Services and Dependency Injection

Services contain reusable business logic. Angular uses Dependency Injection (DI) to provide services to components.

Why Services?

  • Share data between components
  • API calls
  • Business logic
  • State management

Create a Service

ng generate service user

Inject Service

constructor(private userService: UserService) {}

Using Service

this.userService.getUsers();
