protect my JavaScript library

Hi, all,

if I have a JavaScript library and I want to protect it by adding license or key, what is the best approach?

 I am thinking about adding a license key in the back-end and the JS library always need to ask the server for the key.

 Then, the server returns the key. If the key matches, the JS library will work. Is there a better approach?
