Can I tell foreman to reload the web app every time a request is made so I can develop decently?

A web app I am writing in JavaScript using node.js. I use Foreman, but I don't want to manually restart the server every time I change my code. Can I tell Foreman to reload the entire web app before handling an HTTP request (i.e. restart the node process)?

Here's an adjusted version of Pendlepants solution. Foreman looks for an .env file to read environment variables. Rather than adding a wrapper, you can just have Foreman switch what command it uses to start things up:

In .env:

WEB=node app.js

In dev.env:

WEB=supervisor app.js

In your Procfile:

web: $WEB

By default, Foreman will read from .env (in Production), but in DEV just run this:

foreman start -e dev.env
