@misode Hi, do you consider using a module like lz4 or what else would be an acceptable solution for you?

[misode]

It looks like the library you linked does do what we need here and seems to be the most popular one from the few that I found. The repo is archived but I guess that's not a huge deal.

If anyone is up for doing this, the package would need to be integrated and then tested in both nodejs and the browser on some region files that were made by a vanilla server using this compression mode.
