How do I change LaTeX to MathML using MathJax in Node.js?

I'm trying to render math equations from user input server side using MathJax in Node.js. I'm using a separate library (mathjs) to turn the input into LaTeX, but after spending an hour looking at the MathJax docs I'm no closer to turning the LaTeX into MathML.

I'm assuming I'd be using the mathjax package on NPM, and then use the MathJax.InputJax and MathJax.OutputJax classes to do the processing, but I've got no idea how to put everything together.

(In case anyone is wondering, I'm using a CSS file to polyfill MathML, rather than load MathJax in the browser and cause a delay while the processing happens.)

Solution

  • You want to use MathJax-node for this. It is set up to run MathJax server-side. There are a number of example command-line tools in the bin directory. You could also hook up a web service to handle the conversion. Tim Arnold made one available as mathjax-server on npmjs.com.
