Sequential Task Execution in Redux Saga

Illustrate how to execute tasks sequentially using the `yield` keyword in Redux Saga, ensuring one task completes before the next begins.

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

Import necessary effects from redux-saga.

function* fetchUserData(userId) { /* implementation */ }

Define async function to fetch user data.

function* updateUserProfile(profileData) { /* implementation */ }

Define async function to update user profile.

function* sequentialTaskExecutionSaga(action) {

Start of the saga to execute tasks sequentially.

  try {

Try block to handle potential errors in saga execution.

    const userData = yield call(fetchUserData, action.userId);

Call fetchUserData with userId and wait for it to complete.

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

Dispatch an action indicating successful user data fetch.

    const updatedProfile = yield call(updateUserProfile, userData);

Call updateUserProfile with userData and wait for it to complete.

    yield put({ type: 'UPDATE_SUCCESS', updatedProfile });

Dispatch an action indicating successful profile update.

  } catch (error) {

Catch block for handling errors.

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

Dispatch an action indicating the operation failed.

End of the try-catch block.

End of the sequentialTaskExecutionSaga.
