reveal-splash v1.0.2

reveal-splash Plugin

Effortlessly elevate your Reveal.js presentations with a sleek, customizable splash screen.

Motivation

When using Reveal.js to write extensive lectures, I encountered long load times as the presentations grew larger. To improve the user experience, I wanted a splash screen that would display while the content loaded. The reveal-splash plugin was created to address this need, offering flexibility and customization to suit any presentation style.

Installation

Option 1: Direct HTML Include

Include the plugin directly in your HTML file:

<script type="module">
    import Splash from './path/to/reveal-splash.esm.js';
</script>

Option 2: Install via npm

If you’re using a Node.js environment, install the plugin via npm:

npm install reveal-splash

Then, import the plugin in your JavaScript file:

import Splash from 'reveal-splash-plugin';

Basic Usage

To use the reveal-splash plugin, include it in the Reveal.initialize function and configure it according to your needs:

Reveal.initialize({
    plugins: [Splash],
    splash: {
        splashImage: false,
        backgroundColor: "#33aa33",
        text: "Loading presentation, please wait...",
        fontOptions: {
            fontFamily: "Verdana, sans-serif",
            fontSize: "20px",
            color: "#ffffff",
        },
        minimumDisplay: 2
    }
});

Note: If I'm not mistaken, reveal.js will load each plugin asynchronously, so you may see other plugins at work before this kicks in.

Configuration

The plugin offers several configuration options to help you create the perfect splash screen:

Example Configuration Snippet

Here’s a snippet showing how to configure the splash screen with a custom image, HTML text, and styling:

Reveal.initialize({
    plugins: [Splash],
    splash: {
        splashImage: 'img/splash-logo.png',
        backgroundColor: '#444',
        text: '<p>Loading <code>reveal-splash</code> demo...</p>',
        fontOptions: { color: "#ffffff", fontSize: "36px" },
        minimumDisplay: 5
    }
});

Advanced Customization

You can further enhance the splash screen by using custom HTML and CSS animations. Here’s an example of how to create a neon glow effect for the splash screen text:

In your splash configuration:

...
text: '<p class="neon-glow">Make a Splash with reveal-splash!</p>',
...

In the head of your presentation, or in an imported css file:

.neon-glow {
    color: #00FFFF;
    text-shadow: 
        0 0 5px #00FFFF,
        0 0 10px #00FFFF,
        0 0 20px #00FFFF,
        0 0 30px #00FFFF,
        0 0 40px #00FFFF,
        0 0 50px #00FFFF,
        0 0 75px #00FFFF;
    animation: pulse 1.5s infinite alternate, flicker 2s infinite;
}
