Revision as of 22:23, 18 September 2020

Wikis based on the new Unified Community Platform (UCP) may look or behave differently to what is described below.
See this page for more information on the new platform.

Extensions are features and add-ons developed for MediaWiki, the software platform that Fandom runs on. They are designed by Fandom staff or third-party developers for the purpose of either expanding the function of a wiki or overriding a built-in MediaWiki feature for customization purposes.

How to request an extension

First, verify that the extension you are looking for does not exist already on your community. You can check this by going to Special:Version and looking under the "installed extensions" section or checking the extension's parser function or tag against the "tags" and "hooks" section at the bottom of that page. Fandom already has a significant number of extensions enabled by default.

Many other extensions already exist in the Fandom codebase and can be enabled upon request. You can check what extensions Fandom offers later in this page. Some basic content tools, such as Variables, are automatically enabled by staff when requested. In the case of other complex extensions, such as DPL, a staff member will usually ask a few questions first to ensure that the extension you are asking for is in fact the ideal solution. Other extensions, where the resulting site configuration may be dramatically changed (such as AbuseFilter), will be enabled at staff discretion depending on the context of the request.

If Fandom does not offer a particular extension, you may request Fandom engineering team investigate installing it by using Zendesk and linking to the MediaWiki extension page along with some rationale as to why it's needed. Please be aware that the engineering team may take a few months to review the extension and that most extensions will be rejected. This is mainly due to the amount of rewriting an extension would require to live on the Fandom codebase servers. As such, it's always good to ask yourself, when looking at an extension on MediaWiki.org, whether the extension is up to date, is well-maintained, and allows for a caching layer. If the answer to any of these questions is no, chances are Fandom will not be able to install the extension.
