Drupal Storybook Addon

A library for best-practice Drupal integration addons in Storybook:

  • Easy-to-use Drupal integration
  • Simple drop-down menu
  • URL-linkable state for sharing


Configure your Drupal site

๐ŸŒณ Install the Drupal module

Install and enable the Drupal module:

composer require drupal/cl_server;
drush pm:enable --yes cl_server;

๐ŸŒด Add Storybook to your Drupal repo

From the root of your repo:

yarn global add sb@latest;
sb init --builder webpack5 --type server
# If you have a reason to use Webpack4 use the following instead:
# sb init --type server
yarn add -D @lullabot/storybook-drupal-addon

๐ŸŒต Configure Storybook

First enable the addon. Add it to the addons in the .storybook/main.js.

// .storybook/main.js
module.exports = {
  // ...
  addons: [
    // ...
  // ...

Then, configure the supportedDrupalThemes and drupalTheme parameters in .storybook/preview.js.

supportedDrupalThemes is an object where the keys are the machine name of the Drupal themes and the values are the plain text name of that Drupal theme you want to use. This is what will appear in the dropdown in the toolbar.

// .storybook/preview.js
export const parameters = {
  // ...
  server: {
    // Replace this with your Drupal site URL, or an environment variable.
    url: 'http://local.contrib.com',
  drupalTheme: 'umami',
  supportedDrupalThemes: {
    umami: { title: 'Umami' },
    bartik: { title: 'Bartik' },
    claro: { title: 'Claro' },
    seven: { title: 'Seven' },
  // ...

Start Storybook

Start the development server Storybook server:

yarn storybook

Storybook addon authors

As an addon author, you can use this library by adding it as a dependency and adding the following to your /preset.js file:

function config(entry = []) {
  return [
    require.resolve('@lullabot/storybook-drupal-addon/preview'), // <-- library's preview preset
    require.resolve('./dist/esm/preset/preview'), // <-- your addon's preview preset (if present)

function managerEntries(entry = []) {
  return [
    require.resolve('./dist/esm/preset/manager'), // <-- your addon's manager (if present)

module.exports = { config, managerEntries };

The currently selected theme is available in the drupalTheme global, so you can access it using the following snippet:

import { useGlobals } from '@storybook/client-api';

const myDecorator = (story, context) => {
  const [{ drupalTheme }] = useGlobals();
  // Do something with the Drupal theme.
