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](http://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.
|
||||
* **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 supports all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 9 - IE 11. More information can be found on the [list of supported commands](https://khan.github.io/KaTeX/function-support.html) and on the [wiki](https://github.com/khan/katex/wiki).
|
||||
KaTeX is compatible with all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 11.
|
||||
|
||||
## Usage
|
||||
KaTeX supports much (but not all) of LaTeX and many LaTeX packages. See the [list of supported functions](https://katex.org/docs/supported.html).
|
||||
|
||||
You can [download KaTeX](https://github.com/khan/katex/releases) and host it on your server or include the `katex.min.js` and `katex.min.css` files on your page directly from a CDN:
|
||||
Try out KaTeX [on the demo page](https://katex.org/#demo)!
|
||||
|
||||

||||
onload="renderMathInElement(document.body);"></script>
|
||||
</head>
|
||||
...
|
||||
</html>
|
||||
```
|
||||
|
||||
#### In-browser rendering
|
||||
You can also [download KaTeX](https://github.com/KaTeX/KaTeX/releases) and host it yourself.
|
||||
|
||||
Call `katex.render` with a TeX expression and a DOM element to render into:
|
||||
For details on how to configure auto-render extension, refer to [the documentation](https://katex.org/docs/autorender.html).
|
||||
|
||||
```js
|
||||
katex.render("c = \\pm\\sqrt{a^2 + b^2}", element);
|
||||
```
|
||||
|
||||
If KaTeX can't parse the expression, it throws a `katex.ParseError` error.
|
||||
|
||||
#### Server side rendering or rendering to a string
|
||||
|
||||
To generate HTML on the server or to generate an HTML string of the rendered math, you can use `katex.renderToString`:
|
||||
|
||||
```js
|
||||
var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}");
|
||||
// '<span class="katex">...</span>'
|
||||
```
|
||||
|
||||
Make sure to include the CSS and font files, but there is no need to include the JavaScript. Like `render`, `renderToString` throws if it can't parse the expression.
|
||||
|
||||
#### Security
|
||||
|
||||
Any HTML generated by KaTeX *should* be safe from `<script>` or other code
|
||||
injection attacks.
|
||||
(See `maxSize` below for preventing large width/height visual affronts.)
|
||||
Of course, it is always a good idea to sanitize the HTML, though you will need
|
||||
a rather generous whitelist (including some of SVG and MathML) to support
|
||||
all of KaTeX.
|
||||
|
||||
#### Handling errors
|
||||
|
||||
If KaTeX encounters an error (invalid or unsupported LaTeX), then it will
|
||||
throw an exception of type `katex.ParseError`. The message in this error
|
||||
includes some of the LaTeX source code, so needs to be escaped if you want
|
||||
to render it to HTML. In particular, you should convert `&`, `<`, `>`
|
||||
characters to `&`, `<`, `>` (e.g., using `_.escape`)
|
||||
before including either LaTeX source code or exception messages in your
|
||||
HTML/DOM. (Failure to escape in this way makes a `<script>` injection
|
||||
attack possible if your LaTeX source is untrusted.)
|
||||
|
||||
#### Rendering options
|
||||
|
||||
You can provide an object of options as the last argument to `katex.render` and `katex.renderToString`. Available options are:
|
||||
|
||||
- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`)
|
||||
- `throwOnError`: `boolean`. If `true`, KaTeX will throw a `ParseError` when it encounters an unsupported command. If `false`, KaTeX will render the unsupported command as text in the color given by `errorColor`. (default: `true`)
|
||||
- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color which unsupported commands are rendered in. (default: `#cc0000`)
|
||||
- `macros`: `object`. A collection of custom macros. Each macro is a property with a name like `\name` (written `"\\name"` in JavaScript) which maps to a string that describes the expansion of the macro. Single-character keys can also be included in which case the character will be redefined as the given macro (similar to TeX active characters).
|
||||
- `colorIsTextColor`: `boolean`. If `true`, `\color` will work like LaTeX's `\textcolor`, and take two arguments (e.g., `\color{blue}{hello}`), which restores the old behavior of KaTeX (pre-0.8.0). If `false` (the default), `\color` will work like LaTeX's `\color`, and take one argument (e.g., `\color{blue}hello`). In both cases, `\textcolor` works as in LaTeX (e.g., `\textcolor{blue}{hello}`).
|
||||
- `maxSize`: `number`. If non-zero, all user-specified sizes, e.g. in `\rule{500em}{500em}`, will be capped to `maxSize` ems. Otherwise, users can make elements and spaces arbitrarily large (the default behavior).
|
||||
### 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}\\in\\RR", element, {
|
||||
displayMode: true,
|
||||
macros: {
|
||||
"\\RR": "\\mathbb{R}"
|
||||
}
|
||||
katex.render("c = \\pm\\sqrt{a^2 + b^2}", element, {
|
||||
throwOnError: false
|
||||
});
|
||||
```
|
||||
|
||||
#### Automatic rendering of math on a page
|
||||
Call `katex.renderToString` to generate an HTML string of the rendered math,
|
||||
e.g., for server-side rendering. For example:
|
||||
|
||||
Math on the page can be automatically rendered using the auto-render extension. See [the Auto-render README](contrib/auto-render/README.md) for more information.
|
||||
|
||||
#### Font size and lengths
|
||||
|
||||
By default, KaTeX math is rendered in a 1.21× larger font than the surrounding
|
||||
context, which makes super- and subscripts easier to read. You can control
|
||||
this using CSS, for example:
|
||||
|
||||
```css
|
||||
.katex { font-size: 1.1em; }
|
||||
```js
|
||||
var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}", {
|
||||
throwOnError: false
|
||||
});
|
||||
// '<span class="katex">...</span>'
|
||||
```
|
||||
|
||||
KaTeX supports all TeX units, including absolute units like `cm` and `in`.
|
||||
Absolute units are currently scaled relative to the default TeX font size of
|
||||
10pt, so that `\kern1cm` produces the same results as `\kern2.845275em`.
|
||||
As a result, relative and absolute units are both uniformly scaled relative
|
||||
to LaTeX with a 10pt font; for example, the rectangle `\rule{1cm}{1em}` has
|
||||
the same aspect ratio in KaTeX as in LaTeX. However, because most browsers
|
||||
default to a larger font size, this typically means that a 1cm kern in KaTeX
|
||||
will appear larger than 1cm in browser units.
|
||||
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.
|
||||
|
||||
### Common Issues
|
||||
- Many Markdown preprocessors, such as the one that Jekyll and GitHub Pages use,
|
||||
have a "smart quotes" feature. This changes `'` to `’` which is an issue for
|
||||
math containing primes, e.g. `f'`. This can be worked around by defining a
|
||||
single character macro which changes them back, e.g. `{"’", "'"}`.
|
||||
- KaTeX follows LaTeX's rendering of `aligned` and `matrix` environments unlike
|
||||
MathJax. When displaying fractions one above another in these vertical
|
||||
layouts there may not be enough space between rows for people who are used to
|
||||
MathJax's rendering. The distance between rows can be adjusted by using
|
||||
`\\[0.1em]` instead of the standard line separator distance.
|
||||
- KaTeX does not support the `align` environment because LaTeX doesn't support
|
||||
`align` in math mode. The `aligned` environment offers the same functionality
|
||||
but in math mode, so use that instead or define a macro that maps `align` to
|
||||
`aligned`.
|
||||
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).
