You need to create epic using RxJS operators. This epic will listen to event ping, wait for 1 second and map them to a new event, pong
epic.jsimport { combineEpics, ofEvent, toEvent } from 'storeon-observable'
import { mapTo, delay } from 'rxjs/operators'
const epic = event$ => event$.pipe(
ofEvent('ping'),
delay(1000),
mapTo(toEvent('pong')),
);
export const epics = combineEpics(epic);
Create store and pass epics to the createEpicModule function. It will connect all epics to the Storeon using the storeon-observable middleware
store.jsimport { createStoreon } from 'storeon'
import { createEpicModule } from 'storeon-observable'
import { epics } from './epic';
let increment = store => {
store.on('@init', () => ({ isPinging: false }))
store.on('ping', () => ({ isPinging: true }))
store.on('pong', () => ({ isPinging: false }))
}
export const store = createStoreon([increment, createEpicModule(epics)]);
Using TypeScript you can assign Epic interface to the function to specify action and state typing
epic.tsimport { combineEpics, ofEvent, Epic, toEvent } from 'storeon-observable';
import { mapTo, delay } from 'rxjs/operators'
interface State {
isPinging: boolean;
}
interface Events {
ping: undefined;
pong: undefined;
}
const epic: Epic<State, Events> = (event$, state$) => event$.pipe(
ofEvent('ping'),
delay(1000),
mapTo(toEvent('pong')),
);
export const epics = combineEpics(epic);
This module based on redux-observable.
