The react-haskell package

[Tags:library, mit]

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.

 page_ :: ReactNode Void
 page_ =
     let cls = smartClass
             -- this is a record and these should really be curly braces,
             -- but haddock breaks on them.
             [ name = "page"

             -- initially the input is empty
             , initialState = ""

             -- always transition to the input's new value
             , transition = \(_, value) -> (value, Nothing)

             , renderFn = \_ str -> div_ [ class_ "container" ] $ do
                 input_ [ value_ str, onChange (Just . value . target) ]
             ]
     in classLeaf cls ()

 main :: IO ()
 main = do
     Just doc <- currentDocument
     Just elem <- documentGetElementById doc ("elem" :: JSString)
     render page_ elem
