About

combineWatchers is a simple util, ultra small (0.6 kb gzipped) that helps you organize your saga watchers easily without worrying about the way that you export watchers from your saga files.

type Watchers = GeneratorFunction | GeneratorFunction[]  
const combineWatchers = (...args: Watchers[]): Generator[]

Example

store/sagas/usersSaga.js

import { put, takeLatest } from 'redux-saga/effects';  
import {setUsers, setSelectedUserDetails} from "../actions";  
import {GET_USERS, GET_CURRENT_USER} from "../types";  
import {apiUrl} from "../../config";  
  
const usersEndpoint = '...'  
  
function* fetchUsers() {  
  const users = yield fetch(`${apiUrl}/${usersEndpoint}`).then(res => res.json());  
  yield put(setUsers(users.result))  
}

function* fetchUserDetailInfo(action) {  
  const users = yield fetch(`${apiUrl}/${usersEndpoint}/${action.payload}`).then(res => res.json());  
  yield put(setSelectedUserDetails(users.result))  
} 
  
function* getUsersWatcher() {  
  yield takeLatest(GET_USERS, fetchUsers)  
}
