taken from discussions pkg controller

// automatically run by the package. Let's setup some events
   public function on_start() {  
      Events::extendPageType('discussion', 'on_page_view');
      Events::extendPageType('discussion_post');
   }

Note that you will also need to include this at the top of your package's on_start function:

if (!defined('ENABLE_APPLICATION_EVENTS')) {
   define('ENABLE_APPLICATION_EVENTS', true);
}

you only need that in versions less than 5.4

Sweet! I didn't know that (obviously).
Do you know how this works? Are events always on by default, or is there some check for if a package added an event or not?

Thanks!

i think they are always on by default, its not like its resource consuming, it just fires a function each time Event::Fire is triggered,

You only need to define ENABLE_APPLICATION_EVENTS to true in config/site.php if you plan on using config/site_events.php to store custom events. You don't need to enable it there if you want to use events defined in a package's on_start() function. Package developers should never need to include it or turn it on.

Do I use this functionality if I want to add a 'on_page_save' event using a package?

I'd like to trigger the 'on_page_save' event when a user saves Page Defaults of any page type (Dashboard > Pages & Themes > Page Types > Defaults).

yes, if you look in the Howto's section I just wrote up how to add your own.

I'm looking to create an Add-On that will extend an dashboard page. Would this (or similar code) work to extend a core dashboard page? Or are the events only fired for front-end pages?
