I really like the Om/Omniscient model of using immutable data to represent application state - deciding whether or not to rerender a component and all of its subcomponents only requires comparing a hash.

However, for the app I'm working on, I want most the single source of truth for most application state to be on the server. I'm passing data from server to client in JSON. Has anybody come up with a good way to serialize/deserialize immutable objects? I might try out transit-js, but I'm wondering if anybody has already gotten this working?
