使用create-react-app+react-router-dom+axios+antd+react-redux构建react项目

1、安装、构建

# 全局安装
npm install -g create-react-app
# 构建一个my-app的项目
npx create-react-app my-app
cd my-app

# 启动编译当前的React项目,并自动打开 http://localhost:3000/
npm start

2、项目目录

//默认

├── package.json ├── public # 这个是webpack的配置的静态目录 │ ├── favicon.ico │ ├── index.html # 默认是单页面应用,这个是最终的html的基础模板 │ └── manifest.json ├── src │ ├── App.css # App根组件的css │ ├── App.js # App组件代码 │ ├── App.test.js │ ├── index.css # 启动文件样式 │ ├── index.js # 启动的文件(开始执行的入口)!!!! │ ├── logo.svg │ └── serviceWorker.js └── yarn.lock
//修改

│   └── serviceWorker.js
└── yarn.lock          

 

3、antd

yarn add antd

修改 src/App.css,在文件顶部引入 antd/dist/antd.css

@import '~antd/dist/antd.css';

.App {
  text-align: center;
}

...

antd 目前的默认文案是英文,如果需要使用其他语言,可以参考下面的方案。

antd 提供了一个 React 组件 ConfigProvider 用于全局配置国际化文案。

import zhCN from 'antd/es/locale/zh_CN';

return (
  <ConfigProvider locale={zhCN}>
    <App />
  </ConfigProvider>
);

4、axios

yarn add axios

/src/serve/index.js,统一配置并绑定到react上

import React from 'react';
import axios from 'axios';
axios.defaults.headers['Content-Type'] = 'application/json';


let config = {
  baseURL: '',
  timeout: 60 * 1000, // Timeout
};
const _axios = axios.create(config);
_axios.interceptors.request.use(
  (config) => {
    // Do something before request is sent
    config.headers['Authorization'] = '';
    return config;
  },
  (error) => {
    // Do something with request error
    return Promise.reject(error);
  }
);

// Add a response interceptor
_axios.interceptors.response.use(
  (response) => {
    // Do something with response data
    return response
  },
  (error) => {
    // Do something with response error
    return Promise.reject();
  }
);
React.Component.prototype.$axios = _axios;

5、router

yarn add react-router-dom

/src/router/config.js

import login from '../views/login';
import record from '../views/record';
import home from '../views/home';


export const routerConfig = [
  {
    path:'/',
    component:home,
    auth:true,
  },{
    path:'/record',
    component:record,
    //auth:true,
  },{
    path:'/login',
    component:login,
  }
];

/src/router/FrontendAuth.js

import React, {Component} from 'react';
import {Route, Redirect} from 'react-router-dom';

export class FrontendAuth extends Component {
  render() {
    const {location, config} = this.props;
    const {pathname} = location;
    const isLogin = localStorage.getItem('__config_center_token')

    // 如果该路由不用进行权限校验,登录状态下登陆页除外
    // 因为登陆后,无法跳转到登陆页
    // 这部分代码,是为了在非登陆状态下,访问不需要权限校验的路由
    const targetRouterConfig = config.find((v) => v.path === pathname);
    if (targetRouterConfig && !targetRouterConfig.auth && !isLogin) {
      const {component} = targetRouterConfig;
      return <Route exact path={pathname} component={component}/>
    }

    if (isLogin) {
      // 如果是登陆状态,想要跳转到登陆,重定向到主页
      if (pathname === '/login') {
        return <Redirect to='/'/>
      } else {
        // 如果路由合法,就跳转到相应的路由
        if (targetRouterConfig) {
          return <Route path={pathname} component={targetRouterConfig.component}/>
        } else {
          // 如果路由不合法,重定向到 404 页面
          return <Redirect to='/404'/>
        }
      }
    } else {
      // 非登陆状态下,当路由合法时且需要权限校验时,跳转到登陆页面,要求登陆
      if (targetRouterConfig && targetRouterConfig.auth) {
        return <Redirect to='/login'/>
      } else {
        // 非登陆状态下,路由不合法时,重定向至 404
        return <Redirect to='/404'/>
      }
    }
  }
}

/src/router/index.js

import React, { Component } from 'react';
import { Switch} from 'react-router-dom';

import { FrontendAuth } from './FrontendAuth';
import { routerConfig } from './config';


class Routes extends Component {
  render() {
    return (
      <Switch>
        <FrontendAuth config={routerConfig} />
      </Switch>
    )
  }
}

export default Routes

app.js

import {BrowserRouter as Router} from 'react-router-dom';
import Routes from './router/index'

class App extends Component  {
  render() {
    return (
      <Router>
        <Routes></Routes>
      </Router>
    );
  }
}

export default App;

6、scss

 安装完后,只要把sass文件改成.scss就行了

npm install node-sass sass-loader --save

7、修改端口号

项目默认端口号是3000,如下可以更改:

在package.json中修改
  "start":"react-scripts start",
为
"start":"set PORT=9000 && react-scripts start",

8、react-redux

redux不是项目必需的,如果你不确定是否需要,那就是不需要,在react无法实现时,再考虑。

npm install react-redux redux --S

 /src/redux/action.js

/*
 * action 类型
 */

export const COUNT = 'COUNT';
/*
 * 初始值
 */

export const config = {
    count:1000
};


/*
 * action 创建函数
 */

export function setCount(value) {
    return { type: COUNT, value }
}

/src/redux/reducer.js

//这是action
import {
  COUNT
} from './actions'

//这是reducer
const reducer = (state , action) => {
  switch (action.type) {
    case COUNT:
      let count =  action.value;
      return {...state,...{count}};
    default:
      return state;
  }
};
export default reducer

/src/redux/index.js

import { createStore } from 'redux';
import {config} from './actions';
import reducer from './reducer';
let store = createStore(reducer,config);

export default store

/src/index.js

import { Provider } from 'react-redux'
import store from './redux/index'

ReactDOM.render(
  <ConfigProvider locale={zhCN}>
    <Provider store={store}>
      <App />
    </Provider>
  </ConfigProvider>, document.getElementById('root'));

//页面调用示例

import React, { Component } from 'react';
import { connect } from 'react-redux';
import {
  setCount,
} from '../redux/actions'

class ReduxTest extends Component {

  componentDidMount() {
    console.log(this.props)
  }
  render() {
    const { PayIncrease,tiger } = this.props;
    return (
      <div className="App">
        <h2>当月工资为{tiger}</h2>
        <button onClick={PayIncrease}>升职加薪</button>
      </div>
    );
  }
}
//需要渲染什么数据
function mapStateToProps(state) {
  return {
    tiger: state.count
  }
}
//需要触发什么行为
function mapDispatchToProps(dispatch) {
  return {
    PayIncrease: () => dispatch(setCount(99999)),
  }
}

export default ReduxTest = connect(mapStateToProps, mapDispatchToProps)(ReduxTest)
