What would be the best way to icorprate the Slider bar into my app?
You will need to create a plugin. You have a choice of writing one from scratch, or wrapping one from npm and writing the values into a Neonto dataslot or datasheet.
At this moment I do not have a good tutorial for either of these two options. I do have a tutorial that discusses reading from Neonto data structures into a wrapped plug (attached) and you can go to the plugin store, and download Camera and Rating to look at.
Camera demonstrates how to write your own plugin from scratch, and Rating demonstrates how to save into a dataslot (via the Interactions pane) from a wrapped npm component.
I hope this helps,
