Because of a recent request in a piece of software I contribute to. I had a need for a NodeJS implementation of PSN. I couldn’t find any that fit the bill (outdated/only encode/etc.) So I whipped one up and thought I would share it with the public. I have tested the implementation against the examples in the psn-cpp repo. Still have some cleanup/documenting to do but for the most part it should be complete with the 2.03 PSN spec PDF.
