React PIXI 🌈

release downloads

Write PIXI applications using React declarative style 👌

Install

npm install @inlet/react-pixi --save

ReactPixi has a few built-in components (like Container, Sprite, etc), but doesn't cover all pixi.js components. However, you can easily create new components with PixiComponent that is automatically picked up by React's reconciler:

import { Graphics } from 'pixi.js';
import { PixiComponent, Stage } from '@inlet/react-pixi';
const Rectangle = PixiComponent('Rectangle', {
  create: props => new Graphics(),
  applyProps: (instance, _, props) => {
    const { x, y, width, height, fill } = props;
    instance.clear();
    instance.beginFill(fill);
    instance.drawRect(x, y, width, height);
    instance.endFill();
  },
});
const App = () => (
  <Stage>
    <Rectangle x={100} y={100} width={500} height={300} fill={0xff0000} />
  </Stage>
);

() => {
  const reducer = (_, { data }) => data
  const Bunny = () => {
    const [motion, update] = useReducer(reducer)
    const iter = useRef(0)
    useTick(delta => {
      const i = (iter.current += 0.05 * delta)
      update({
        type: 'update',
        data: {
          x: Math.sin(i) * 100,
          y: Math.sin(i / 1.5) * 100,
          rotation: Math.sin(i) * Math.PI,
          anchor: Math.sin(i / 2),
        },
      })
    })
    return (
      <Sprite
