Service
Overview
The Service is a layer that facilitates communication between the application components and the NGRX store. It extends StoreServiceBase from @k5cjs/store, providing a structured way to manage state interactions.
Defining the Service
The Users Service is responsible for dispatching actions and selecting state data using predefined selectors.
Example Service Definition
typescript
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { StoreServiceBase } from '@k5cjs/store';
import { actions } from './users.actions';
import { selectors } from './users.selectors';
import { User } from './users.type';
@Injectable({ providedIn: 'root' })
export class UsersService extends StoreServiceBase<User> {
constructor() {
super(actions, selectors);
}
}import { Injectable } from '@angular/core';
import { Observable } from 'rxjs';
import { StoreServiceBase } from '@k5cjs/store';
import { actions } from './users.actions';
import { selectors } from './users.selectors';
import { User } from './users.type';
@Injectable({ providedIn: 'root' })
export class UsersService extends StoreServiceBase<User> {
constructor() {
super(actions, selectors);
}
}See Also:
users.actions.ts– Defines actions that trigger state changes.users.selectors.ts– Provides efficient state retrieval.
Explanation
- Extends
StoreServiceBase<User>– Inherits built-in CRUD functionalities for handling store actions. - Uses predefined
actions– These actions trigger state updates. - Uses predefined
selectors– Enables efficient state queries.
Using the Users Service
The Users Service simplifies store interactions within Angular components and other services.
Conclusion
By extending StoreServiceBase, the Users Service provides a structured and reusable way to manage the state layer.
