/* A quick reminder on how to use Promises with Node and Express in order to run potentially
 * time-consuming jobs asynchronously (assuming the jobs are able to run in the background thanks to
 * libuv and actually return Promises).
 *
 * Start the server, navigate to /startjob, then refresh a few times, the job should be in progress.
 * You can navigate elsewhere in the "app" in other browser tabs in the meanwhile (/). After about
 * 20s, you should get a result by refreshing the tab where you originally submitted the job.
 *
 * I hope this pattern will be useful e.g. for processing images with the `sharp` library (see
 * <http://sharp.dimens.io>).

Handling Errors

Express.js makes it a breeze to handle errors in your routes.

Express lets you centralizes your error-handling through middleware.

Let's look at patterns for how to get the most out of your error-handling.

First, our error-handling middleware looks like this:

function MyResponsiveComponent() {
  const width = useWindowWidth(); // Our custom Hook
  return (
    <p>Window width is {width}</p>
  );
}

<script type="x-shader/x-vertex" id="vertexshader">

  attribute float size;
  attribute vec3 customColor;
  varying vec3 vColor;

  void main() {

    vColor = customColor;
    vec4 mvPosition = modelViewMatrix * vec4( position, 1.0 );
