Check out the thread on uibuilder/VueJS components as well. Managed to squeeze in some experiments and the experimental module listed is beginning to show how I'll add some "magic" to uibuilderfe that means you only need to supply some very simple HTML containing a suitably built component and then send through some standardised data from Node-RED to control things, no JavaScript of your own needed and no messing with attibs/props in the HMTL. All you need to do is add a ref id.
