how can I resolve this css class issue in JS project?

I am trying to build a single page html app using Javascript. I have the css file in the same folder 'src' along with the index.js file. My webpack.config.js file is as follows:






var path = require('path');

var webpack = require('webpack');

var vtkRules = require('vtk.js/Utilities/config/dependency.js').webpack.core.rules;



// Optional if you want to load *.css and *.module.css files

// var cssRules = require('vtk.js/Utilities/config/dependency.js').webpack.css.rules; 



var entry = path.join(__dirname, './src/index.js');

const sourcePath = path.join(__dirname, './src');

const outputPath = path.join(__dirname, './dist');



module.exports = {

  entry,

  output: {

    path: outputPath,

    filename: 'MyWebApp.js',

  },

module: {

     rules: [{

         test:  [/.js$/, /.jsx$/, /.es6$/],

         include: [

           path.resolve(__dirname, 'src'),

         ],

         use: {

           loader: "babel-loader"

         },

       }, {

         test: [/.css/],

         exclude: path.resolve(__dirname, 'src'),

         use: [

           'style-loader',

           {

             loader: 'css-loader',

             options: {

                 modules: true,

                 localIdentName: '[name]__[local]-[hash:base64:5]'

             }

           }

         ]

      }, {

        test: [/.css/],

        include: path.resolve(__dirname, 'src'),

        use: [

          'style-loader',

          'css-loader'

        ]

      }]

   },



  resolve: {

    modules: [

      path.resolve(__dirname, 'node_modules'),

      sourcePath,

    ],

  },

};





Here is my GeometryViewer.module.css file:

  background-size: contain;

  border-radius: 10px;

  width: 50px;

  padding: calc(50vh - 2em) calc(50vw - 25px - 2em);

  cursor: pointer;

}



.selector {

  margin: 5px;

  z-index: 1;

label.selector {

  text-overflow: ellipsis;

  overflow: hidden;

}



select:focus {

  outline: none;

}



.progress {

  z-index: 1;

  left: 10px;

  background-color: rgba(255, 255, 255, 0.5);

  border-radius: 5px;

  border: solid 1px gray;

}





When I try to build the project using 




npm run build





I am getting this error:






ERROR in ./src/GeometryViewer.module.css (./node_modules/css-loader!./src/GeometryViewer.module.css)

Module build failed (from ./node_modules/css-loader/index.js):

Error: composition is only allowed when selector is single :local class name not in ".dark", ".dark" is weird





I would appreciate some help in identifying what I could be doing wrong.

The error is telling you exactly where the issue is. You are not allowed to compose when the selector is a single :local class name. If that component is yours, then you will need to update the styles.



If the component is not yours and part of a node_module (which it appears it is), you may need to change the way you are doing your import in your project. There is a lot of discussion here about how to resolve that.

const outputPath = path.join(__dirname, './dist');



module.exports = {

  },

module: {

  • Sorry I did not see your question on my above answer until now. You should be aware that this loader you have configured will treat ALL .css files as if they are CSS Modules. If you have any plain CSS from any dependency (since I see you are including the node_modules folder) you may run into problems. I'd recommend that you configure a separate rule for .module.css that has modules enabled and exclude .module.css from the other loader with modules disabled.

I was able to solve my own problem. Here is the revised webpack file that worked:






var path = require('path');

var webpack = require('webpack');

var vtkRules = require('vtk.js/Utilities/config/dependency.js').webpack.core.rules;



// Optional if you want to load *.css and *.module.css files

// var cssRules = require('vtk.js/Utilities/config/dependency.js').webpack.css.rules; 



var entry = path.join(__dirname, './src/index.js');

const sourcePath = path.join(__dirname, './src');

const outputPath = path.join(__dirname, './dist');



module.exports = {

  entry,

  output: {

    path: outputPath,

    filename: 'MyWebApp.js',

  },

module: {

     rules: [

     

     { test: /.html$/, loader: 'html-loader' },

  • Sorry I did not see your question on my above answer until now. You should be aware that this loader you have configured will treat ALL .css files as if they are CSS Modules. If you have any plain CSS from any dependency (since I see you are including the node_modules folder) you may run into problems. I'd recommend that you configure a separate rule for .module.css that has modules enabled and exclude .module.css from the other loader with modules disabled.
