I need add a custom javascript (bootstrap.js, for example) to the cms mediawiki-1.34.0. I found a way related to downloading the script file and add string
mw.loader.load ('/w/index.php?title=MediaWiki:bootstrap.js&action=raw&ctype=text/javascript');
in http://localhost/WikiRobotNET/index.php/MediaWiki:Common.js
However, this method does not suit me. Is it possible to hook up a script directly in the code? How to do it?
