在css加载器中修改localIdentName在webpack 5.17中不起作用

Question

目前我正在使用webpack 5、react 17和@dr.pogodin/babel-plugin-react-css-modules以及所有其他最新软件包。

我排除了资产/样式表中的sass/css文件，这些文件被视为全局文件，并在className中使用这些类

将localIdentName更改为其他内容时不会应用样式。我试过了，但没用。

那么如何更改localIdentName呢？

听起来好像我忘了告诉你Babel-plugin-react-css-模块也有一个配置作用域名称的选项，称为GenerateScopedName。

只要您将其配置为与css加载程序相同，它就应该可以工作：

• .babelrc

[
  "@dr.pogodin/babel-plugin-react-css-modules",
  {
    "generateScopedName": "[name]__[local]___[hash:base64:5]", // switch to whatever you want to
    // ...
  }
]

• webpack.config.js：

{
  loader: "css-loader",
  options: {
    modules: {
      // ...
      localIdentName: "[name]__[local]___[hash:base64:5]",
    },
  },
},

注意：在基于env生成的情况下，您应该使用js babel config filebabel.config.js，这样您就可以通过NODE_env
