Do not respond to rendering on Webpack Dev server

I had this work, I don’t remember what I changed, and now the page loads, but does not respond to the screen. I don’t know where the error is. No errors occur when I run webpack -m followed by npm start

the webapp folder looks like this ...

  • {app} - App.js
  • {} public - bundle.js - index.html
  • webpack.config.js
  • .babelrc
  • package.json

here are the important files

Webpack

module.exports = {
  entry: './app/App.js',
  output: {
    path: './public',
    filename: 'bundle.js',
  },
  devServer: {
      inline:true,
      contentBase: './public',
      port: 3333
    },
  module: {
    loaders: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: 'babel'
      }
    ]
  }
}

package.json

{
  "name": "newaccount",
  "version": "1.0.0",
  "description": "a form submission for new accounts",
  "main": "App.js",
  "scripts": {
    "start": "webpack-dev-server"
  },
  "author": "---",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.1",
    "react-dom": "^15.4.1",
    "react-router": "^3.0.0"
  },
  "devDependencies": {
    "babel-core": "^6.18.2",
    "babel-loader": "^6.2.8",
    "babel-preset-es2015": "^6.18.0",
    "babel-preset-react": "^6.16.0",
    "html-webpack-plugin": "^2.24.1",
    "webpack": "^1.13.3",
    "webpack-dev-server": "^1.16.2"
  }
}

.babelrc

{
  "presets": [
          "es2015",
          "react"
    ]
}

App.js

import React, { Component } from 'react';
import ReactDOM from 'react-dom';



class Testing extends Component {
    render() {
        return (
            <div>
                <h3>JUST A TEST</h3>
            </div>
        )
    }
}

ReactDOM.render(<Testing />, document.getElementById('app'));

I have ever tried to do component testing ES6 const like ...

const Testing = () => return <div><h3>JUST A TEST</h3></div>

and still cannot get anything to be displayed on the local host: 3333 or the full path from my computer.

Thanks for any help
