The article discusses the significance of design patterns in Angular, particularly emphasizing the Singleton pattern for implementing services. This pattern allows a service to be instantiated once and shared across various components, improving data communication and application structure. Key implementation steps include creating a service with Angular CLI, adjusting its `@Injectable` decorator with the `providedIn: 'root'` property, and injecting the service into components for shared access to its functionalities. These practices contribute to building modular, maintainable, and scalable applications.
In Angular, the Singleton pattern helps in creating services that are instantiated only once and shared across components, facilitating communication and data sharing.
To implement a Singleton service in Angular, use 'providedIn' property for easy access throughout the application as demonstrated by MySingletonService.
