Custom reimplementation of Three.js SkeletonHelper that allows to edit properties such as linewidth that are otherwise ignored by WebGL. The interesting file here is src/customSkeletonHelper.js.
To use it in your project, simply copy that file and import the SkeletonHelper like: import {SkeletonHelper} from './customSkeletonHelper'; Then use that version instead of the one from Three. Properties can be passed to the object when instantiating it or through one of the Set methods.
