-For Custom elements, we will later introduce a way to replace *Callback
syntax with dde:*
events. The on.*
functions then listen to the appropriate Custom Elements events (see Custom element lifecycle callbacks | MDN).
But, in case of regular elemnets the MutationObserver
| MDN is internaly used to track these events. Therefore, there are some drawbacks:
- To proper listener registration, you need to use
on.*
not `on("dde:*", …)`! - Use sparingly! Internally, library must loop of all registered events and fires event properly. It is good practice to use the fact that if an element is removed, its children are also removed! In this spirit, we will introduce later the host syntax to register clean up procedures when the component is removed from the app.
# Final notes
The library also provides a method to dispatch the events.

| MDN is internaly used to track these events. Therefore, there are some drawbacks:
- To proper listener registration, you need to use
on.*
not `on("dde:*", …)`! - Use sparingly! Internally, library must loop of all registered events and fires event properly. It is good practice to use the fact that if an element is removed, its children are also removed! In this spirit, we will introduce later the host syntax to register clean up procedures when the component is removed from the app.
To provide intuitive behaviour, similar also to how the life-cycle events works in other frameworks/libraries, deka-dom-el library ensures that on.connected
and on.disconnected
are called only once and only when the element is (dis)connected to live DOM. The solution is inspired by Vue. For using native behaviour re-(dis)connecting element, use:
- custom
MutationObserver
or logic in (dis)
or… - re-add
on.connected
or on.disconnected
listeners.
# Final notes
The library also provides a method to dispatch the events.
