react-haskell: Haskell React bindings

This package provides high level bindings to Facebook's React library, meant for use with GHCJS.

React is a JavaScript library for building user interfaces. React (and React-Haskell) is focused on just UI - it's not a framework.

Currently React-Haskell can render simple stateful components, but not what React calls classes. Put another way, React-Haskell doesn't support lifecycle methods yet.

Here's a simple example which demonstrates basic elements, attributes, state, and handling events.

-- We're creating a class with JSString state
data Example
instance ReactKey Example where
    type ClassState Example = JSString
    type AnimationState Example = ()
    type Signal Example = JSString

-- updating to the new state without animation
transition :: JSString -> JSString -> (JSString, [AnimConfig Example])
transition oldState signal = (signal, [])

view :: JSString -> React Example ()
view str = div_ [ class_ "container" ] $ do
    input_ [ value_ str, onChange (Just . value . target) ]

main :: IO ()
main = withElem "id" $ \elem ->
    render elem =<< createClass view transition "" () []
