purescript-halogen-cf

A library for writing comonadic renderers with Halogen.

Structure

The library is comprised of two modules:

• Halogen.Cf: core library.
• Halogen.Cf.Sugar: one-liners for stuff that I found myself writing over and over.

Basic example

myComponent = HCf.component HCf.defaultOptions
  ({ count: 0 } # fixCf2 \render { count } _ -> do

    pure $
      HH.button
        [ HE.onClick \_ -> HCf.doThis render ({ count: count + 1 }) ]
        [ HH.text $ show count ])

Example

Check out the ./example. A live version is here.
