Why no Angular-CLI generate command for 'model' in Angular Project?

While learning up Angular I just went through the various Angular-CLI commands to generate individual parts of Angular like 'Component', 'Services', 'Interface', 'Pipes', etc.

Generating Angular Items via Angular-CLI

ng g c components/comp-1 //generates component
ng g s services/service-1 // generates service
ng g i interfaces/interface-1 // generates interface

But, I am amazed why there is no generate command for 'Model' (though Interface also does nearly some work -- but model is more powerful as can contain methods also in Class).

Am I missing something or Team-Angular missed on generating a command for 'automatically generating Models' -- as they are at the very core of OOPS Framework.

Because a model is a class, to generate it use --type option like this:

ng generate class hero --type=model

will result in:

hero.model.ts

You cannot generate a model directly. Actually model is a class. ng generate allows only following types to generate by default.

  1. appShell
  2. application
  3. class
  4. component
  5. directive
  6. enum
  7. guard
  8. interface
  9. library
  10. module
  11. pipe
  12. service
  13. serviceWorker
  14. universal
  15. webWorker

So in your case you can use --type option to define a generate classes. Let's assume you want a class like bar.foo.ts

You just have to define it with following option.

ng generate class bar --type=foo

in your case you can define a module with this command

ng generate class nameOfYourModule --type=model

It will generate nameOfYourModule.model.ts

Please refer this official documentation of ng generate options for more informations.

This command also generate model

ng generate class employee --type

Result In:

employee.ts employee.spec.ts

I just use ng generate class (without any flags), and I believe many others do as well. I think the only time I use a pure class file in Angular is with models. Since they are mostly in the models folder, there's little reason to add additional suffix of 'model' by using --type=model. I believe that's part of the reasons why the Angular team did not include the 'ng generate model' command (since it is duplicative of class).

Just run in root of project:

ng generate interface your_model_name --type=model
# or in models folder
ng generate interface models/your_model_name --type=model
小开 
ng g class subfolder/yourclass --type=model --skip-tests

will create a class yourclass in app\subfolder. If you remove --skip-tests, you will get an extra file yourclass.model.spec.ts.
