在升级的过程中,当配置了css-loadermodules时,启动css modules来为css给定作用域时,发现antd中组件的样式不生效了,配置如下??:

  • webpack配置
  module.exports = {
    ...,
    module: {
      rules: [
        {
          ...
        },
        {
          test: /\.css$/,
          use: [
            ‘style-loader‘,
            {
              loader: ‘css-loader‘,
              options: {
                importLoaders: 1,
                modules: {
                  mode: ‘local‘,
                  localIdentName: ‘[name]__[local]--[hash:base64:5]‘
                }
              }
            },
            ‘postcss-loader‘
          ]
        },
        {
          test: /\.less$/,
          use: [
            ‘style-loader‘,
            {
              loader: ‘css-loader‘,
              options: {
                importLoaders: 2,
                modules: {
                  mode: ‘local‘,
                  localIdentName: ‘[name]__[local]--[hash:base64:5]‘
                }
              }
            },
            ‘postcss-loader‘,
            {
              loader: ‘less-loader‘,
              options: {
                lessOptions: {
                  javascriptEnabled: true
                }
              }
            }
          ]
        },
        {
          ...
        }
      ]
    },
    ...
  }
  • postcss.config.js配置
    module.exports = {
      plugins: [
        require(‘postcss-preset-env‘)({
          browsers: ‘last 2 versions‘
        })
      ]
    }

注意的点:css-loader options中,modules配置随着版本而改变

  • css-loader配置css modules模式
  // 历史版本配置方式
  {
    loader: ‘css-loader‘,
    options: {
      modules: true,
      localIdentName: ‘[name]__[local]--[hash:base64:5]‘,
    }
  }
  
  // 新版配置css modules方式
  {
    loader: ‘css-loader‘,
    options: {
      modules: {
        mode: ‘local‘,
        localIdentName: ‘[name]__[local]--[hash:base64:5]‘
      }
    }
  }

当像上面这样配置时css modules时,项目中样式采用css modules的写法,构建之后会被重命名。如果项目中引入了antd的样式,则会导致样式加载不到问题

解决方式:

  1. 在打包后的html中全局引用antd.css文件,但是就做不到按需加载样式了
  2. 改变webpack配置,css modules模式只应用在业务代码中,而不改变node_modules中三方组件的样式编译方式
  • 修改后的webpack配置
  module.exports = {
    ...,
    module: {
      rules: [
        {
          ...
        },
        {
          test: /\.css$/,
          // 采用css modules的解析方式时,排除对node_modules文件处理
          exclude: [/node_modules/],
          use: [
            MiniCssExtractPlugin.loader,
            {
              loader: ‘css-loader‘,
              options: {
                importLoaders: 1,
                modules: {
                  mode: ‘local‘,
                  localIdentName: ‘[name]__[local]--[hash:base64:5]‘
                }
              }
            },
            ‘postcss-loader‘
          ]
        },
        // 解决使用css modules时antd样式不生效
        {
          test: /\.css$/,
          // 排除业务模块,其他模块都不采用css modules方式解析
          exclude: [/src/],
          use: [‘style-loader‘, ‘css-loader‘]
        },
        {
          test: /\.less$/,
          use: [
            MiniCssExtractPlugin.loader,
            {
              loader: ‘css-loader‘,
              options: {
                importLoaders: 2,
                modules: {
                  localIdentName: ‘[name]__[local]--[hash:base64:5]‘
                }
              }
            },
            ‘postcss-loader‘,
            {
              loader: ‘less-loader‘,
              options: { lessOptions: { javascriptEnabled: true } }
            }
          ]
        },
        {
          ...
        }
      ]
    },
    ...
  }
