What is the best way to use async/await inside onAuthStateChanged() of Firebase?

I'm using Firebase authentication with async/await in React Native. I'm looking for a better way to await inside firebase function. So my question is What is the best way to use async/await inside firebase.auth().onAuthStateChanged()?

Now, I implement it in this way. Create a async function inside onAuthStateChanged() and call itself. Like the example below... However, I think it looks weird.

firebase.auth().onAuthStateChanged(user => {

  const asyncFunc = async () => {

    await doSomething();

  }



  asyncFunc();

});

Is there any better way to implement it?

Thank you for your answer.

firebase.auth().onAuthStateChanged(async user => {

  const data = await getData();

  const action = await doSomething();

  // etc.

});





// also you can use

async function asyncHandler(user) {

    const data = await doSomething();

}



firebase.auth().onAuthStateChanged(asyncHandler);
