fastify介绍

fastify官网 NestJS支持2种底层的模式,1种是express,另外一种是fastifyexpress的优点是框架时间比较久,各种对应的方案和插件在网上都能找到资料,可以避免重复造轮子。fastify主要的优点就是高性能低开销,我喜欢快,所以决定接入fastify

接入

NestJS官网Fastify接入资料

  1. 首先安装依赖包
pnpm i --save @nestjs/platform-fastify
  1. 写适配器
import { NestFactory } from '@nestjs/core';
import {
  FastifyAdapter,
  NestFastifyApplication,
} from '@nestjs/platform-fastify';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    new FastifyAdapter()
  );
  await app.listen(3000);
}
bootstrap();
  1. 删除不要的依赖
pnpm uni @nestjs/platform-express @types/express

helloworld

然后我们用默认的路由来验证下配置是否成功。

npm start

> juejin-shenblog@0.0.1 start
> nest start
