What architectural styles are included in this skill?

The skill focuses on Layered Architecture and Dependency Injection patterns to ensure your backend is scalable and easy to test.

Does this skill support both Express and Fastify?

Yes, it provides optimized configurations and implementation patterns for both the Express and Fastify frameworks.

Does it include database integration examples?

Yes, it provides repository patterns specifically designed for integrating with SQL (like PostgreSQL) and NoSQL databases.

Is TypeScript required to use these patterns?

While these patterns can be adapted for JavaScript, they are optimized for TypeScript to ensure type safety across controllers, services, and repositories.

API開発

Implements scalable, production-ready Node.js backend architectures using Express and Fastify with industry-standard design patterns.

概要

This skill equips Claude with the expertise to design and build sophisticated Node.js backend services using modern frameworks and architectural principles. It provides standardized patterns for layered architectures, dependency injection, and type-safe API development. Whether utilizing Express for its minimalist approach or Fastify for high-performance needs, this skill ensures best practices for middleware implementation, JWT authentication, error handling, and repository-based data persistence. It is essential for developers architecting robust microservices, REST APIs, or GraphQL backends that require long-term maintainability and performance.
