SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you avoid common Node.js mistakes by turning best practices into clear decision-making criteria for real projects.

Core Features & Use Cases

  • Framework and runtime selection: Pick tools (Hono/Fastify/Express, ESM/CJS, Node/Bun/Deno) based on deployment target, team familiarity, and performance needs.
  • Architecture and layering guidance: Apply a controller/service/repository structure to improve testability and maintainability as projects grow.
  • Operational safety in development: Choose practical patterns for error handling, async concurrency, validation at boundaries, and security mindset checklists.
  • Testing strategy planning: Select unit, integration, and E2E approaches and prioritize what to test for fast, reliable outcomes.

Use case example: You are planning a production API and need to decide the framework, module system, error strategy, validation points, and async approach without copying a random template—use this Skill to produce a justified plan aligned to your constraints.

Quick Start

Ask the skill to help you choose the Node.js framework, module system, async pattern, and error-handling strategy for your API given your deployment target and performance needs.
