It's using cofree-react-router for routing, the server is written using the hyper library.
In the frontend app the top most component rendered as:
createElement browserRouterClass {router, notFound: Nothing} []
where browserRouterClass comes from
cofree-react-router, on
the backend we can render the app using:
runRouter url router
since this is how browserRouterClass renders (with exception of routes that
where not found). This is fine for react since it compares the html content
(using a modified version of adler32,
if you wish to check the react code it is
here
).
The state is manged by
purescript-redox which
is similar to redux, but the dsl - interpreter pair is a free monad
paired with cofree comonad rather than redux actions with redux reducer.
