Express.js - purpose behind ./bin/www

Question

Simple question:

In regards to Express's generator, what is the purpose and benefit behind abstracting app.listen() out of the app.js file and into the ./bin/www file ?

Simple but cool, you actually dig out into express stuff and check things out. — Zlatko, Dec 24 '14 at 00:10

This makes the app easily testable with supertest, for one thing. This way you can leave your dev server running and still run tests without worrying about TCP port conflicts.
