Add stories EVERYWHERE

MWHAHAHAHA. Seriously. This script is a copy of Facebook Stories of a copy of Facebook Messenger Day 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.

  id: '',                // timeline container id or 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 - may decrease performance

      callback();  // on open story viewer
    },

    'onRender': function(item, mediaHTML) {
      return mediaHTML; // on render story viewer, use if you want custom elements
    },

Add/update a story:

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 - if local storage is used, you don't need to care about this 

    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 - if local storage is used, you don't need to care about this
        }
    ]
}

Alternate call

In your HTML:

<div id="stories">

    <!-- story -->
    <div class="story" data-id="{{story.id}}" data-last-updated="{{story.lastUpdated}}" data-photo="{{story.photo}}">
        <a href="{{story.link}}">
            <span><u style="background-image:url({{story.photo}});"></u><span>
            <span class="info">
                <strong>{{story.name}}</strong>
                <span class="time">{{story.lastUpdated}}</span>
            </span>
        </a>
        
        <ul class="items">
        
            <!-- story item -->
            <li data-id="{{story.items.id}}" data-time="{{story.items.time}}" class="{{story.items.seen}}">
                <a href="{{story.items.src}}" data-type="{{story.items.type}}" data-length="{{story.items.length}}" data-link="{{story.items.link}}" data-linkText="{{story.items.linkText}}">
                    <img src="{{story.items.preview}}">
                </a>
            </li>
            <!--/ story item -->
            
        </ul>
    </div>
    <!--/ story -->
    
</div>

Then in your JS:

var 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.
