Have three states: nil, :log-in-success, :log-in-failure

don't render anything when the state is nil, and set it to one of those two values when you know what's going on

okay, but where should the render be then? get-login-state is an ajax call and its sets the login atom, should the render be in the handler then?

render immediately on startup - but render an empty div or a spinner or whatever works for your app

that's what people do usually in React, or Reagent

i am still not getting a desired result, it still renders the login ui instead of main even if login is set to true
