The Popups extension displays page and reference previews when hovering over a link to an article or respectively to a reference. The former consists of summaries of an article's content, the latter shows the full content of the reference.
The extension is an initiative of the Design team, inspired by the popular Navigation popups gadget. Currently this feature is available on all Wikipedias by default for logged-out users. A description of how the extension functions and more information on its use on Wikimedia projects is available at Page Previews.
The Reference Previews feature was added eventually and aims to fulfill a wish from the German-speaking community's Technical Wishlist. A more detailed description and more information on its use is available at 도움말:각주 미리 보기.
기본적으로 설치해야 할 것
This extension has a hard dependency on 확장기능:TextExtracts and Extension:PageImages. There are also optional dependencies on 베타 기능 (if you want to enable the Reference Previews as beta feature), and Extension:EventLogging and Extension:WikimediaEvents (for instrumentation).

Page previews API
Every project is different, and what displays in your previews is highly dependent on the content inside your wiki.
Extension:Popups has been optimised to work with Wikipedia-like content (e.g. wikitext). If your wiki is using a different kind of content handler (for example as is the case for Wikibase) it will need to provide its own API.
The API can be written in any language, but the response of the API must match the spec defined here:
Defining new APIs is out of scope for the Popups extension.
Once defined, you can configure page previews to point to your API using
$wgPopupsRestGatewayEndpoint configuration option.

Page previews content
The page preview popups show an image (if one is available) and a small text excerpt.
The image comes from the Extension:PageImages which returns the single most appropriate thumbnail associated with an article. It ignores maintenance templates, stubs, flag icons etc.
The page previews can be configured with any compatible API that is compatible with the Page content service summary endpoint using
$wgPopupsRestGatewayEndpoint. For third parties we encourage using the Page Content Service to enjoy using Popups with your local wiki.
Reference previews content
The content in the reference preview popups is taken directly from the reference section on the page itself. No external services are involved here. If the content exceeds the popup size scrollbars are shown so everything can be looked at.
The reference types displayed are set by using specific CSS-classes on the
<cite>-tag that can be used to encapsulate the content of a reference e.g.
Currently the following types are supported:
Apart from that there is always a generic fallback if neither the cite tag was found nor an appropriate class was used.
Please note, that it's not recommended to use the CSS-classes directly in wikitext, but rather by creating templates.
This extensions currently has only one renderer, that is for ordinary pages.
New renderers for different kind of pages, or things like references can be easily added.
One needs to create a new object with the following methods:
- Users of the Translate extension should note that Page Previews requests previews in the content language of the page. If the preview contains a complete translatable block, then it will be translated. If, however, the preview contains an incomplete translateable block – because a sentence is cut off, say – then it isn't translated and will be displayed in the content language of the page. If you are observing this behavior, then you should consider marking up individual sentences in your lead section.
- T167852 is for a technical audience but has more information on the underlying problem.
- Longer math formulas cutting off in preview - long math or chemical formulas (formulas wider than the preview width) display as truncated in previews. We were not able to add a gradient in order to indicate that the formula is continued on the article itself.
Why can't I copy and paste text from a preview?
At time of writing, the cons of doing so outweigh the pros. Essentially it boils down to decreasing the touch area to read the article in full. Once Page Previews is deployed on English and German Wikipedia, feel free to reopen this task and reignite the discussion, but right now we have no plans.
How can I change the image that I see on preview?
How can I remove content from a page preview?
Any element marked with the
noexcerpt class will be stripped from the summary.
Where do summaries come from?
These are provided by the Summary REST API.
Why are parenthetical stripped?
There's a good discussion going on in T91344 in Phabricator. If you have any views on this or see any problems relating to this, please let us know there.
Why don't I see Popups outside of content namespaces?
Popups appear on links to pages in content namespaces only. This is a limitation of Popups; TextExtracts are available from other namespaces. You may work around this by appending more namespaces into $wgContentNamespaces.
