Keep web3auth session persistent after page refresh

Help - Plug n Play Web - Modal SDK
1

Hello everyone! I am trying to use make the web3auth session persistent even after the page refresh. I was hope that wagmi autoConnect: true will work, but no. Also I thought, that data, stored in localStorage will be used by wagmi and web3auth to restore connection.

In reality, every time when I refresh the page, it loses the session and I have to reconnect manually. Please, help me to understand how to make it work

Same problem, is there any solution?

Here is the solution that solved my problem:

import { ReactNode, useEffect } from "react";
import { useAccount, useConnect } from "wagmi";

export const EagerConnectionWrapper = ({
  children,
}: {
  children: ReactNode;
}) => {
  const { connect, connectors, pendingConnector } = useConnect();
  const { isDisconnected } = useAccount();

  useEffect(() => {
    if (!isDisconnected) return;

    // if wagmi.connected set to true, then wagmi will not show modal
    // to reconnect user wallet, but instead will use prev connection
    // I found this example in this public repo: https://github.com/sumicet/web3auth-modal-wagmi
    const wagmiConnected = localStorage.getItem("wagmi.connected");
    const isWagmiConnected = wagmiConnected
      ? JSON.parse(wagmiConnected)
      : false;

    if (!isWagmiConnected) return;
    connect({ connector: connectors[0] });
  }, [connect, connectors]);

  return <>{children}</>;
};

In the project root wrap your code in that component

const App = () => {
  return (
    <WagmiConfig client={wagmiClient}>
      <EagerConnectionWrapper>
        { /* your code */ }
      </EagerConnectionWrapper>
    </WagmiConfig>
  );
};
