3-1:将fastify应用在NestJS中1.安装包执行命令pnpm add @nestjs/platform-fa

1.安装包

执行命令pnpm add @nestjs/platform-fastify

2.修改创建方式

修改main.ts

import {
  FastifyAdapter,
  NestFastifyApplication,
} from '@nestjs/platform-fastify';
//express version
//const app = await NestFactory.create(AppModule);

//fastify version
const app = await NestFactory.create<NestFastifyApplication>(
AppModule,
new FastifyAdapter(),
  );

这样就简单的将原本的基于express的版本迁移到了fastify
