This is a guidance skill, not a tool. When you build a Node.js server, REST or GraphQL API, or microservice, the agent loads it and follows its best-practice list: TypeScript, custom error classes, input validation, environment variables, structured logging, rate limiting, graceful shutdown, health checks and more.

The worked examples live in two reference files that the agent reads when the main file is not enough. It bundles no scripts. For testing it points to a separate skill, javascript-testing-patterns.

Good for

Developers starting a Node.js API or microservice
Teams that want Claude to follow one set of backend conventions
Anyone adding auth, rate limiting or caching to an Express or Fastify app

Questions

What does nodejs-backend-patterns do?

It gives Claude a set of Node.js backend conventions and worked examples: Express and Fastify, middleware, error handling, authentication, database integration and API response format.

How do I install nodejs-backend-patterns?

Use the install box above. The skill is three markdown files: SKILL.md and two reference files.

Does it include testing guidance?

Not in these files. SKILL.md sends testing questions to the javascript-testing-patterns skill, which is a separate skill.

Does it need an API key or scripts?

No key is named, and the folder bundles no scripts. The code samples in the reference files read database settings from environment variables, which are placeholders for your own project.

Is nodejs-backend-patterns safe?

It is text guidance with no scripts, so it does nothing on its own. The agent will still write code in your project that follows it, so review that code like any other, especially auth and database changes.

Express or Fastify?

The skill covers both and does not pick one. It describes Express as the minimalist framework and Fastify as the high-performance one.
