/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  async redirects() {
    return [
        source: '/page2',
        destination: '/blog/page2',
        permanent: true,

module.exports = nextConfig

Next, let's create page2 as below

Create page2.js under pages

export default function Page2(){

    return (<div>Hello 2</div>)
