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

Requirements

MediaWiki 1.36.0 or greater.

While not strictly required, we suggest installing these dependencies to enhance the media search experience.

System-level dependencies

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

MW Extensions

The following Mediawiki extensions are recommended:

• 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

Installation

After the extensions listed above are set up properly, enable the extension by adding wfLoadExtension( 'MediaSearch' ); along with the required config variables to LocalSettings.php.

You might need to run composer install in the extension directory, or in the root directory of your MediaWiki installation if you are using a setup that merges all extension's dependencies into MediaWiki's vendor directory.

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.
