Fastify (TypeScript) - Production Backend Framework
Overview
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.
Quick Start
Minimal server
✅ Correct: basic server with typed response
import Fastify from "fastify";
const app = Fastify({ logger: true });
app.get("/health", async () => ({ status: "ok" as const }));
