Which backend frameworks are supported?

While the default implementation patterns use Express and TypeScript, the architectural principles can be adapted to any modern Node.js backend framework.

What API architecture does this skill follow?

The skill follows strict RESTful design principles, utilizing standard HTTP methods (GET, POST, PATCH, PUT, DELETE) and standardized JSON response formats.

Can I use this for database schema design?

Absolutely. The skill includes patterns for defining database schemas (using tools like Drizzle and SQLite) that map directly to your API resources.

Does it support end-to-end type safety?

Yes, it encourages a workflow where types are defined in a shared package, ensuring that both the server implementation and the frontend client remain in sync.

How does it handle error management?

It implements a standardized error response format including an error message and optional details, mapped to appropriate HTTP status codes like 400, 404, and 500.

API開発

Architects and implements production-ready RESTful APIs with end-to-end type safety from database to frontend.

The API Designer skill transforms Claude into a specialized backend architect focused on building robust, scalable, and type-safe communication layers. It streamlines the development process by providing a structured workflow: defining shared TypeScript types, creating database schemas, implementing Express routes with standardized HTTP status codes, and generating matching frontend API clients. This ensures consistency across the entire stack, reduces integration errors, and adheres to industry-standard RESTful principles for professional-grade backend development.
