google auth and firebase persistence-CodePudding

heres my log in function, it works it logs you in via google account, but on refresh it does not stay logged in. what am I doing wrong? sorry I have no idea how to format the code to show correctly here.

const provider = new GoogleAuthProvider();


const  login = () => 
{setPersistence(auth, browserSessionPersistence)
    .then(()=> {
        signInWithPopup(auth, provider)
    .then((result) => {

        const credential = GoogleAuthProvider.credentialFromResult(result);
        const token = credential?.accessToken;
        // The signed-in user info.
        const user = result.user;
        //console.log({ credentials, token,  user });
       
        
    })
    .then(() => {
      setSignIn(true);
      
    })
    .catch((error) => {
        // Handle Errors here.
        const errorCode = error.code;
        const errorMessage = error.message;
        // The email of the user's account used.
        const email = error.email;
        // The AuthCredential type that was used.
        const credential = GoogleAuthProvider.credentialFromError(error);
        //console.log({ errorCode, errorMessage, email, credential });
    });

})

};

CodePudding user response：

Firebase automatically restores the user credentials when you restart the app, but your code only responds to the explicit sign in (signInWithPopup).

To pick up the automatic restore (and other changes in authentication state), you should use an auth state listener as shown in the first code sample in the documentation on getting the current user:

firebase.auth().onAuthStateChanged((user) => {
  if (user) {
    // User is signed in, see docs for a list of available properties
    // https://firebase.google.com/docs/reference/js/firebase.User
    var uid = user.uid;
    // ...
  } else {
    // User is signed out
    // ...
  }
});

Since v9, the code has changed.

import { getAuth, onAuthStateChanged } from "firebase/auth";

const auth = getAuth();
onAuthStateChanged(auth, (user) => {
  if (user) {
    // User is signed in, see docs for a list of available properties
    // https://firebase.google.com/docs/reference/js/firebase.User
    const uid = user.uid;
    // ...
  } else {
    // User is signed out
    // ...
  }
});
