geRx is the data and state storage of your application, built on top of RxJs. The main advantage is ease of use.
geRx provides features for implementing onPush and onPull strategies, tracking request status, calling the application service method from anywhere.
app.module.ts
import { GeRx } from 'geRx';
@NgModule({
[...]
providers: [GeRx],
[...]
})
export class AppModule {}
app.service.ts
export class AppService {
hello(): Observable<any> {
return of({message: 'Test geRx'}).pipe(delay(3000));
}
edit(text: string): Observable<any> {
return of({message: text}).pipe(delay(3000));
}
}
app.component.ts
@Component({
selector: 'test-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss'],
changeDetection: ChangeDetectionStrategy.OnPush
})
export class TestComponent implements OnInit, AfterViewInit {
public entityName = 'hello';
constructor(public geRx: GeRx, private appService: AppService) {}
ngOnInit(): void {
const geRxMethods: GeRxMethods = {
show: this.appService.hello.bind(this.appService),
edit: this.appService.edit.bind(this.appService)
};
return this.geRx.addEntity(this.entityName, geRxMethods);
}
ngAfterViewInit(): void {
this.geRx.show(this.entityName);
}
onEdit(text): void {
this.geRx.edit(this.entityName, text);
}
onClear(): void {
this.geRx.cleanEntity(this.entityName);
}
}
app.component.html
