AAccess CRXDE and upload the files through the interface.
BMake the changes in CRXDE create a content package, download it, and expand it into the working directory after each change.

The JavaScript is NOT present in the Client Library when it is loaded.
What should a developer do to resolve this issue?
AAdd #base=js as the first line in the js.txt file.
