webpack does not output css

Situation
I have a webpack setup, where I have a rule that extracts CSS and/or SASS from .ts files using the extract-text-webpack-plugin and sass-loader.
I import my SCSS file in a seperate .ts file
import './scss/style.scss'
Problem
A CSS file is expected to be in the output folder ( dist ).
The compilation completes without an error, yet there is no CSS file in the build folder.
Here is my webpack configuration:
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var styleString = require('css-to-string-loader');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
const extractSass = new ExtractTextPlugin({
filename: "[name].css",
disable: process.env.NODE_ENV === "development"
});
var helpers = require('./helpers');
var isProd = process.env.NODE_ENV === 'production';
module.exports = {
entry: {
polyfills: './src/polyfills.ts',
vendor: './src/vendor.ts',
app: isProd ? './src/main.aot.ts' : './src/main.ts'
},
resolve: {
extensions: ['.ts', '.js']
},
module: {
rules: [{
test: /\.ts$/,
loaders: [
'babel-loader',
{
loader: 'awesome-typescript-loader',
options: {
configFileName: isProd ?
helpers.root('tsconfig-aot.json') :
helpers.root('tsconfig.json')
}
},
'angular2-template-loader'
],
exclude: [/node_modules/]
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015']
}
},
{
test: /\.html$/,
loader: 'html-loader'
},
{
test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
loader: 'file-loader?name=assets/[name].[ext]'
},
{
test: /\.(json)$/,
loader: 'file-loader?name=assets/mocks/[name].[ext]'
},
{
test: /\.(css|scss)$/,
loaders: ['to-string-loader', 'css-loader', 'sass-loader']
}
]
},
plugins: [
// Workaround for angular/angular#11580
new webpack.ContextReplacementPlugin(
// The (\\|\/) piece accounts for path separators in *nix and Windows
/angular(\\|\/)core(\\|\/)#angular/,
helpers.root('./src'), // location of your src
{} // a map of your routes
),
new webpack.optimize.CommonsChunkPlugin({
name: ['app', 'vendor', 'polyfills']
}),
new HtmlWebpackPlugin({
template: 'src/index.html'
})
]
};

Reason
The reason there is not output CSS file is because you are not using the
const extractSass = new ExtractTextPlugin({
filename: "[name].css",
disable: process.env.NODE_ENV === "development"
});
in your CSS|SCSS rule
{
test: /\.(css|scss)$/,
loaders: ['to-string-loader', 'css-loader', 'sass-loader']
}
Solution
You have to make use of the use property like so:
{
test: /\.(css|scss)$/,
use: extractSass.extract({ // <==== Right here, note the "extractSass"
use: [
{ loader: "to-string-loader" },
{ loader: "css-loader" },
{ loader: "sass-loader" }
],
fallback: "style-loader"
})
}
And add to your plugins array the ExtractTextPlugin instance ( extractSass ):
plugins: [
extractSass
]

Can't load templates with routeprovider when using webpack

I recentley migrated from grunt to webpack and I can't figure how to require/import my templates. I have looked at several similar issues with no luck.
Here is my webpack.config file:
var webpack = require('webpack');
var globby = require('globby');
var path = require('path');

var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {

styles: globby.sync(['./content/styles/*.css']),
images: globby.sync(['./content/images/*.*']),

}),
],
externals: [

}
The public folder builds as it should with .js, styles, images etc. But simple navigation results in this error:
ERROR in ./app/app.config.js
Module not found: Error: Can't resolve 'app/varegruppe/templates/index.html' in 'C:\Users\oystein\work\EPD.SPA\EpdSPA\app'
# ./app/app.config.js 50:25-71
Here is an example of how the routes are defined:
$routeProvider.when('/produkteier', {
templateUrl: require('app/produkteier/templates/view.html')
})

Using this plugin I managed to copy all the html files in to the public directory, with the following config:
var CopyWebpackPlugin = require('copy-webpack-plugin');
new CopyWebpackPlugin([
{from: './app/**/*.html', to: './'}
])

Compile scss with webpack for an Angular App

I'm using webpack 3 for my angular app. I have some issues with compiling my scss files. Here is full webpack config file:
const path = require('path')
const autoprefixer = require('autoprefixer')
const CommonsChunkPlugin = require('webpack/lib/optimize/CommonsChunkPlugin')
const UglifyJSPlugin = require('uglifyjs-webpack-plugin')

]
},
output: {

After running webpack i've got this error:
ERROR in ./assets/sass/main.scss
Module parse failed: /home/git/project/src/public/src/assets/sass/main.scss Unexpected token (1:13)
You may need an appropriate loader to handle this file type.
| $header-color: #ffffff;
| $admin-panel-height: 40px;
|
# ./index.js 3:0-34
Also i tried to use this loader: https://github.com/webpack-contrib/sass-loader
After webpack build there no errors appeared, but css file also was not created in /app folder.
file main.scss imports in index.js:
import './assets/sass/main.scss'
Can anyone give me an advice how can i build and watch scss files with webpack 3 ?

You have used some of the loader configs that suppose to be for webpack 1.
That section of the config:
loaders: [
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style-loader',
'css?minimize!postcss!sass')
},
{
test: /\.(eot|woff|woff2|ttf|svg)(\?\S*)?$/,
loader: 'file?name=fonts/[name].[ext]'
},
{
test: /\.(jpg|jpeg|gif|png|svg)$/,
loader: 'file?name=images/[name].[ext]'
}
],
There are breaking changes when you move to Webpack 2 (or 3).
One of them was module.loaders => module.rules.
You will need to convert that section to the new structure.
In addition, ExtractTextPlugin changes it config style as well, please read it README.

How to uglify javascript using webpack

Here is my webpack config:
var path = require('path');
var webpack = require('webpack');
var CompressionPlugin = require("compression-webpack-plugin");
const UglifyJSPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
entry: './index.js',
output: {
path: __dirname,
filename: 'public_html/assets/js/bundle.js'
},
resolveLoader: {
modules: ["node_modules"]
},
module: {
rules: [
{
enforce: 'pre',
test: /\.tag$/,
exclude: /node_modules/,
loader: 'riotjs-loader',
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
presets: [
'es2015',
],
"babelrc": false
}
},
{
test: /\.css$/,
use: [
{
loader: "css-loader",
options: {
modules: false
}
}
]
}
]
},
plugins: [
new webpack.LoaderOptionsPlugin({debug: true}),
new UglifyJSPlugin(),
new webpack.ProvidePlugin({
riot: 'riot'
}),
new CompressionPlugin({
asset: "[path].gz[query]",
algorithm: "gzip",
test: /\.(js|html)$/,
threshold: 10240,
minRatio: 0.8
})
]
}
This completely uglifies the bundle js but the problem is global variables references are lost. I mean the properties of global object DataMixin are lost.
For example, inside index.html I have:
<script>
window.onload = function () {
DataMixin.get_data_page_load(); //DataMixin defined in other js file
};
</script>
After uglifying, I get error:
Cannot read property 'get_data_page_load' of undefined
How do I fix this? I am using webpack 2.

For webpack 2 you don't need to install the external uglify plugin.
In your webpack config replace this new UglifyJSPlugin(), with the following:
new webpack.optimize.UglifyJsPlugin({
sourceMap: true,
minimize: true,
compressor: {
warnings: false,
},
}),

Removing presets fixed it but also had to remove arrow functions from my code.
Here is the solution I found: http://www.rootscopeblog.com/blog/post?=uglifying-riotjs-files-using-webpack-2

Module not found: Error: Cannot resolve module 'module'

I want to load module from variable string
var abc = './../containers/BlankContainer';
require(abc);
but it cannot find module, so I install 'require-from-string' module from npm.
Now when I build it's giving error
ERROR in ./~/require-from-string/index.js
Module not found: Error: Cannot resolve module 'module' in D:\Nilay\RnD\node_modules\require-from-string

I found it is webpack issue, here is my webpack config:
const webpack = require('webpack');
const path = require('path');
const ExtractTextPlugin = require('extract-text-webpack-plugin')
var entry = [path.resolve(__dirname, 'app/bootstrap.js')];
var output = {
path: path.resolve(__dirname, 'public/dist'),
filename: 'bundle-[name].js',
publicPath: "dist/"
};
var modules = {

How can I resolve it?
