yield all (parallel requests) into queue in redux saga?

Question

I have sagas:

function* sagaA() {         // accumulates all user requests
   // do stuff
   yield all(users.map((user) => call(sagaB, user));
   yield put(SUCCESS ACTION);
}

function* sagaB(user) {     // is responsible for single request
   yield call(api, user);
   // do stuff
}

function* watch() {       // watches for the action
   yield take('REQUEST', sagaA);
}

However, in this case the requests are parallel, they are not queued.

Question: how to modify this sagas so they are being called one by one?

Answer 1

You can use regular for loop:

function* sagaA() {
  for(const user of users) {
    yield call(sagaB, user);
  }
  yield put(SUCCESS_ACTION);
}
