JGB Slider

A simple vanilla js slider with basic controls, event handlers, and accessible methods for customisation.

Please note:

This is still in progress. The api may change until it's officially at v1.0.0.

Installation

npm install jgb-slider
 
<script src="../dist/jgb-slider.min.js"></script>

let Slider = require('jgb-slider');
import Slider from 'jgb-slider';

Import the styl file

@import "~/jgb-slider/src/js-slider";
 
// or
 
@import "~/jgb-slider/src/slider"; // For mixin
 
// or
 
<link href="./node_modules/jgb-slider/dist/jgb-slider.min.css" rel="stylesheet" />
 

Instantiation

Previous and next buttons as well as bullets are automatically created and managed based on your javascript options.

<div class="example-slider">
    <ol class="example-slider__slider">
        <li class="example-slider__slide">
            <img src="http://unsplash.it/1200/500" />
        </li>
        <li class="example-slider__slide">
            <img src="http://unsplash.it/1200/500?image=123" />
        </li>
        <li class="example-slider__slide">
            <img src="http://unsplash.it/1200/500?image=173" />
        </li>
        <li class="example-slider__slide">
            <img src="http://unsplash.it/1200/500?image=143" />
        </li>
        <li class="example-slider__slide">
            <img src="http://unsplash.it/1200/500?image=423" />
        </li>
    </ol>
</div>

jgbslider();

or

jgbslider({
    selector: '.example-slider',
    slideDuration: 1000, // default set
    autoplay: true, // default is false
    loopThrough: true, // default is false
    onInit: function() {
        alert('Slider initialized')
    }
});

The slider instance attaches itself to the DOM element. Therefore, you can have multiple instances of the slider in the page. You would access it in the following means.

    var instance = document.querySelector('example-slider:first-child').slider;
        instance.stopAutoplay();

The css follows BEM

.block

.block__slider

.block__slide

.block__prev-slide // autogenerated

.block__next-slide //autogenerated

Methods

Goes to the next slide

instance.next();

Goes to the previous slide

instance.previous();

Starts autoplay

instance.autoplay();

End autoplay

instance.stopAutoplay();

Eventhandlers

onStartAutoplay: function() { ... },
 
onStopAutoplay: function() { ... },
 
onInit: function() { ... },
 
beforeSlide: function() { ... },
 
afterSlide: function() { ... }
 

Contributing

The fun part of this slider - is the underlying domain model which was built with pure functions, inspired by elm, redux and the SAM pattern (of which I'm yet to understand well).

Just make a pull request. Any additional logic should have a test to go with it.

npm run # to find out what dev commands you can use

Before you push the project - run a build to generate the dist files and test with either a new example - or an updated example.
