Add stories EVERYWHERE

MWHAHAHAHA. Seriously. This script is a copy of Facebook Stories of a copy of Facebook Messenger Day (RIP) of a copy of WhatsApp status of a copy of Instagram stories of a copy of Snapchat stories.

You can read stories from any endpoint (JSON, Firebase, etc.) and the script will do the rest.

How to use

You can download this git repository or install via npm install zuck.js

Initialize:

let stories = new Zuck(`{{element id string or element reference}}`, {
  skin: 'snapgram',      // container class
  avatars: true,         // shows user photo instead of last story item preview
  list: false,           // displays a timeline instead of carousel
  openEffect: true,      // enables effect when opening story
  cubeEffect: false,     // enables the 3d cube effect when sliding story
  autoFullScreen: false, // enables fullscreen on mobile browsers
  backButton: true,      // adds a back button to close the story viewer
  backNative: false,     // uses window history to enable back button on browsers/android
  previousTap: true,     // use 1/3 of the screen to navigate to previous item when tap the story
  localStorage: true,    // set true to save "seen" position. Element must have a id to save properly.
  reactive: true,        // set true if you use frameworks like React to control the timeline (see react.sample.html)
  rtl: false,            // enable/disable RTL

  stories: [ // array of stories
    // see stories structure example
  ],

  callbacks:  {
    onOpen (storyId, callback) {
      callback();  // on open story viewer
    },

    onView (storyId) {
      // on view story
    },

    onEnd (storyId, callback) {
      callback();  // on end story
    },

    onClose (storyId, callback) {
      callback();  // on close story viewer
    },

    onNavigateItem (storyId, nextStoryId, callback) {
      callback();  // on navigate item of story
    },

    onDataUpdate (currentState, callback) {
      callback(); // use to update state on your reactive framework
    }
  },

  template: {
    // use these functions to render custom templates
    // see src/zuck.js for more details

    timelineItem (itemData) {
      return ``;
    },

    timelineStoryItem (itemData) {
      return ``;
    },

    viewerItem (storyData, currentStoryItem) {
      return ``;
    },

    viewerItemPointer (index, currentIndex, item) {
      return ``;
    },

    viewerItemBody (index, currentIndex, item) {
      return ``;
    }
  },

  language: { // if you need to translate :)
    unmute: 'Touch to unmute',
    keyboardTip: 'Press space to see next',
    visitLink: 'Visit link',
    time: {
      ago:'ago', 
      hour:'hour', 
      hours:'hours', 
      minute:'minute', 
      minutes:'minutes', 
      fromnow: 'from now', 
      seconds:'seconds', 
      yesterday: 'yesterday', 
      tomorrow: 'tomorrow', 
      days:'days'
    }
  }
});

Add/update a story (timeline item):

stories.update({item object});

Remove a story:

stories.remove(storyId); // story id

Add/remove a story item:

stories.addItem(storyId, {item object});
stories.removeItem(storyId, itemId);

Stories structure example

A JSON example of the stories object:

{
  id: "",               // story id
  photo: "",            // story photo (or user photo)
  name: "",             // story name (or user name)
  link: "",             // story link (useless on story generated by script)
  lastUpdated: "",      // last updated date in unix time format
  seen: false,          // set true if user has opened

  items: [              // array of items
    // story item example
    {
      id: "",       // item id
      type: "",     // photo or video
      length: 3,    // photo timeout or video length in seconds - uses 3 seconds timeout for images if not set
      src: "",      // photo or video src
      preview: "",  // optional - item thumbnail to show in the story carousel instead of the story defined image
      link: "",     // a link to click on story
      linkText: "", // link text
      time: "",     // optional a date to display with the story item. unix timestamp are converted to "time ago" format
      seen: false   // set true if current user was read,
      [customKey]: "", //  custom-value
      [anotherCustomKey]: "" // another-custom-value
    }
  ]
}

Alternate call

In your HTML:

<div id="stories">

    <!-- story -->
    <div class="story {{ story.seen ? 'seen' : '' }}" data-id="{{storyId}}" data-last-updated="{{story.lastUpdated}}" data-photo="{{story.photo}}">
        <a class="item-link" href="{{story.link}}">
          <span class="item-preview">
            <img src="{{story.photo}}" />
          </span>
          <span class="info" itemProp="author" itemScope="" itemType="http://schema.org/Person">
            <strong class="name" itemProp="name">{{story.name}}</strong>
            <span class="time">{{story.lastUpdated}}</span>
          </span>
        </a>
        
        <ul class="items">
        
            <!-- story item -->
            <li data-id="{{storyItemId}}" data-time="{{storyItem.time}}" class="{{storyItem.seen}}">
                <a href="{{storyItem.src}}"
                
                 data-type="{{storyItem.type}}" 
                 data-length="{{storyItem.length}}" 
                 data-link="{{storyItem.link}}" 
                 data-linkText="{{storyItem.linkText}}" 
                 
                 data-custom-key="{{storyItem.custom-key}}" 
                 data-another-custom-key="{{storyItem.another-custom-key}}">
                    <img src="{{storyItem.preview}}" />
                </a>
            </li>
            <!--/ story item -->
            
        </ul>
    </div>
    <!--/ story -->
    
</div>

Then in your JS:

let stories = new Zuck({{element id string or element reference}}); 

Tips

• You can use with autoFullScreen option (disabled by default) to emulate an app on mobile devices.
• If you use Ionic or some js that uses location.hash, you should always disable the "backNative" option which can mess your navigation.

Limitations

On mobile browsers, video can't play with audio without a user gesture. So the script tries to play audio only when the user clicks to see the next story. When the story is playing automatically, the video is muted, but an alert is displayed so the user may click to turn the audio on.

Stories links opens in a new window too. This behaviour occurs because most websites are blocked on iframe embedding.
