React Leaflet + React Pixi

Write Leaflet and PixiJS applications using React declarative style.

Demo usage:

function App() {
  return (
    <MapContainer center={[51.505, -0.09]} zoom={13} style={{width: '100vw', height: '100vh'}}>
      <TileLayer
        attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
      />
      <PixiRoot>
        <MyContent />
      </PixiRoot>
    </MapContainer>
  )
}

function MyContent() {
  const [containerX, containerY] = useProject([51.5, -0.09])
  const [markerOffset, setMarkerOffset] = useState(0)
  const [markerX, markerY] = useProject([51.5, -0.09 + markerOffset], [containerX, containerY])
  const scale = useScale()

  const [direction, setDirection] = useState(1)
  useTick(delta => {
    setMarkerOffset(val => val + delta * direction / 3000)
    if (markerOffset > 0.05) {
      setDirection(-1)
    } else if (markerOffset < -0.05) {
      setDirection(1)
    }
  })

  return (
    <Container x={containerX} y={containerY}>
      <Sprite x={markerX} y={markerY} anchor={0.5} scale={1 / scale} image="https://s3-us-west-2.amazonaws.com/s.cdpn.io/693612/IaUrttj.png" />
    </Container>
  )
}

The work is based on React Leaflet, React Pixi and Leaflet.PixiOverlay. This project is to combine them all together, provide a natural declarative code style, and fully encapsulate Leaflet.PixiOverlay inside.

The code is quite simple. You just need to copy PixiRoot.js and hooks.js in your project. Feel free to modify them as your need.(and don't forget to leave a ⭐star : )
