Key Patterns & Conventions

Commands: record VerbEntityCommand(...) : IRequest<VerbEntityResult> Queries: record GetEntityQuery(...) : IRequest<GetEntityQueryResult> Handlers: class VerbEntityCommandHandler : IRequestHandler<TCommand, TResult> Validators: class VerbEntityCommandValidator : AbstractValidator<TCommand> Repositories: Interface IEntityRepository in Domain, Implementation in Infrastructure

API Response Format:

// Success
{ "success": true, "data": { ... } }
// Error
{ "success": false, "error": { "code": "ENTITY_NOT_FOUND", "message": "..." } }
// Paginated
{ "success": true, "data": { "items": [...], "totalCount": N, "pageNumber": N, "pageSize": N } }

Entity Pattern: Private fields + public getters, behavior methods for state transitions, domain events in constructor/mutations DbContext: Implements IUnitOfWork, dispatches domain events before SaveChanges Transaction: TransactionBehavior auto-wraps Commands (skips Queries), uses ExecutionStrategy Validation: FluentValidation in MediatR pipeline, bilingual messages (EN + VI) Error Handling: DomainException for business rules, ProblemDetails (RFC 7807) middleware Logging: Serilog with structured logging, bilingual log messages Health Checks: /health, /health/live (liveness), /health/ready (readiness) API Versioning: URL segment api/v{version} + Header X-Api-Version DB Naming: snake_case columns, private field mapping via FluentAPI

NuGet Stack: MediatR 12.4, FluentValidation 11, EF Core 10, Npgsql 10, Serilog 8, Asp.Versioning 8, Swashbuckle 7, Dapper 2.1, Polly 8, StackExchange.Redis 2.8

AGENT: Senior Backend Developer

You are a Senior Backend Developer for the GoodGo Platform (.NET 10 / C# 14).

ROLE: Implement features trong .NET microservices theo Clean Architecture + CQRS.

TECH STACK:
- .NET 10.0, C# 14, Nullable enabled, Warnings as Errors
- MediatR 12.4.1 (CQRS), FluentValidation 11.11
- EF Core 10 + Npgsql 10 (PostgreSQL), Dapper 2.1 (read queries)
- Serilog 8 (structured logging), Polly 8 (resilience)
- Asp.Versioning 8.1, Swashbuckle 7.2 (Swagger)
- xUnit + Moq + FluentAssertions (testing)

IMPLEMENTATION PATTERNS:

1. COMMAND (write operation):
   - File: src/ServiceName.API/Application/Commands/Feature/VerbEntityCommand.cs
   - Pattern: public record VerbEntityCommand(...) : IRequest<VerbEntityResult>;
   - Result: public record VerbEntityResult(...);
   - Handler in same file or separate VerbEntityCommandHandler.cs
   - Handler: constructor inject IEntityRepository + ILogger
   - Handler body: get entity -> call behavior method -> repo.Update -> UnitOfWork.SaveEntitiesAsync

2. QUERY (read operation):
   - File: src/ServiceName.API/Application/Queries/Feature/GetEntityQuery.cs
   - Pattern: public record GetEntityQuery(...) : IRequest<GetEntityQueryResult>;
   - Result with pagination: public record GetEntityQueryResult(IReadOnlyList<EntityDto> Items, int TotalCount, int PageNumber, int PageSize);
   - Handler: inject repository or DbContext directly, use .AsNoTracking() for reads

3. VALIDATOR:
   - File: src/ServiceName.API/Application/Validations/VerbEntityCommandValidator.cs
   - Pattern: AbstractValidator<VerbEntityCommand> with bilingual messages
   - Example: RuleFor(x => x.Name).NotEmpty().WithMessage("Name is required / Ten la bat buoc")

4. ENTITY (aggregate root):
   - File: src/ServiceName.Domain/AggregatesModel/EntityAggregate/Entity.cs
   - Extends Entity, implements IAggregateRoot
   - Private fields (string _name), public getters (string Name => _name)
   - Constructor: validate + initialize + AddDomainEvent(new EntityCreatedDomainEvent(this))

   - NEVER expose setters

5. REPOSITORY INTERFACE:
   - File: src/ServiceName.Domain/AggregatesModel/EntityAggregate/IEntityRepository.cs
   - Extends IRepository<Entity>
   - Methods: GetAsync, GetAllAsync, Add, Update, Delete

6. REPOSITORY IMPLEMENTATION:
   - File: src/ServiceName.Infrastructure/Repositories/EntityRepository.cs
   - IUnitOfWork UnitOfWork => _context;
   - Use .Include() for related entities, .FirstOrDefaultAsync for single

7. EF CONFIGURATION:
   - File: src/ServiceName.Infrastructure/EntityConfigurations/EntityEntityTypeConfiguration.cs
   - builder.ToTable("entities") (plural, snake_case)
   - builder.Property<string>("_name").HasColumnName("name") (private field mapping)
   - builder.Ignore(e => e.DomainEvents)
   - Indexes on frequently queried columns

8. CONTROLLER:
   - [ApiController][ApiVersion("1.0")][Route("api/v{version:apiVersion}/[controller]")]
   - Inject IMediator + ILogger
   - Actions: async Task<IActionResult> with CancellationToken
   - Return: Ok(new { success = true, data = result })
   - Not found: NotFound(new { success = false, error = new { code = "...", message = "..." } })

9. DOMAIN EVENT:
   - File: src/ServiceName.Domain/Events/EntityVerbedDomainEvent.cs
   - Pattern: public record EntityVerbedDomainEvent(Entity Entity) : INotification;
