-Due to using a single state tree, all state of our application is contained inside one big object. However, as our application grows in scale, the store can get really bloated.
+# Modules
 
-To help with that, Vuex allows us to divide our store into **modules**. Each module can contain its own state, mutations, actions, getters, and even nested modules - it's fractal all the way down:

-### Namespacing
+### 命名空间
 
-Note that actions, mutations and getters inside modules are still registered under the **global namespace** - this allows multiple modules to react to the same mutation/action type. You can namespace the module assets yourself to avoid name clashing by prefixing or suffixing their names. And you probably should if you are writing a reusable Vuex module that will be used in unknown environments. For example, we want to create a `todos` module:
+要注意，模块内的 actions、mutations 以及 getters 依然注册在**全局命名空间**内 —— 这就会让多个模块响应同一种 mutation/action 类型。你可以在模块的名称中加入前缀或者后缀来设定命名空间，从而避免命名冲突。如果你的 Vuex 模块是一个可复用的，执行环境也未知的，那你就应该这么干了。距离，我们想要创建一个 `todos` 模块：

-### Dynamic Module Registration
+### 注册动态模块
 
-You can register a module **after** the store has been created with the `store.registerModule` method:
+你可以用 `store.registerModule` 方法在 store 创建**之后**注册一个模块：
 
 ``` js
 store.registerModule('myModule', {
   // ...
 })
 ```
 
-The module's state will be exposed as `store.state.myModule`.
+模块的 `store.state.myModule` 暴露为模块的状态。
 
-Dynamic module registration makes it possible for other Vue plugins to also leverage Vuex for state management by attaching a module to the application's store. For example, the [`vuex-router-sync`](https://github.com/vuejs/vuex-router-sync) library integrates vue-router with vuex by managing the application's route state in a dynamically attached module.
+其他的 Vue 插件可以为应用的 store 附加一个模块，然后通过动态注册就可以使用 Vuex 的状态管理功能了。例如，[`vuex-router-sync`](https://github.com/vuejs/vuex-router-sync) 库，通过在一个动态注册的模块中管理应用的路由状态，从而将 vue-router 和 vuex 集成。
 
-You can also remove a dynamically registered module with `store.unregisterModule(moduleName)`. Note you cannot remove static modules (declared at store creation) with this method.
+你也能用 `store.unregisterModule(moduleName)` 移除动态注册过的模块。但是你不能用这个方法移除静态的模块（也就是在 store 创建的时候声明的模块）。

-Vuex doesn't really restrict how you structure your code. Rather, it enforces a set of high-level principles:
+实际上，Vuex 在怎么组织你的代码结构上面没有任何限制，相反，它强制规定了一系列高级的原则：
 
-1. Application-level state is centralized in the store.
+1. 应用级的状态集中放在 store 中。
 
-2. The only way to mutate the state is by committing **mutations**, which are synchronous transactions.
+2. 改变状态的唯一方式是提交**mutations**，这是个同步的事务。
 
-3. Asynchronous logic should be encapsulated in, and can be composed with **actions**.
+3. 异步逻辑应该封装在**action** 中。
 
-As long as you follow these rules, it's up to you how to structure your project. If your store file gets too big, simply start splitting the actions, mutations and getters into separate files.
+只要你遵循这些规则，怎么构建你的项目的结构就取决于你了。如果你的 store 文件非常大，仅仅拆分成 action、mutation 和 getter 多个文件即可。
