redux-saga-loading

store loading state with redux.

---

Install

$ npm install redux-saga-loading --save

Usage

store.js

import { createStore, combineReducers, applyMiddleware } from 'redux';
import { createReduxSagaLoading } from 'redux-saga-loading'

const loading = createReduxSagaLoading()
const rootReducer = combineReducers({
  ...reducers,
  ...loading.reduxReducers
});

export const store = createStore(
  rootReducer,
  applyMiddleware(thunk, sagaMiddleware)
)

saga.js

import { call, put } from "redux-saga/effects";
import { api } from 'apis'
import { startLoading, stopLoading } from 'redux-saga-loading'

function* list(action: any) {
  try {
    yield startLoading('users', 'rooms')
    const users = yield call(api.getUsers);
    const rooms = yield call(api.getRooms);
    yield put({ type: "SET_USERS", users });
    yield put({ type: "SET_ROOMS", rooms });
  } catch (error) { } finally {
    yield stopLoading('users', 'rooms')
    // or yield stopAllLoading()
  }
}

Then we can access loading state from store.
