Fastify REST API

Overview

Fastify is a high-performance web framework for Node.js with low overhead and built-in schema validation. This skill should be invoked when creating performant REST APIs that require high throughput, low latency, or strong type safety through schema validation.

Core Principles

• Schema First: Define JSON schemas for validation and serialization
• Plugin System: Extend functionality through plugins
• Performance: Built for speed with minimal overhead
• Type Safety: Full TypeScript support with type inference

Preparation Checklist

• Initialize project: npm init fastify
• Choose TypeScript or JavaScript
• Plan route structure and schemas
• Select required plugins
