Answer 1

To handle async operation challenges in React with redux-saga:

Install redux-saga:

npm install redux-saga

Create Saga Middleware:

import createSagaMiddleware from 'redux-saga';

const sagaMiddleware = createSagaMiddleware();

Configure Store:

import { createStore, applyMiddleware } from 'redux';

import rootReducer from './reducers';

import rootSaga from './sagas';

const store = createStore(rootReducer, applyMiddleware(sagaMiddleware));

sagaMiddleware.run(rootSaga);

Write Saga for Async Call:

import { call, put, takeLatest } from 'redux-saga/effects';

function* fetchDataSaga() {

  try {

    const response = yield call(fetch, 'https://api.example.com/data');

    const data = yield response.json();

    yield put({ type: 'FETCH_SUCCESS', payload: data });

  } catch (error) {

    yield put({ type: 'FETCH_FAILURE', payload: error });

  }

}

export default function* rootSaga() {

  yield takeLatest('FETCH_REQUEST', fetchDataSaga);

}
