Node Best Practices

The node-best-practices skill provides a curated set of guidelines and patterns for writing robust, maintainable Node.js applications. It helps AI agents generate code that adheres to industry standards regarding security, performance, and architectural consistency.

When to use it

• Generating new backend services or APIs that require strict adherence to Node.js conventions.
• Refactoring legacy JavaScript codebases to improve readability and reduce technical debt.
• Ensuring security compliance when implementing sensitive data handling or authentication flows.
• Standardizing project structure across multiple microservices within a monorepo.

Key capabilities

• Enforces modern ES6+ syntax and module patterns (ESM/CJS).
• Validates code against common anti-patterns and performance bottlenecks.
• Recommends appropriate use of npm packages and dependency management strategies.
• Guides implementation of error handling, logging, and asynchronous control flow.

Example prompts

• "Generate a Node.js REST API endpoint using Express that follows best practices for input validation and error handling."
• "Refactor this legacy synchronous function into an async/await pattern while adhering to Node.js performance guidelines."
• "Create a project structure for a scalable microservice that aligns with current Node.js architectural standards."

Tips & gotchas

This skill focuses on coding standards and patterns rather than specific library implementations; ensure you combine it with up-to-date documentation for the specific frameworks you are using. While it promotes general best practices, always verify compatibility with your specific runtime version (e.g., Node 18+ vs older LTS) as some conventions evolve rapidly.
