Typically our projects at work range from 50,000 to 200,000 depending on the scope. We've had compiled javascript files (ES6 compiled into browser standard JS) be over 100,000, so if we factor in the backend it probably adds another 20-50k on average.
Then again these are company projects so I feel it's a lot more work for a single individual to get 15k lines like you did. So bravo!
Edit: Just realized I was reading the numbers wrong, that 15k was just for rooms alone! 95k total for an individual project is insanely awesome! Bravo
