Does it support specific frameworks like Express or Fastify?

Yes, it provides universal architectural patterns such as layered structures (API, Services, Repositories) that are highly effective across all major Node.js frameworks.

How does this improve the testability of my code?

By advocating for a 'Pure Core' approach, it helps you isolate business logic from I/O side effects, making it significantly easier to write deterministic unit tests.

How does this skill handle TypeScript-specific features?

It leverages TypeScript's advanced type system to implement robust error handling and clear interfaces, replacing 'magic numbers' and 'any' types with meaningful constants and typed results.

Can it help me break down complex, nested logic?

Absolutely. The skill specializes in simplifying conditionals using early returns and extracting shared logic to ensure functions remain single-purpose and readable.

開発者ツール

Enforces industry-standard clean code principles and functional architectural patterns for TypeScript and Node.js development.

概要

This skill transforms Claude into a senior software architect specializing in TypeScript and Node.js. It provides specific guidance on implementing core engineering principles like DRY, KISS, and YAGNI to eliminate technical debt and improve maintainability. By advocating for a 'Pure Core, Impure Shell' architecture and robust, typed error handling, this skill ensures that your backend services are not only functional but also scalable and highly testable through standardized code organization and naming conventions.
