Ejemplo
const { canvasRef, renderFpsRef } = useAnimatedCanvas({
fps: 100,
draw: (ctx, w, h) => {
// Dibujar lo que sea a 100fps
ctx.fillStyle = '#3b82f6'
ctx.fillRect(0, 0, w * Math.random(), h)
},
})
return <canvas ref={canvasRef} style={{ width: '100%', height: 300 }} />
Notas
- DPR automático: escala el canvas al devicePixelRatio de la pantalla
- Resize automático: detecta cambios de tamaño via getBoundingClientRect
- Throttle configurable: rAF corre a ~144fps nativo, el hook filtra a N fps
- FPS real:
renderFpsRef.currenttiene los FPS medidos (no el target) - drawRef pattern: actualiza el callback sin re-crear el loop de animación
