This package implements an opinionated set of bindings to the React library, optimizing for the most basic use cases.
- All React DOM elements and attributes are supported (soon, events are a work in progress).
- An intuitive API for specifying props - no arrays of key value pairs, just records.
- Attributes are optional, but type-checked. It is a type error to specify
hrefas an integer, for example.
You can install this package using Bower:
bower install git@github.com:lumihq/purescript-react-basic.gitHere is an example component which renders a label read from props along with a counter:
module React.Basic.Example where import Prelude import Control.Monad.Eff.Uncurried (mkEffFn1) import React.Basic (ReactComponent, react) import React.Basic.DOM as R -- The props for the component type ExampleProps = { label :: String } -- Create a component by passing a record to the `react` function. -- The `render` function takes a display name, the props and current state, as well as a -- state update callback, and produces a document. example :: ReactComponent ExampleProps example = react { displayName: "Example" , initialState: { counter: 0 } , receiveProps: \_ _ _ -> pure unit , render: \{ label } { counter } setState -> R.button { onClick: mkEffFn1 \_ -> do setState \s -> { counter: s.counter + 1 } , children: [ R.text (label <> ": " <> show counter) ] } }This component can be used directly from JavaScript. For example, if you are using purs-loader:
import {example as Example} from 'React.Basic.Example.purs'; const myComponent = () => ( <Example label='Increment' /> );
