Shared Library between SCA and NetSuite

In NetSuite, I've built several libraries which are wrapped in JavaScript namespaces. This has worked great for reusing code. Now we are implementing SCA and I'm working with another developer in our organization who's doing the SCA coding. Is there a way that I can make my NetSuite libraries available on the SCA side? This is so easy in NetSuite, but I don't see how this is done in SCA.

This might be overkill, but here's an example.

 // example_lib.js shared library  var example_lib = {      Hello: "Hello World";  }    // after including example_lib.js in an SCA service  var whatever = example_lib.Hello;    // after including example_lib.js in a NetSuite Restlet or User Event  var whatever = example_lib.Hello;
