Thank you, i made use of the enabled property, and used refectch() in the component. I’m going to export it into. Custom hook and rejig it. This is the pattern I came up with. I want to call my route when a button is clicked and have access to isLoading, onError etc… I have implemented a pattern using ‘’refetch()’’ but it doesn’t feel ‘correct’ is there a better way of doing this. I will also create a custom hook out of it. ‘’’js const { refetch } = trpc.authDomain.signIn.useQuery( { email: userEmail }, { enabled: false, onError: (e: any) => { console.log('there was an error with the endpoint'); }, } ); async function isEmailVerified() { const response = await refetch(); const verification = response.data; // i want to access isLoading directly without writing many lines of new code which i would have to with this current approach if (verification?.status === 'tryAgain') { console.log('email not verified'); setHasInitiatedSignIn(true); } if (verification?.status === 'ok') { console.log('user can now verify code sent to their email address'); setHasInitiatedSignIn(true); } } Return <button onClick={isEmailVerified}/> ‘’’

to me signIn is a mutation - not a query.

const MySignInComp = () => {
  const { mutate: signIn, isLoading: isSigningIn } = trpc.auth.signin.useMutation({
  onSuccess() {
    // do something on successful mutation
  },
});

 return (
    <button onClick={signIn}>
      {isSigningIn && <Spinner />}
      Sign In
    </button>
  );
};

const MySignInComp = () => {
  const { mutate: signIn, isLoading: isSigningIn } = trpc.auth.signin.useMutation({
  onSuccess() {
    // do something on successful mutation
  },
});

 return (
    <button onClick={signIn}>
      {isSigningIn && <Spinner />}
      Sign In
    </button>
  );
};

How would you handle ‘isLoading’

julius•2y ago

isLoading prop on the useMutation (updated code snippet)

Ill try this approach, thanks

You’ll find it much easier than fighting useQuery I reckon 😉
