I'm trying to set up a spinner, when the auth is changed. I've tried using the following method. (If spinner is true, it replaces the whole router component)
function App() {
const [currentUser, setCurrentUser] = useState(false);
const [spinner, setSpinner] = useState(false);
useEffect(() => {
setSpinner(true);
onAuthStateChanged(auth, (user) => {
if (user) {
setCurrentUser(user);
setSpinner(false);
} else {
setCurrentUser(false);
}
});
}, []);
return (
<Context.Provider value={{ db, auth, currentUser, setSpinner }}>
{spinner? (
<Spinner />
) : (
<BrowserRouter>
<Navbar></Navbar>
<Routes>
<Route
path='/'
element={currentUser ? <MessageCenter /> : <Landing />}
/>
</Routes>
</BrowserRouter>
)}
</Context.Provider>
);
}
export default App;
The problem I am facing here is, that on the first reload, the spinner doesn't show up but if I reload my page again, the spinner shows (as it is placed in use effect, in app.js) the onAuthStateChanged is supposed to be called each time the application is loaded (To set the currentUser, On logout or login) so for that, I'm using it in useEffect on the app.js.
Is there a way to show spinner while waiting for onAuthStateChanged?
