Angular tutorial - Services | Learn angular 9 Services - [2020] | Create services using angular CLI
In this video we will try to learn about angular services.
We will see how we can create angular services with the help of angular CLI. We will also create some object in service and a method to fetch those array of object with the help of public function in the service. We will create a new component that will utilize the angular created services. We will also tell about the benefit of using the services. If we have multiple components in the angular application then instead of creating the data on the each component we will try to show how we can create a single service that will be responsible to create and give data to the components. We will also see how dependency injection works in angular.With the help of dependency injection we will try to inject service to the component and use the service methods. We will create the service with angular CLI using command 'ng g s serviceName'.
Also we will get to know how it is useful to create and use service as well as for your project functionality and for writing the unit test.
