I am having difficulty in getting CSS loading using css-loader on my JSX files. I was following the example from:
https://christianalfoni.github.io/react-webpack-cookbook/Loading-CSS.html
This is my JSX
import React from 'react';
import ReactDOM from 'react-dom';
import styles from './styles.css';
class Hello extends React.Component {
render() {
return <div>Hello world!</div>
}
}
var el = document.getElementById('content')
var data = JSON.parse(el.getAttribute('data-attr'))
ReactDOM.render(<Hello data={data} />, el);`
This is my package.json
"devDependencies": {
"babel-core": "^6.3.26",
"babel-loader": "^6.2.0",
"babel-preset-es2015": "^6.3.13",
"babel-preset-react": "^6.3.13",
"css-loader": "^0.23.1",
"exports-loader": "~0.6.2",
"expose-loader": "~0.6.0",
"grunt": "^0.4.5",
"grunt-babel": "^6.0.0",
"grunt-cli": "^0.1.13",
"grunt-contrib-watch": "^0.6.1",
"grunt-webpack": "^1.0.11",
"history": "^1.17.0",
"imports-loader": "~0.6.3",
"jquery": "^2.1.4",
"lodash": "~3.0.0",
"react": "^0.14.5",
"react-dom": "^0.14.5",

"webpack-dev-server": "^1.14.0"
},
"dependencies": {
"chunk-manifest-webpack-plugin": "0.0.1",
"grunt-react": "^0.12.3"
}
This is my Webpack.config.js
var path = require('path');
var webpack = require('webpack');
var config = module.exports = {
// the base path which will be used to resolve entry points
context: __dirname,
// the main entry point for our application's frontend JS
entry: './app/frontend/javascripts/entry.js',
stats: {
// Configure the console output
colors: true,
modules: true,
reasons: true
},
progress: true,
keepalive: true,
module: {
loaders: [
{
test: /\.js?$/,
exclude: /(node_modules|bower_components)/,
loader: 'babel-loader', // 'babel-loader' is also a legal name to reference
query: { presets: ['es2015', 'react'] }
},
{ test: /\.css$/, loader: "style-loader!css-loader" }
]
},
output: {
// this is our app/assets/javascripts directory, which is part of the Sprockets pipeline
path: path.join(__dirname, 'app', 'assets', 'javascripts'),
// the filename of the compiled bundle, e.g. app/assets/javascripts/bundle.js
filename: 'bundle.js',
// if the webpack code-splitting feature is enabled, this is the path it'll use to download bundles
publicPath: '/assets',
devtoolModuleFilenameTemplate: '[resourcePath]',
devtoolFallbackModuleFilenameTemplate: '[resourcePath]?[hash]',
},
resolve: {
// tell webpack which extensions to auto search when it resolves modules. With this,
// you'll be able to do `require('./utils')` instead of `require('./utils.js')`
extensions: ['', '.js'],
// by default, webpack will search in `web_modules` and `node_modules`. Because we're using
// Bower, we want it to look in there too
modulesDirectories: [ 'node_modules', 'bower_components' ],
},
plugins: [
// we need this plugin to teach webpack how to find module entry points for bower files,
// as these may not have a package.json file
new webpack.ResolverPlugin([
new webpack.ResolverPlugin.DirectoryDescriptionFilePlugin('.bower.json', ['main'])
]),
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
}),
//new webpack.optimize.CommonsChunkPlugin('common-bundle.js'),
//new webpack.optimize.CommonsChunkPlugin('public-bundle.js')
]
};
This is my styles.css
#div {
background-color: red;
}
The output I get from running my grunt task to run 'webpack' attached: You can see where it says the build failed for the CSS.

When you say
import styles from './styles.css';
you're trying to import a module that's not being exported as a module.
Try
import './styles.css';
instead to make it a simple file import.
I encounter this problem too. But in my case, I found my loader was written as
{test: '/\.css$/', loader: 'style!css'}
which should be correctly written as
{test: /\.css$/, loader: 'style!css'}
note the '' around the /.css$/
I wise this would be helpful for you.
