Storybook Viewport Addon

Storybook Viewport Addon allows your stories to be displayed in different sizes and layouts in Storybook. This helps build responsive components inside of Storybook.

Framework Support

Screenshot

Installation

Install the following npm module:

npm i --save-dev @storybook/addon-viewport

or with yarn:

yarn add -D @storybook/addon-viewport

within .storybook/main.js:

module.exports = {
  addons: ['@storybook/addon-viewport/register'],
};

You should now be able to see the viewport addon icon in the the toolbar at the top of the screen.

Configuration

The viewport addon is configured by story parameters with the viewport key. To configure globally, import addParameters from your app layer in your preview.js file.

import { addParameters } from '@storybook/react';
 
addParameters({
  viewport: {
    viewports: newViewports, // newViewports would be an ViewportMap. (see below for examples)
    defaultViewport: 'someDefault',
  },
});

Options can take a object with the following keys:

defaultViewport : String

Setting this property to, let say iphone6, will make iPhone 6 the default device/viewport for all stories. Default is 'responsive' which fills 100% of the preview area.

viewports : Object

A key-value pair of viewport's key and properties (see Viewport definition below) for all viewports to be displayed. Default is MINIMAL_VIEWPORTS

Viewport Model

{
  /**
   * name to display in the dropdown
   * @type {String} 
   */
  name: 'Responsive',
 
  /**
   * Inline styles to be applied to the story (iframe).
   * styles is an object whose key is the camelCased version of the style name, and whose
   * value is the style’s value, usually a string
   * @type {Object} 
   */
  styles: {
    width: '100%',
    height: '100%',
  },
 
  /**
   * type of the device (e.g. desktop, mobile, or tablet)
   * @type {String} 
   */
  type: 'desktop',
}

Configuring per component or story

Parameters can be configured for a whole set of stories or a single story via the standard parameter API:

 
export default {
  title: 'Stories',
  parameters: {
    viewport: { defaultViewport: 'iphone6' },
  };
};
 
export const myStory = () => <div />;
myStory.story = {
  parameters: {
    viewport: { defaultViewport: 'iphonex' },
  },
};

Examples

Use Detailed Set of Devices

The default viewports being used is MINIMAL_VIEWPORTS. If you'd like to use a more granular list of devices, you can use INITIAL_VIEWPORTS like so in your .storybook/preview.js file.

import { addParameters } from '@storybook/react';
import { INITIAL_VIEWPORTS } from '@storybook/addon-viewport';
 
addParameters({
  viewport: {
    viewports: INITIAL_VIEWPORTS,
  },
});

Use Custom Set of Devices

This will replace all previous devices with Kindle Fire 2 and Kindle Fire HD by calling addParameters with the two devices as viewports in .storybook/preview.js file.

import { addParameters } from '@storybook/react';
 
const customViewports = {
  kindleFire2: {
    name: 'Kindle Fire 2',
    styles: {
      width: '600px',
      height: '963px',
    },
  },
  kindleFireHD: {
    name: 'Kindle Fire HD',
    styles: {
      width: '533px',
      height: '801px',
    },
  },
};
 
addParameters({
  viewport: { viewports: customViewports },
});

Add New Device

This will add both Kindle Fire 2 and Kindle Fire HD to the list of devices. This is achieved by making use of the exported INITIAL_VIEWPORTS or MINIMAL_VIEWPORTS property, by merging it with the new viewports and pass the result as viewports to configureViewport function

import { addParameters } from '@storybook/react';
import {
  INITIAL_VIEWPORTS,
  // or MINIMAL_VIEWPORTS,
} from '@storybook/addon-viewport';
 
const customViewports = {
  kindleFire2: {
    name: 'Kindle Fire 2',
    styles: {
      width: '600px',
      height: '963px',
    },
  },
  kindleFireHD: {
    name: 'Kindle Fire HD',
    styles: {
      width: '533px',
      height: '801px',
    },
  },
};
 
addParameters({
  viewport: {
    viewports: {
      ...INITIAL_VIEWPORTS,
      // or ...MINIMAL_VIEWPORTS,
      ...customViewports,
    },
  },
});
