Sortable Cols with Firebase as Data Source

Having some problems coming up with the code for implementing sortable cols with a Firebase db as the data source. 
- How to designate a Firebase db as a remote datasource ?  I'm using the firebase-collection web component currently. 
- What Vaadin methods should be used to refresh the view?
I would appreciate anyone's help with the topic. 

Some code I'm working with:

Hi Raymond,

The easiest way to use Firebase db as remote datasource is to do it with JavaScript and not with firebase-collection.

You can use 'sort-order-changed' listener for updating the order of the items.

I've used Firebase db + Vaadin grid in one of my projects.

Check function updateReportGrid and this.grid.addEventListener("selected-items-changed"...):
