Syntax error while building

[Honoo]

When trying to build with webpack, it says there is a syntax error in the given src/index.js:

ERROR in ./src/index.js
Module build failed: SyntaxError: Unexpected token (5:16)

3 | import App from './views/App';
4 | 
>5 | ReactDOM.render(<App/>, document.getElementById('app'));
                     ^
 @ multi ./src/index

To solve this, it appears that additional libraries are required.

In package.json, under devDependencies:

"babel-preset-es2015": "^6.6.0",
"babel-preset-react": "^6.5.0",

In webpack.config.js, in the loaders object:

query:
{
  presets:['react', 'es2015']
}
