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();
