can redux saga dispatch return result immediately instead of returning action

[alanhg]

maybe like this

 async componentDidMount() {
        const userInfo = await this.props.fetchUserAction();
    }

function* fetchUserEffects() {
    console.log('fetchUserEffects');
    const user = (yield call(getUserInfo));
    return user;
    // yield put({type: 'USER_FETCH_SUCCEEDED', user: user.data});
}

function* mySaga() {
    yield takeEvery('USER_FETCH', fetchUserEffects);
    yield takeEvery('TEST_SAGA', testSagaEffects);
}

export default mySaga;

export const fetchUserAction = () => ({
    type: 'USER_FETCH'
});

benefit

I can use the effect's result directly, don't need to put action and save data to redux store.

dva.js

According to my understanding, dva.js is based on the framework of redux-saga and other technologies. When we dispatch the action in this framework and execute saga-effects, we can get the result directly. I think this is a very good feature.

You don't call saga directly, you actually call store.dispatch(action).

You don't call saga directly, you actually call store.dispatch(action).

I know it.

Then what is your question about ? You can use something like https://github.com/Chion82/redux-wait-for-action this in order to achieve this behavior but you should not build your app in that way.

Hey @alanhg

I needed the same behavior once so I wrote my own helper functions to do that. It also enables waiting for the result of dispatched actions in saga. Take a look at redux-saga-callback.

@kutlugsahin I will try.
