#+TITLE: Purescript Halogen: Past, Present, and Future

Talk by John De Goes

[[https://github.com/slamdata/purescript-halogen][Halogen]] is a Purescript UI framework in the spirit of React (but doesn't wrap React) with the goal of expressing UIs in a declarative and type-safe way.

* FRP & React

FRP (in typed languages) typically needs "reactive" data types to be parameterized over the type of the things they "produce" so the FRP machinery can control how values of that type get passed around. In the more React-y style, events are supported somehow internally by the main UI data type (so don't need to be parameterized in that way).
