Draggable slider breaks on resize

[meesrttn 4 Likes (Newbie)]

With this function I create a slider:

	function createDragger() {
		dragger && dragger[0].kill()
		
		dragger = Draggable.create( wrapper, {
			type:'x', 
			edgeResistance:0.5, 
			throwProps: true, 
			bounds: document.querySelector( '.image-slider__container' ),
			lockAxis:true,
			zIndexBoost: false,
			snap: function( value ) {
				const curIndex = getClosestIndex( this.startX, bounds, bigNum, -bigNum ),
					prevIndex = curIndex ? curIndex - 1 : 0,
					nextIndex = ( curIndex === bounds.length - 1 ) ? curIndex : curIndex + 1
				return bounds[ getClosestIndex( value, bounds, bounds[prevIndex], bounds[nextIndex] ) ]
			},
			minimumMovement:6,
			maxDuration: .4,
			overshootTolerance:0.05,
			onThrowComplete: function()
			{
				currentActive = Math.floor( this.x / ( -( slideWidth * 5 ) / ( slides.length - 1 ) ) )
				const active = document.querySelector( '.image-slider__card.active' )
				if( active ) active.classList.remove( 'active' )
				slides[currentActive].classList.add( 'active' )
				setPagination( currentActive )
			},	  
		} )	
		dragger[0].startX = 0
	}

Then this optimizedResize function fires on resize.

	optimizedResize.add( () => {
		bounds = slides.map( item => -item.getBoundingClientRect().left )
		slideWidth = slides[0].getBoundingClientRect().width
		createDragger()
	} )

But when resizing the view of the slider remains the same and breaks.

Does anyone know how to keep the slides neatly in their view?

getBoundingClientRect is going to give you incorrect results if you're not on the first slide. Try something like this on resize.

• save current slide index
• move to first slide
• calculate bounds
• move back to current slide

Added changes to CodePen, now works as expected!

Thank you
