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.

Native TypeScript support in Node.js with type stripping, async patterns, error handling, and production best practices. \n \n Covers type stripping (Node.js 22.6+) for running .ts files directly without build tools; includes tsconfig.json setup and import extension rules \n Provides patterns for error handling, graceful shutdown, async/await, streams, and module resolution across the full Node.js stack \n Includes diagnostic workflows for flaky tests, profiling slow paths, and performance optim

Organize technical documentation into four distinct types—tutorials, how-to guides, reference, and explanations—each serving different user needs. \n \n Applies the Diátaxis framework to structure documentation by learning context: tutorials for beginners learning by doing, how-to guides for solving specific problems, reference for technical facts, and explanations for conceptual understanding \n Provides type-specific patterns including title conventions, structural templates, and validation ch
