Examples

Class

import React from 'react'
import { render } from 'react-jsbox'

// Create React Components:
class App extends React.PureComponent {
    constructor(props) {
        super(props)
        console.log(props)
        this.state = {
            count: 0
        }
    }

    render() {
        const { width, height } = this.props
        const styles = {
            container: $rect(0, 0, width, height),
            text: $rect(0, height * 0.25 - 15, width, 30),
            list: $rect(0, height * 0.5, width, 140)
        }
        return (
            <view frame={styles.container}>
                <label
                    frame={styles.text}
                    align={$align.center}
                    font={$font('ArialRoundedMTBold', 26)}
                    text={String(this.state.count)}
                    autoFontSize={true}
                />
                <list
                    frame={styles.list}
                    scrollEnabled={false}
                    data={['INCREASE', 'DECREASE', 'RESET']}
                    events={{
                        didSelect: (sender, { row }, data) =>
                            this.setState({
                                count: this.state.count + [1, -1, -this.state.count][row]
                            })
                    }}
                />
            </view>
        )
    }
}

// Create JSBox root container and render the React component into it
$ui.render({
    props: {
        title: '',
        debugging: true
    },
    views: [
        {
            type: 'view',
            props: {
                id: 'root'
            },
            layout(make, view) {
                make.edges.equalTo(view.super.safeArea)
            },
            events: {
                layoutSubviews(view) {
                    const { width, height } = view.frame
                    render(<App width={width} height={height} />, view)
                }
            }
        }
    ]
})

Use ref to access JSBox view instance

import React from 'react'
import { render } from 'react-jsbox'

        this._handleTextChange = this.handleTextChange.bind(this)
    }

    handleTextChange(sender) {
        this.setState({ text: sender.text })
    }

    componentDidMount() {
        this._input.current.focus()
    }

    render() {
        const { width, height } = this.props
        const styles = {
            container: $rect(0, 0, width, height - 40),
            text: $rect(0, 64, width, 30),

                    align={$align.center}
                    font={$font('ArialRoundedMTBold', 26)}
                    text={this.state.text || 'Hello World!'}

                    font={$font('ArialRoundedMTBold', 24)}
                    tintColor={$color('orange')}
                    placeholder={'Type here...'}
