reducer 和 saga 的顺序

Question

当调度一个动作时，它到达减速器时的顺序是什么？保证传奇？

我可以依靠它吗

首先进入reducer
然后是传奇？

减速器：

 function reducer(state, action) {

    switch (action.type) {
       case 'MY_ACTION':
       // decorate action so that an epic doesn't have to take data from store
       action.ports = state.itemsModified;                 
       return state;
     }
    }

传奇：

export function* sagaUpdatePorts() {
    yield* ReduxSaga.takeEvery(actions.GRID_PORTS_ASYNC_UPDATE_PORTS, updatePorts);
}

function* updatePorts(action) {
    const {response, error} = yield SagaEffects.call(portsService.updatePorts, action.ports);
}

Answer 1

是的。该动作首先击中 reducer，然后击中 Sagas。
