A simple application to convert server worlds to singleplayer game saves. Spigot and other minecraft server platforms save worlds in separate folders (world, world_nether, world_the_end). Conversely, vanilla Minecraft saves games in a single folder. The WorldConverter
class merges the necessary data into a single folder to facilitate singleplayer world use.
First, in the project directory, run npm install
node converter.js --input [world world_nether world_the_end] --output [converted_world]
