3、集成 immutable.js

此项目除了依赖包要配置之外,只有 redux 下的 reducer 相关文件会设置成 immutable.js 普通的 react 组件我没有设置成 immutable.js

App.js

import {ConnectedRouter} from "connected-react-router";
// 换成
import {ConnectedRouter} from "connected-react-router/immutable";

store->index.js

import {routerMiddleware} from "connected-react-router";
// 换成
import {routerMiddleware} from "connected-react-router/immutable";
// 添加
import immutableTransform from "redux-persist-transform-immutable";

const persistConfig = {transforms: [encryptor],
  // 换成
  transforms: [immutableTransform()
    // 注意:必须要注释 encryptor 否则会报错
    // encryptor
  ],
  ...
}

redux->reducers->index.js

import {connectRouter} from "connected-react-router";
// 换成
import {connectRouter} from "connected-react-router/immutable";

redux->reducers->authReducer.js

// 添加
import {Map, fromJS, merge} from "immutable";

const initState = {
  user: null,
  token: ""
};

[authTypes.AUTH_SUCCESS]: (state, action) => {return Object.assign({}, state, {user: action.data.user, token: action.data.token});
    },
    [authTypes.SIGN_OUT]: (state, action) => {return Object.assign({}, state, {
        user: null,
        token: ""
      });
    }
// 换成
const initState = fromJS({
  user: null,
  token: ""
});

    [authTypes.AUTH_SUCCESS]: (state, action) => {
      return state.merge({
        user: action.data.user,
        token: action.data.token
      });
    },
    [authTypes.SIGN_OUT]: (state, action) => {
      return state.merge({
        user: null,
        token: ""
      });
    }

redux->reducers->layoutPageReducer.js

// 添加
import {Map, fromJS, merge, List} from "immutable";

const initState = {
  index: "126",
  subIndex: "",
  collapsed: false,
  menus: [],
  loading: false
};
[layoutPageTypes.SAVE_MENU_INDEX]: (state, action) => {const { keyPath} = action.payload;
      let index = keyPath[0];
      let subIndex = null;
      if (keyPath.length === 2) {subIndex = keyPath[1];
      }
      return Object.assign({}, state, {
        index: index,
        subIndex: subIndex
      });
    },
    [layoutPageTypes.SAVE_MENU_COLLAPSED]: (state, action) => {const { collapsed} = action.payload;
      return Object.assign({}, state, {collapsed: collapsed});
    },
    [layoutPageTypes.GET_MENUS]: (state, action) => {const { menus} = action;
      return Object.assign({}, state, {menus: menus});
    }
// 换成
const initState = fromJS({
  index: "126",
  subIndex: "",
  collapsed: false,
  menus: List()});

[layoutPageTypes.SAVE_MENU_INDEX]: (state, action) => {const { keyPath} = action.payload;
      let index = keyPath[0];
      let subIndex = null;
      if (keyPath.length === 2) {subIndex = keyPath[1];
      }
      return state.merge({
        index: index,
        subIndex: subIndex
      });
    },
    [layoutPageTypes.SAVE_MENU_COLLAPSED]: (state, action) => {const { collapsed} = action.payload;
      return state.merge({collapsed: collapsed});
    },
    [layoutPageTypes.GET_MENUS]: (state, action) => {const { menus} = action;
      return state.merge({menus: menus});
    }

middleware->authTokenMiddleware.js

// 添加
import {fromJS} from "immutable";

if (action.type === REHYDRATE) {if (action.payload && action.payload.authReducer && action.payload.authReducer.token) {ApiRequest.setToken(action.payload.authReducer.token);
    }
  }
// 换成
if (action.type === REHYDRATE) {if (typeof action.payload !== "undefined") {
      let authReducer = action.payload.authReducer;
      if (authReducer) {const token = authReducer.get("token");
        ApiRequest.setToken(token ? token : null);
      }
    }
  }

components->layout->LayoutPage.js

<span style={{marginLeft: 8}}>{authReducer.user ? authReducer.user.name : "用户"}</span>

<Switch>{authReducer.token ? renderRoutes(routes) : <Redirect to="/login" />}</Switch>
// 换成
<span style={{marginLeft: 8}}>{authReducer.get("user") ? authReducer.getIn(["user", "name"]) : "用户"}</span>

<Switch>{authReducer.get("token") ? renderRoutes(routes) : <Redirect to="/login" />}</Switch>

components->layout->SideMenu.js

let menus = layoutPageReducer.menus;

<Menu
          theme="light"
          defaultSelectedKeys={[layoutPageReducer.index]}
          selectedKeys={[layoutPageReducer.index]}
          defaultOpenKeys={[layoutPageReducer.subIndex]}
          mode="inline"
          className="sider-menu-container"
          inlineCollapsed={layoutPageReducer.collapsed}
          onClick={this.clickSidebarMenu}
        >
          {newMenus}
        </Menu>
// 换成
let menus = layoutPageReducer.get("menus");

        <Menu
          theme="light"
          defaultSelectedKeys={[layoutPageReducer.get("index")]}
          selectedKeys={[layoutPageReducer.get("index")]}
          defaultOpenKeys={[layoutPageReducer.get("subIndex")]}
          mode="inline"
          className="sider-menu-container"
          inlineCollapsed={layoutPageReducer.get("collapsed")}
          onClick={this.clickSidebarMenu}
        >
          {newMenus}
        </Menu>

components->layout->AppRoute.js

Authentication() {return this.props.store.authReducer.token ? <Redirect to="/" /> : <Login />;}
// 换成
    return this.props.store.authReducer.get("token") ? <Redirect to="/" /> : <Login />;

4、启动项目看是否集成成功

命令行运行:yarn start

清除下缓存尤其是 localstorage,如果看到上面的登录页面那么恭喜你配置成功!

5、redux-logger 打印 immutable.js 日志

下面我们来看看 redux-logger 打印的日志跟我们不使用 immutable.js 有什么区别?

如上图所示,打印的日志数据就是 immutable.js 的相关数据,但是我们会发现阅读性不是太好,这里我们安装一个格式化 immutable.js 的日志数据的 Chrome 插件,安装一下即可,之前我有写过一篇文章教你怎么使用这个插件,点击跳转阅读,安装好之后,我们再来查看数据,如下所示:

是不是增加了日志的可阅读性,到此我们集成 Immutable.js 就至此结束,欢迎大家在下面留言交流!

6、总结

1)上面是教你如何把现有项目集成 immutable.js,如果你是新项目,上面有些配置其实是不用管的;
2)上面的集成原则:把原生的写法改成 immutable.js 的写法即可!;
3)这里我用到了 redux-persist,如果你没有用到这个包,那么你就可以不用安装 redux-persist-transform-immutable,换成 redux-immutable 包即可,具体如何操作,官方文档上面有讲,这里就不多说了。
4)演示地址、本文章代码,另外本文章代码对应 github 上面的 immutable.js 分支,而演示地址对应的是 master 分支!
