spiro-js is a JavaScript / TypeScript port of Raph Levien’s Spiro, an interpolating spline based on spirals, with extended features for per-knot callbacks and quadratic output.
Credits for Spiro to Raph Levien, and also to others that translated his work to other programming languages that made my port easier.
