Is this Firebase Context correct?

I got this code online but not sure about it. Will the values come to me reactively. I'm worried that if I have a few protected(authenticated) routes, and firebase auth is still loading, then my user will get redirected to login page.

import { JSXElement, createContext, useContext } from "solid-js";
import { createStore } from "solid-js/store";
import { app } from "../configs/firebase";
import { Auth, getAuth, onAuthStateChanged, User } from "firebase/auth";

interface UserStore {
  currentUser: User | null;
  loading: boolean;
}

interface FirebaseStore {
  user: UserStore;
  auth: Auth;
}

const FirebaseContext = createContext<FirebaseStore>();

export const FirebaseProvider = (props: { children: JSXElement }) => {
  const [user, setUser] = createStore<UserStore>({
    currentUser: null,
    loading: true,
  });

  const auth = getAuth(app);
  onAuthStateChanged(auth, (currentUser) => {
    setUser("currentUser", currentUser);
    setUser("loading", false);
  });

  const store = {
    user,
    auth,
  };

  return (
    <FirebaseContext.Provider value={store}>
      {props.children}
    </FirebaseContext.Provider>
  );
};

export function useFirebase(): FirebaseStore {
  return useContext(FirebaseContext)!;
  // Non-null assertion as we'll always provide the context via FirebaseProvider
}

import { JSXElement, createContext, useContext } from "solid-js";
import { createStore } from "solid-js/store";
import { app } from "../configs/firebase";
import { Auth, getAuth, onAuthStateChanged, User } from "firebase/auth";

interface UserStore {
  currentUser: User | null;
  loading: boolean;
}

interface FirebaseStore {
  user: UserStore;
  auth: Auth;
}

const FirebaseContext = createContext<FirebaseStore>();

export const FirebaseProvider = (props: { children: JSXElement }) => {
  const [user, setUser] = createStore<UserStore>({
    currentUser: null,
    loading: true,
  });

  const auth = getAuth(app);
  onAuthStateChanged(auth, (currentUser) => {
    setUser("currentUser", currentUser);
    setUser("loading", false);
  });

  const store = {
    user,
    auth,
  };

  return (
    <FirebaseContext.Provider value={store}>
      {props.children}
    </FirebaseContext.Provider>
  );
};

export function useFirebase(): FirebaseStore {
  return useContext(FirebaseContext)!;
  // Non-null assertion as we'll always provide the context via FirebaseProvider
}

Looks good, I’d suggest only calling setUser once and passing in both values rather than separately
