// detect provider using @metamask/detect-provider
detectEthereumProvider().then((provider) => {
  if (provider && provider.isMetaMask) {
    provider.on('accountsChanged', handleAccountsChanged);
    // connect btn is initially disabled
    $('#connect-btn').addEventListener('click', connect);
    checkConnection();
  } else {
    console.log('Please install MetaMask!');
  }
});

function connect() {
  ethereum
    .request({ method: 'eth_requestAccounts' })
    .then(handleAccountsChanged)
    .catch((err) => {
      if (err.code === 4001) {
        console.log('Please connect to MetaMask.');
      } else {
        console.error(err);
      }
    });
}

function checkConnection() {
  ethereum.request({ method: 'eth_accounts' }).then(handleAccountsChanged).catch(console.error);
}

function handleAccountsChanged(accounts) {
  console.log(accounts);

  if (accounts.length === 0) {
    $('#connection-status').innerText = "You're not connected to MetaMask";
    $('#connect-btn').disabled = false;
  } else if (accounts[0] !== currentAccount) {
    currentAccount = accounts[0];
    $('#connection-status').innerText = `Address: ${currentAccount}`;
    $('#connect-btn').disabled = true;
  }
}
