Firstly, I was missing an `async` here, which somehow still worked for
me then, but produced errors for me when I tried it today.
Then, actually await the promise.
Finally, actually check the target's parent is us, and not just that it
has the attribute!
I don't know what was going on in my head that day. 🤦♂️
Sending a 'closeApp' message allows an app to close a target app, if it
has permission to do so. Currently, permission is granted if the
requesting app is the parent of the target app, or has godmode set.
Send an appClosed message with the instance ID of the app that was
closed. This will be picked up by Puter.js's AppConnection and reported
as a 'close' event.
To make this work, a `data-parent_instance_id` attribute is set on child
app windows. This is very similar to the `data-parent_uuid` attribute,
which tracks parent windows instead of parent app instances. (Dialogs
have a parent window, but are not apps, so don't have a parent app
instance.) The difference is subtle, and we may want to combine these in
the future, but currently closing an app will close any child windows,
which is not behaviour we want for child apps.
This is left open to future additions, by naming it 'locale', and having
the language just be an object field.
Side note, maybe we should have a LocaleService for this?
A broadcast is a message sent to every running app that uses Puter.js.
Broadcasts have a name and a data payload, and are sent as a 'broadcast'
message.
Send a broadcast using:
`globalThis.services.get('broadcast').sendBroadcast(...)`
When doing so, you have the option to keep the broadcast message around,
so that it can be sent to any newly-launched apps. Sending another
broadcast with the same name will overwrite the previous one, so you
don't have to worry about flooding a new app with duplicates.
