When to use

适用场景

Use this skill when you need to:

Develop backend applications using Fastify
Implement Fastify plugins and route handlers
Get guidance on Fastify architecture and patterns
Use TypeScript with Fastify (strip types)
Implement testing with Fastify's inject method
Configure validation, serialization, and error handling

在以下场景中可使用本技能：

使用Fastify开发后端应用
实现Fastify插件和路由处理器
获取Fastify架构与设计模式指导
在Fastify中结合TypeScript使用（剥离类型）
使用Fastify的inject方法实现测试
配置验证、序列化与错误处理

How to use

Core Principles

核心原则

Encapsulation: Fastify's plugin system provides automatic encapsulation
Schema-first: Define schemas for validation and serialization
Performance: Fastify is optimized for speed; use its features correctly
Async/await: All handlers and hooks support async functions
Minimal dependencies: Prefer Fastify's built-in features and official plugins

封装性：Fastify的插件系统提供自动封装机制
优先定义Schema：为验证和序列化定义Schema
性能优先：Fastify针对速度进行了优化；请正确使用其功能
Async/await：所有处理器和钩子均支持异步函数
最小依赖：优先使用Fastify的内置功能和官方插件
