You need to export four things:

1. loader - runs on any GET request, on the server. it accepts the Request and returns the props of your React compnent.
2. action- runs on the server on any non-GET, ie POST, PUT, DELETE, or <form>s submit
3. Component - your React component. it's initially server-rendered and then client-hydrated
4. default - you should mostly leave this line alone

This is framework is bleeding-edge. You'll need to read the code of the framework itself (it's very short) to understand what it's doing.
