An App’s static assets include resources such as images and JSON data.
Requests for static assets are made relative to the
<RootURL>/static URI path. For example, retrieving the icon named
icon.png for a
/channel_header binding would result in the following HTTP request:
GET http://my-app:4000/static/icon.png HTTP/1.1
At this time, binding icons and profile picture overrides are the only static assets that are automatically requested by the Mattermost UI.
