// Have something async to run.
const fetchStuff = () => fetch('https://unsplash.it/list').then(r => r.json())
 
// Run it with Redux Saga.
function* mySaga() {
  yield request(FETCH_STUFF, [fetchStuff])
}
 
// Do stuff easily in your reducers.
const stuffReducer = (state = {}, { type, payload }) => {
  switch (type) {
    case FETCH_STUFF.STARTED:
      return {
        ...state,
        // Maybe use this to show a loading spinner?
        fetching: true,
      }
    case FETCH_STUFF.SUCCEEDED:
      return {
        ...state,
        fetching: false,

    case FETCH_STUFF.ERRORED:
      return {
        ...state,

      }
    default:
      return state

Advanced Usage

• You can pass arguments to your async function.
• You can attach metadata to all request actions to keep them associated.

function* mySaga() {
  yield request(
    FETCH_STUFF,
    [fetchStuff, fetchStuffArg],
    { fetchStuffMeta: 'META' }
  )
}
