
|
|
|
#### 💰 **Multi-Cryptocurrency Support** ✅
|
|
- **Supported Currencies**: BTC, XMR (Monero), USDT, LTC, ETH, ZEC (Zcash), DASH, DOGE
|
|
- **BTCPay Server Integration**: Complete client implementation with webhook processing
|
|
- **Privacy Design**: No customer personal data stored, identity reference only
|
|
- **Payment Workflow**: Order → Payment generation → Blockchain monitoring → Status updates
|
|
|
|
#### 📦 **Features Implemented**
|
|
- **Product Management**: Name, description, weight/units, pricing, categories, photos
|
|
- **Order Workflow**: Creation → Payment → Processing → Shipping → Tracking
|
|
- **File Upload**: Product photo management with alt text support
|
|
- **Validation**: FluentValidation for input validation, server-side model validation
|
|
- **Logging**: Comprehensive Serilog logging to console and files
|
|
- **Documentation**: Swagger API documentation with JWT authentication
|
|
|
|
### 🔧 **Technical Lessons Learned**
|
|
|
|
#### **ASP.NET Core 9.0 Specifics**
|
|
1. **Model Binding Issues**: Views need explicit model instances (`new CreateDto()`) for proper binding
|
|
2. **Form Binding**: Using explicit `name` attributes more reliable than `asp-for` helpers in some cases
|
|
3. **Area Routing**: Requires proper route configuration and area attribute on controllers
|
|
4. **View Engine**: Runtime changes to views require application restart in Production mode
|
|
|
|
#### **Entity Framework Core**
|
|
1. **SQLite Works Well**: Handles all complex relationships and transactions properly
|
|
2. **Query Splitting Warning**: Multi-include queries generate warnings but work correctly
|
|
3. **Migrations**: `EnsureCreated()` sufficient for development, migrations better for production
|
|
4. **Decimal Precision**: Proper `decimal(18,2)` and `decimal(18,8)` column types for currency
|
|
|
|
#### **Authentication Architecture**
|
|
1. **Dual Auth Schemes**: Successfully implemented both Cookie (MVC) and JWT (API) authentication
|
|
2. **Claims-Based Security**: Works well for role-based authorization policies
|
|
3. **Password Security**: PBKDF2 with 100,000 iterations provides good security
|
|
4. **Session Management**: Cookie authentication handles admin panel sessions properly
|
|
|
|
#### **BTCPay Server Integration**
|
|
1. **Version Compatibility**: BTCPay Server Client v2.0 has different API than v1.x
|
|
2. **Package Dependencies**: NBitcoin version conflicts require careful package management
|
|
3. **Privacy Focus**: Self-hosted approach eliminates third-party data sharing
|
|
4. **Webhook Processing**: Proper async handling for payment status updates
|
|
|
|
#### **Development Challenges Solved**
|
|
1. **WSL Environment**: Required CMD.exe for .NET commands, file locking issues with hot reload
|
|
2. **View Compilation**: Views require app restart in Production mode to pick up changes
|
|
3. **Form Validation**: Empty validation summaries appear due to ModelState checking
|
|
4. **Static Files**: Proper configuration needed for product photo serving
|
|
|
|
### 🚀 **Current System Status**

|
|
- **Memory Usage**: Efficient with proper service scoping
|
|
- **Query Performance**: EF Core generates optimal SQLite queries
|
|

|
|
- **Encrypted Storage**: Passwords properly hashed with salt
|
|
