Effects, coeffects & subscriptions: a pit of success for SPAs

This is an extended version of my SCBCN17 talk: "Native/Browser SPA versions using ClojureScript and re-frame".
We'lI talk mainly about the advantages of using re-frame’s effects and coeffects, re-frame’s subscriptions and modelling a UI as FSMs, which we have been learning lately while working on the mobile and browser versions of a SPA using ClojureScript and re-frame.
