Interoperate with React

**React is used by Pux merely as a renderer. Any React component interoperation is not recommended or supported by the library.**

Using Pux components in React

Pux components can be rendered to a React class instead of the DOM for use inside an existing React application.

Use start to initialize your component with state, then use renderToReact to return a React class.

module FancyComponent where

-- State, Event, foldp, view functions...

toReact :: ∀ props. State -> Effect (ReactClass props)
toReact state = do
  app <- start
    { initialState: state
    , view
    , foldp
    , inputs: []

  renderToReact app.markup app.input

After your PureScript has been compiled, call this module's toReact method to return your class:

const FancyComponent = PS.FancyComponent.toReact(state)()

Using React components in Pux

Expose your React component by creating a .js and .purs file of the same name, and using the PureScript FFI to bind them:

const React = require('react')

exports.fancyComponent = React.createClass(..)

In your PureScript code, add a foreign module definition for the fancyComponent, and use the reactClass function to create an HTML element constructor which you can use in your views.

-- | src/FancyComponent.purs

module FancyComponent where

import React (ReactClass)

foreign import fancyClass :: ∀ props. ReactClass props

fancy :: ∀ ev. HTML ev -> HTML ev
fancy = reactClass fancyClass "fancy"

You can then use fancy in your views:

view count =
    button #! onClick (const Increment) $ text "Increment"
    fancy $ text ("Fancy " <> (show count))
    button #! onClick (const Decrement) $ text "Decrement"

To pass arbitrary props to a react class use reactClassWithProps.
