## Libraries

These libraries are maintained by third-parties.

### AsciiMath

If you want to render math written in [AsciiMath](http://asciimath.org/),
you'll need to first convert AsciiMath into LaTeX input, then call KaTeX.

- [asciimath2tex](https://github.com/christianp/asciimath2tex): Converts AsciiMath to TeX, with KaTeX in mind

### Android

- [KaTeXView](https://github.com/judemanutd/KaTeXView): An android library that uses Khan Academy KaTeX for TeX math rendering.

### Angular2+

- [ng-katex](https://github.com/garciparedes/ng-katex): Angular module to write beautiful math expressions with TeX syntax boosted by KaTeX library

### Canvas

- [canvas-latex](https://github.com/CurriculumAssociates/canvas-latex): Renders mathematical expressions on HTML5's canvas element. Supports popular libraries like: CreateJS, and PIXI.

### iOS

- [react-katex](https://github.com/talyssonoc/react-katex): React components that use KaTeX to typeset math expressions

### Ruby

- [katex-ruby](https://github.com/glebm/katex-ruby): Provides server-side rendering and integration with popular Ruby web frameworks (Rails, Hanami, and anything that uses Sprockets).

### Rust

- [katex-rs](https://github.com/xu-cheng/katex-rs): Rust bindings to provide server-side rendering.

### Sphinx

### Web-Components

- [katex-element](https://github.com/georges-gomes/katex-element): KaTeX wrapped in a custom element. Simply use `<katex-element>` in HTML - framework independent.
- [katex-expression](https://github.com/navsgh/katex-expression): A web component/custom element (built with Stencil) to render KaTeX expressions. Stencil builds web components that run natively or near-natively in all widely used desktop and mobile browsers. Stencil uses a dynamic loader to load the custom elements polyfill only on browsers that need it.

### Wechat Mini Program
