KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web.
|
||||
|
||||
* **Fast:** KaTeX renders its math synchronously and doesn't need to reflow the page. See how it compares to a competitor in [this speed test](https://www.intmath.com/cg5/katex-mathjax-comparison.php).
|
||||
* **Print quality:** KaTeX's layout is based on Donald Knuth's TeX, the gold standard for math typesetting.
|
||||
* **Self contained:** KaTeX has no dependencies and can easily be bundled with your website resources.
|
||||
* **Server side rendering:** KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML.
|
||||
|
||||
KaTeX is compatible with all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 11.
|
||||
|
||||
KaTeX supports much (but not all) of LaTeX and many LaTeX packages. See the [list of supported functions](https://katex.org/docs/supported.html).
|
||||
|
||||
Try out KaTeX [on the demo page](https://katex.org/#demo)!
|
||||
|
||||
## Getting started
|
||||
|
||||
### Starter template
|
||||
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<!-- KaTeX requires the use of the HTML5 doctype. Without it, KaTeX may not render properly -->
|
||||
<html>
|
||||
<head>
|
||||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.21/dist/katex.min.css" integrity="sha384-zh0CIslj+VczCZtlzBcjt5ppRcsAmDnRem7ESsYwWwg3m/OaJ2l4x7YBZl9Kxxib" crossorigin="anonymous">
|
||||
|
||||
<!-- The loading of KaTeX is deferred to speed up page rendering -->
|
||||
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.21/dist/katex.min.js" integrity="sha384-Rma6DA2IPUwhNxmrB/7S3Tno0YY7sFu9WSYMCuulLhIqYSGZ2gKCJWIqhBWqMQfh" crossorigin="anonymous"></script>
|
||||
|
||||
<!-- To automatically render math in text elements, include the auto-render extension: -->
|
||||
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.21/dist/contrib/auto-render.min.js" integrity="sha384-hCXGrW6PitJEwbkoStFjeJxv+fSOOQKOPbJxSfM6G5sWZjAyWhXiTIIAmQqnlLlh" crossorigin="anonymous"
|
||||
onload="renderMathInElement(document.body);"></script>
|
||||
</head>
|
||||
...
|
||||
</html>
|
||||
```
|
||||
|
||||
You can also [download KaTeX](https://github.com/KaTeX/KaTeX/releases) and host it yourself.
|
||||
|
||||
For details on how to configure auto-render extension, refer to [the documentation](https://katex.org/docs/autorender.html).
|
||||
|
||||
### API
|
||||
|
||||
Call `katex.render` to render a TeX expression directly into a DOM element.
|
||||
For example:
|
||||
|
||||
```js
|
||||
katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, {
|
||||
throwOnError: false
|
||||
});
|
||||
```
|
||||
|
||||
Call `katex.renderToString` to generate an HTML string of the rendered math,
|
||||
e.g., for server-side rendering. For example:
|
||||
|
||||
```js
|
||||
var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
|
||||
throwOnError: false
|
||||
});
|
||||
// '<span class="katex">...</span>'
|
||||
```
|
||||
|
||||
Make sure to include the CSS and font files in both cases.
|
||||
If you are doing all rendering on the server, there is no need to include the
|
||||
JavaScript on the client.
|
||||
|
||||
The examples above use the `throwOnError: false` option, which renders invalid
|
||||
inputs as the TeX source code in red (by default), with the error message as
|
||||
hover text. For other available options, see the
|
||||
[API documentation](https://katex.org/docs/api.html),
|
||||
[options documentation](https://katex.org/docs/options.html), and
|
||||
[handling errors documentation](https://katex.org/docs/error.html).
