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.
- 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.git Here 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 as R -- The props for the component type ExampleProps = { label :: String } -- The internal state of the component type ExampleState = { counter :: Int } -- Create a component by passing a record to the `react` function. -- The `render` function takes the props and current state, as well as a -- state update callback, and produces a document. example :: R.ReactComponent ExampleProps example = R.react { initialState: { counter: 0 } , receiveProps: \_ _ _ -> pure unit , render: \{ label } { counter } setState -> R.button { onClick: mkEffFn1 \_ -> do setState { counter: counter + 1 } } [ 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' /> );
