MediaSearch is an alternative, media-focused way to display search results through the Special:MediaSearch page.

Installation

Download and move the extracted MediaSearch folder to your extensions/ directory.
Developers and code contributors should install the extension from Git instead, using:
```
cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/MediaSearch 
```
Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See T173141 for potential complications.)
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'MediaSearch' ); 
```
Configure as required.
While not strictly required, we suggest installing some optional dependencies to enhance the media search experience.
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Optional dependencies

System-level dependencies

ElasticSearch (see here for more information on how to install)

MediaWiki dependencies

CirrusSearch and dependencies, for improved search results & per-mediatype tab support
If you have a Wikibase repository, we strongly recommend also installing these extensions to allow more data to be used to enhance the search results:
- WikibaseMediaInfo
- WikibaseCirrusSearch

Configuration

Extension configuration variables are sets of key-value pairs. They are documented in more detail in extension.json. Config variables should be added to LocalSettings.php. The following config options are available for this extension:

// External search results API (for results from another wiki - e.g. locally testing changes with remote results) $wgMediaSearchExternalSearchUri = 'https://commons.wikimedia.org/w/api.php'; // External entity search base URI (for autocomplete suggestions, optional) $wgMediaSearchExternalEntitySearchBaseUri = 'https://www.wikidata.org/w/api.php';

Coding conventions

JavaScript/Vue

As much as possible, we default to the Vue Style Guide.

For now, we are not using full single-file components because we need to be able to compile Less separately so it can be included immediately before the app loads to style the PHP UI.

CSS/Less

Since Wikimedia UI base variables aren't in core, we require them as a package dependency, then use a shell script to copy them to the lib directory. To update the base variables, require the new version in package.json and install it, then run npm run build-lib to copy the updated file into lib. Commit the updated files.

We're including the base variables in our custom variables file, resources/mediasearch-variables.less. To use them in other files, include mediasearch-variables.less rather than directly including the base file itself.

The CSS class name prefix sdms should be used for extension-level components. sd should be used for base components to keep them extension-agnostic, in case we decide to pull them out into a separate library.
