Naming components and hierarchy

Watch a video tutorial on the Storybook channel

Storybook provides a powerful way to organize your stories, giving you the necessary tools to categorize, search, and filter your stories based on your organization's needs and preferences.

Structure and hierarchy

When organizing your Storybook, there are two methods of structuring your stories: implicit and explicit. The implicit method involves relying upon the physical location of your stories to position them in the sidebar, while the explicit method involves utilizing the title parameter to place the story.

Storybook sidebar hierarchy

Based on how you structure your Storybook, you can see that the story hierarchy is made up of various parts:

  • Category: The top-level grouping of stories and documentation pages generated by Storybook
  • Folder: A mid-level organizational unit that groups components and stories in the sidebar, representing a feature or section of your application
  • Component: A low-level organizational unit representing the component that the story is testing
  • Docs: The automatically generated documentation page for the component
  • Story: The individual story testing a specific component state

Naming stories

When creating your stories, you can explicitly use the title parameter to define the story's position in the sidebar. It can also be used to group related components together in an expandable interface to help with Storybook organization providing a more intuitive experience for your users. For example:

Yields this:

Stories hierarchy without paths

Grouping

It is also possible to group related components in an expandable interface to help with Storybook organization. To do so, use the / as a separator:

Yields this:

Stories hierarchy with paths

Roots

By default, the top-level grouping will be displayed as “root” in the Storybook UI (i.e., the uppercased, non-expandable items). If you need, you can configure Storybook and disable this behavior. Useful if you need to provide a streamlined experience for your users; nevertheless, if you have a large Storybook composed of multiple component stories, we recommend naming your components according to the file hierarchy.

Single-story hoisting

Single-story components (i.e., component stories without siblings) whose display name exactly matches the component's name (last part of title) are automatically hoisted up to replace their parent component in the UI. For example:

Stories hierarchy with single story hoisting

Because story exports are automatically "start cased" (myStory becomes "My Story"), your component name should match that. Alternatively, you can override the story name using myStory.storyName = '...' to match the component name.

Sorting stories

Out of the box, Storybook sorts stories based on the order in which they are imported. However, you can customize this pattern to suit your needs and provide a more intuitive experience by adding storySort to the options parameter in your preview.js file.

Asides from the unique story identifier, you can also use the title, name, and import path to sort your stories using the storySort function.

The storySort can also accept a configuration object.

FieldTypeDescriptionRequiredDefault ValueExample
methodStringTells Storybook in which order the stories are displayedNoStorybook configuration'alphabetical'
orderArrayThe stories to be shown, ordered by supplied nameNoEmpty Array []['Intro', 'Components']
includeNamesBooleanInclude story name in sort calculationNofalsetrue
localesStringThe locale required to be displayedNoSystem localeen-US

To sort your stories alphabetically, set method to 'alphabetical' and optionally set the locales string. To sort your stories using a custom list, use the order array; stories that don't match an item in the order list will appear after the items in the list.

The order array can accept a nested array to sort 2nd-level story kinds. For example:

Which would result in this story ordering:

  1. Intro and then Intro/* stories
  2. Pages story
  3. Pages/Home and Pages/Home/* stories
  4. Pages/Login and Pages/Login/* stories
  5. Pages/Admin and Pages/Admin/* stories
  6. Pages/* stories
  7. Components and Components/* stories
  8. All other stories

If you want specific categories to sort to the end of the list, you can insert a * into your order array to indicate where "all other stories" should go:

In this example, the WIP category would be displayed at the end of the list.

Note that the order option is independent of the method option; stories are sorted first by the order array and then by either the method: 'alphabetical' or the default configure() import order.
