Math plugins (MathJax/KaTeX) for reveal.js.
Download and install the package in your project:
npm install --save reveal.js-math
Add the plugin to your presentation as below:
<script src="node_modules/reveal.js-math/dist/math.umd.js"></script>
<script>
Reveal.initialize({
plugins: [ RevealMath.<Variant> ]
});
</script>
or if you're using ES modules:
<script type="module">
import RevealMath from "./node_modules/reveal.js-math/dist/math.esm.js";
Reveal.initialize({
plugins: [ RevealMath.<Variant> ]
});
</script>
where <Variant>
is one of MathJax2
, MathJax3
, KaTeX
.
You can configure math by providing a reveal.js initialization object for your variant. These object have different names to allow easy switching between variants
Adjust options through the mathjax2
configuration object. Below is how the plugin is configured by default.
If you don't intend to change these values you do not need to include the mathjax2
config option at all.
Reveal.initialize({
mathjax2: {
mathjax: 'https://cdn.jsdelivr.net/npm/mathjax@2/MathJax.js',
config: 'TeX-AMS_HTML-full',
// pass other options into `MathJax.Hub.Config()`
tex2jax: {
inlineMath: [ [ '$', '$' ], [ '\\(', '\\)' ] ],
skipTags: [ 'script', 'noscript', 'style', 'textarea', 'pre' ]
}
},
plugins: [ RevealMath.MathJax2 ]
});
Note that the latest MathJax 2 is loaded from a remote server. To use a fixed version set mathjax
to, for example, https://cdn.jsdelivr.net/npm/[email protected]/MathJax.js.
If you want to use MathJax offline you'll need to download a copy of the library (e.g. with npm) and adjust mathjax
accordingly.
Adjust options through the mathjax3
configuration object. Below is how the plugin is configured by default.
If you don't intend to change these values you do not need to include the mathjax3
config option at all.
Reveal.initialize({
mathjax3: {
mathjax: 'https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js',
tex: {
inlineMath: [ [ '$', '$' ], [ '\\(', '\\)' ] ]
},
options: {
skipHtmlTags: [ 'script', 'noscript', 'style', 'textarea', 'pre' ]
},
},
plugins: [ RevealMath.MathJax3 ]
});
Note that the latest MathJax 3 is loaded from a remote server. To use a fixed version set mathjax
to, for example, https://cdn.jsdelivr.net/npm/[email protected]/tex-mml-chtml.js. Additionally, the config is now part of of the url, by default tex-mml-chtml
is loaded which recognizes mathematics in both TeX and MathML notation, and generates output using HTML with CSS (the CommonHTML output format). This is one of the most general configs, but it is also one of the largest, so you might want to consider a smaller one that is more tailored to your needs, e.g. tex-svg
.
If you want to use MathJax offline you'll need to download a copy of the library (e.g. with npm) and adjust mathjax
accordingly.
Adjust options through the katex
configuration object. Below is how the plugin is configured by default.
If you don't intend to change these values you do not need to include the katex
config option at all.
Reveal.initialize({
katex: {
version: 'latest',
delimiters: [
{left: '$', right: '$', display: false},
{left: '$$', right: '$$', display: true},
{left: '\\(', right: '\\)', display: false},
{left: '\\[', right: '\\]', display: true}
],
ignoredTags: ['script', 'noscript', 'style', 'textarea', 'pre']
},
plugins: [ RevealMath.KaTeX ]
});
Note that by default the latest KaTeX is loaded from a remote server (https://cdn.jsdelivr.net/npm/katex). To use a fixed version set version
to, for example, 0.13.18
.
If you want to use KaTeX offline you'll need to download a copy of the library (e.g. with npm) and use the local
configuration option (the version
option will then be ignored), for example:
Reveal.initialize({
katex: {
local: 'node_modules/katex',
},
plugins: [ RevealMath.KaTeX]
});
