Some differences are this uses an apache webserver rather than nginx, and this server doesn't actually update, So I smashed in eaglercraft 1.5.2 service pack 1.01.
To get this into replit, just create a repl by clicking create repl and clicking import from github. Then, copy the link of this github repository and paste it in replit.
Then, start it by clicking the start button after the repl is finished creating.
NOTE: Don't stop the server manually in the console or shell, kindly click the stop button.
