Replacements for the Widgets extension

Following the permanent removal of the Widgets extension due to a security vulnerability, and the potential for future risk, here are some viable replacement options:

Extensions: the EmbedVideo, TimedMediaHandler, Video, or YouTube extensions may be viable replacements.

JavaScript:

$( '#discord-widget' ).html( '<iframe src="https://discord.com/widget?id={SERVER_ID}&theme=dark" width="{WIDTH}" height="{HEIGHT}" allowtransparency="true" frameborder="0" sandbox="allow-popups allow-popups-to-escape-sandbox allow-same-origin allow-scripts"></iframe>' );

HTML:

<div id="discord-widget"></div>

Add the JavaScript to either MediaWiki:{Skin}.js, or MediaWiki:Common.js
Add the HTML to any wiki page or template you wish to display the embedded IFrame.

Note: If the URL you are attempting to frame is blocked by the Miraheze content security policy, it will not work. The current URLs that will work (as of 2022-11-1) are listed below:

# Only add a domain pursuant to the policy below. Please also be restrictive in which list.
# See https://meta.miraheze.org/wiki/Tech:CSP_Policy.
