Gulp & Webpack compiling React - reactjs

Question

I am strugling with setting up basic compilation of my React project using Gulp & Webpack
Here is my Gulpfile:
function styles() {
return gulp.src('./src/less/styles.less')
.pipe(less())
.pipe(gulp.dest('./dist'))
.pipe(connect.reload());
}
function copyAssets() {
return gulp.src('./assets/**')
.pipe(gulpCopy('./dist/'))
.pipe(connect.reload());
}
function watchAssets() {
gulp.watch('assets/**/*', copyAssets);
gulp.watch('src/less/**/*.less', styles);
}
function webpackBuildgulp() {
return gulp.src('src/js/index.js')
.pipe(webpack(webpackConfig))
.pipe(gulp.dest('dist/'));
}
gulp.task('default', gulp.parallel(styles, copyAssets, webpackBuildgulp, server, watchAssets));
Here is my Webpack config:
module.exports = () => {
const webpackConfig = {
entry: './src/js/index.js',
module: {
rules: [{
test: /\.jsx$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['es2015', 'stage-0', 'react'],
},
},
}],
},
output: {
path: path.resolve(__dirname, '../dist'),
filename: 'app.js',
publicPath: 'http://localhost:1337/dist/',
},
resolve: {
modules: ['../src/js', 'node_modules'],
extensions: ['', '.js', 'jsx'],
},
plugins: [
new webpack.ProvidePlugin({
jQuery: 'jquery',
$: 'jquery',
}),
],
};
return webpackConfig;
};

However when I trie to compile my project typing gulp I get the following error:
Module parse failed: /src/js/index.js Unexpected token (42:2)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (42:2)
Here is the index.js file:
import ReactDOM from 'react-dom';
import React from 'react';
import { Provider } from 'react-redux';
import { Router, browserHistory } from 'react-router';
import { IntlProvider } from 'react-intl';
import ReduxToastr from 'react-redux-toastr';
import createStore from './store';
import { SIGNIN_USER, getCurrentUser } from './actions/auth';
import { getSalonsBasicInfo } from './actions/landingPage';
import { stuff } from './middleware/stuff';
import { checkSalon } from './actions/salon';
import routes from './routes';
import translations from './translations/en';
if (!window.Intl) {
require('intl');
}
const store = createStore();
const access_token = localStorage.getItem('access_token');
const refresh_token = localStorage.getItem('refresh_token');
store.dispatch({
type: INIT,
});
if (access_token || refresh_token) {
store.dispatch({
type: SIGNIN_USER,
});
store.dispatch(getCurrentUser());
store.dispatch(checkSalon());
}
localStorage.setItem('debug', false);
ReactDOM.render(
<Provider store={store}>
<div>
<ReduxToastr
timeOut={4000}
newestOnTop={false}
position="top-center"
/>
<IntlProvider locale={'en-US'} messages={translations}>
<Router history={browserHistory} routes={routes} />
</IntlProvider>
</div>
</Provider>,
document.getElementById('app'),
);
Someway, somehow, Babel fails to understand React code and doesnt compile it.
However when I run Babel manually:
babel src/js/index.js --presets es2015,react
It works perfectly.
What am I doing wrong in my Webpack configuration ?

Answer 1

Your babel-loader is only testing for .jsx files and you have saved your index as a .js file. Change test to test: /\.(js|jsx)$/, and see if that helps.
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['es2015', 'stage-0', 'react'],
},
},
}],
}
