Hi people of Gaia,

A quick update about marionette and the way it operates on elements that are part of the ShadowDOM. 

Marionette JS client now supports stepping in and out of ShadowRoot similar to how it performs navigation to and from frames. There’s no need any more to run JS script on the marionette server side to manipulate or get something out of ShadowDOM. See example from the integration test:


Cheers,

That's great.

I have one major hurdle / question that I don't find a solution in
reading the inline doc or the source code.

How do you move out of the shadowroot?

Ah, so the way you get out of it is by just calling:

client.switchToShadowRoot() with no arguments,  sorry, I should’ve mentioned it. It will either step into parent shadowRoot (if it’s nested) or into the main content.
