libstub is a tiny UMD module that uses the global namespace to dynamically link dependencies between JS bundles.
Why? To help link together JS packages, independent of how they were built.
// include libstub before these files
// file a.js, wants to export module a
var a = {};
libstub.export('a', a);
// file b.js, wants to import a and export b
var a = libstub.import('a');
var b = {};
libstub.export('b', b);
// file c.js, wants to import a and b.
var a = libstub.import('a');
var b = libstub.import('b');
