About this skill
Fastify is a high-performance Node.js web framework built around JSON schema validation, encapsulated plugins, and great developer ergonomics. In TypeScript, pair Fastify with a type provider (Zod or TypeBox) to keep runtime validation and static types aligned. ✅ Correct: basic server with typed response ❌ Wrong: start server without awaiting listen Fastify validates requests/responses via JSON schema. Use a type provider to avoid duplicating types. ✅ Correct: Zod schema drives validation + types ✅ Correct: TypeBox schema Use plugins to keep concerns isolated and testable (auth, db, routes). ✅ Correct: route plugin ✅ Correct: register with a prefix Centralize unexpected failures and return stable error shapes. ✅ Correct: setErrorHandler Add standard security plugins and enforce payload limits. ✅ Correct: Helmet + CORS + rate limiting Close HTTP server and downstream clients (DB, queues) on SIGINT/SIGTERM. ✅ Correct: close on signals Test routes in-memory without binding ports. ✅ Correct: inject request - Prefer Fastify for schema-based validation, predictable plugins, and high throughput. - Prefer Express for minimal middleware and maximal ecosystem familiarity. - Prefer Zod for app codebases that already standardize on Zod (forms, tRPC, shared types). - Prefer TypeBox for OpenAPI generation and performance-critical validation. - Skip request validation; validate at boundaries...
