Mochi has a CLI, albeit, it's not tested much. Use at your own risk.
Note: I use it. Most commands just add a controller and/or a migration with
authbeing the heaviest. Nothing crazy. The cli outputs all files that were created/modified so it's pretty easy to check as well.
The cli follows
mochi g template class_name orm so
mochi g auth user granite generates the auth template with
User as the class name and granite is the orm you are using.
