|[[Skin:WikimediaApiPortal|WikimediaApiPortal]]
| [[phab:project/view/4822/|#WikimediaApiPortal]]
|WikimediaApiPortal is a skin for MediaWiki created by the Wikimedia Foundation [[Core Platform Team]] in 2020 as part of the [[Platform Engineering Team/API Value Stream|API Gateway initiative]]. The skin is designed to mimic the look and feel of conventional developer portals by incorporating header and sidebar navigation elements and following the Wikimedia Design Style Guide. The skin uses the Bootstrap CSS framework, [[OOUI]] library, and Mustache templates. The skin was created for use with the Wikimedia [[wikitech:API Portal|API Portal]], so some elements of the design such as the site logo and footer are specific to Wikimedia.

== Upstream projects and libraries ==
{{TNT|main|Upstream projects}}
There are many [[upstream projects]] on which MediaWiki, extensions, and/or Wikimedia depend. Some of them were "invented here", as stand-along libraries, or split out as part of the [[Library infrastructure for MediaWiki]] project. Some of them are widely-used third party tools to which community members provide improvements or support. Others are merely used with gratitude.

== Services and administration ==

:''See also: [[wikitech:Category:Services]] and [[m:FLOSS-Exchange]]''

{{Note}} If you need immediate help with a systems administration question, please go into the [[MediaWiki on IRC|IRC]] channel {{irc|wikimedia-operations}} and find [[wikitech:Interrupts Rotation|the person currently on Ops Clinic duty"]] (as listed in the <code>/topic</code>).
