SimpleSlider allows you to simply implement Sliders with mobile app grade gesture handling. It doesn't limit itself to images. You can place in slides any HTML content you want.
As you could have noticed, we use SimpleSlider instances inside React components and take full imperative approach.
The reason for this is that slider UI state is complicated (position, animation, speed, etc) and requires heavy orchestration of state variables (not every combination of state variables is correct). If we make slider dummy, this state management logic would have to go to parent. This doesn't make sense because its slider who knows how to manage state logic. This means that calling SimpleSlider methods is simply th best solution to drive internal state changes.
We tried it and it failed.
First, we need to have ref to this ReactSimpleSlider component always. To have access to all methods (moveTo, visibleSlides, etc).
We also got to conclusion that layout method must be always called in component that instantiates ReactSimpleSlider, which complicates API and doesn't allow us for simply putting ReactSimpleSlider to render() and keeping parent component stateless. The reason for that is that if layout is called inside ReactSimpleSlider, SimpleSlider automatically calls all the events (onActiveSlidesChange, onMove etc). Those events are usually used by parent component. And when they're called, parent component still doesn't have ReactSimpleSlider ref initialized, because it's child who is being initialized at the moment. This led to conclusion that it's parent who should control everything and we shouldn't put partial control to ReactSimpleSlider.
Also, all that ReactSimpleSlider did was rewrite API of SimpleSlider to props. That casued many bugs, where SimpleSlider did have some method and ReactSimpleSlider didn't. It doesn't make sense to copy APIs and DX doesn't seem to be much better with props.
Another thing is that having slideMargin, slideSnapOffset etc functions in render is tempting to use () => 200 syntax inside render method and instantiate new local methods every time render is called which is super inefficient if we have many of that methods.
Also, all the components (pager, arrows, touchspace) require Slider instance and the code of parent of ReactSimpleSlider was full of this.sliderRef.current.slider.sth, while without we have only this.slider.sth.
At the end of the day SimpleSlider is very imperative component and it should stay this way within React (or Vue) realm.
