skeleton-card.stories.ts

Overview

The skeleton-card.stories.ts file is a Storybook story definition file for the SkeletonCard React component. Storybook is a tool for developing and documenting UI components in isolation. This file configures how the SkeletonCard component is presented, documented, and demonstrated within the Storybook environment.

The primary purpose of this file is to provide metadata, controls, and example usage scenarios (stories) for the SkeletonCard component. It enhances component discoverability, testing, and documentation by setting up a structured and interactive showcase of the component's features and customization options.

Detailed Explanation

Imports

• Meta and StoryObj are imported from @storybook/react-webpack5 to define the story metadata and story objects with proper typing.

• SkeletonCard component is imported from the application source (@/components/skeleton-card).

Meta Object (meta)

The meta constant is an object that configures the default export of the Storybook story module. It satisfies the Meta type for the SkeletonCard component.

Properties:

• title: String - Defines the hierarchical path in Storybook UI where this component appears (Example/SkeletonCard).

• component: The actual React component (SkeletonCard) to be showcased.

• parameters: Object - Contains Storybook configuration parameters:

  • layout: 'centered' ensures the component preview is centered in the Canvas area.

  • docs.description.component: Markdown string describing the SkeletonCard component in detail, including usage, features, and import paths.

• tags: Array of strings - Currently contains 'autodocs' indicating that automatic documentation generation is enabled.

• argTypes: Defines controls for component props in Storybook:

  • className: Text control for passing additional CSS classes to customize styling.

• args: Default arguments for the component props, here className is initialized to an empty string.

Usage Example:

import { SkeletonCard } from '@/components/skeleton-card';

function MyComponent() {
  return <SkeletonCard className="w-64" />;
}

Story Definition: WithCustomWidth

This named export defines a single story variant for the SkeletonCard, demonstrating how to customize the width via the className prop.

Properties:

• args: Overrides default args by setting className to 'w-80' (Tailwind CSS width utility class).

• parameters.docs.description.story: Provides a Markdown description for this story variant in Storybook Docs.

• tags: Contains '!dev' indicating this story is not for development or internal use but for demonstration.

Usage Example:

<SkeletonCard className="w-80" />

Implementation Details and Algorithms

• This file itself contains no algorithms or complex logic; it primarily configures metadata and story definitions.

• The documentation embedded within the meta.parameters.docs.description.component explains that SkeletonCard:

  • Displays animated skeleton placeholders while content loads.

  • Shows three lines of skeletons with varying widths.

  • Supports styling customization via the className prop.

  • Is built on top of a lower-level Skeleton UI component for consistent appearance.

Interaction with Other Parts of the System

• Imports the SkeletonCard component from the core component library (@/components/skeleton-card).

• Consumed by the Storybook toolchain to:

  • Render the component in isolation.

  • Generate interactive documentation.

  • Provide design and development teams with a visual playground.

• Enables runtime manipulation of component props (via argTypes controls).

• Supports automated documentation generation with the autodocs tag.

Summary

skeleton-card.stories.ts is a Storybook configuration file that:

• Documents the SkeletonCard loading placeholder component.

• Provides a default centered layout for showcasing the component.

• Adds interactive controls for users to customize the CSS class applied.

• Includes a practical story variant demonstrating custom width usage.

• Enables automatic documentation generation for improved developer experience.

This file plays a key role in the UI development workflow by making the SkeletonCard visually testable, customizable, and well-documented in isolation from the rest of the application.
