Angular Component Providers

Share This Post

As you build your application, you will create services. An Angular component is to contain logic for the view, while services contains logic for the component. For example, a call to an API to get data is one example a job that a services performs. This is where providers come in.

Services get injected into a component to give the component access to the functionality the service provides. There are a couple of ways to inject the service into the application component.

In the provider array…

  declarations: [
  imports: [
  providers: [

You can also import it into the component itself…

// Import service
import { DataService } from '../Services/data.service';
// Place import in constructor variable
// Can use dataService variable in code
    private dataService : DataService
  ) {

You will find yourself doing this a ton in your Angular apps. So it will probably become second nature to you.

Happy Coding!
