如何使用TypeScript将对象注入到Fastify的路由方法中？

npm install fastify typescript

import fastify, { FastifyInstance, RouteHandlerMethod } from 'fastify';

// 创建Fastify实例
const app: FastifyInstance = fastify({ logger: true });

// 定义要注入的对象
const myObject = {
  name: 'My Object',
  description: 'This is my injected object',
};

// 创建路由处理方法
const myRouteHandler: RouteHandlerMethod = async (request, reply) => {
  // 在路由方法中使用注入的对象
  reply.send(myObject);
};

// 注册路由
app.get('/', myRouteHandler);

// 启动服务器
const start = async () => {
  try {
    await app.listen(3000);
    app.log.info('Server started');
  } catch (err) {
    app.log.error(err);
    process.exit(1);
  }
};

start();

npx tsc app.ts

node app.js
