I've been thinking about getting my hands wet with Experience Builder. Coming from WebApp Builder Developer Edition, I like how the node.js is integrated into WAB_DEV. You don't need to install each separately. I'm also working at a Federal site, so the possibility of getting Administrative access to do anything is 'nil to none'. So 3 questions really:
1. Is there a plan to integrate Node.js into Experience Builder?
2. Do you need to "run as administrator" to run Node.js with Experience Builder? (hopefully not as I wont be able to do that where I work).
3. Is the requirement to run node.js version 12.x required?
