swimlib

From Libre Aquatics Wiki, the free aquatics reference

This article is a stub. swimlib is an open-source TypeScript library with no runtime dependencies that reads and writes the swimming interchange formats, covering SDIF, HY3, EV3, REC and STD/ST2, and reading CL2 by relaxing its SDIF parser.

It is the modern counterpart to the volunteer reverse-engineering that documented Hy-Tek’s formats in the first place; see the software overview for what this section covers.
