Was developing a game with a node.js express framework which required a way to store scores. I decided to store them using players' repl.it names (as the game was designed to be played by repl.it users)
I came across an issue whilst creating the authentication. A can't actually test if a username exists in the repl.it database, as any url with an incorrect username Example: "https://repl.it/@completlyfake" just returns the built-in page that says 404, and
XMLHttpRequests (due to security reasons) are blocked when access is attempted across domains. I was wondering if it's possible to authenticate against the repl.it user database.
Surprisingly enough, it took me like 5 attempts to find a user that didn't actually exist (there's a user called "notauser")
Why do you need to test if a username exists if you're using the automatic auth? you can be sure it exist
@Geocube101 Take a look at this post by @mat1, https://repl.it/talk/learn/Authenticating-users-with-Replit-Auth/23460. It is for python + flask but you should be able to convert it to node.js+express, if not you can always ask for help in the community.
