The singletons are only problematic if you need to interact with them asynchronously. `React.renderToString` is synchronous, so there's no reason stores have to be async.

Shameless plug: Fynx[0] is mostly synchronous, for example.

Fynx is what I'm using in my project. It'd be nice to get it added to the comparison.

but how would you deal with async data fetches then?

I want to have the same routing and data fetching logic both on the client and on the server, and for that I would need to have stores that are independent for different incoming HTTP requests.

I'm not sure how you're supposed to do it, but that hasn't been a problem for me. I set up two actions: load and init. load starts a request and init sets the data in the store.

Stores should be definitely sync in any implementation!
