Lory

FWIW, this vanilla slider is superseded by and obsolete for Splide which is also vanilla.

Lory is a touch enabled minimalistic slider written in vanilla JavaScript.

Requirements

• Lory library:
  • Download Lory archive from https://github.com/meandmax/lory
  • Extract it as is, rename "lory-master" to "lory", so the assets are at:
    /libraries/lory/dist/lory.min.js
• Blazy (2.x-rc7+),
  to reduce DRY stuffs, and as a bonus, advanced lazyloading such as delay lazyloading for below-fold sliders, iframe, (fullscreen) CSS background lazyloading, breakpoint dependent multi-serving images, lazyload ahead for smoother UX.

Optional Requirements

• Drupal 8.7 drops supporting IE9. If you need to support old browsers (IE9), include requestAnimationFrame polyfill into your own custom libraries from any below:
  • https://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
  • https://gist.github.com/paulirish/1579671

  Note: IE10+ supports rAF, no need to include it.
  Read more to decide if it is worth to support old IE:
  Support for older versions of Internet Explorer ended

• Specific to arrowDown feature, it is only enabled if jumper.module exists.

Known Issues

Lory is only useful for pretty simple slideshow/ carousel needs when size matters. You have to do your own custom needs for those which are not given by default as the author refuses to bake more features in. If you need a more robust solution OOTB, check out Slick.
