Texture Atlas for sprite materials

Hey there, I am looking for a implementation of texture atlas for sprite materials that I want to use to generate labels in a map application. I found this repo which is exactly what I am looking for: GitHub - Leeft/three-sprite-texture-atlas-manager: Helper library for three.js r126+ to programmatically build sprite texture atlases . However, this repo is outdated and is not a npm package, I’d like to have a npm package for this. Could you guys recommend such a package, for sprite materials?
