Slick Carousel

Slick is a powerful and performant slideshow/carousel solution leveraging Ken Wheeler's Slick carousel. See http://kenwheeler.github.io/slick

Slick has a lot of options, please start with the very basic working samples from Slick Example.

Samples Demo

Versions

• 8.x-2.1+ depends on core >= 8.8, (read more)
• 8.x-2.x depends on core >= 8.6, with oEmbed, and without VEF/ VEM, requires Blazy 2.x
• 8.x-1.x has optional integration with VEF/ VEM, requires Blazy 1.x.
• 7.x-3.x (8.x backport WIP) requires PHP 5.6+ and a proper installation with an autoloader module, see Blazy for details. And its requirements.

Requirements

• Slick library (1.6+ and <= 1.8.1):
  Master branch is not supported. Instead download, rename one of the official slick releases to slick, so the assets are available at:
  • sites/../libraries/slick/slick/slick.css
  • sites/../libraries/slick/slick/slick-theme.css (optional if a skin is chosen)
  • sites/../libraries/slick/slick/slick.min.js

  Specific to D8, remove "sites/.." part mentioned elsewhere, so the libraries are:
  /libraries/slick/slick/slick.min.js, etc.

• Libraries, D7 and D8.9 below with Composer. D8.9+ has library finder in core.
• [Optional] jqeasing, so available at:
  sites/../libraries/easing/jquery.easing.min.js
  Fallback for old browsers, ignorable to use CSS3 easing alone.
• D8 and Slick 3.x: Blazy and PHP 5.6+. Slick branch must be similar, or later than Blazy. Checkout Versions below.
• D7 only:
  • jQuery Update for jQuery 1.7+.
  • CTools. Only core CTools is needed. If Views installed, CTools is already installed.

Installation

Manual:

Install the module as usual, more info can be found on:

Quick perfomance tips

• Use lazyLoad "ondemand" / "anticipated" (v1.6.1+) for tons of images, not "progressive". Unless within an ajaxified lightbox.
• Choose lazyload "Blazy" for carousels below the fold to delay loading them.
• Tick "Optimized" option on the top right of Slick optionset edit page to free up some bytes.
• Use image style with regular sizes containing effect "crop" in the name. This way all images will inherit dimensions calculated once.
• Disable core library "slick-theme.css" as it contains font "slick" which may not be in use when using own icon font at:
  /admin/config/media/slick/ui
• Use Blazy multi-serving images, core Responsive image (D8), or Picture (D7), accordingly.
• Uninstall (not only disabled) Slick UI at production.
• Enable Drupal cache, and CSS/ JS assets aggregation.
• Concerns about Slick performance? Check this out, we got a little benchmark.

Troubleshooting

• With a combination of options, Slick offers degree of flexibility to some extent. With great flexibility, comes great possibility, for better or worse, or fun with some advanced Slick examples. If worse, check out a few troubleshooting, known issues, and gotchas before for just in case it is already identified.
• If any issue with displays at D7, be sure to update your jQuery version to 1.7+.
• Any of Slick sub-modules branch must match this module branch. DEV for DEV. Full for full release.
