mathjax-node 
This repository contains files that provide APIs to call MathJax from node.js programs. There is an API for converting individual math expressions (in any of MathJax's input formats) into SVG images or MathML code, and there is an API for converting HTML snippets containing any of MathJax input formats into HTML snippets containing SVG or MathML.
See the comments in the individual files for more details.
The bin directory contains a collection of command-line programs for
converting among MathJax's various formats. These can be used as examples
of calling the MathJax API.
Use
npm install mathjax-node
to install mathjax-node and its dependencies.
These API's can produce PNG images, but that requires the
Batik library. It
should be installed in the batik directory. See the README file in that
directory for more details.
Getting started
mathjax-node provides two libraries, lib/mj-single.js and lib/mj-page.js. Below are two very minimal examples -- be sure to check out the examples in ./bin/ for more advanced configurations.
lib/mj-single.jsis optimized for processing single equations.
// a simple TeX-input example
var mjAPI = require("./lib/mj-single.js");
mjAPI.config({
MathJax: {
// traditional MathJax configuration
}
});
mjAPI.start();
var yourMath = 'E = mc^2';
mjAPI.typeset({
math: yourMath,
format: "TeX", // "inline-TeX", "MathML"
mml:true, // svg:true,
}, function (data) {
if (!data.errors) {console.log(data.mml)}
});lib/mj-page.jsis optimized for handling full HTML pages.
var mjAPI = require("./lib/mj-page.js");
var jsdom = require("jsdom").jsdom;
var document = jsdom("<!DOCTYPE html><html lang='en'><head><title>Test</title></head><body><h1>Let's test mj-page</h1> <p> \\[f: X \\to Y\\], where \\( X = 2^{\mathbb{N}}\\) </p></body></html>");
mjAPI.start();
mjAPI.typeset({
html: document.body.innerHTML,
renderer: "NativeMML",
inputs: ["TeX"],
xmlns: "mml"
}, function(result) {
"use strict";
document.body.innerHTML = result.html;
var HTML = "<!DOCTYPE html>\n" + document.documentElement.outerHTML.replace(/^(\n|\s)*/, "");
console.log(HTML);
});
