ok, i was trying to do this for production. I am switching over to firebase but it's not working well with my client-server-architecture

Ah I see, most frontend frameworks have libraries that work with firebase auth. If you use an MVC like rails or .NET core MVC etc, you can use Firebase auth from a CDN and put it in script tags along with JS to work with the library.
