Express.js View “globals”

Hello Masters,

I'm using Express.js (on Node.js) and I know that you can render a view with custom data via the "locals" parameter. (res.render("template", { locals: { foo: "bar" } });)

Is there any way to have "globals"? (ie. data that's accessible to every view)

I saw view options, but that isn't recursive, so it replaces the locals I set if I use any locals with my template.

This is my use case: I want to make it so that CSS/JS files can be added on a per-page basis, and that is part of my main layout. The problem is, if I don't explicitly set those arrays on every render, I get an undefined error, so in my template I always have to do the typeof css !== "undefined" dance. Additionally, I have other select box option lists that I don't want to have to explicitly add to each of my forms.
