# mathjax-node [](https://travis-ci.org/mathjax/MathJax-node)
|
||
|
|
|
||
|
|
This repository contains files that provide APIs to call [MathJax](https://github.com/mathjax/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](http://xmlgraphics.apache.org/batik/download.html) 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.js` is optimized for processing single equations.
|
||
|
|
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
// a simple TeX-input example
|
||
|
|
var mjAPI = require("mathjax-node/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.js` is optimized for handling full HTML pages.
|
||
|
|
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var mjAPI = require("mathjax-node/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);
|
||
|
|
});
|
||
|
|
```
