Example presentation

Example presentation

# `joplin-plugin-revealjs-slides`


- Separate slides with `---`s (if you're using the rich text editor, press the "horizontal line" button).
- The rest of this example presentation will assume you're using the markdown editor.


This plugin uses [reveal.js]( internally. [Read about writing reveal.js presentations here](


## A note on markdown rendering

`joplin-plugin-revealjs-slides` uses Joplin's markdown renderer internally *not* `reveal.js`'s markdown renderer.

<!-- Read about fragments here: -->
<div class="fragment fade-up">

Thus, some of [reveal.js's markdown features are not supported](

<div class="fragment fade-up">

However, this also means that many of Joplin's built-in features are supported. (For example, slideshows can be customized with [userstyle.css](



[Note links can also be included](:/9aeb224225314a1b9d7ee977ffeb3078) (though note that they may not work perfectly!)

Slides can be linked to like this: [link to slide 3](#3).


# $\KaTeX$ is supported.

// highlight.js is supported (through Joplin's
// markdown renderer).
function foo() {


**Mermaid** is also supported

graph TD;


**Speaker notes** can be created using an
<aside class="notes">

A setting exists to show speaker notes (when available).

<aside class="notes">

# Animating code blocks

Code blocks with highlighted line numbers need to be specified in HTML. See [the upstream reveal.js documentation]( for details.

<pre><code data-trim data-line-numbers="1|3|4">
// This
// is
// a test
// of code blocks.

Keyboard shortcuts

  • Press f to enter fullscreen and esc to exit fullscreen.
  • Press p to print the slideshow.
  • Press q or navigate to the last slide to show the Exit button.
  • Press ? to see a list of additional shortcuts.

Custom theme

It's possible to customize the theme for a slideshow with CSS by adding a <style> block to the top of a note. To do this:

  1. Make sure that the markdown editor is active. In markdown mode, the toggle button near the top of the screen should look like this (the "markdown" side should be highlighted): screenshot: Toggle editor button labeled near the top right of the screen

  2. At the top of the note, add the following:

        :root > body {
     	   --r-main-color: white;
     	   --r-heading-color: white;
     	   --r-background-color: darkgray;
     	   --r-link-color: lightblue;
  3. Adjust the colors in the <style> block to customize the theme.

  4. Start the presentation.

Note: Other editable theme variables are listed here.


HTML: For a web browser

To export a presentation to an HTML directory, right-click on a note, select export, then select "PRESENTATION.HTML - Export presentation as HTML": screenshot

A file dialog will then appear. Use this dialog to select an output directory.

The slides plugin will create a presentation subfolder within that directory, then a subfolder for the current note's notebook, then a .presentation.html file for the current note. Opening that file in a web browser allows viewing the presentation outside of Joplin. Note that this file uses resources in other parts of the presentation/ directory, so publishing or sharing just the .presentation.html file is not sufficient.

Note: Exported presentations use a light theme by default. See the Custom theme section above for how to customize the presentation and export theme.


  • Avoid running a presentation with untrusted markdown input.
  • A keyboard shortcut can be associated with starting the slideshow. To do this, open Joplin's settings, click "Keyboard shortcuts", and search for "slideshow". Next, click in the "keyboard shortcut" column. screenshot showing "start slideshow" in the list of keyboard shortcuts.
  • Press ? while in presentation mode to see a list of slideshow shortcuts. screenshot: A list of shortcuts, including space: to next slide, shift+space: to previous slide, p: print.

Known issues

  • Starting a presentation while the rich text editor is open may clear your undo history! The plugin briefly switches to the markdown editor before running the presentation. This switch may cause issues.
  • Does not support HTML notes.
  • If the note viewer is hidden, the presentation dialog will not update.

Building the plugin

The plugin is built using Webpack, which creates the compiled code in /dist. A JPL archive will also be created at the root, which can use to distribute the plugin.

To build the plugin, simply run yarn run dist.

The project is setup to use TypeScript, although you can change the configuration to use plain JavaScript.

Updating the plugin framework

To update the plugin framework, run npm run update.

In general this command tries to do the right thing - in particular it's going to merge the changes in package.json and .gitignore instead of overwriting. It will also leave "/src" as well as untouched.

The file that may cause problem is "webpack.config.js" because it's going to be overwritten. For that reason, if you want to change it, consider creating a separate JavaScript file and include it in webpack.config.js. That way, when you update, you only have to restore the line that include your file.
