Example

import {switchMap} from 'rxjs';
import {state, emitter, namedGroup, transmit} from '@bitfiber/rx';
 
// Defines a named group that contains emitters, states, or other groups
const myGroup = namedGroup(
  {
    launch: emitter<void>(),
    data: state<number>(0),
  },
  ({launch, data}) => {
    // Add interaction logic inside the 'onInit' callback
    launch
      // Performs an effect each time the launch emits new data
      .effect(switchMap(() => getData('api/data').pipe(transmit(data))));
  }
);
 
// Initializes the group and all items it contains
myGroup.initialize();
 
// Launches data loading
myGroup.launch.emit();
 
// Completes the group, finalizing all its items
myGroup.complete();
