react中自定义antd主题与支持less，第二部

自定义主题

首先自定义主题需要修改antd，antd本身也是less写的之后编译成css的，所以当我们需要使用less。

1.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);
+   config = rewireLess.withLoaderOptions({
+     modifyVars: { "@primary-color": "#1DA57A" },
+   })(config, env);
    return config;
  };

使用less

如果已经配置react-app-rewire-less，则无需再进行此操作

1.npm install less-loader less --save-dev

2.修改node_modules/react_script/config下的webpack.config.dev.js 和 webpack.config-prod.js 配置文件

• test: /\.css$/ 改为 /\.(css|less)$/
• test: /\.css$/ 的 use 数组配置增加 less-loader

{
  test: /\.(css|less)$/,
  use: [
    require.resolve('style-loader'),
    {
      loader: require.resolve('css-loader'),
      options: {
        importLoaders: 1,
      },
    },
    {
      loader: require.resolve('postcss-loader'),
      options: {
        // Necessary for external CSS imports to work
        // https://github.com/facebookincubator/create-react-app/issues/2677
        ident: 'postcss',
        plugins: () => [
          require('postcss-flexbugs-fixes'),
          autoprefixer({
            browsers: [
              '>1%',
              'last 4 versions',
              'Firefox ESR',
              'not ie < 9', // React doesn't support IE8 anyway
            ],
            flexbox: 'no-2009',
          }),
        ],
      },
    },
    {
      loader: require.resolve('less-loader') // compiles Less to CSS
    }
  ],
},
