Short demo , around 10 min, about the new experimental Components feature in PowerApps.
This opens up the ability to create a components library that can be reused across all of your PowerApps.
I also briefly talk about passing in parameters from a React app to your PowerApp. You could use this technique to pass in configuration data for your PowerApp based on a particular scenario such as demoed in the video, a People Viewer control to show the Department Head and all their direct reports.
