The Viewport toolbar item allows you to adjust the dimensions of the iframe your story is rendered in. It makes it easy to develop responsive UIs.

Configuration

Out of the box, the Viewport addon offers you a standard set of viewports that you can use. If you want to change the default set of viewports, you can set the global parameters.viewport parameter in your .storybook/preview.js:

The viewport global can take an object with the following keys:

| Field | Type | Description | Default Value | | ---------------------- | ------- | --------------------------------------------------------- | -------------- | | defaultViewport | String | Sets the default viewport | 'responsive' | | defaultOrientation | String | Sets the default orientation (e.g. portrait or landscape) | 'portrait' | | disable | Boolean | Disables the viewport | N/A | | viewports | Object | The configuration objects for the viewport | {} |

The viewports object needs the following keys:

| Field | Type | Description | Example values | | ---------- | ------ | ----------------------------------------------------- | ----------------------- | | name | String | Name for the viewport | 'Responsive' | | styles | Object | Sets Inline styles to be applied to the story | { width:0, height:0 } | | type | String | Type of the device (e.g., desktop, mobile, or tablet) | desktop |

The generic devices are enabled by default as they are the most common for testing responsive UIs. You don't need to include them in your configuration if you want to use them. For the implementation details, see the source code for the Viewport addon.

Add new devices

If you have either a specific viewport or a list of viewports that you need to use, you can modify your .storybook/preview.js file and include them:

Code Snippets

const customViewports = {
  kindleFire2: {
    name: 'Kindle Fire 2',
    styles: {
      width: '600px',
      height: '963px',
    },
  },
  kindleFireHD: {
    name: 'Kindle Fire HD',
    styles: {
      width: '533px',
      height: '801px',
    },
  },
};

Make the following changes to use them in your Storybook:

Once you start Storybook, you'll see your new viewports and devices.

You can add these two to another list of viewports if needed.

For instance, if you want to use these two with the minimal set of viewports, you can do it like so:

It would be great if you could report an issue on Github if you see that message.

Both viewports (Kindle Fire 2 and Kindle Fire HD) will feature in the list of devices by merging them into the MINIMAL_VIEWPORTS.

Configuring per component or story

In some cases, it's not practical for you to use a specific visual viewport on a global scale, and you need to adjust it to an individual story.

Update your story through parameters to include your viewports at a component level or for a specific story:

Previous viewport: alt + shift + v
Next viewport: alt + v
Reset viewport: alt + control + v

API

Parameters

This addon contributes the following parameters to Storybook, under the viewport namespace:

`defaultOrientation`

Type: 'portrait' | 'landscape'

Default: 'portrait'

Specifies the default orientation used when viewing a story.

`defaultViewport`

Type: string

Specifies the default viewport used when viewing a story. Must match a key in the viewports object.

`disable`

Type: boolean

Disable this addon's behavior. If you wish to disable this addon for the entire Storybook, you should do so when registering addon-essentials. See the essential addon's docs for more information.

This parameter is most useful to allow overriding at more specific levels. For example, if this parameter is set to true at the project level, it could then be re-enabled by setting it to false at the meta (component) or story level.

`viewports`

Type:

{
  [key: string]: {
    name: string,
    styles: { height: string, width: string },
    type: 'desktop' | 'mobile' | 'tablet',
  },
};

Specify the available viewports. The key is used to reference the viewport and the value is an object to define it. See usage example, above. The width and height values must include the unit, e.g. '320px'.

Exports

This addon contributes the following exports to Storybook:

import { INITIAL_VIEWPORTS, MINIMAL_VIEWPORTS } from '@storybook/addon-viewport';
