What is katex?

KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. It provides a way to display mathematical notation in web pages, supporting a wide range of TeX functions and symbols.

What are katex's main functionalities?

Render TeX to HTML

This feature allows you to convert TeX expressions into HTML. The `renderToString` method takes a TeX string and returns an HTML string that can be inserted into a web page.

const katex = require('katex');
const html = katex.renderToString('c = \pm\sqrt{a^2 + b^2}');
console.log(html);

Render TeX to DOM

This feature allows you to render TeX expressions directly into a DOM element. The `render` method takes a TeX string and a DOM element, and it updates the element's content with the rendered math.

const katex = require('katex');
const element = document.getElementById('math');
katex.render('E = mc^2', element);

Auto-render TeX in HTML

This feature automatically finds and renders all TeX expressions within a given DOM element. The `renderMathInElement` function scans the element for TeX expressions and replaces them with rendered math.

const katex = require('katex');
const renderMathInElement = require('katex/contrib/auto-render');
renderMathInElement(document.body);
