Feature request: browser version / React component

[skrat]

It would be great if fSpy would have online version. Additionally, it seems that there's nothing preventing it from being re-usable React component or JS library. Hosted at npmjs.com. That would be great, I could immediately use it in software that I'm working on.

Thanks for all the great work, and if there is any interest in this, I'd love to help making it happen.
