This Addon lets you switch the data-theme attribute in your Storybook, by selecting a defined theme from a toolbar dropdown and adding the selected theme to the data-theme attribute of storybooks iframe html element.

This comes in handy if you want to test your components with different themes.

Compatibility

This addon is compatible with storybook version ^7.0.x.

Installation

npm install storybook-addon-data-theme-switcher --save-dev

Getting Started

Then activate the addon by adding it to the storybook main.js file (located in the Storybook config directory):

module.exports = {
  addons: [
    // other addons here
    "storybook-addon-data-theme-switcher",
  ],
};

Configuration

The addon makes use of storybooks globalTypes to define and load the themes.

To define a selection of themes, you can add the following to your global storybook configuration file preview.js:

export const globalTypes = {
  dataThemes: {
    defaultValue: {
      list: [
        { name: "Rainforest", dataTheme: "rainforest", color: "#00755e" },
        { name: "Candy", dataTheme: "candy", color: "#ffb7d5" },
        { name: "Rose", dataTheme: "rose", color: "#ff007f" },
      ],
    },
  },
};

To set a default data-theme value, which will be used in the initial load of the storybook, you can add the following to your preview.js file:

export const globalTypes = {
  dataTheme: {
    defaultValue: "rainforest",
  },
};

Note: Make sure to match the dataTheme default value with one of the defined themes in the list array.
