ExtJSBase adds support for the ExtJS framework for use within MediaWiki. Several extensions (such as BlueSpiceFoundation ) depend on the ExtJS framework, thus, it is a requirement for these extensions to function. Wherever ExtJSBase is required for an extension to work, it is referenced accordingly on the extension page.


  • Download and place the file(s) in a directory called ExtJSBase in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'ExtJSBase' );
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
