现代前端开发趋势：React 18、Server Components 与 AI 辅助

2. Server Components

利用服务器组件减少客户端负载。

// app/page.jsx
import { Suspense } from 'react';
import UserList from './components/UserList';

export default function Page() {
  return (
    <div>
      <h1>Users</h1>
      <Suspense fallback={<div>Loading users...</div>}>
        <UserList />
      </Suspense>
    </div>
  );
}

// components/UserList.jsx
async function fetchUsers() {
  const response = await fetch('https://api.example.com/users');
  return response.json();
}

export default async function UserList() {
  const users = await fetchUsers();
  return (
    <ul>
      {users.map(user => (
        <li key={user.id}>{user.name}</li>
      ))}
    </ul>
  );
}

3. Edge Computing

边缘计算可提升响应速度。

// api/hello.js (Vercel Edge Functions)
import { NextRequest, NextResponse } from 'next/server';

export const config = { runtime: 'edge' };

export default function handler(req) {
  return new NextResponse(`Hello from Edge Function!`);
}

// worker.js (Cloudflare Workers)
addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
  return new Response('Hello from Cloudflare Worker!');
}

4. AI 辅助开发

利用 AI 工具优化代码效率。

// 示例：使用 AI 生成的代码
function calculateFactorial(n) {
  if (n <= 1) return 1;
  return n * calculateFactorial(n - 1);
}

// 示例：使用 AI 优化的代码
function calculateFactorialOptimized(n) {
  let result = 1;
  for (let i = 2; i <= n; i++) {
    result *= i;
  }
  return result;
}
