Building from Source

To build you will need Git, Node.js 6.9 or later, and Yarn.

Clone a copy of the GitHub source repository:

git clone https://github.com/KaTeX/KaTeX.git
cd KaTeX

Then install dependencies and run build script:

yarn
yarn build

If you'd like to use the built KaTeX in other projects, install the package by specifying the path:

yarn add /path/to/KaTeX
# or using npm
npm install /path/to/KaTeX

You can manually download the package and source code from GitHub releases.

Importing

KaTeX is exported as a CommonJS module, which can be imported using require:

const katex = require('katex');

If you're using a module loader, transpiler, or bundler that supports interoperability between ECMAScript module and CommonJS module, you can use import:

import katex from 'katex';

KaTeX also provides an ECMAScript module:

import katex from 'katex/dist/katex.mjs'

The ES module contains ES6 syntaxes and features, and may need transpiling to use in old environments:
