如何减少vercel无服务器函数的包大小?
我一直在nx monorepo中摆弄next-auth和nextjs app dir,但在使用电子邮件提供商auth部署应用程序时,我遇到了瓶颈。由于某些原因,依赖项的大小会膨胀并超过限制。

我尝试使用vercel.json来排除最大的违规者,但它不起作用。

// apps/my-app/vercel.json
{
  "functions": {
    "app/api/auth/[...nextauth].js": {
      "excludeFiles": "**/node_modules/{@swc,@esbuild}/**"
    }
  }
}

nextauth中的代码基本上遵循文档:

// apps/my-app/app/api/auth/[...nextauth]/route.ts

import NextAuth from 'next-auth';
import { PrismaAdapter } from '@next-auth/prisma-adapter';
import { PrismaClient } from '@prisma/client';
import EmailProvider from 'next-auth/providers/email';

const emailProvider = EmailProvider({
  from: 'no-reply@exanubes.com',
  type: 'email',
  server: {
    host: process.env.EMAIL_SERVER_HOST,
    port: process.env.EMAIL_SERVER_PORT,
    maxAge: 24 * 60 * 60, // 24 hours
    auth: {
      user: process.env.EMAIL_SERVER_USER,
      pass: process.env.EMAIL_SERVER_PASSWORD,
    },
  },
});

const prisma = new PrismaClient();

const handler = NextAuth({
  secret: process.env.NEXTAUTH_SECRET,
  session: {
    strategy: 'jwt',
  },
  adapter: PrismaAdapter(prisma),
  providers: [emailProvider],
});

export { handler as GET, handler as POST };

我能够通过删除锁定文件并将所有依赖项移动到devDependencies来修复此问题。有趣的是,在vercel部署日志中,它注意到swc linux dep丢失了,但没有它们也编译得很好。

- info Downloading WASM swc package...
- warn Found lockfile missing swc dependencies, run next locally to automatically patch
- info Using wasm build of next-swc
