SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers often juggle multiple JavaScript runtimes (Node.js, Bun, Deno) and ecosystems, requiring disparate tooling and patterns. This Skill provides a unified set of guidance for cross-runtime development, helping teams align on best practices, templates, and integration points.

Core Features & Use Cases

  • Cross-runtime guidance for ES2024/ES2025 features and modern tooling (Vitest, ESLint, Biome).
  • Starter templates and patterns for Express, Fastify, and Hono across Node.js, Bun, and Deno.
  • Quick-start workflows to bootstrap projects and migrate between runtimes.

Quick Start

Load this skill and request a starter project scaffold for a chosen runtime (Node.js 22, Bun, or Deno). For example: "Create a minimal Express API scaffold for Node.js 22 using this skill."
