Mml-to-chtml NPM

mml-to-chtml

This MathJax wrapper converts Mathematical Markup Language (MML) to Compact Hypertext Markup Language (CHTML). This package doesn't use any webworkers, webviews ; so It can be used for your NodeJS, React and React Native projects.

This project is still in its early development stages.

For any bugs, typos, errors, feel free to open an issue on the associated Github repository.

Installation

npm install mml-to-chtml --save
