New Package: @​revealjs/react

reveal.js now has an official React wrapper! The @revealjs/react package lets you build presentations using React components—<Deck>, <Slide>, <Stack>, <Fragment>, and <Code>. Learn more over at revealjs.com/react.

import { Deck, Slide, Fragment } from '@​revealjs/react';

<Deck>
  <Slide>
    <h1>Hello World</h1>
    <Fragment asChild>
      <h2>Appears on click</h2>
    </Fragment>
  </Slide>
</Deck>

Try it out by pulling reveal.js master and running npm run react:demo.

Breaking Changes

See the full upgrade guide for step-by-step instructions. The short version:

• Plugin paths have moved —if your presentation HTML loads plugins directly from the file system or via CDN, update your paths from plugin/<name>/plugin.js to dist/plugin/<name>.js (e.g. plugin/notes/notes.js → dist/plugin/notes.js, plugin/highlight/monokai.css → dist/plugin/highlight/monokai.css)
• ES module paths renamed — .esm.js files are now .mjs (e.g. dist/reveal.esm.js → dist/reveal.mjs). If you import via bare module specifiers this doesn't affect you.
• CSS paths changed — if you install via npm, the dist/ prefix has been dropped from the public package API (e.g. reveal.js/dist/reveal.css → reveal.js/reveal.css).
• TypeScript — reveal.js now ships with types included. If you were previously using @types/reveal.js you can remove it and migrate. Note that the type names are slightly different, more info in the upgrade guide.

New Feature: Lightbox

Any element in your presentation can now be turned into an image/video lightbox trigger. Clicking reveals a full-size lightbox overlay where users can view your image or video. This is great for things like clickable thumbnails in a gallery.

<!-- Click to show "A.png" in an overlay -->
<img src="A.png" data-preview-image>

<!-- Click show "B.png" in an overlay -->
<img src="A.png" data-preview-image="B.png">

<!-- Click to show "C.mp4" in an overlay and scale it to "cover" -->
<img src="A.png" data-preview-video="C.mp4" data-preview-fit="cover">

<!-- Works with any element type -->
<button data-preview-video="C.mp4">Play video</button>

Scroll view

reveal.js 5.0 comes with a groundbreaking new feature; scroll view! (#​3482)

Slide decks are a great format for giving presentations, but scrollable web pages are easier for viewers to read on their own.

The scroll view gives you the best of both worlds—without any extra effort. Present in the format best suited for presenting, share in the format best suited for consumption.

Here's what it looks in action:

reveal-scroll-view.mp4

Want to try it out yourself? Check out the announcement deck I put together for slides.com 👉 https://slides.com/news/scroll-mode/scroll

How to use it

The scroll view is enabled by initializing reveal.js with view: "scroll" or by appending ?view=scroll to a deck URL.

Reveal.initialize({ view: 'scroll' });

It's possible to fine tune this view through multiple new config options. Full documentation available at https://revealjs.com/scroll-view.

Breaking change

The scroll view is automatically enabled for viewports below 435px wide. This is done because I believe the scroll view to be a superior way to browse any deck on a mobile device. If you want to revert this behavior and always paginate between slides, see scrollActivationWidth:

Reveal.initialize({ scrollActivationWidth: null })

Changes

• The PDF print view can now be activated via config Reveal.initialize({ view: 'print' }) (@​hakimel in #​3482)
• The new URL query for activating the print view is ?view=print. It used to be ?print-pdf, which is still supported for backwards compatibility. (@​hakimel in #​3482)

Fixes

• Notes from data-notes were not working on the slide-level (@​skyboyer in #​3477)
• Add 'wheel' event listener, remove deprecated mousewheel & 'DOMMouseScroll` (@​quochuy in #​3489)
