Express.js - How can I get the number of defined routes?

Question

If I had defined a bunch of routes and wanted to get the total number of routes setup at any point, how would I do this?

I cannot put a counter inside each route as they are spread out though-out the application. I am looking to do this via the Express.js API. I have had a look though the documentation but was unable to find anything.

Depends on Express version

3.x

console.log(app.routes.length);

4.x

console.log(app._router.stack.length);
