In this video, we cover how to generate services using the Angular CLI. To generate a service, you need to run the following command:
ng generate service service-name
You can add a number of flags after the component name, depending on what you need. The flags we covered in this section are:
Remember that when generating services with the CLI, modules will not be updated. That's because in the latest versions of Angular, services have a setting that is added to the decorator on a service that makes the service be provided in a location of the application. By default, that location is "root". That's the preferred method of creating services, so when you add a service to a folder it's done for organization of code only. Don't expect to see modules updated after adding a new service.
For more information on generating services, and for a list of all the flags available when generating services, you can check out the docs.
