Install

Plugin

Using composer:

composer global require getkirby/cli
composer require bnomei/kirby3-storybook --dev

You need to install the CLI with composer since this plugin depends on the CLI to be available either globally or locally.

Storybook

Please refer to the official docs on how to install Storybook if in doubt.

npm install storybook --sav-dev

TIP: I used storybook@^7.0.0-beta.12 for my tests.

npx storybook init --type vue3

TIP: I used vue3 for my tests, but you can stick to vue if you want to keep it consistent to other Kirby components.

Usage

Creating stories

The plugin can load data for your Snippet/Template files. You can use three different ways for Snippets and two for Templates. Check out the tests in this repository to see some examples.

Snippet stories

Let's assume a snippet named example.php in either site/snippets or registered via a plugin extension. Add any of these files into the same folder as the snippet.

example.stories.yml containing an array with a key-value pair for each PHP variable you need.
example.stories.json containing a KQL Query you want to be extracted into the snippet.
or add the extract(storybook($YOUR_DATA_ARRAY), EXTR_SKIP); call to the head of your snippet.

Template stories

Let's assume a template named blog.php in either site/templates or registered via a plugin extension. Add any of these files into the same folder as the template.

blog.stories.yml containing either an id key with the id of a page to load as value or an array called virtual with all data needed for a Page::factory() call.
blog.stories.json containing a KQL Query you want to be extracted into the template.

Storybook and the plugins file watcher

You need to run two tasks. First start Storybook.

npm run storybook

TIP: Make sure you can run storybook after installation at least once without errors. Then remove the demo files or copy them to a different location in case you need them for reference (like I usually do).

In a different shell run the file watcher.

kirby storybook:watch

The file watcher provided by this plugin needs the Kirby CLI and has various options for interval, displaying errors, running only once and a file pattern match. See help for details.

Some examples:

kirby storybook:watch --help
kirby storybook:watch --errors --once
kirby storybook:watch --interval 5000
kirby storybook:watch --pattern article
kirby storybook:watch --pattern '/.*blocks\/.*/'

Generated Files

The plugin will use the file watcher to monitor your Snippet/Template files and their story config files (aka *.stories.yml|json). If any of these files changes it will generate or overwrite the corresponding files in your Storybook stories folder. Creating subfolders as needed to match Kirbys extension registry (like snippets/blocks). It will NOT remove any files. There are three files created for each story.

Example.html contains the rendered HTML and will be overwritten on changes to the source files.
Example.stories.js defines details about your story for Storybook, like title or variants. It will only be created if missing. You can edit it as you like.
Example.vue standard Vue SFC. It references to the HTML file. This file allows you to add custom js/css or when the source is finalized remove the reference, copy the HTML into the vue-file and add support for variants etc.

Adding your CSS and JS assets

You could add the reference your a single css file manually with <style src="./../../app.css"></style> and import all your scripts to each vue SFC. But my suggested method out of 6 would be to import your assets in the ./storybook/preview.js and/or .storybook/main.js that storybook created. See example below:

./storybook/preview.js

+ import './../assets/css/app.css'
+ import "./../assets/js/alpine.min"

export const parameters = {
  actions: { argTypesRegex: "^on[A-Z].*" },
  controls: {
    matchers: {
      color: /(background|color)$/i,
      date: /Date$/,
    },
  },
}

./storybook/main.js

  ...
  "docs": {
    "docsPage": true
  },
+  "previewHead": (head) => (`
+    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@splidejs/splide@4.1.4/dist/css/splide.min.css" />
+    <script src="https://cdn.jsdelivr.net/npm/@splidejs/splide@4.1.4/dist/js/splide.min.js"></script>
+    ${head}
+  `),
