Config Library for loading JSON config on both server and client side without automatic UI

[rocky minnow]

I would like to to load the data for configuring stats and powers of weapons and make them so its also fixing itself when something is missing without overwriting whole file. I allready wrote a config system, but half of the code is really buggy. I would like to have the configs loaded from the config directory. Is there any good Java/Kotlin library doing that?

You could use plain old gson. It's included in spongepowered mixins.

(and minecraft and fabric loader)

you probably dont want to use the one thats shadowed in mixin
