Build Failure while using webpack production build - reactjs

Question

I am getting Module build failed: SyntaxError: Unexpected token Error.
I am getting this error while generating production build, before applying the Webpack production build configuration the same code was working earlier when using development build. Can you suggest me what i am doing wrong in webpack.config.js
Here is the Error
ERROR in ./src/index.jsx
Module build failed: SyntaxError: Unexpected token (10:4)
client |
client | 8 |
client | 9 | const App = () => (
client | > 10 | <Provider store={store}>
client | | ^
client | 11 | <AppRoute/>
client | 12 | </Provider>
client | 13 | );
Here is my webpack.config.js file code
const path = require('path');
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const PreloadWebpackPlugin = require('preload-webpack-plugin');

const CompressionPlugin = require('compression-webpack-plugin');
const autoprefixer = require('autoprefixer');
const staticSourcePath = path.join(__dirname, 'static');
const sourcePath = path.join(__dirname, 'src');
const buildPath = path.join(__dirname, 'dist');
module.exports = {
devtool: 'source-map',
entry: {
app: path.resolve(sourcePath, 'index.jsx')
},
output: {

},

}
}),
new webpack.optimize.UglifyJsPlugin({

new HtmlWebpackPlugin({

})
],
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: [
'babel-loader'
]
},
{
test: /\.css$/,
exclude: /node_modules/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [
{ loader: 'css-loader', options: { minimize: true } },
'postcss-loader',
'sass-loader'
]
})
},
{
test: /\.(eot?.+|svg?.+|ttf?.+|otf?.+|woff?.+|woff2?.+)$/,
use: 'file-loader?name=assets/[name]-[hash].[ext]'
},
{
test: /\.(png|gif|jpg|svg)$/,
use: [
'url-loader?limit=20480&name=assets/[name]-[hash].[ext]'
],
include: staticSourcePath
}
]
}
};
And Here is my index.jsx code.
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { store } from './_helpers';
import AppRoute from './pages/approute';
import 'react-table/react-table.css';
const App = () => (
<Provider store={store}>
<AppRoute/>
</Provider>
);
ReactDOM.render(<App />, document.getElementById('app'));

Answer 1

As pointed out in a comment there has to be something with babel configuration that webpack can't transpile JSX syntax.
Check out if you have babel-preset-react installed and turned on:
"presets": [
"react"
],
Little nitpick - use caching for faster incremental builds:
{
test: /\.jsx?$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
cacheDirectory: true,
},
},
},

Answer 2

Final update in webpack.config.js
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
cacheDirectory: true,
presets: ['react', 'es2015', 'stage-3']
}
}
