• 【react】react-bookManager


    作者可能是本意想要做一个图书管理系统,不过添加书籍的时候报错,所以简单的页面我们简单的看看
    先上github地址:https://github.com/hesisi/react-bookManager
    看package.json文件是有用到中间件的,心里多了点期待,也许帮它修复好bug也行呢
    先看页面

    很简单,可能只是框架的效果吧
    看看代码

    //srcindex.js
    import React from 'react';
    import ReactDOM from 'react-dom';
    import './index.css';
    import App from './App';
    import registerServiceWorker from './registerServiceWorker';
    // 引入中间件
    import {Provider} from 'react-redux';
    // reducer
    import bookReducer from './reducers/bookReducer';
    // userreducer
    import userReducer from './reducers/userReducer';
    import { createStore ,applyMiddleware ,combineReducers } from 'redux';
    import thunk from 'redux-thunk';
    
    const rootReducer = combineReducers({
        bookReducer,
        userReducer
    });
    //store
    const store = createStore(rootReducer,applyMiddleware(thunk));
    
    ReactDOM.render(
        <Provider store={store}>
            <App />
        </Provider>,
        document.getElementById('root')
    );
    
    store.subscribe(() => {
        console.log("================监听store变化:"+JSON.stringify(store));
    });
    
    registerServiceWorker();
    
    //app.js中定义了几个去不同页面的路由
    import React from 'react'; 
    import ReactDOM from 'react-dom'; 
    import HomeLayout from './layouts/HomeLayout';
    
    import BookAdd from './components/BookAdd';
    import BookListContainer from './containers/BookList';
    import UserAdd from './components/UserAdd';
    import UserListContainer from './components/UserList';
    import FileAdd from './components/FileAdd';
    import FileList from './components/FileList';
    import { BrowserRouter as Router ,Route } from 'react-router-dom';
    import registerServiceWorker from './registerServiceWorker'; 
    
    {/*
        store的数据结构
    
        store = {
            bookReducer : {
                data : [{},{}]
            },
    
            userReducer : {
                data : [{},{}]
            }
        }
    
    */}
    
    class App extends React.Component{
        render (){
            return (
                <Router>
                    <HomeLayout>  
                        <div>
                            <Route path="/book/add" component={BookAdd}></Route>
                            <Route path="/book/list" component={BookListContainer}></Route>
                            <Route path="/user/add" component={UserAdd} ></Route>
                            <Route path="/user/list" component={UserListContainer}></Route>
                            <Route path="/file/add" component={FileAdd}></Route>
                            <Route path="/file/list" component={FileList}></Route>
                        </div>
                    </HomeLayout>
                </Router>
            );
        
        }
    }
    
    
    export default App;
    

    接下来我们根据路由看一下页面

    //user/list
    //应该是数据部分请求没有接口,所以没有数据渲染出来
