I'm trying to import the CSS for the react-image-gallery package and I'm getting the error below:

What am I doing wrong?

Do I need a CSS pre-processor loader?

From react-image-gallery docs:

SCSS

@import "node_modules/react-image-gallery/styles/scss/image-gallery.scss";

CSS

@import "node_modules/react-image-gallery/styles/css/image-gallery.css";

Webpack

import "react-image-gallery/styles/css/image-gallery.css";

As per the documentation above, I'm currently trying:

import "react-image-gallery/styles/css/image-gallery.css";

My webpack.config:

module: {
    rules:[
      {
        test: /\.css$/,
        include: path.resolve(__dirname, 'src'),
        use: ['style-loader','css-loader'],
      },

The error I'm getting:

ERROR in ./node_modules/react-image-gallery/styles/css/image-gallery.css 1:0
Module parse failed: Unexpected character '@' (1:0)
You may need an appropriate loader to handle this file type.

  • It seems to be an error with the include property on my webpack.config file... How is the proper way to configure the css loader? Commented May 6, 2019 at 14:55

Reset to default

After 2 hours struggling I found a solution to my problem.

My problem was that I wanted to import immediately the package and style as it is in the documentation.

Like this

npm install react-image-gallery
@import "~react-image-gallery/styles/scss/image-gallery.scss";

However, I did not configure it from the webpack, as a result, I got the following error.

ERROR in ./node_modules/react-image-gallery/styles/scss/image-gallery.scss 1:16
Module parse failed: Unexpected token (1:16)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> $ig-small-screen: 768px !default;
| $ig-xsmall-screen: 480px !default;
| $ig-white: #fff !default;
 @ ./src/views/accommodation/ViewSpecificAccommodation.js 8:0-60
 @ ./src/App.js
 @ ./src/index.js

Thanks, @cbdeveloper for the support.

My solution is that I added the react-image-gallery style in webpack.config.babel.js configuration. I 've included the path from node_modules, not src/assets.

This is the rule I added with style path.

   {
     include: path.resolve(__dirname, './node_modules/react-image-gallery/styles/scss/image-gallery.scss'),
     test: /\.(s[ac]ss|css)$/i,
     use: [
       'style-loader',
       'css-loader',
       'sass-loader',
     ],
   },

webpack.config.babel.js

import path from 'path';
import Dotenv from 'dotenv-webpack';
import HtmlWebpackPlugin from 'html-webpack-plugin';
const webpack = {
  mode: 'development',
  entry: path.resolve(__dirname, 'src/index'),
  output: {
    path: path.resolve(__dirname, 'dist/'),
    filename: 'bundle.js',
    publicPath: '/',
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        include: path.resolve(__dirname, 'src'),
        use: ['babel-loader'],
      },
      {
        test: /\.(png|jpe?g|gif)$/i,
        include: path.resolve(__dirname, 'src'),
        use: [
          {
            loader: 'file-loader',
          },
        ],
      },
      {
        include: path.resolve(__dirname, './src/assets'),
        test: /\.(s[ac]ss|css)$/i,
        use: [
          'style-loader',
          'css-loader',
          'sass-loader',
        ],
      },
      {  // I 've added a new rule and I included the style path from node_modules
        include: path.resolve(__dirname, './node_modules/react-image-gallery/styles/scss/image-gallery.scss'),
        test: /\.(s[ac]ss|css)$/i,
        use: [
          'style-loader',
          'css-loader',
          'sass-loader',
        ],
      },
    ],
  },
  resolve: {
    extensions: ['*', '.js', '.jsx'],
  },
  devServer: {
    contentBase: path.resolve(__dirname, 'public/'),
    historyApiFallback: true,
    port: 4000,
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: 'public/index.html',
    }),
    new Dotenv({
      path: './.env',
      safe: true,
      systemvars: true,
      silent: true,
      defaults: false,
    }),
  ],
  node: {
    fs: 'empty',
  },
};
export default webpack;

Reminder: Just remember to install the following packages - style-loader, - css-loader, - sass-loader,

The error was on this line: My webpack.config:

module: {
    rules:[
      {
        test: /\.css$/,
        // include: path.resolve(__dirname, 'src'), (IT WORKS WHEN YOU REMOVE THIS LINE)
        use: ['style-loader','css-loader'],
      },

The problem was that I was only including into the css-loader and style-loader the src folder. But the CSS I was trying the import was on the node_modules folder. So I need to include that as well. Hence, by not using the include condition, I'm including CSS from any folder.

In Vite just remove ~:

@import "react-image-gallery/styles/css/image-gallery.css";
