how to change server ip address and after generating dist contents

[smart987]

Is there any way to give ability to the client to change the server ip address after we have given dist contents to the client. As of now I have given .constant('serverUrl', "http://x.y.z.a:6061"); in index.constant.js and referring serverUrl in my services. But the problem is now, after I have given dist (gulp serve:dist) folder contents to the client they want to change their server ip address. Is there any provision for that in this project structure?
