react typescript 使用antd 按需引入和使用自定义主题

最近在前端开发和使用过程中，发现了antd只要与其样式的类名相同就会出现覆盖问题。查看官方文档以及踩了很多坑之后，确定此放发可行

1. 在自己的工程中安装相关依赖

yarn add antd

按需加载

yarn add babel-plugin-import

自定义主题

yarn add craco-antd

yarn add @craco/craco

按需加载与自定义主题之间需要less-loader， 本项目使用craco-less

yarn add craco-less

 

注意：在安装过程中，我使用cnpm或者npm总是出现各种各样的问题，不是很稳定。通过使用yarn之后，排除了相关问题，其中yarn相对稳定

2.  在项目的根目录创建文件

craco.config.js 文件名一定不能错误，否则找不到文件

const CracoLessPlugin = require('craco-less');

module.exports = {
    plugins: [
        {
            plugin: CracoLessPlugin,
            options: {
                lessLoaderOptions: {
                    lessOptions: {
                        modifyVars: { '@primary-color': 'orange' },
                        javascriptEnabled: true,
                    },
                },
            },
        },
    ],
    /*babel 这里是新增的 按需加载 */
    babel: {
        plugins: [
            ['import', { libraryName: 'antd', libraryDirectory: 'es', style: true  }],
            ['@babel/plugin-proposal-decorators', { legacy: true }]
        ]
    }
    /*新增结束*/
};

3. 修改package.json文件
需要修改的地方我增加了背景色

"start": "craco start",
"build": "craco build",
"test": "craco test",

完成的文件是

{
  "name": "lab",
  "version": "0.1.0",
  "private": true,
