Vercel vs Cloudflare (Workers + Pages) 对比

// Vercel — Next.js 16 App Router，Cache Components（默认启用 PPR）+ 按需清除缓存
// next.config.ts
import type { NextConfig } from "next";

const nextConfig: NextConfig = {
  cacheComponents: true,
};

export default nextConfig;

// app/blog/[slug]/page.tsx — 使用 'use cache' + cacheTag 缓存数据
import { cacheTag } from "next/cache";

async function getPost(slug: string) {
  "use cache";
  cacheTag(`post-${slug}`);
  const res = await fetch(`https://api.example.com/posts/${slug}`);
  return res.json();
}

export default async function BlogPost({
  params,
}: {
  params: Promise<{ slug: string }>;
}) {
  const { slug } = await params;
  const post = await getPost(slug);

  return (
    <article>
      <h1>{post.title}</h1>
      <div dangerouslySetInnerHTML={{ __html: post.html }} />
    </article>
  );
}

// app/api/revalidate/route.ts — 按需清除缓存（Vercel Data Cache）
// "max" = stale-while-revalidate；若需在 webhook 中立即失效则使用 { expire: 0 }
import { revalidateTag } from "next/cache";
import { NextRequest, NextResponse } from "next/server";

export async function POST(req: NextRequest) {
  const { slug } = await req.json();
  revalidateTag(`post-${slug}`, "max");
  return NextResponse.json({ revalidated: true });
}

// vercel.json — 区域偏好与函数执行时长
{
  "regions": ["fra1"],
  "functions": {
    "app/api/revalidate/route.ts": { "maxDuration": 10 }
  }
}

// 部署
// $ vercel --prod

// Cloudflare — 将 Next.js 16 部署到 Workers（vinext，官方默认路径）
// 1）先评估兼容性，再添加到项目中（vinext init 会生成 Vite 配置）
// $ npx vinext check
// $ npx vinext init

// vite.config.ts — 路由级 ISR 使用 Workers Cache，数据缓存使用 KV
import { cloudflare } from "@cloudflare/vite-plugin";
import { cdnAdapter } from "@vinext/cloudflare/cache/cdn-adapter";
import { kvDataAdapter } from "@vinext/cloudflare/cache/kv-data-adapter";
import { defineConfig } from "vite";
import vinext from "vinext";

export default defineConfig({
  plugins: [
    vinext({
      // cdnAdapter 仅在 wrangler.jsonc 中设置 "cache": { "enabled": true } 时生效
      cache: { cdn: cdnAdapter(), data: kvDataAdapter() },
    }),
    cloudflare({
      viteEnvironment: { name: "rsc", childEnvironments: ["ssr"] },
    }),
  ],
});

// 部署 — 会自动生成 Worker 配置
// $ npx @vinext/cloudflare deploy

// 另一种方式：OpenNext 适配器 — open-next.config.ts
import { defineCloudflareConfig } from "@opennextjs/cloudflare";
import r2IncrementalCache from "@opennextjs/cloudflare/overrides/incremental-cache/r2-incremental-cache";

export default defineCloudflareConfig({ incrementalCache: r2IncrementalCache });
// $ opennextjs-cloudflare build && opennextjs-cloudflare deploy

// Access for Workers — 将 Worker 绑定到 Access 应用
// POST /accounts/{account_id}/access/apps
// "destinations": [{ "type": "worker", "worker_id": "<worker-id>" }]
