Webpack doesn't correctly load my files - reactjs

Question

I'm totally new to webpack and I'm doing my first configuration for a new project.
I'm trying to load my jsx/scss file but I've this problem:
var path = require('path');
var webpack = require('webpack');
var autoprefixer = require('autoprefixer');
var node_modules_dir = path.resolve(__dirname, 'node_modules');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
var HtmlWebpackPlugin = require('html-webpack-plugin');
var cssExtractTextPlugin = new ExtractTextPlugin("css", "index.css");
var staticPrefix = path.join(__dirname, 'src')
var distPath = path.join(__dirname, 'dist')
module.exports = {
devtool: 'eval',
//context: path.join(__dirname, staticPrefix),
entry: {
'app': ['webpack-hot-middleware/client', path.join(__dirname, 'src/app.jsx')],
'vendor': [
'bootstrap/js/dropdown',
'bootstrap/js/tab',
'bootstrap/js/tooltip',
'bootstrap/js/alert',
'jquery',
'react-router',
'react-bootstrap'
],
'myapp': path.join(__dirname, 'src/stylesheets/base.scss') //'stylesheets/base.scss'
},
output: {
path: distPath,
filename: '[name].js',
libraryTarget: 'var',
library: 'exports',
publicPath: '/static/'
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin(),
new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.js'),
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery',
'root.jQuery': 'jquery'
}),
new ExtractTextPlugin('[name].css')
],
module: {
loaders: [
{
test: /\.js$/,
loader: ['babel'],
include: path.join(__dirname, staticPrefix),
exclude: /(vendor|node_modules)/
},
{
test: /\.jsx$/,
loader: ['babel'],
include: path.join(__dirname, staticPrefix),
exclude: /(vendor|node_modules)/
},
{
test: /\.scss$/,
include: path.join(__dirname, staticPrefix),
loader: ExtractTextPlugin.extract('style-loader', 'css-loader!sass-loader-loader')
},
{
test: /\.(woff|woff2|ttf|eot|svg|png|gif|ico|jpg)($|\?)/,
loader: 'file-loader?name=' + '[name].[ext]'
}
]
},
postcss: function() {
return [autoprefixer];
},
resolve: {
modulesDirectories: [path.join(__dirname, staticPrefix), 'node_modules'],
extensions: ['', '.jsx', '.js']
},
};
The problem is that when I run: node_modules/.bin/webpack --config=webpack.config.dev it give me 2 errors:
ERROR in ./src/app.jsx
Module parse failed: /Users/work/Desktop/myapp-client/src/app.jsx Line 1: Unexpected token
You may need an appropriate loader to handle this file type.
| import React from 'react';
| console.log('hello!’);

# multi app
ERROR in ./src/stylesheets/base.scss
Module parse failed: /Users/work/Desktop/myapp-client/src/stylesheets/base.scss Line 1: Unexpected token {

| body {
| background: black;
| }
Where I'm doing wrong ?

With babel 6 you need to include the babel react preset to transpile your .jsx files. You also need to add the babel es2015 preset to transpile ES2015, i.e. ES6, syntax:
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /(node_modules)/,
loader: 'babel',
query: {
presets:[ 'react', 'es2015' ]
}
}
]
}
On a side note, if you tweak your regex in the test key, you don't need two loader entries (for the .js and .jsx files).
Make sure you install these presets separately:
npm i -D babel-preset-es2015 babel-preset-react
