Using Firebase with ReactJS

Is it me or is this mixin is storing entirely the wrong thing?

If I remember correctly, state is the transient component-local stuff e.g. what a user currently has typed in a field, or whether a pane is open or closed. While you can certainly persist it locally (so the user sees the same thing when he reopens the site/application), it seems odd to persist it remotely and not persist props (the application state).

Now I understand that the homepage demo uses state, so demoing based on that is fair enough, but building a mixin to remotely persist state?
