eleventy-plugin-embedded-demos
A plugin for eleventy that allows you to have embedded demos using HTML, CSS and JavaScript, as well as having the code from those demos displayed in the page.
Install
Available on npm.
npm install --save-dev eleventy-plugin-embedded-demos
Usage
Loading and configuring
In your Eleventy config file (probably .eleventy.js), load the plugin module and use .addPlugin to add it to Eleventy. Like this:
const demos = require("eleventy-plugin-embedded-demos");
module.exports = function (eleventyConfig) {
eleventyConfig.addPlugin(demos);
};REMEMBER: You’re only allowed one module.exports in your configuration file, so make sure you only copy the require and the .addPlugin lines above!
You can also pass an object to the .addPlugin call as the second parameter to configure the plugin. Like this:
const demos = require("eleventy-plugin-embedded-demos");
module.exports = function (eleventyConfig) {
eleventyConfig.addPlugin(demos, {
path: "./src/demos",
filenames: {
javascript: "script.js",
},
});
};Any options you pass will be used to override the equivalent defaults.
Demo layout
You'll need a layout for your demo files so that all the various parts of the demo can be included.
The plugin adds 2 shortcodes to enable this:
demoCss: inlines the CSS for that demo into the pagedemoJS: inlines the JS for that demo into the page
An example of a minimal Nunjucks layout for demo files would be this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>{{ title }}</title>
{% demoCss %}
</head>
<body>
<main id="demo-content" title="{{ title }}">
{{ content | safe }}
</main>
{% demoJS %}
</body>
</html>You'll then need to specify that your demo pages should use this layout, either in your template front-matter or in a directory data file
Creating a demo
To create a demo, create a folder within your demos folder (default: ./demos). This can also be nested if you want to group multiple demos.
The only required file for a demo is a page written in any template language supported by Eleventy. The plugin looks for index.* by default.
You can optionally have a CSS file (default name styles.css) and a JavaScript file (default name main.js).
You can overide the CSS and JavaScript file names for a particular demo in your main demo file front-matter, as keys under a filenames key. For example:
---
title: "Basic clip-path demo"
filenames:
javascript: "script.js"
---Embedding demos in pages
You can embed a demo in your page using the embeddedDemo shortcode and passing it the path within your demos folder that the plugin should look for the files in.
For example, if we had a demo that lived at ./demos/clip-path/basic, we'd call the shortcode in Nunjucks like this:
{% embeddedDemo "clip-path/basic" %}Configuration options
Below are all the options that can be passed to the plugin:
path
./demos
The path to your demos folder, relative to the root of your Eleventy project.
Note: This must be inside your Eleventy input directory

parsers
{
html: "html",

{
html: "index.*",
css: "styles.css",

}Defaults
All of the defaults are exposed on the defaults property of the module, so they can be used in your config if necessary.
