custu, loading next js

Step 1: Install Next.js

npx create-next-app my-next-app
cd my-next-app

Step 2: Create a custom loader component (e.g., CustomLoader.js)

// CustomLoader.js
import React from 'react';

const CustomLoader = () => {
  return (
    <div>
      Loading...
    </div>
  );
};

export default CustomLoader;

Step 3: Implement dynamic loading using the custom loader

// pages/_app.js
import { AppProps } from 'next/app';
import CustomLoader from '../path/to/CustomLoader';

function MyApp({ Component, pageProps }: AppProps) {
  return (
    <React.Suspense fallback={<CustomLoader />}>
      <Component {...pageProps} />
    </React.Suspense>
  );
}

export default MyApp;

Step 4: Use dynamic imports for components/pages

// pages/index.js
import dynamic from 'next/dynamic';

const DynamicComponent = dynamic(() => import('../path/to/DynamicComponent'), {
  loading: () => <CustomLoader />,
});

const HomePage = () => {
  return (
    <div>
      <h1>Welcome to Next.js!</h1>
      <DynamicComponent />
    </div>
  );
};

export default HomePage;

Step 5: Run the Next.js app

npm run dev

Note: Replace '../path/to/DynamicComponent' with the actual path to your dynamic component.
