How to handle async form submissions in React using redux-saga

Question

With the help of code can you tell me How to handle async form submissions in React using redux-saga?

Answer 1

To handle async form submissions in React using redux-saga, follow these precise steps:

1. Dispatch Form Submission Action

Trigger an action from your component on form submission:

dispatch({ type: 'SUBMIT_FORM_REQUEST', payload: formData });

2. Create Saga to Handle Side Effects

In your saga:

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

import { submitFormAPI } from './api';

function* handleFormSubmit(action) {

  try {

    const response = yield call(submitFormAPI, action.payload); // call API

    yield put({ type: 'SUBMIT_FORM_SUCCESS', payload: response }); // success action

  } catch (error) {

    yield put({ type: 'SUBMIT_FORM_FAILURE', payload: error.message }); // failure action

  }

}

export function* watchFormSubmit() {

  yield takeLatest('SUBMIT_FORM_REQUEST', handleFormSubmit);

}

3. Connect Saga to Redux Store

Run your saga using redux-saga middleware in the store setup.
