Globals

[mw](mw.html)

The mw object is the historical entry point for MediaWiki's public-facing frontend API. In some cases, APIs are available on the mw object in addition to inside a [module](modules.html). Generally, the use of a module is recommended where possible as it is more robust to changes in how code is organized.

[Hooks](Hooks.html)

The [mw.hook](mw.html#.hook) method provides an API to run JavaScript code when certain events occur. For example, you can use a hook to run code after a page is edited. For a list of stable hooks provided by MediaWiki core, see [Hooks](Hooks.html).

Extensions and skins can also add hooks. See the documentation for those codebases for more information on the hooks they provide.

[window](window.html)

Historical methods defined on the window object.
