|
||
|
||
## Global
|
||
If you include the `katex.js` directly, the `katex` object will be available as
|
||
a global variable.
|
||
|
||
```html
|
||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.css" integrity="sha384-b/NoaeRXkMxyKcrDw2KtVtYKkVg3dA0rTRgLoV7W2df3MzeR1eHLTi+l4//4fMwk" crossorigin="anonymous">
|
||
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.js" integrity="sha384-ern5NCRqs6nJ/a4Ik0nB9hnKVH5HwV2XRUYdQl09OB/vvd1Lmmqbg1Mh+mYUclXx" crossorigin="anonymous"></script>
|
||
```
|
||
|
||
KaTeX also provides minified versions:
|
||
|
||
```html
|
||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.min.css" integrity="sha384-dbVIfZGuN1Yq7/1Ocstc1lUEm+AT+/rCkibIcC/OmWo5f0EA48Vf8CytHzGrSwbQ" crossorigin="anonymous">
|
||
<script defer src="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.min.js" integrity="sha384-2BKqo+exmr9su6dir+qCw08N2ZKRucY4PrGQPPWU1A7FtlCGjmEGFqXCv5nyM5Ij" crossorigin="anonymous"></script>
|
||
```
|
||
|
||
The loading of scripts are [deferred using `defer` attribute](https://developer.mozilla.org/en/HTML/Element/script#Attributes)
|
||
to speed up page rendering. The `katex` object will be available after
|
||
[`DOMContentLoaded` event is fired on the `document`](https://developer.mozilla.org/ko/docs/Web/Reference/Events/DOMContentLoaded).
|
||
If you do not use `defer`, `katex` object will be available after corresponding
|
||
`script` tag.
|
||
|
||
If KaTeX is not used immediately or not critical, it is possible to load KaTeX
|
||
asynchronously. Add [`async` attribute](https://developer.mozilla.org/en/HTML/Element/script#Attributes)
|
||
to `script` and use [`rel="preload"` and `onload` attribute](https://github.com/filamentgroup/loadCSS)
|
||
on `link`.
|
||
|
||
You can prefetch KaTeX fonts to prevent FOUT or FOIT. Use [Font Loading API](https://developer.mozilla.org/en-US/docs/Web/API/CSS_Font_Loading_API)
|
||
or [Web Font Loader](https://github.com/typekit/webfontloader):
|
||
|
||
```html
|
||
<script>
|
||
window.WebFontConfig = {
|
||
custom: {
|
||
families: ['KaTeX_AMS', 'KaTeX_Caligraphic:n4,n7', 'KaTeX_Fraktur:n4,n7',
|
||
'KaTeX_Main:n4,n7,i4,i7', 'KaTeX_Math:i4,i7', 'KaTeX_Script',
|
||
'KaTeX_SansSerif:n4,n7,i4', 'KaTeX_Size1', 'KaTeX_Size2', 'KaTeX_Size3',
|
||
'KaTeX_Size4', 'KaTeX_Typewriter'],
|
||
},
|
||
};
|
||
</script>
|
||
<script defer src="https://cdn.jsdelivr.net/npm/webfontloader@1.6.28/webfontloader.js" integrity="sha256-4O4pS1SH31ZqrSO2A/2QJTVjTPqVe+jnYgOWUVr7EEc=" crossorigin="anonymous"></script>
|
||
```
|
||
|
||
You can also use [`rel="preload"`](https://developer.mozilla.org/en-US/docs/Web/HTML/Preloading_content).
|
||
Add `<link rel="preload" href=(path to WOFF2 font) as="font" type="font/woff2" crossorigin="anonymous">`
|
||
to `head`. Note that [only few browsers support it](https://caniuse.com/#feat=link-rel-preload)
|
||
and they all support WOFF2 so preloading WOFF2 fonts is enough.
|
||
|
||
See [Google Web Fundamentals - Web Font Optimization](https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/webfont-optimization)
|
||
for more detail.

## Module Loaders
|
||
### AMD
|
||
```html
|
||
<script type="text/javascript">
|
||
require([
|
||
"https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.js",
|
||
], katex => {
|
||
...
|
||
});
|
||
</script>
|
||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.css" integrity="sha384-b/NoaeRXkMxyKcrDw2KtVtYKkVg3dA0rTRgLoV7W2df3MzeR1eHLTi+l4//4fMwk" crossorigin="anonymous">
|
||
```
|
||
|
||
### ECMAScript module
|
||
```html
|
||
<script type="module" type="text/javascript">
|
||
import katex from 'https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.mjs';
|
||
...
|
||
</script>
|
||
<script nomodule defer src="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.js" integrity="sha384-ern5NCRqs6nJ/a4Ik0nB9hnKVH5HwV2XRUYdQl09OB/vvd1Lmmqbg1Mh+mYUclXx" crossorigin="anonymous"></script>
|
||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.10.1/dist/katex.css" integrity="sha384-b/NoaeRXkMxyKcrDw2KtVtYKkVg3dA0rTRgLoV7W2df3MzeR1eHLTi+l4//4fMwk" crossorigin="anonymous">
|
||
```
|
||
|
||
> Use [`nomodule` attribute](https://developer.mozilla.org/en/HTML/Element/script#Attributes)
|
||
to provide a fallback for older browsers that do not support ES modules.
|
||
|
||
## Download & Host Things Yourself
|
||
Download a [KaTeX release](https://github.com/KaTeX/KaTeX/releases),
|
||
copy `katex.js`, `katex.css`
|
||
(or `katex.min.js` and `katex.min.css` to use minified versions),
|
||
and the `fonts` directory, and include or import it like above.
|
||
|
||
You can also build from source. See [Building from Source](node.md#building-from-source)
|
||
for more details.
|
||
|
||
## Bundler
|
||
[Use Node.js package managers to install KaTeX and import it](node.md) in your
|
||
project. Then bundle using bundlers like [webpack](https://webpack.js.org/) or
|
||
[rollup.js](https://rollupjs.org/). Note that you have to bundle the stylesheet
|
||
(`katex.css`) or include it manually.
