What architecture pattern does this skill recommend?

It advocates for a layered architecture (Controller, Service, Repository) to ensure code testability, separation of concerns, and long-term maintainability.

How does it handle security?

The skill enforces a 'trust nothing' mindset, providing checklists for input validation, parameterized queries, secure password hashing, and JWT verification.

Does this skill work with modern runtimes like Bun and Deno?

Yes, it includes specific decision-making principles for selecting between Node.js, Bun, and Deno based on your project's performance and security requirements.

Can this skill help me migrate from Express to Fastify?

Absolutely. It provides a framework comparison and decision tree to help you understand the performance benefits and implementation differences between legacy and modern frameworks.

API Development

Guides developers through modern Node.js decision-making, framework selection, and secure architectural patterns for 2025.

The Node.js Best Practices skill transforms Claude into a senior backend architect capable of guiding complex technical decisions. Instead of providing generic code snippets, it focuses on 'thinking'—helping users choose the right framework (Hono, Fastify, NestJS) based on deployment targets, implementing robust layered architectures, and applying modern security and validation patterns. It is an essential companion for building production-grade, scalable, and maintainable JavaScript and TypeScript server-side applications.
