|--------------------------------------------------------------------------
| webpack.config.js -- Configuration for Webpack
|--------------------------------------------------------------------------
|
| Webpack turns all the clientside HTML, CSS, Javascript into one bundle.js file.
| This is done for performance reasons, as well as for compatability reasons.
|
| You do not have to worry about this file, except for proxy section below.
| All proxies does is route traffic from the hotloader to the backend.
| You must define explicity all routes here, as we do for the /api/* routes.
|
| The rest of this file tell webpack which types of files to bundle (in the rules).
| In addition, it also uses babel to transpile your javascript into code all browsers can use.
| see https://babeljs.io/docs/en/ if this interests you!
