Javascript SDK

You can use Streams JS SDK to send messages from the client side to your application.

Embed the script code between the <head> </head> tags inside the page you embedded your Streams Link via iframe.

<script src="https://app.vagon.io/vagonsdk.js"></script>

Despite you added the JS SDK script between the tags in your client code, if you can not establish a connection, please be sure that you copied the iFrame tag from the Vagon Streams dashboard.

If you manually created your iFrame code by adding your Streams Link, please check that you applied the id tag and other required iFrame properties correctly from the sample code below.

<iframe id="vagonFrame" allow="microphone  *; clipboard-read *; clipboard-write *; encrypted-media *;" src="_Stream_URL_"/>

Then you will be able to use the JS methods to create your custom user experience for your application Stream.
