hakimel/reveal.js 6.0.0

on GitHub

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.
