What are the best ways to avoid front-end debugging when doing web development?

I'm coming back to web development after a long break of 8 years. Needless to say, a lot has changed.

I'm planning to start a new web dev project and want to choose swift as a server side language. Regardless of which server side language is chosen, eventually the front end code will have to be generated (html/css/js).

And debugging will be required from the front end which is the part of web development that I loath.

Are there ways where I can minimize front end development/debugging as much as possible and focus just on the server side?
