Initially (about 15 years ago - it was my first ever open source library!) it was based on Astronomy Answers articles that are thankfully still live at https://www.aa.quae.nl/en/reken/zonpositie.html, but v2.0 specifically was rewritten to use the approach described in Jean Meeus' Astronomical Algorithms book.
I did a similar one recently but have not been able to validate it's calculations against any other source. Thanks for posting the link to yours when I get time I'll compare and see if they match up. https://git.mikedilger.com/mikedilger/sunangle
