        default:
            return state;
    }
}

export default items;

reducers - index.js

import {combineReducers} from 'redux';
import items from './items';
import filter from './filter';

// 生成一个整体的Reducer函数[状态 - Reducer]
export default combineReducers({
    data: items,filter: filter
});

运行：

npm run deves

结果：
