项目搭建react + react-router + react-redux + typescript + axios + webpack + less

npx create-react-app my-app --template typescript
cd my-app
npm start

           

yarn add antd

           

yarn add react-app-rewired customize-cra
           

/* package.json */
"scripts": {
-   "start": "react-scripts start",
+   "start": "react-app-rewired start",
-   "build": "react-scripts build",
+   "build": "react-app-rewired build",
-   "test": "react-scripts test",
+   "test": "react-app-rewired test",
}
           

然后在项目根目录创建一个

config-overrides.js

用于修改默认配置。

module.exports = function override(config, env) {
  // do stuff with the webpack config...
  return config;
};
           

babel-plugin-import 是一个用于按需加载组件代码和样式的 babel 插件（原理），现在我们尝试安装它并修改

config-overrides.js

文件。

$ yarn add babel-plugin-import
           

+ const { override, fixBabelImports } = require('customize-cra');

- module.exports = function override(config, env) {
-   // do stuff with the webpack config...
-   return config;
- };
+ module.exports = override(
+   fixBabelImports('import', {
+     libraryName: 'antd',
+     libraryDirectory: 'es',
+     style: 'css',
+   }),
+ );
           

// src/App.tsx
  import React, { Component } from 'react';
+ import { Button } from 'antd';
  import './App.css';

  class App extends Component {
    render() {
      return (
        <div className="App">
          <Button type="primary">Button</Button>
        </div>
      );
    }
  }

  export default App;
           

yarn add less less-loader
           

- const { override, fixBabelImports } = require('customize-cra');
+ const { override, fixBabelImports, addLessLoader } = require('customize-cra');

module.exports = override(
  fixBabelImports('import', {
    libraryName: 'antd',
    libraryDirectory: 'es',
-   style: 'css',
+   style: true,
  }),
+ addLessLoader({
+   javascriptEnabled: true,
+   modifyVars: { '@primary-color': '#1DA57A' },
+ }),
);
           

使用 Day.js 替换 momentjs 优化打包大小#

yarn add antd-dayjs-webpack-plugin
           

npm install --save react-router-dom
# or
yarn add react-router-dom
           

$ npm install http-proxy-middleware --save
$ # or
$ yarn add http-proxy-middleware
           

Next, create

src/setupProxy.js

and place the following contents in it:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
  // ...
};
           

You can now register proxies as you wish! Here’s an example using the above

http-proxy-middleware

:

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function(app) {
  app.use(
    '/api',
    createProxyMiddleware({
      target: 'http://localhost:5000',
      changeOrigin: true,
    })
  );
};
           

npm install axios
# or
yarn add axios
           

npm install react-app-polyfill
# or
yarn add react-app-polyfill

If you are supporting Internet Explorer 9 or Internet Explorer 11 you should include both the

ie9

or

ie11

and

stable

modules:

For IE9:

// These must be the first lines in src/index.js
import 'react-app-polyfill/ie9';
import 'react-app-polyfill/stable';

// ...
           

For IE11:

// These must be the first lines in src/index.js
import 'react-app-polyfill/ie11';
import 'react-app-polyfill/stable';

// ...
