Bundling module for NODE.JS

ASP.NET MVC 4 has brought amazing tool for bundling multiple stylesheets or javascripts into one like this:

bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(
                    "~/Content/themes/base/jquery.ui.core.css",
                    "~/Content/themes/base/jquery.ui.datepicker.css",
                    "~/Content/themes/base/jquery.ui.theme.css"));

Does NODE.JS have any modules to fulfil the same task - to bundle client javascript libraries into one? I've seen tools like browserify, uglifier, etc. but these require manual invocation of console commands (or may I have missed something?). Meanwhile, it would be nice to eliminate that excessive step and have middleware that could be easily integrated into express.js application, for instance.
