How To Fix: Cannot Read Property 'GoogleAuthProvider' Of Undefined

I'm using firebase for authentication purposes but i'm having some troubles setting it up I already tried everything the tutorial said but to no success https://www.youtube.com/wat

Solution 1:

you are missing the auth script file

add this where you are loading firebase:

 <!-- firebase -->
  <script src="https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js"></script>
  <script src="https://www.gstatic.com/firebasejs/6.2.4/firebase-auth.js"></script>
  <!-- firebaseUI -->
  <script src="https://cdn.firebase.com/libs/firebaseui/4.0.0/firebaseui.js"></script>
