mhchem Parser

mhchemParser is a JavaScript/TypeScript library designed to convert chemical equations and physical units written in the mhchem syntax into standard LaTeX syntax. This conversion is crucial for rendering chemical notation accurately in environments that support LaTeX, such as MathJax and KaTeX. The current stable version is 4.2.1. It serves as a foundational parser, allowing developers to process mhchem input directly before feeding it into a LaTeX rendering engine. The library is actively maintained and differentiates itself by providing a robust, standalone parsing capability specifically for mhchem syntax, rather than being an integrated component of a larger rendering system. Its primary utility is for downstream software integration, enabling flexible handling of chemical typesetting.
