Popmotion carousel fix for new version

Question

This is not working for some reason.

https://popmotion.io/pure/ as mentioned here it has to be

const slider = document.querySelector('.slider');
const sliderX = value(0, styler(slider).set('x'))

listen(slider, 'mousedown touchstart').start(() => {
  pointer({ x: sliderX.get() })
    .pipe(({ x }) => x, clampMovement)
    .start(sliderX);
});

listen(document, 'mouseup touchend').start(() => {
  decay({
    from: sliderX.get(),
    velocity: sliderX.getVelocity()
  }).pipe(clampMovement)
    .start(sliderX);
});

whenever I use it clamp movement is showing as undefined. What should it be actually? Any may to make that working?

If you look at the Decay documentation you'll see:

Note: This animation is deprecated in favour of inertia.

The documentation of inertia animation: https://popmotion.io/api/inertia/

A codepen: https://codepen.io/popmotion/pen/BMNvqj

And this is a live example:

const { styler, inertia, listen, pointer, value, calc } = window.popmotion;

const slider = document.querySelector('.carousel');

const divStyler = styler(slider);
const sliderX = value(0, v => divStyler.set('x', v));

listen(slider, 'mousedown touchstart').start(() => {

  pointer({ x: sliderX.get() })
    .pipe(({ x }) => x)
    .start(sliderX);
});

listen(document, 'mouseup touchend').start(() => {
  inertia({
    min: -slider.scrollWidth, //0,
    max: -0, //getBoundariesWidth(),
    from: sliderX.get(),
    velocity: sliderX.getVelocity(),
    power: 0.6,
    bounceStiffness: 400,
    bounceDamping: 20
  })
  .start(sliderX);
});

If you want to use the decay animation:

const { styler, decay, listen, pointer, value, transform } = window.popmotion;

const { clamp } = transform;

const slider = document.querySelector('.carousel');
const divStyler = styler(slider);
// const sliderX = value(0, divStyler.set('x'));
const sliderX = value(0, v => divStyler.set('x', v));


listen(slider, 'mousedown touchstart').start(() => {
 
  
  pointer({ x: sliderX.get() })
    .pipe(({ x }) => x)
    .start(sliderX);
});
  
listen(document, 'mouseup touchend').start(() => {
  
  decay({
    from: sliderX.get(),
    velocity: sliderX.getVelocity()
  }).pipe(clamp(-slider.scrollWidth, 0))
    .start(sliderX);
});
