React - Module Build Failed

Question

I'm trying to a basic React setup with Webpack, but currently getting this console error on the html I'm trying to render.

Not sure why, any ideas?

Module build failed: SyntaxError:

Javascript

import React from "react";
import { render } from "react-dom";

class App extends React.Component {
    render() {
        return (
            <p>h</p>
        )
    }
}

render(<App/>, document.getElementById('main'));

Webpack Config

const webpack = require('webpack');
const nodeEnv = process.env.NODE_ENV || "production";

module.exports = {
    devtool: "source-map",
    entry: {
        filename: "./index.js"
    },
    output: {
        filename: "build/bundle.js"
    },
    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader',
                query: {
                    presets: ['es2015-native-modules']
                }
            }
        ]
    },
    plugins: [
        new webpack.optimize.UglifyJsPlugin({
            compress: { warnings: false },
            output: { comments: false },
            sourcemap: true
        }),
        new webpack.DefinePlugin({
            'process.env': { NODE_ENV: JSON.stringify(nodeEnv
            )}
        })
    ]
}

You need babel react preset, and I see you use strange preset now, use es2015 instead

Thanks for this. For anyone wondering I uninstalled 'babel-preset-es2015-native-modules' and installed 'babel-preset-es2015' instead and changed my webpack.config.js to 'es2015' instead of 'es2015-native-modules'. I also installed 'babel-preset-react' and added that in my presets in webpack.config.js.
