tex2typst.js

JavaScript library for conversion between TeX/LaTeX and Typst math code.

Despite the name tex2typst due to the initial goal of converting TeX to Typst, the library can also convert Typst to TeX since version 0.3.0.

Try it online

A Web UI wrapper is available at https://qwinsi.github.io/tex2typst-webapp/.

Installation

Installing it in a Node.js project

npm install tex2typst

Or just loading it in a web page

<script src="https://cdn.jsdelivr.net/npm/tex2typst@0.3.0/dist/tex2typst.min.js"></script>
<!-- or  -->
<script src="https://unpkg.com/tex2typst@0.3.0/dist/tex2typst.min.js"></script>

Replace 0.3.0 with the latest version number in case this README is outdated.

Usage

import { tex2typst, typst2tex } from 'tex2typst';

let tex = "e \\overset{\\text{def}}{=} \\lim_{{n \\to \\infty}} \left(1 + \\frac{1}{n}\\right)^n";
let typst = tex2typst(tex);
console.log(typst);
// e eq.def lim_(n -> infinity) (1 + 1/n)^n

let tex_recovered = typst2tex(typst);
console.log(tex_recovered);
// e \overset{\text{def}}{=} \lim_{n \rightarrow \infty} \left(1 + \frac{1}{n} \right)^n

If you are using the library in a web page via a <script> tag, you don't need the line of import, function tex2typst and typst2tex should be available in the global scope.

tex2typst.js supports some advanced options to customize the conversion. For details, please refer to the API Reference.
