:groups¶

• :enabled Whether groups are enabled

:events¶

• :enabled Whether events are enabled

:media_proxy¶

• enabled enable the media proxy
• proxy_opts options for the media proxy
  • redirect_on_failure whether to redirect to the original media if proxying fails
  • max_body_length how big the media can be
  • max_read_duration how long we can wait for the remote media
  • http
    • follow_redirect whether we follow redirects

:html_hooks¶

Allows to inject raw HTML code into the app main page.

• :app_index_html_head_first inject raw HTML code before the first node of head element

• :app_index_html_body_first inject raw HTML code before the first node of body element
• :app_index_html_body_last inject raw HTML code after the last node of body element

These hooks can by used to add custom styles, scripts or HTML elements to the webapp.

The value of the key must be of type string but can be defined by any Elixir code that return a string. It could be:

• just a string like "<script>console.log(\"app_index_html_head_last\");</script>"
• or a function call like File.read!("/path/to/a/html/snippet.html")

By default, html hooks are not defined. Hence nothing is injected into the app main page.
