Module parse failed: error: semantic/dist/semantic.min.css Unexpected character '@' (11:0)

Question

I use the current version of react-boilerplate (which uses webpack) and installed Semantic-UI-React like described in the official docs http://react.semantic-ui.com/usage

When I start the server I get:

Server started ! ✓

You may need an appropriate loader to handle this file type.

What kind of 'appropriate loader' do I need?

The parser doesn't like the @import statement in /semantic/dist/semantic.min.css:

@import url(https://fonts.googleapis.com/css?family=Lato:400,700,400italic,700italic&subset=latin);

How to resolve this issue?

Answer 1

If you're using an include directive in the rule make sure to include also node_modules:

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

That should fix the problem as it you're instructing webpack to make sure to include node modules when loading css so that it can properly utilize the css-loader when importing the semantic ui css package.

Answer 2

Step1: Install following packages

npm install --save-dev css-loader sass-loader node-sass url-loader file-loader

Step2: Then, in webpack.config.js file:

module: {
    rules: [
        {
            test: /\.css$/,
            loader: 'style-loader!css-loader'
        },
        {
            test: /\.s[a|c]ss$/,
            loader: 'sass-loader!style-loader!css-loader'
        },
        {
            test: /\.(jpg|png|gif|jpeg|woff|woff2|eot|ttf|svg)$/,
            loader: 'url-loader?limit=100000'
        }
    ]
}

Step3: In modules,

If you installed semantic css via npm package npm install --save-dev semantic-ui-css, then import entry should be import './node_modules/semantic-ui-css/semantic.min.css'

Use relavent import statment if you have not installed semantic-ui-css via npm.
