When to use

Use this skill whenever you are dealing with Node.js code to obtain domain-specific knowledge for building robust, performant, and maintainable Node.js applications.

TypeScript with Type Stripping

When writing TypeScript for Node.js, use type stripping (Node.js 22.6+) instead of build tools like ts-node or tsx. Type stripping runs TypeScript directly by removing type annotations at runtime without transpilation.

Key requirements for type stripping compatibility:

• Use import type for type-only imports

• Use const objects instead of enums

• Avoid namespaces and parameter properties

• Use .ts extensions in imports

See rules/typescript.md for complete configuration and examples.
