koa

When to use this skill

Use this skill whenever the user wants to:

• Build Node.js HTTP services with Koa and its onion-model middleware
• Configure routing (koa-router), body parsing, error handling, and static files
• Compose async middleware with ctx and next patterns
• Create lightweight REST APIs or web applications

How to use this skill

Workflow

1. Create app — instantiate Koa and add middleware in order
2. Add routing — use @koa/router for route definitions
3. Handle errors — add error middleware at the top of the stack
4. Deploy — run behind reverse proxy with HTTPS
