### Redux

本节提供对 Redux 设置的访问以及覆盖 Redux 方法的选项。

#### initialState

```javascript
init({
  redux: {
    initialState: any
  }
 })
```

你的 app 的 initialState. 这可能不是必需的，因为 model 的状态会覆盖 init state 。

#### reducers

```javascript
const someReducer = (state, action) => {
  switch(action.type) {
    default:
      return state
  }
}

init({
  redux: {
    reducers: {
      someReducer,
    }
  }
})
```

允许传递 reducer functions，而不是 model 。 虽然不推荐，但可用于迁移 Redux 代码库或配置不同的 Redux 扩展。

#### middlewares

```javascript
init({
  redux: {
    middlewares: [customMiddleware()]
  }
})
```

添加 middleware 到你的 store.

#### enhancers

```javascript
init({
  redux: {
    enhancers: [customEnhancer()]
  }
})
```

添加 enhancers 到你的store.

#### rootReducers

```javascript
init({
  redux: {
    rootReducers: {
      'RESET': (state, action) => undefined,
    }
  }
})
```

一种在你的 root reducer 基础上设置中间件钩子的方法， 与中间件不同，返回值是下一个状态。如果**`undefined`**，这个 state 将会退回到 reducers 的初始 state.

#### combineReducers

```javascript
init({
  redux: {
    combineReducers: customCombineReducers
  }
})
```

允许访问覆写 Redux 的 `combineReducers` 方法。对于当前设置 Redux persist v5 来说是必须的。

#### createStore

```javascript
init({
  redux: {
    createStore: customCreateStore
  }
})
```

允许访问覆写 Redux 的 `createStore` 方法。对于基于 Redux 设置 Reactotron 来说是必须的。

#### devtoolOptions

```javascript
init({
  redux: {
    devtoolOptions: customDevtoolOptions
  }
})
```

访问 [redux devtool options](https://github.com/zalmoxisus/redux-devtools-extension/blob/master/docs/API/Arguments.md) .在 [devtool recipes](https://rematch.gitbooks.io/rematch/docs/recipes/devtools) 之上了解更多配置 devtools 的信息。
