链式减速器ngrx

我有功能缩减器,例如: LoadReducer ,则, DeleteReducer 和 CreateReducer 。所有这些都只是简单的减速机。(还有一个名为namedReducer的高阶减速机

export function namedReducer(reducerName: string) {
    return (reducer: Function) => {
        return function newReducer(state, action) {
            const { name } = action;
            const isInitializationCall = state === undefined;
            const shouldRunWrappedReducer = reducerName === name || isInitializationCall;
            return shouldRunWrappedReducer ? reducer(_.get(state, reducerName), action) : state;
        };
    };
}

我想在appstate中创建子状态,它使用我的特性缩减器的子集。例如:

应用状态:

{
  bananaState: namedReducer('banana')(/* here chaining together CreateReducer and LoadReducer */),
  appleState: namedReducer('apple')(/* here chaining together LoadReducer, DeleteReducer */) 
}

当我发出一个动作时 {name: 'banana', type: 'Load'} 它会碰到香蕉减速机。这方面有什么模式或建议吗?我试过了 compose 还有 combineReducers 但是没有运气。我错过了什么。是否有将功能链接在一起的工具。

非常感谢。
