React Ape

The name is a "joke" based on Netflix's React Gibbon. I choose to use Ape then.

React Renderer to build UI interfaces using canvas/WebGL. React Ape was built to be an optional React-TV renderer. It's mainly a renderer focused on creating things for TV, PS4, Nintendo Switch, PS Vita, PS3 and low memory devices.

Under Development

1 - React Ape IS NOT Ready Yet.

2 - Should follow React Native Elements and Primitives. So will be easy to convert React Components (without bridges) to Canvas/WebGL.

3 - Accept Style as JavaScript Object.

4 - Allow to create React Components based on Canvas.

5 - Allow to inspect React Elements using React DevTools.

6 - I confess there's a lot of ideas and sketches in my head and I'll update the Readme when things become more clear.

Usage

React-ApeB

import React from 'react'
import { render, Text, ListView, View, Image, StyleSheet } from 'react-ape'

const styles = StyleSheet.create({
  heading: {
    top: 62,
    left: 250,
    color: 'white',
    fontFamily: 'Arial',
    fontWeight: 'bold',
    fontSize: 29,
  },
  date: {
    top: 62,
    left: 1150,
    color: 'red',
    fontFamily: 'Arial',
    fontWeight: 'bold',
    fontSize: 19,
  },
  logo: {
    top: 10,
    left: 30,
  },
  infoAboutRenderer: {
    top: 520,
    left: 45,
    fontFamily: 'Arial',
    fontWeight: 'bold',
    fontSize: 29,
  }
})

class App extends React.Component {
  constructor() {
    super()
    this.posters = [
      { name: 'Narcos', src: 'posters/narcos.jpg' },
      { name: 'Daredevil', src: 'posters/daredevil.jpg' },
      { name: 'Stranger Things', src: 'posters/stranger-things.jpg' },
    ]
    this.state = {
      date: new Date().toISOString()
    }
  }

  componentDidMount() {
    setInterval(() => this.setState({ date: new Date().toISOString() }), 1000)
  }

  renderPostersList() {
    const renderRow = (data, idx) => (
      <View key={idx} onClick={() => { console.log(data) }}>
        <Image src={data.src} width={200} height={300}/>
        <Text content={data.name}/>
      </View>
    )

    return (
      <ListView
        dataSource={this.posters}
        renderRow={renderRow}
      />
    )
  }

  render() {
    return (
      <View>
        <Image
          src={'posters/netflix.png'}
          style={styles.logo}
          width={210}
          height={100}
        />
        <Text style={styles.heading}>
          • Netflix Originals
        </Text>
        <Text style={styles.date}>
          {this.state.date}
        </Text>
        <Text style={styles.infoAboutRenderer}>
          Rendering with Canvas2DContext using React Ape
        </Text>
        { this.renderPostersList() }
      </View>
    )
  }
}

render(<App/>, document.getElementById('canvas-id'))

React Ape Components

React Ape provides a set of standard React components that abstract the underlying rendering implementation.

<View>

<ListView>

<Text>

Text is a flexible component that supports multi-line truncation, something which has historically been difficult and very expensive to do in DOM.

<Image>

Image is exactly what you think it is. However, it adds the ability to hide an image until it is fully loaded and optionally fade it in on load.
