I uglify my code to cut down file size and not because I worry about protecting my code from copying because very few applications really contain something novel enough that a motivated person couldn't copy you even without access to code. Instead, focus on providing better value to your customers. If you do have some novel piece of functionality that you absolutely must protect, implement it on the server.
