4	Use in create-react-app

create-react-app is one of the best React application development tools. We are going to use antd within it and modify the webpack config for some customized needs.

---

Install and Initialization

We need to install create-react-app first, you may need install yarn too.

$ npm install -g create-react-app yarn

Create a new project named antd-demo.

$ create-react-app antd-demo

The tool will create and initialize environment and dependencies automaticly, please try config your proxy setting or use other npm registry if any network errors happen during it.

Then we go inside antd-demo and start it.

$ cd antd-demo
$ yarn start

Open the browser at http://localhost:3000/. It renders a header saying "Welcome to React" on the page.

Import antd

Below is the default directory structure.

├── README.md
├── package.json
├── public
│   ├── favicon.ico
│   └── index.html
├── src
│   ├── App.css
│   ├── App.js
│   ├── App.test.js
│   ├── index.css
│   ├── index.js
│   └── logo.svg
└── yarn.lock

Now we install antd from yarn or npm.

$ yarn add antd

Modify src/App.js, import Button component from antd.

import React, { Component } from 'react';
import Button from 'antd/lib/button';
import './App.css';

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

export default App;

Add antd/dist/antd.css at the top of src/App.css.

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

.App {
  text-align: center;
}

...

Ok, you now see a blue primary button displaying on the page. Next you can choose any components of antd to develop your application. Visit other workflow of create-react-app at its User Guide .

Advanced Guides

We are successfully running antd components now but in the real world, there are still lots of problems about antd-demo. For instance, we actually import all styles of components in the project which maybe a network perfermance issue.

Now we need to customize the default webpack config. We can achieve that by using react-app-rewired which is one of custom create-react-app config solutions.

Import react-app-rewired and modify the scripts field in package.json.

$ yarn add react-app-rewired --dev

/* 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 --env=jsdom",
+   "test": "react-app-rewired test --env=jsdom",
}

Then create a config-overrides.js at root directory of your project for futher overriding.

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

Use babel-plugin-import

babel-plugin-import is a babel plugin for importing components on demand (How does it work?). We are now trying to install it and modify config-overrides.js.

$ yarn add babel-plugin-import --dev

+ const { injectBabelPlugin } = require('react-app-rewired');

  module.exports = function override(config, env) {
+   config = injectBabelPlugin(['import', { libraryName: 'antd', style: 'css' }], config);
    return config;
  };

Remove the @import '~antd/dist/antd.css'; statement added before because babel-plugin-import will import styles and import components like below:

  // scr/App.js
  import React, { Component } from 'react';
- import Button from 'antd/lib/button';
+ 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;

Then reboot with yarn start and visit demo page, you should not find any warning message in the console which prove that the import on demand config is working now. You will find more info about it in this guide.

Customize Theme

According to Customize Theme documentation, we need less variables modify ability of less-loader. We could use react-app-rewire-less to achieve that, import it and modify config-overrides.js like below.

$ yarn add react-app-rewire-less --dev

  const { injectBabelPlugin } = require('react-app-rewired');
+ const rewireLess = require('react-app-rewire-less');

  module.exports = function override(config, env) {
-   config = injectBabelPlugin(['import', { libraryName: 'antd', style: 'css' }], config);
+   config = injectBabelPlugin(['import', { libraryName: 'antd', style: true }], config);  // change importing css to less
+   config = rewireLess(config, env, {
+     modifyVars: { "@primary-color": "#1DA57A" },
+   });
    return config;
  };

We use modifyVars option of less-loader here, you can see a green button rendered on the page after reboot start server.

eject

You can also could try yarn run eject for custom setup of create-react-app, although you should dig into it by yourself.

Source code and other boilerplates

Finally, we used antd with create-react-app successfully, you can learn these practice for your own webpack workflow too, and find more webpack configs in the atool-build. (For instance, add moment noParse to avoid loading all language files)

There are a lot of great boilerplates like create-react-app in React community. There are some source code samples of importing antd in them if you encounter some problems.

• create-react-app-antd
• comerc/cra-ts-antd
• react-boilerplate/react-boilerplate
• kriasoft/react-starter-kit
