Missing nodemon

[crablab]

Describe the bug
Without nodemon this won't run properly.

Needs nodemon installing as a dev dependency

I'd forgotten about this, but in order to fix this you have to first run npm install locally (outside your docker container)....and then bring your docker services up. I seem to recall that it requires node_modules to exist on the local machine before it brings up the service.
