Generate a routing module while creating a module in angular-cli
I was searching about this a bit and found some article which has a very good explanation for different kind of commands.
The Ultimate Angular CLI Reference
So basically, there's no separate command to create routing.module file. But, that can be created while on the creation of the module
ng g module [module-name] --routing
or ng g m [module-name] --routing
will create the module and add the mappings/metadata linkings.
Creates both module and routing simultaneously in the same folder.
ng g m sub-folder/module-name --routing
Creates the only module.
ng g m sub-folder/module-name
