TypeScript FSA utilities for redux-saga 
npm install --save typescript-fsa-redux-saga bindAsyncAction(actionCreators: AsyncActionCreators, options?: BindAsyncActionOptions): HigherOrderSaga
Creates higher-order-saga that wraps target saga with async actions. Resulting saga dispatches started action once started and done/failed upon finish.
skipStartedAction: Set totrueif you want to usestartedaction as a trigger instead of an event. This is useful when usingtakeLatest/takeEveryand you want to avoid having to manually dispatch an extra trigger action. This way, you only have to manually dispatch anstartedaction, and saga will dispatchdone/failedupon finish.
Example:
// actions.ts import actionCreatorFactory from 'typescript-fsa'; const actionCreator = actionCreatorFactory(); // specify parameters and result shapes as generic type arguments export const doSomething = actionCreator.async<{foo: string}, // parameter type {bar: number} // result type >('DO_SOMETHING'); // saga.ts import {SagaIterator} from 'redux-saga'; import {call} from 'redux-saga/effects'; import {doSomething} from './actions'; const doSomethingWorker = bindAsyncAction(doSomething)( function* (params): SagaIterator { // `params` type is `{foo: string}` const bar = yield call(fetchSomething, params.foo); return {bar}; }, ); function* mySaga(): SagaIterator { yield call(doSomethingWorker, {foo: 'lol'}); }
