Add provider dynamic import example

[albertpurnama]

Your ENS/address: apurn.eth

I moved Provider away from _app.tsx to demonstrate how to dynamically load wagmi's Provider.

This serves as an answer for #32.

Improvements

Before:

First Load JS >300kb across all pages

After:

First load JS on heaviest page (the one where we import wagmi without any lazy loading) = 200kb
Shared JS (~70kb) because we dynamically loaded wagmi AND ethers

Thanks for doing this! Let's keep the example in GitHub Discussions for now.

Thanks to this issue i could solve my problem with a similiar approach.
Probably there have been some changes to NextJS and Wagmi.
I will post it as reference for future use.

// components/WagmiProvider.tsx

import { ReactNode } from 'react';
import { createClient, WagmiConfig } from 'wagmi';

import { getDefaultProvider } from 'ethers';

const client = createClient({
  autoConnect: true,
  provider: getDefaultProvider(),
});

const WagmiProvider = ({ children }: { children: ReactNode }) => {
  return <WagmiConfig client={client}>{children}</WagmiConfig>;
};

export default WagmiProvider;

// _app.tsx

import type { AppProps } from 'next/app';
import dynamic from 'next/dynamic';

const WagmiProvider = dynamic(() => import('components/WagmiProvider'));

const App = ({ Component, pageProps }: AppProps) => {
  return (
    <>
      <WagmiProvider>
        <Component {...pageProps} />
      </WagmiProvider>
    </>
  );
};

export default App;

@LaCocoRoco, it seems your solution doesn't actually cause the WagmiProvider to be dynamically imported. Perhaps it's due to the reasons mentioned in #32.
