Creating Web Story experiences using the Web Story Player on non-AMP sites

What is the Web Story Player?

The Web Story Player is the best way for you to give users a rich user experience on your sites using Web Stories. Think of it like a video player: having a single video in your device is fine, but put it in a video player live on the web, and it unlocks a number of features and benefits: There’s additional controls (e.g. captions), it lives among millions of other videos that can provide related content at the end of your original video – which adds discoverability, and more.

You can think similarly of the web story player. By only linking to a single story, you can miss out on a number of features and experiences that are found in other story platforms (e.g. Instagram, Snapchat) and are natural to story users. See table below for a few examples.

This guide contains mainly features that are available on the non-AMP version of the player. To learn what's possible with the AMP-compatible version of the player, visit the Integrate stories in AMP pages article.

Common implementations

You can use the web story player to create a number of experiences in your own platform ranging from carousels to singleton cards to directly embedding the Story into a page. We have developed a detailed UX guide with best practices to go with these examples. The most common pattern that we recommend is a carousel. We will outline the best practices to create such an experience, but you should feel free to experiment and implement what works best for your use case. We will share a broader list of UX patterns in the coming weeks.

Web Story Player carousel

A carousel of stories has multiple stories next to each other. It generally includes a preview of the story like a thumbnail and title. When clicked, it will open the story. The user can then consume the story or swipe between stories.

Important aspects in this sample:

  • On desktop:
  • On a mobile device:
    • Swiping is supported to navigate between stories
    • The “scroll background page” is disabled to yield that gesture for swiping to close
    • Entry point cards have smaller size than desktop
    • There are no background cards (since there is no hover in mobile)
    • Swiping down is enabled to close the story
  • On both screen sizes:

Adding stories to the player

There are three main ways to add stories to the player.

  1. Declaring them as anchor tags inside the player HTML.
  2. Using the fetch behavior to fetch more stories from an endpoint.
  3. Using the add() API to add a story or multiple stories.

If you only want to display a static set of stories in your player, your best option is (1). But if you want to dynamically add stories, you can do so with options (2) or (3).

Display stories

The simplest way to display and add stories to the player is to declare them directly in the HTML where the <amp-story-player> element is located as <a> tags. See code sample in the “Display a Web Story” section of the guide.

You can create an "infinite scroll" experience as the user navigates through them in the Web Story Player. To do so, include the fetch action and specify an endpoint in the JSON configuration. The player automatically fetches more stories as the user gets closer to the last loaded story. You can customize fetched stories for users by setting up a backend personalization system and using the fetch action to serve them.

Add stories using the add() API

You can manually add a story or multiple stories using the add() API.

Customizable UI

The player unlocks a number of features that allow you to customize the UI of the system display. In addition to controls, you can also add attribution for the stories inside the player, so that the user knows who published the story they are currently interacting with.

Add attribution for creator / publisher

Attribution in web stories

Creator’s title at the top of the story

The story attribution displays the entity or publisher's name and logo. When clicked, it will navigate the user to either the entity's URL or the publisher's canonical domain.

To display the attribution on the stories, use the player's display and attribution options. See the JSON configuration.

The data will come from the <amp-story>'s metadata attributes in the story's document as described:

  • For the logo: the entity-logo-src attribute (if provided), otherwise the publisher-logo-src attribute.
  • For the string of text: the entity attribute (if provided), otherwise the publisher attribute.
  • When the attribution is clicked, it will navigate the user to a URL. This will come from entity-url attribute if provided, otherwise it will use the story's canonical domain.

Read more about these attributes on the Metadata Guidelines of amp-story.

Modify & add existing controls

This includes a “close” button for creating lightbox-like experiences and a “skip-to-next” button for navigating between stories on desktop. You can also add your own custom controls and listen to their events to perform custom actions. See examples below to get an idea of what you can do.

To configure them, specify a JSON configuration with the type=”application/json” attribute as a child of the <amp-story-player> element.

Inside the configuration, specify an array of “controls”. The “controls” structure is described below.

The configuration will end up looking like the following:

<amp-story-player>

 <script type="application/json">
   {
     "controls": [
       {
         "name": "close",
         "position": "start"
       },
       {
         "name": "skip-to-next"
       }
     ]
   }
 </script>

<a href="./story1.html"> ... </a>
<a href="./story2.html"> ... </a>
</amp-story-player>

Example #1 - Close button on the start position

Since the default (when including a custom UI configuration JSON) will set all these buttons to the right, all we have to do is move the close button to the start.

<amp-story-player>
 <script type="application/json">
   {
     "controls": [
       {
         "name": "close",
         "position": "start"
       }
     ],
   }
 </script>
 ...

Close control of the player in the start position

Example #2 - Showing skip-to-next story on desktop

On desktop, you can now display a button that navigates from the current story to the next one. It will also automatically be disabled once the user reaches the end of the stories in the player.

<amp-story-player>
 <script type="application/json">
   {
     "controls": [
       {
         "name": "skip-to-next"
       }
     ],
   }
 </script>
 ...
</amp-story-player>

Skip-to-next control of the player

Example #3 - Changing the icon of the close button

<amp-story-player>
 <script type="application/json">
   {
     "controls": [
       {
         "name": "close",
         "backgroundImageUrl": "data:image\/svg+xml;charset=utf-8,<svg width=\"24\" height=\"24\" viewBox=\"0 0 24 24\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path fill-rule=\"evenodd\" clip-rule=\"evenodd\" d=\"M5.77778 9.33333H4V4H9.33333V5.77778H5.77778V9.33333ZM4 14.6667H5.77778V18.2222H9.33333V20H4V14.6667ZM18.2222 18.2222H14.6667V20H20V14.6667H18.2222V18.2222ZM14.6667 5.77778V4H20V9.33333H18.2222V5.77778H14.6667Z\" fill=\"white\"\/><\/svg>",
         "position": "start"
       }
     ]
   }
 </script>
 ...
</amp-story-player>

Close control of the player with custom icon

Modify behavior

There are a number of options for customizing the behavior of the player. Read through the following sections to get an idea of what you can do.

Circular wrapping

If you want your users to go back to the first story after they finish the last one, you can enable the circular wrapping option.

Rewind stories on the background

If you want to rewind the stories that users have already seen in the player, you can do so using the rewind() API.

Programmatic navigation

You can programmatically navigate between stories and pages inside of the player. This can be useful if you want to create your own navigational buttons outside the player, or if you want to switch between pages depending on an event, for example. To do so, use the go() and show() APIs and their variations.

Optimize performance and SEO

The player does a number of things in the background to ensure it’s only using the resources it needs at any given moment. That being said, there’s a few things you can do on your end to make sure your site performs well while using the player.

For players above the fold

If you wish to embed stories above the fold (in the upper half of a web page; visible without scrolling down the page), we recommend waiting until a user interaction to load and play the first story. To do this, follow the following steps:

  1. Disable autoplay with the JSON configuration.
  2. Add a user interaction which will start playing the story.
  3. Use the player API to call play() when the user interaction is detected.

For players below the fold

Players below the fold are automatically optimized for performance and will only preload the first story until a scroll is detected. Once the player is visible in the viewport, the story will start playing.
