Features

• Minifying JSON files, using serde-json, and removing comments

lib.rs:

MC-Repack is initially built as a CLI app, but can also be used as a library. This crate contains methods necessary to work with files that need optimizations.

This crate considers that the repacked files are used in Minecraft mods. You can still use the library for other types, like Android or Gradle files.
