[Question] source-maps with css or sass?

See original GitHub issue

Hi,

I am using sass-loader to compile sass code. Can we have the source-map to trace back the source file with webpack for sass?

Currently, I setup Sass-loader by

 { test: /\.scss/, loader: "style-loader!sass-loader?outputStyle=expanded" },

with

    cache: true,
    debug: true,
    devtool: 'source-map',
    'output-pathinfo': true,

Is it possible to trace back the source sass file in chrome dev tools?

This works for me:

{ test: /\.scss$/, loader: ExtractTextPlugin.extract('style-loader',
 'css-loader?sourceMap!sass-loader?outputStyle=expanded&sourceMap=true&sourceMapContents=true') }

I was able to get it working by doing the following:

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    entry: [
        path.join(__dirname, 'src/index')
    ],
    output: {
        path: path.join(__dirname, 'dist'),
        publicPath: "/dist",
        filename: 'js/bundle.js'
    },
    devtool: 'source-map',
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /(node_modules|bower_components)/,
                loader: 'babel-loader',
                query: {
                    presets: [ 'es2015' ],
                    plugins: [ 'transform-runtime' ]
                }
            },
            {
                test: /(\.scss|\.css)$/,
                use: ExtractTextPlugin.extract({
                    fallback: 'style-loader',
                    use: [
                        {
                            loader: 'css-loader',
                            options: {
                                sourceMap: true
                            }
                        },
                        {
                            loader: 'sass-loader',

                                outFile: 'css/bundle.css',
                                outputStyle: 'expanded',
                            }
                        }
                    ],
                })
            },
            {
