SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Backend development often suffers from tangled concerns where HTTP handlers start to take on validation, data access, and orchestration responsibilities. This Skill provides a framework and patterns to build robust, testable backend services for serverless environments by enforcing clean architecture, input validation, and dependency injection.

Core Features & Use Cases

  • Layered architecture: Handler → Service → Repository
  • Zod-based input validation and safe parsing
  • Dependency injection for testability and flexibility
  • Framework-agnostic patterns (Lambda, Hono, Express, serverless endpoints)
  • Use cases include API routes, validation layers, and service orchestration with data access

Quick Start

Create a minimal backend endpoint using the recommended pattern (handler → service → repository) with Zod validation and DI.

FAQPage Schema
How do I structure a serverless backend with clean architecture and separation of concerns?▼

Serverless backend clean architecture enforces a Handler → Service → Repository layering pattern to separate HTTP routing, orchestration, and data access. This keeps validation, business logic, and persistence distinct for testability.

How do I add input validation to Lambda or Hono endpoints?▼

Input validation in Lambda or Hono endpoints is applied via Zod safe parsing within the Handler layer. This ensures malformed data is rejected early before it reaches the Service layer.

Can I use dependency injection in Express APIs for better testability?▼

Dependency injection in Express APIs is supported by injecting repository or service dependencies into handlers. This abstracts data access and allows mocking dependencies during testing.

What is the best way to handle errors consistently across serverless API routes?▼

Consistent error handling across serverless API routes is implemented by standardizing error responses at the Handler layer. This prevents scattered try-catch blocks and ensures uniform API payloads.

Does this serverless backend pattern work with both Hono and Express?▼

The serverless backend pattern is framework-agnostic and works with Hono, Express, and AWS Lambda. It applies architectural layers universally without locking you into a specific framework.
