是否可以联合Reducer的ActionCreators？

Question

我想加入一些做完全相同事情的“on()”，从而节省代码行，这可能吗？

给出我的代码示例：

const peopleReducer = createReducer(
    INIT_STATE,
    on(fromPeopleAction.GET_ALL_SUCCESS, (state, { peoples }) => adapter.addMany(peoples, { ...state, loading: false })),
    on(fromPeopleAction.GET_ALL_FAIL, (state, { error }) => ({ ...state, error, loading: false })),
    on(fromPeopleAction.CREATE_SUCCESS, (state, { people }) => adapter.addOne(people, { ...state, loading: false })),
    on(fromPeopleAction.CREATE_FAIL, (state, { error }) => ({ ...state, error, loading: false })),
    on(fromPeopleAction.DELETE_SUCCESS, (state, { id }) => adapter.removeOne(id, { ...state, loading: false })),
    on(fromPeopleAction.DELETE_FAIL, (state, { error }) => ({ ...state, error, loading: false }))
);

请注意，我们有一些“on()”做同样的事情，是否可以为同一个 on() 调用多个操作？

Answer 1

根据 on's overloads 判断，如果您这样做，我认为您可以对多个操作使用相同的逻辑：

on(action1, action2, action3, ...action10, (state, action) => {})

请注意，在 10 actions 之后，您将丢失类型。

同样重要的是要注意最后一个参数应该是reducer。
