EX.CO embed events


Embed events are the way to subscribe to events happening in the EX.CO embedded item., They are dispatched to the parent embedding page, in order for the embedding page to subscribe.

How to subscribe


Assuming you have EX.CO story item embedded in your page, you should use the code below in the <body> tag:


 document.body.addEventListener('pbItemEvent', function (e) {
    
    var eventName = e.detail.name;
    var eventData = e.detail.data;
    
    console.log(eventName); // i.e. 'pb.item.scroll-top-into-view'
    console.log(eventData); // i.e. { id: '7cb13e50-8295-4573-ad49-6b5ba7aab278', title: 'my story title', description: 'an example story description' }
 });

Embed when using Content Security Policy (CSP)


The following is a tech guide aimed to help publishers that are using CSP headers and want to embed EX.CO items on their pages.


CSP reference documentation can be found here:



There are many ways to implement CSP on a page, this guide aims to help set the correct CSP attributes depending on Strictness level.


In some cases, some functionality might still be blocked or not work as expected and the attributes will have to be set according to your use case.


Sources we commonly use (this might change /update over time):


Source/Attrubute value

Description

'unsafe-inline'

we load scripts from JS onto the html

*.ex.co

EX.CO domain

*.playbuzz.com

Playbuzz domain (owned by EX.CO)

*.avplayer.com

Channels (mcd) player + analytics

www.google-analytics.com

google analytics

www.google.com

google analytics / recaptcha for Poll & Lead Form

www.googletagmanager.com

Initem ads / Channels ads

www.googleadservices.com

Initem ads / Channels ads

googleads.g.doubleclick.net

Initem ads / Channels ads

www.gstatic.com

recaptcha for Poll & Lead Form

In cases where custom integrations are implemented for an item Pixels/HubSpot etc, these specific sources need to be added to the example below. 3rd party embedded content (ex. YouTube) needs to be added to allowed sources as well.


  • Simple: default-src defines all sources, without going into specific granulation (script-src, frame-src, etc), Images and Videos will load from any source.
<meta http-equiv="Content-Security-Policy" content="default-src 'unsafe-inline' *.ex.co *.playbuzz.com player.avplayer.com www.google-analytics.com www.google.com www.googletagmanager.com www.googleadservices.com googleads.g.doubleclick.net www.gstatic.com; img-src * data: blob; media-src * data: blob:; worker-src blob:">
  • Strict media sources: like the example above but with media sources limited to media uploaded to Ex.Co, AJAX requests are limited as well.
<meta http-equiv="Content-Security-Policy" content="default-src 'unsafe-inline'; script-src 'unsafe-inline' *.ex.co *.playbuzz.com *.avplayer.com www.google-analytics.com www.google.com www.googletagmanager.com www.googleadservices.com googleads.g.doubleclick.net www.gstatic.com; frame-src *.ex.co *.playbuzz.com www.google.com doubleclick.net; connect-src *.ex.co *.playbuzz.com; img-src *.ex.co *.playbuzz.com *.avplayer.com www.google-analytics.com www.google.com data:; media-src *.ex.co *.playbuzz.com data: blob:;">
  • Strict with granular attributes: This will allow most Ex.Co functionality but defines each CSP attribute separately. Any additional sources (For Pixels/Hubspot/3rd Party embeds like Youtube/etc) will need to be added manually under the correct attribute.
<meta http-equiv="Content-Security-Policy" content="default-src 'unsafe-inline'; script-src 'unsafe-inline' *.ex.co *.playbuzz.com *.avplayer.com www.google-analytics.com www.google.com www.googletagmanager.com www.googleadservices.com googleads.g.doubleclick.net www.gstatic.com; frame-src *.ex.co *.playbuzz.com www.google.com doubleclick.net; connect-src *.ex.co *.playbuzz.com; img-src *.ex.co *.playbuzz.com *.avplayer.com www.google-analytics.com www.google.com data:; media-src *.ex.co *.playbuzz.com data: blob:;">

Embed Best Practices

  • Separate the embed script tag from the div tag, put the script tag in the html head and the div where you would like the item to render.

Bad Example:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<script>(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src='https://stg-embed.ex.co/sdk.js';fjs.parentNode.insertBefore(js,fjs);}(document,'script','playbuzz-sdk'));</script>
<div class="playbuzz" data-id="5e51b385-64c4-4e0b-90ea-b9793637377c" data-show-share="false" data-show-info="false"></div>
</body>
</html>


Good Example:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<script>(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src='https://stg-embed.ex.co/sdk.js';fjs.parentNode.insertBefore(js,fjs);}(document,'script','playbuzz-sdk'));</script>
</head>
<body>
<div class="playbuzz" data-id="5e51b385-64c4-4e0b-90ea-b9793637377c" data-show-share="false" data-show-info="false"></div>
</body>
</html>


  • If you have more than one items in the same page, do not include the embed script tag twice,


Bad Example:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<script>(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src='https://stg-embed.ex.co/sdk.js';fjs.parentNode.insertBefore(js,fjs);}(document,'script','playbuzz-sdk'));</script>
<div class="playbuzz" data-id="5e51b385-64c4-4e0b-90ea-b9793637377c" data-show-share="false" data-show-info="false"></div>
<script>(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src='https://stg-embed.ex.co/sdk.js';fjs.parentNode.insertBefore(js,fjs);}(document,'script','playbuzz-sdk'));</script>
<div class="playbuzz" data-id="7afc1480-b83c-46d4-a8ea-e6785f392cec" data-show-share="false" data-show-info="false"></div>
</body>
</html>

Good Example:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<script>(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src='https://stg-embed.ex.co/sdk.js';fjs.parentNode.insertBefore(js,fjs);}(document,'script','playbuzz-sdk'));</script>
</head>
<body>
<div class="playbuzz" data-id="5e51b385-64c4-4e0b-90ea-b9793637377c" data-show-share="false" data-show-info="false"></div>
<div class="playbuzz" data-id="7afc1480-b83c-46d4-a8ea-e6785f392cec" data-show-share="false" data-show-info="false"></div>````
