Firebase Auth UserCredential - refers to a value, but is being used as a type

Issue

I am using firebase, including auth, inside my React app with Typescript. So this is in a .tsx file

imported like import UserCredential from 'firebase/auth'

I am trying to apply the type UserCredential to my function argument, like this

const myCallback = (result: UserCredential) => { //function contents }

but I am getting the error "'UserCredential' refers to a value, but is being used as a type here"

However, when I inspect the type-definitions for UserCredential, it is defined as a type. How can it "refer to a value" but clearly be a type? I'd like to be able to use it to type my function argument for the intellisense and consistency, etc. I'm sure there is something I'm missing -so this issue will probably keep coming up unless I can figure out what is wrong. How can I make this work?

Solution

using firebase.User solved my problem

import firebase from 'firebase'

const myCallback = (result: firebase.User) => {
  // function contents
}

I hope it works for you
