ks-vue-fullpage

A simple, flexible and easy to use Vue plugin to create fullscreen scrolling websites (also known as single page websites or onepage sites). No jQuery needed, pure Vanilla js.

Try it in this fiddle .

• x-axis or y-axis animations
• w/without subtle parallax animations (on both axis)
• multiple events triggered by the plugin on every components, listenable using vm.$ksvuefp

Inspired by the awesome jQuery plugin "FullPage.js" , created by @Alvarotrigo

---

Getting Started

The plugin only works with 2nd version of Vue.js. Also, you'll need to include Velocity and hammerjs in your bundle (or directly in your html page if you choose the good old script tag method).

    npm i --save ks-vue-fullpage

Usage

With Webpack

    import KsVueFullpage from 'ks-vue-fullpage'
    Vue.use(KsVueFullpage)

With Nuxt

Create a ksvuefp.js files in yur plugins folder, and add it to yout nuxt.config.js files with ssr: false option

ksvuefp.js

    import KsVueFullpage from 'ks-vue-fullpage'
    Vue.use(KsVueFullpage)

nuxt.config.js

{
  ...
  plugins: [{
    src: '~/plugins/ksvuefp',
    ssr: false
  }]
  ...
}

With a script tag

    <link rel="stylesheet" href="/dist/ks-vue-fullpage.min.css"></link>
    <script src="/dist/ks-vue-fullpage.min.js"></script>  

Ks-vue-fullpage registers 2 new components:

• "ksvuefp", which is the wrapper for our sections
• "ksvuefp-section", which is the single section wrapper you'll use with v-for

and add $ksvuefp property to every components, available at vm.$ksvuefp

vm.$ksvuefp returns the following datas object

{
  options: [], // Default options (see below) merged with your prop options
  fpLoaded: false, // true when the plugin and his components are totally loaded
  currentIndex: 0, // the index currently shown
  slidingActive: false, // true if sections transition is occuring
  sliderDirection: 'down', // one of 'up' or 'down'
  wWidth: 0, // Integer. current screen width
  wHeight: 0 // Integer. current screen height
}

Example code

    ...
      <ksvuefp :options="options" :sections="sections"> // Where options is an object of options, and sections an array containing our sections datas

        <ksvuefp-section
          class="whatever"
          v-for="(s,index) in sections"
          :section="s"
          :key="s.id"
          :section-index="index"
          :background-image="'url('+ s.img_url +')'"
          :background-color="'#123456'" >

          <h2> {{any_data}} </h2>

        </ksvuefp-section>

      </ksvuefp>
    ...
    <script>
      ...
      data(){
        return {
          sections: [
            {
              id: 1,
              any_data: "I'm section 1",
              img_url: './images/whatever01.jpg'
            },
            {
              id: 2,
              any_data: "I'm section 2",
              img_url: './images/whatever02.jpg'
            },
            {
              id: 3,
              any_data: "I'm section 3",
              img_url: './images/whatever03.jpg'
            }
          ],
          // See below for a list of default options
          options: {
            duration: 800,
            easing: [1, 0, 0, 1],

Remaining tasks

• Add parallax effect on both axis
• Make it Nuxt compatible
• Create demos (in progress)
• Add delay option, to enable content animations before sliding
• Add better responsive features

I'm just a lowly frontend developer trying to master ES6, so suggestions are more than welcome, not only for feature requests but also for coding style improvements.
