Storybook Addon ThemePicker

This package provides a way to easily preview various themes applied to your emotion-based React components using Storybook.

Usage

As with all Storybook addons, first register the addon in your addons.js file:

import '@ebay/storybook-addon-themepicker/register';

Then, simply wrap your component using the WithThemes component:

import {WithThemes} from '@ebay/storybook-addon-themepicker';

storiesOf('MyComponent', module)
  .add('with themes', () => (
    <WithThemes themes={themeChoices}>
      <MyComponent />
    </WithThemes>
  ));

The themes parameter passed to WithThemes should be an array of objects, each containing a theme name and the theme itself:

const defaultTheme = {
  borderColor: '#333',
  backgroundColor: '#eee',
  textColor: '#333'
};

const darkTheme = {
  borderColor: '#777',
  backgroundColor: '#333',
  textColor: '#eee'
};

const themeChoices = [
  {
    name: 'Normal',
    theme: defaultTheme
  },
  {
    name: 'Dark Mode',
    theme: darkTheme
  }
];

Using TypeScript

The package exports the ThemeDescriptor type for use with TypeScript. The above declaration of themeChoices would change to look like this in a TypeScript-based project:

import {ThemeDescriptor} from '@ebay/storybook-addon-themepicker';

// Your theme type:
type Theme = {
  borderColor: string;
  backgroundColor: string;
  textColor: string;
};

// Your theme objects that implement your theme type:
export const defaultTheme: Theme = {
  borderColor: '#333',
  backgroundColor: '#eee',
  textColor: '#333'
};

export const darkTheme: Theme = {
  borderColor: '#777',
  backgroundColor: '#333',
  textColor: '#eee'
};

// ThemeDescriptor is parameterized by your theme type:
const themeChoices: Array<ThemeDescriptor<Theme>> = [
  {
    name: 'Normal',
    theme: defaultTheme
  },
  {
    name: 'Dark Mode',
    theme: darkTheme
  }
];
