import { NextResponse, NextRequest } from "next/server";

export async function GET(request: NextRequest) => {
  // Set up CORS for this API route
  await setupCors(request, NextResponse.next, {
    // Define your CORS configuration options here
    origin: 'https://example.com', // origin or *
    methods: ['GET', 'POST'],
    allowedHeaders: ['Authorization'],
  });

  // Handle your API route logic here
  // ...

  // Return your API response
