【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
//src\index.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
