// proxy.ts
import { authMiddleware } from "@warpy-auth-sdk/core/next";
import { google } from "@warpy-auth-sdk/core";

const handler = authMiddleware({
  secret: process.env.AUTH_SECRET!,
  provider: google({
    clientId: process.env.GOOGLE_CLIENT_ID!,
    clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
    redirectUri: process.env.GOOGLE_REDIRECT_URI!,
  }),
  callbacks: {
    async user(u) {
      // Resolve/upsert your user
      return { id: u.id, email: u.email, name: u.name };
    }
  }
});

export function proxy(request: NextRequest) {
  const p = request.nextUrl.pathname;
  if (p.startsWith("/api/auth")) return handler(request);
  return NextResponse.next();
