Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|module.

Example: Generate a customer component

ng g c customer

Example: Generate a directive: search-box

ng g d search-box

Example: Generate a service: general-data

ng g s general-data

Angular will give out a warning line after this command:

WARNING Service is generated but not provided, it must be provided to be used

After generating a service, we must go to its owning module and add the service to the providers array.

Example: Generate a service and include it in a module automatically

ng g s general-data2 -m app.module

Example: Generate a class, an interface and enum

# class
ng g cl models/customer

# interface
ng g i models/person

# enum
ng g enum models/gender

Example: Generate a pipe

ng g pipe shared/init-caps

Generate a module

Create a login directory and generate a login module in that directory.

ng g module login/login.module

Add/Generate Routing Features

Generate a module called admin and add routing feature to it.

ng g module admin --routing
