I had to do another fork from junmers repository to release a version with fpoint to npm.
forked from Javascript Clipper (FPoint project)
The Javascript Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons.
Javascript Clipper is a port of Angus Johnson's Clipper library: https://sourceforge.net/projects/polyclipping/
