问题：
I'm going migrate to Redux. 我要迁移到Redux。
My application consists of a lot of parts (pages, components) so I want to create many reducers. 我的应用程序包含很多部分（页面，组件），因此我想创建许多化简器。 Redux examples show that I should use combineReducers() to generate one reducer. Redux示例显示，我应该使用combineReducers()来生成一个reducer。
Also as I understand Redux application should have one store and it is created once the application starts. 另外，据我了解，Redux应用程序应具有一个存储，并且在应用程序启动后即会创建。 When the store is being created I should pass my combined reducer. 创建商店时，我应该通过合并的减速器。 This makes sense if the application is not too big. 如果应用程序不是太大，这是有道理的。
But what if I build more than one JavaScript bundle? 但是，如果我构建多个JavaScript捆绑包怎么办？ For example, each page of application has own bundle. 例如，应用程序的每个页面都有自己的捆绑软件。 I think in this case the one combined reducer is not good. 我认为在这种情况下，一个减速器组合不好。 I looked through the sources of Redux and I have found replaceReducer() function. 我浏览了Redux的源代码，发现了replaceReducer()函数。 It seems to be what I want. 这似乎是我想要的。
I could create combined reducer for each part my application and use replaceReducer() when I move between parts of application. 我可以为应用程序的每个部分创建组合的reducer，并在应用程序的各个部分之间移动时使用replaceReducer() 。
Is this a good approach? 这是一个好方法吗？
