Formatting rules used in library

[corpooo]

Hello, guys

I forked this repo in order to add some functionality and I want to open a PR in case that feature is wanted in the library.

While working on said feature, the formatting got messed up and I just can't find a prettier config or any kind of guide regarding the formatting, I would appreciate it a lot if someone could tell me what formatting rules are used in the project.

Thanks!
