Node.js Backend
Verify before implementing: For framework-specific APIs (Express 5, Fastify 5, Node.js 22+ built-ins), search current docs via search_docs before writing code. Training data may lag current releases.
Framework Selection
| Context | Choose | Why |
|---|---|---|
| Edge/Serverless | Hono | Zero-dep, fastest cold starts |
| Performance API | Fastify | 2-3x faster than Express, built-in schema validation |
| Enterprise/team | NestJS | DI, decorators, structured conventions |
| Legacy/ecosystem | Express | Most middleware, widest adoption |
Ask user: deployment target, cold start needs, team experience, existing codebase.
