# AppEvents

The AppEvent system in Discourse provides a pub/sub mechanism for handling UI updates and component interactions - and these events are triggered via calls of `AppEvent.trigger`.

This topic consolidates a list of all such event triggers and their arguments, along with line-of-code references to the Discourse source code.

## How to figure out what happens on an event trigger

AppEvent is based on the Ember’s Evented class, and similarly, events are handled by [the `on` method](https://api.emberjs.com/ember/5.12/classes/Evented/methods/on?anchor=on).

Once the specific AppEvent trigger is identified, you may search in the source code for the corresponding `.on` method with the event name as the first argument.

This method should have an event handler function passed in as the last argument for executing any necessary logic upon trigger of the event.

Taking the `composer:open` event, we can search for `appEvents.on("composer:open"`. This could lead us to 1 or more places in the code where the event is handled. Each of these would execute a callback function whenever the event is triggered, for example:

```plaintext
    this.appEvents.on("composer:opened", this, this._findMessages);

```

You would then refer to the definition of the callback function `this._findMessages` to understand what happens when the `composer:opened` event is triggered. This callback function can take in arguments passed in from the trigger of the event to be processed within the scope of the function.
