  title: MediaWiki Action articles Mobile API
  description: 'The MediaWiki Action API is the original programmatic interface to MediaWiki, exposed under /w/api.php on every MediaWiki installation. All operations dispatch via the ?action= query parameter. The API supports JSON, XML, and PHP serialization; JSON is the recommended format.


    Wikimedia projects strongly recommend serial (not parallel) calls, the use of maxlag for non-interactive jobs, and a contactable User-Agent header. The Action API remains the primary write interface (edit, upload, login, patrol) even where the Core REST API is also available.'

      summary: Wikimedia REST Get CSS for Mobile Apps.
      description: 'Gets common CSS mobile apps need to properly display pages using Page Content Service.

        In most cases all of the types are needed (preferably in this order):

        * base (Common mobile CSS from ResourceLoader)

        * site (Site-specific, mobile CSS from ResourceLoader, as defined in MediaWiki\:Mobile.css)

        * pcs (CSS for the Page Content Service)


        The `base` and `pcs` responses are the same regardless of what domain is used.

        For these we suggest meta.wikimedia.org.


        You can still pass pagelib for type, but this is a legacy version of the CSS for

        existing app clients.

      description: 'Gets the JavaScript bundle so that clients can have

        convenient access to that for consuming the page HTML.

        Amongst other things,

        * it allows to detect the platform and through that enable platform specific CSS rules,

        * has code to lazy load images on the page,

        * code for collapsing and expanding tables.


        Valid types are pagelib or pcs. Passing pcs will return the JavaScript for the

        Page Content Service. Passing pagelib will return a deprecated legacy version

        of the wikimedia-page-library JavaScript to support existing app clients.
