mathpix-markdown-it
Advanced tools
Mathpix-markdown-it is an open source implementation of the mathpix-markdown spec written in Typescript. It relies on the following open source libraries: MathJax v3 (to render math with SVGs), markdown-it (for standard Markdown parsing)
mathpix-markdown is a Markdown dialect which addresses limitations inherent in standard Markdown that appear when communicating scientific and mathematical information:
Mathpix Markdown addresses these limitations by adding support for the following standard Latex syntax elements which are already familiar to the scientific community:
\( <latex math> \)\[ <latex math> \] or $$ <math> $$\begin{tabular} ... \end{tabular}\begin{figure} \caption{...} ... \end{figure}\begin{elem} ... \end{elem} and \begin{elem*} ... \end{elem*} where elem=equation|align|split|gather\label, \ref, \eqref, \tag\title{...}, \author{...}, \begin{abstract}...\end{abstract}, \section{Section Title}, \subsection{Section Title}, \subsubsection{Section Title}, \textit{italicized text}, \textbf{bold text}, \url{link}mathpix-markdown-it is an open source implementation of the mathpix-markdown spec written in Typescript.
It relies on the following open source libraries:
npm usage:
$ npm install mathpix-markdown-it
yarn usage:
$ yarn add mathpix-markdown-it
We provide React components which make rendering of mathpix-markdown-it easy for React applications: Full example
import {MathpixMarkdown, MathpixLoader} from 'mathpix-markdown-it';
class App extends Component {
render() {
return (
<MathpixLoader>
<MathpixMarkdown text="\\(ax^2 + bx + c = 0\\)"/>
<MathpixMarkdown text="$x = \frac { - b \pm \sqrt { b ^ { 2 } - 4 a c } } { 2 a }$"/>
...
</MathpixLoader>
);
}
}
import * as React from 'react';
import { MathpixMarkdownModel as MM } from 'mathpix-markdown-it';
class App extends React.Component {
componentDidMount() {
const elStyle = document.getElementById('Mathpix-styles');
if (!elStyle) {
const style = document.createElement("style");
style.setAttribute("id", "Mathpix-styles");
style.innerHTML = MM.getMathpixFontsStyle() + MM.getMathpixStyle(true);
document.head.appendChild(style);
}
}
render() {
const html = MM.render('$x = \\frac { - b \\pm \\sqrt { b ^ { 2 } - 4 a c } } { 2 a }$');
return (
<div className="App">
<div className="content" dangerouslySetInnerHTML={{__html: html}}></div>
</div>
)
}
}
export default App;
class ConvertForm extends React.Component {
constructor(props) {
super(props);
this.state = {
value: '\\[\n' +
'y = \\frac { \\sum _ { i } w _ { i } y _ { i } } { \\sum _ { i } w _ { i } } , i = 1,2 \\ldots k\n' +
'\\]',
result: ''
};
this.handleChange = this.handleChange.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleChange(event) {
this.setState({value: event.target.value});
}
handleSubmit(event) {
event.preventDefault();
this.setState({result: MM.markdownToHTML(this.state.value)})
}
render() {
return (
<div>
<form onSubmit={this.handleSubmit}>
<h1>Input Text with Latex:</h1>
<textarea value={this.state.value} onChange={this.handleChange} />
<input type="submit" value="Convert" />
</form>
<div id='preview-content' dangerouslySetInnerHTML={{__html: this.state.result}}/>
</div>
);
}
}
Rendering methods have the ability to convert Latex representation to such formats as: mathml, asciimath, tsv
const options = {
outMath: {
include_mathml: true,
include_asciimath: true,
include_latex: true,
include_svg: true,
include_tsv: true,
include_table_html: true,
}
};
const html = MM.markdownToHTML(`$x^x$`, options);
markdownToHTML() returns an HTML string that will contain the formats specified in the options.
For Latex formulas, the result will be:
<span class="math-block">
<mathml style="display: none">...</mathml>
<asciimath style="display: none">...</asciimath>
<latex style="display: none">...</latex>
<mjx-comtainer class="MathJax" jax="SVG">..</mjx-comtainer>
</span>
For tabular, the result will be:
<div class="table_ tabular">
<table id="tabular">...</table>
<tsv style="display: none">...</tsv>
</div>
Then calling the parseMarkdownByHTML(html) method will return all formats as a list from the incoming html string.
For Latex formulas:
[
{
"type": "mathml",
"value": "<math>...</math>"
},
{
"type": "asciimath",
"value": "x^(x)"
},

"type": "latex",

Before using mathpix-markdown-it in node applications, you should define global variables
const Window = require('window');
const window = new Window();
global.window = window;
global.document = window.document;
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
global.DOMParser = new JSDOM().window.DOMParser;
It prints html to the console for string \\(ax^2 + bx + c = 0\\)
$ npm install mathpix-markdown-it jsdom window
const {MathpixMarkdownModel} = require('mathpix-markdown-it');
const Window = require('window');
const window = new Window();
global.window = window;
global.document = window.document;
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
global.DOMParser = new JSDOM().window.DOMParser;
const text = `\\(ax^2 + bx + c = 0\\)`;
const options = {
htmlTags: true,
width: 800
};
const htmlMM = MathpixMarkdownModel.markdownToHTML(text, options);
console.log(htmlMM);

| React components | props | description |
|---|---|---|
MathpixLoader | Loads styles | |
MathpixMarkdown | props | Renders input text to html element |
The MathpixMarkdown React element accepts the following props:
| prop | type default | description |
|---|---|---|
text | sting | string that will be converted |
alignMathBlock | string center | aligns math-block by this params |
display | string block | block - the whole space, inline-block - renders in its actual size |
showTimeLog | boolean false | shows execution time in console |
isDisableFancy | boolean false | true - disables processing of special characters (Example: (c), +, - ) |
