2025年来了，推荐6个Node.js服务端框架，可用于生产环境搭建

// 引入 express 模块
const express = require("express");
// 创建 express 应用
const app = express();
// 创建 HTTP 服务的端口
const port = 3000;
// 简单的中间件，用于记录请求信息
app.use((req, res, next) => {
  console.log(`${req.method} request for ${req.url}`);
  // 调用 next() 函数将控制权传递给下一个中间件或路由处理器
  next();
});
// 定义一个路由，响应 GET 请求
app.get("/", (req, res) => {
  res.send("Hello, Kelen.cc");
});
// 启动服务器
app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`);
});

// app.js
const Koa = require("koa");
const app = new Koa();
// 使用中间件
app.use(async (ctx) => {
  ctx.body = "Hello, Kelen.cc!";
});
// 监听端口
app.listen(3000, () => {
  console.log("Server is running on http://localhost:3000");
});

// src/app.controller.ts
import { Controller, Get } from "@nestjs/common";
@Controller()
export class AppController {
  @Get()
  getHello(): string {
    return "Hello, Kelen.cc";
  }
}

// src/app.module.ts
import { Module } from "@nestjs/common";
import { AppController } from "./app.controller";
@Module({
  imports: [],
  controllers: [AppController],
  providers: [],
})
export class AppModule {}

// src/main.ts
import { NestFactory } from "@nestjs/core";
import { AppModule } from "./app.module";
async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000); // 监听 3000 端口
}
bootstrap();

const Hapi = require("@hapi/hapi");
const Inert = require("@hapi/inert");
async function startServer() {
  const server = Hapi.server({
    port: 3000,
    host: "localhost",
  });
  // 注册 inert 插件
  await server.register(Inert);
  // 配置静态文件服务
  server.route({
    method: "GET",
    path: "/{param*}",
    handler: {
      directory: {
        path: "./public", // 指定静态文件目录
      },
    },
  });
  await server.start();
  console.log("Server running on %s", server.info.uri);
}
process.on("unhandledRejection", (err) => {
  console.error(err);
  process.exit(1);
});
startServer();

// Import the framework and instantiate it
import Fastify from "fastify";
const fastify = Fastify({
  logger: true,
});
// Declare a route
fastify.get("/", async function handler(request, reply) {
  return { hello: "world" };
});
// Run the server!
try {
  await fastify.listen({ port: 3000 });
} catch (err) {
  fastify.log.error(err);
  process.exit(1);
}
