从0到1搭建react工程二（antd集成与css预处理配置以及路由配置）

新增依赖

dependencies

• antd
• react-router-dom

devDependencies

• less
• less-loader
• style-loader
• css-loader
• babel-plugin-import

antd组件动态引入配置

新增.babelrc配置

// .babelrc
{
  "plugins": [
    ["import", {
      "libraryName": "antd",
      "style": true // 表示引入less文件
    }]
  ]
}

新增webpack.config.js配置

// webpack.config.js
module: {
  rules: [
    //...
    {
      test: /\.(css|less)/,
      use: ['style-loader', 'css-loader', {
        loader: 'less-loader',
        options: {
          javascriptEnabled: true
        }
      }]
    }
  ]
}

更新index.js

import React from 'react';
import ReactDom from 'react-dom';
import { Button } from 'antd';
import './index.less';

ReactDom.render(
<div className="wrapper"><Button type="primary">按钮</Button></div>,
document.getElementById('app')
);

.wrapper {
  padding: 24px;
  text-align: center;
}

效果如下图所示????

添加路由

// router.js
import React from 'react';
import { HashRouter as Router, Route, Switch } from "react-router-dom";
// 新增Page/Index Page/Example  Page/Error页面
import IndexComponent from './Pages/Index';
import Example from './Pages/Example';
import ErrorPage from './Pages/Error';

const routeConfig = [
  {
    path: '/',
    component: IndexComponent,
  },
  {
    path: '/example',
    component: Example,
  }
]
const routes = (
  <Router>
    <Switch>
      {
        routeConfig.map(item => (
          <Route {...item} exact key={item.path} />
        ))
      }
      <Route component={ErrorPage} />
    </Switch>
  </Router>
)

export default routes;

再次更新index.js

import React from 'react';
import ReactDom from 'react-dom';
import routes from './router';
import './index.less'

ReactDom.render(routes, document.getElementById('app'));

添加新路由页面

// Page/Index
import React from 'react';
import { Button } from 'antd';
import { Link } from 'react-router-dom';

const IndexComp = (props) => {
  return (
  	<div className="wrapper">
  		go to 
  		<Button type="primary"><Link to="/example">Example</Link></Button> 
  		page
  	</div>
  )
}

export default IndexComp;

// Page/Example
import React from 'react';
import { Button } from 'antd';
import { Link } from 'react-router-dom';

const IndexComp = (props) => {
  return (
	<div className="wrapper">
		go to 
		<Button type="primary"><Link to="/example">Example</Link></Button> 
		page
	</div>
  )
}

export default IndexComp;

效果如下图????
