API.Fetch Saga - Javascript

API.Fetch Saga is a middleware for managing side effects in redux-saga. It allows you to handle API calls in a clean and efficient way.

How it works

When using API.Fetch Saga, you create a saga that listens to a specific action. When that action is dispatched, the saga uses yield call to execute a function that makes an API call. If the call is successful, the saga dispatches a new action with the fetched data. If the call fails, the saga dispatches an error action.

Here's an example saga that listens to a FETCH_USERS action:

import { call, put, takeEvery } from 'redux-saga/effects';
import { fetchUsersApi } from '../api';
import { fetchUsersSuccess, fetchUsersFailure } from '../actions';

function* fetchUsersSaga() {
  try {
    const users = yield call(fetchUsersApi);
    yield put(fetchUsersSuccess(users));
  } catch (error) {
    yield put(fetchUsersFailure(error));
  }
}

export default function* watchFetchUsers() {
  yield takeEvery('FETCH_USERS', fetchUsersSaga);
}

In this example, fetchUsersApi is a function that makes the actual API call. fetchUsersSuccess and fetchUsersFailure are action creators that dispatch success and error actions, respectively.

Benefits of using API.Fetch Saga

Using API.Fetch Saga has several benefits:

• Allows you to handle API calls in a clean and efficient way.
• Handles error scenarios gracefully, dispatching an error action that you can handle in your reducers.
• Allows for easy testing of sagas since they are just functions that return generator objects.
• Works great with other redux-saga effects such as put, takeEvery, select, and more.

Conclusion

If you're looking for a clean and efficient way to handle API calls in your redux-saga middleware, API.Fetch Saga is a great option. It allows you to handle API calls in a graceful way and integrates well with other redux-saga effects.
