Craco Ant Design Plugin

This is a craco plugin that makes it easy to use the Ant Design UI library with create-react-app version >= 2.

Use react-app-rewired for create-react-app version 1.

craco-antd includes:

Less (provided by craco-less)
babel-plugin-import to only import the required CSS, instead of everything
An easy way to customize the theme. Set your custom variables in ./antd.customize.less

Supported Versions

The latest version of craco-antd is tested with:

react-scripts: ^5.0.0
@craco/craco: ^6.4.3
craco-less: ^2.0.0

Installation

First, follow the beginning of the Ant Design create-react-app Documentation to set up your app with Ant Design. (Stop before the "Advanced Guides" section, because this plugin handles all of that for you.)

Then, follow the craco Installation Instructions to install the craco package, create a craco.config.js file, and modify the scripts in your package.json.

Then install craco-antd and antd:

$ yarn add craco-antd antd

# OR

$ npm i -S craco-antd antd

craco-antd only has a "peer dependency" for antd >= 3.0.0. You should add antd to your own package.json and use a fixed version (e.g. 3.11.2). Be careful when upgrading antd, because unexpected changes could break your application.

Basic Usage

Here is a complete craco.config.js configuration file that sets up Less compilation and babel-plugin-import for create-react-app:

const CracoAntDesignPlugin = require("craco-antd");

module.exports = {
  plugins: [{ plugin: CracoAntDesignPlugin }],
};

Advanced Usage

Here is a production-ready craco.config.js file that sets up webpackbar and webpack-bundle-analyzer. It also sets up Preact with the craco-preact plugin. (Preact is faster and smaller than React, and it works fine with Ant Design.)

I put my custom theme variables in src/style/AntDesign/customTheme.less. I also use that folder for some custom components and other CSS.

const { BundleAnalyzerPlugin } = require("webpack-bundle-analyzer");
const WebpackBar = require("webpackbar");
const CracoAntDesignPlugin = require("craco-antd");
const path = require("path");

// Don't open the browser during development
process.env.BROWSER = "none";

module.exports = {
  webpack: {
    plugins: [
      new WebpackBar({ profile: true }),
      ...(process.env.NODE_ENV === "development"
        ? [new BundleAnalyzerPlugin({ openAnalyzer: false })]
        : []),
    ],
  },
  plugins: [
    { plugin: require("craco-preact") },
    {
      plugin: CracoAntDesignPlugin,
      options: {
        customizeThemeLessPath: path.join(
          __dirname,
          "src/style/AntDesign/customTheme.less"
        ),
      },
    },
  ],
};

See the Reload Custom Variables During Development section to wrap your "start" script with nodemon.

Customize Ant Design Theme

You can modify the default Ant Design theme by changing some Less variables.

craco-antd will look for variables in a Less file at ./antd.customize.less. (You can customize this file path with the customizeThemeLessPath option.)

// ./antd.customize.less
@primary-color: #1da57a;
@link-color: #1da57a;

Here's a list of all the variables that can be modified.

You can also customize these variables directly in your craco.config.js with the customizeTheme option:

const CracoAntDesignPlugin = require("craco-antd");

module.exports = {
  plugins: [
    {
      plugin: CracoAntDesignPlugin,
      options: {
        customizeTheme: {
          "@primary-color": "#1DA57A",
          "@link-color": "#1DA57A",
        },
      },
    },
  ],
};

customizeTheme is just an alias for the modifyVars option in less-loader.

If you use multiple options to customize the theme variables, they are merged together in the following order:

The file at options.customizeThemeLessPath (default: ./antd.customize.less)
options.customizeTheme
options.lessLoaderOptions.modifyVars

For more information, see Ant Design's "Customize Theme" documentation.

Reload Custom Variables During Development

The webpack dev server needs to be restarted whenever you make a change to your custom theme variables. (It's not possible to reload this file automatically, because the variables are set in the webpack config. I tried to fix this issue but hit a dead-end.)

However, you can automatically restart webpack by wrapping craco start with nodemon.

Install nodemon:

yarn add -D nodemon

# Or globally (not recommended):

npm install -g nodemon

Update the "start" script in package.json:

"scripts": {
  "start": "nodemon -w ./antd.customize.less --exec \"craco start\"",
}

(Change ./antd.customize.less if you are using a different file.)

The webpack dev server will now be restarted whenever you make a change to ./antd.customize.less.

Restart Webpack When `craco.config.js` Changes

While you're here, you can also add -w craco.config.js to restart webpack whenever your craco configuration changes (craco doesn't do this automatically):

"scripts": {
  "start": "nodemon -w craco.config.js -w ./antd.customize.less --exec \"craco start\"",
}

Disable "Open In Browser"

By default, create-react-app will open a new browser tab every time it starts. This can be really annoying, especially if you set up the nodemon watcher. You can disable this behavior with an environment variable: BROWSER=none.

You can set this in an .env file:

BROWSER=none

I prefer to set it at the top of craco.config.js:

// Don't open the browser during development
process.env.BROWSER = "none";

Options

You can pass an options object to configure the loaders and plugins. You can also pass a modifyLessRule callback to have full control over the Less webpack rule. See the craco-less documentation for more information about these options:

options.styleLoaderOptions
options.cssLoaderOptions
options.postcssLoaderOptions
options.lessLoaderOptions
options.miniCssExtractPluginOptions
options.modifyLessRule

See the babel-plugin-import documentation for more information about this option:

options.babelPluginImportOptions

Example:

module.exports = {
  plugins: [
    {
      plugin: CracoAntDesignPlugin,
      options: {
        lessLoaderOptions: {
          modifyVars: { "@primary-color": "#1DA57A" },
          strictMath: true,
          noIeCompat: true,
        },
        cssLoaderOptions: {
          modules: true,
          localIdentName: "[local]_[hash:base64:5]",
        },
        babelPluginImportOptions: {
          libraryDirectory: "es",
        },
      },
    },
  ],
};

Large Bundle Size from Ant Design Icons

You can use the webpack-bundle-analyzer plugin to see a breakdown of all the JS and CSS in your webpack build. Here's how to add this plugin to your craco.config.js configuration file:

const { BundleAnalyzerPlugin } = require("webpack-bundle-analyzer");

module.exports = {
  webpack: {
    plugins: [new BundleAnalyzerPlugin()],
  },
  plugins: [{ plugin: require("craco-antd") }],
};

If you have imported any icons from Ant Design, you will see a very large (> 500KB) entry for @ant-design/icons/lib:

This is a problem with Ant Design v3.9.0+, and it will be fixed in the next version. See this GitHub issue for more information. This comment talks about the fix, and here is the PR.

In the meantime, you can set up an import alias and only include the required icons.

Further Configuration

If you need to configure anything else for the webpack build, take a look at the Configuration Overview section in the craco README. You can use CracoAntDesignPlugin while making other changes to babel and webpack, etc.
