Service 
Modules can individually provide their own Services
Create Service 
1. Cli command 
bash
$ vona :create:bean service menu --module=home-base2. Menu command 
TIP
Context Menu - [Module Path]: Vona Create/Service
Use Service 
The Service of the module can be obtained through the Scope instance
For example, we use the Service menu provided by thie module home-base inside the current module:
typescript
class ControllerMenu {
  retrieveMenus() {
    return this.scope.service.menu.retrieveMenus('');
  }
}Use Service cross-module 
For example, we use the Service menu provided by thie module home-base inside the module home-index:
typescript
class ControllerHome {
  index() {
    return this.$scope.homeBase.service.menu.retrieveMenus('');
  }
}
