Canvas UI is a general UI renderer runs on HTML Canvas. https://alibaba.github.io/canvas-ui/

---

It provides a series of React components, allowing developers to quickly build Canvas-based applications using their existing knowledge.

It also features a DOM-like scene tree, enabling developers to manipulate elements drawn in Canvas just like they would manipulate DOM elements.

import React from 'react'
import { Canvas, Text, Flex } from '@canvas-ui/react'

export default () => {
  const containerStyle = {
    width: 250,
    flexDirection: 'column'
  }
  const textStyle = {
    maxWidth: containerStyle.width,
    maxLines: 1,
  }
  return (
    <div style={{ height: '100px' }}>
      <Canvas>
        <Flex style={ containerStyle }>
          <Text style={ textStyle }>我能吞下玻璃而不伤身体。</Text>
          <Text style={ textStyle }>私はガラスを食べられます。それは私を傷つけません。</Text>
          <Text style={ textStyle }>The quick brown fox jumps over the lazy dog.</Text>
        </Flex>
      </Canvas>
    </div>
  )
}
