Rather I complained too soon.
I was able to figure out the routing issue and get the voice commands fixed in the Angular (6) app. So no more working with the previous application.
I’m now attempting to install opencv4nodejs on Windows (main) instead of WSL so I can run the app there.
I don’t know why my multiple router files didn’t work so that’s for another day.
Tomorrow, I’ll hope my HUD goggles arrive for testing. And I’ll work on my plugin concept a bit while working on opencv4nodejs hooks so I can have a base framework for my calls.
