How does the Node.js Expert skill handle database operations?

It includes pre-defined patterns for Prisma and TypeORM, focusing on preventing N+1 problems, managing transactions, and implementing cursor-based pagination.

How does the skill improve error handling?

It provides async handler wrappers to prevent unhandled promise rejections and establishes a centralized error-handling middleware with custom error classes.

When does this skill automatically activate?

It triggers automatically when Claude detects Node.js backend files, framework dependencies in package.json, or keywords like 'express', 'nestjs', and 'api route'.

Does this skill help with API security?

Yes, it proactively implements security best practices including Helmet headers, CORS configuration, rate limiting, and input sanitization.

Which Node.js frameworks are supported by this skill?

The skill provides specialized patterns and best practices for Express, NestJS, and Fastify, covering both MVC and modular architectures.

API開発

Architects production-grade Node.js backends using industry-leading patterns for Express, NestJS, and Fastify.

概要

The Node.js Expert skill transforms Claude into a senior backend architect specialized in the Node.js ecosystem. It provides immediate access to standardized project structures, robust error-handling wrappers, and secure API design patterns. By automating the implementation of complex features like NestJS modules, Prisma transactions, and Zod validation, it ensures your backend is scalable, secure, and follows a strict Test-Driven Development (TDD) workflow. This skill is essential for teams looking to maintain high code quality and consistent architecture across distributed API services.
