HELiX Storybook 10.x Audit Report

Date: 2026-03-11 Branch: feature/audit-storybook-completeness Storybook Version: 10.2.8 Framework: @storybook/web-components-vite

Executive Summary

The HELiX Storybook setup is enterprise-grade with strong foundations. Of 73 component directories, 72 have stories (98.6% coverage). CEM integration, accessibility auditing, theme switching, and healthcare-contextualized examples are all in place. Key gaps exist in viewport/responsive testing, composition pattern stories, and interaction test coverage for secondary components.

1. Story Coverage

Status: EXCELLENT (98.6%)

Metric Value
Total component directories 73
Components with stories 72
Components without stories 1
Total story files 75 (3 components have 2 story files)
Story file coverage 98.6%

Missing Story: hx-icon-button

  • Directory: packages/hx-library/src/components/hx-icon-button/
  • Status: Directory contains only AUDIT.md - no component implementation, no stories
  • Issue: Component directory exists but is empty/incomplete (7 P1 issues, 6 P2 issues noted in AUDIT.md)

Multi-Story Components

Component Story Files
hx-menu hx-menu.stories.ts, hx-menu-item.stories.ts
hx-radio-group hx-radio-group.stories.ts, hx-radio.stories.ts
hx-side-nav hx-side-nav.stories.ts, hx-nav-item.stories.ts

2. Controls & ArgTypes

Status: EXCELLENT

All sampled story files define explicit argTypes with proper control types, categories, descriptions, and default values.

Best-in-class examples:

  • hx-text-input: 15+ argTypes with select, boolean, text, number controls
  • hx-button: 9 argTypes with select (6 variants, 3 sizes), boolean (disabled, loading)
  • hx-checkbox: Comprehensive state controls (checked, indeterminate, disabled, required)
  • hx-pagination: 8 argTypes covering all configuration options

Control patterns used consistently:

  • select for enums (variant, size, placement)
  • boolean for flags (disabled, loading, required, open)
  • text for strings (label, placeholder, value)
  • number for numeric values (distance, totalPages)
  • table.category grouping for organization
  • defaultValue and type.summary for documentation
  • matchers configured globally: color picker for *color* props, date picker for *Date* props
  • sort: 'requiredFirst' for discoverability

Minor gaps:

  • hx-data-table: Only 6 argTypes despite complex API (missing column config, row selection mode)
  • hx-form: Only 4 argTypes (method, action, novalidate, name) - could expose layout mode
  • hx-accordion: Only 1 argType (mode) - could expose disabled, heading level

3. Variant Coverage

Status: STRONG (A- overall)

Tier 1 - Complete variant coverage (all states demonstrated):

Component Variants Sizes States Kitchen Sink Grade
hx-button 6 (primary through outline) 3 (sm/md/lg) disabled, loading AllVariants, AllSizes, AllCombinations, AllStates A+
hx-card 3 (default/featured/compact) - 3 elevations AllVariants, AllElevations, AllCombinations A+
hx-text-input 7 types 3 (sm/md/lg) 7 states AllTypes, AllSizes, AllStates, ValidationStates A+
hx-dialog modal/non-modal - open/closed, custom header, footer DangerConfirmation, AlertDialog, FormInsideDialog A

Tier 2 - Good but incomplete:

Component What's Present What's Missing
hx-dropdown 3 trigger types, disabled, 6 placements Open state demo, keyboard nav story
hx-toast Default story visible Individual variant stories (success/warning/danger/info)
hx-alert Default visible Individual variant stories (info/success/warning/error)
hx-spinner Small, Medium sizes Large size, variant stories (primary/inverted)
hx-accordion Single-mode default Multi-mode expansion, nested accordion

Note: Many Tier 2 components likely have more stories beyond the first 100 lines sampled. A full file read is recommended to confirm.

4. Accessibility Addon

Status: COMPLETE

Configuration:

  • @storybook/addon-a11y v10.2.8 installed and configured
  • axe-core integration active with color contrast checks explicitly enabled
  • Accessibility panel available on every story automatically
  • WCAG 2.1 AA auditing available in the A11y tab

In-story accessibility testing (play functions):

  • ARIA role verification (role="button", role="dialog", etc.)
  • aria-label and aria-labelledby checks
  • tabindex verification
  • Keyboard navigation testing (Tab, Enter, Space, Escape)
  • Focus management and focus restoration
  • Screen reader compatibility patterns

Strength: Accessibility is deeply embedded in play functions, not just relying on the addon panel.

5. Interaction Tests (Play Functions)

Status: STRONG for core components, GAPS in secondary

Components with excellent play function coverage:

Component Play Functions Patterns Tested
hx-button 8-10 Click events, keyboard activation (Enter/Space), form submit, disabled state, focus ring
hx-card 6 Shadow DOM structure, click handler, keyboard Enter/Space, focus management
hx-text-input 8+ Type & verify, event verification (hx-input/hx-change), clear & retype, keyboard nav, FormData participation, disabled lock, focus management
hx-dialog 8 Closed state, modal open, non-modal, backdrop close, custom header ARIA, trigger button, event firing, form inside dialog

Components with minimal/no play functions:

Component Play Functions Gap
hx-dropdown 1 (basic open toggle) No keyboard nav (arrow keys, Escape), no selection events, no focus trap
hx-toast None visible No auto-dismiss timer test, no close button test
hx-alert None visible No dismiss interaction test
hx-accordion 1 (item count check) No expand/collapse interaction, no keyboard nav, no mode switching
hx-spinner None visible N/A (non-interactive)
hx-pagination Not visible Should have page navigation, keyboard tests

6. Docs Pages (CEM-Driven Autodocs)

Status: COMPLETE

CEM Integration:

  • setCustomElementsManifest() called in preview.ts with full CEM data
  • 87 components documented in custom-elements.json
  • Autodocs automatically populate API tables: properties, events, slots, CSS parts, CSS custom properties

CEM Statistics:

Aspect Coverage
Components with descriptions 86/87 (99%)
Properties documented 85/87 (98%)
Events documented 52/87 (60%)
Slots documented 78/87 (90%)
CSS Parts documented 81/87 (93%)
CSS Properties documented 81/87 (93%)

Gap: hx-date-picker lacks a component description. 35 components lack event documentation (some may be intentional if they don't emit events).

MDX Documentation Pages (8 files):

  • Introduction.mdx - Welcome page with animated hero
  • components/hx-card.mdx - Card guide with Drupal integration
  • components/hx-form.mdx - Form patterns, ElementInternals, Drupal Form API
  • components/hx-select.mdx - Select with healthcare use cases
  • tokens/Colors.mdx - Color token swatches
  • tokens/Typography.mdx - Font specimens and scales
  • tokens/Spacing.mdx - Spacing scale visualization
  • tokens/Shadows.mdx - Elevation levels
  • tokens/Borders.mdx - Border radius and width
  • drupal/BestPractices.mdx - CDN, Twig, behaviors, AJAX

CEM Analyzer MCP Server provides validation scoring and breaking change detection.

7. Dark Mode / Theming

Status: COMPLETE

Implementation:

  • @storybook/addon-themes v10.2.8 configured with withThemeByDataAttribute decorator
  • Two themes: light (default) and dark
  • Theme toggle available in Storybook toolbar
  • Activates via data-theme attribute on <html> element
  • @helixui/tokens/tokens.css provides :root[data-theme="dark"] overrides

Background Options:

  • Light (#ffffff), Grey (#f8f9fa), Dark (#212529)

In-story theming:

  • CSS custom property stories (e.g., ThemedDialog showing --hx-dialog-* overrides)
  • Design token cascade demonstrated (primitive -> semantic -> component)

8. Composition Patterns

Status: GOOD in component stories, MISSING as standalone patterns

Composition stories within component files:

Component Composition Stories
hx-button ButtonGroup, WithIcon, IconOnly, InAForm, InACard, PatientActions (7 stories)
hx-card CardGrid, CardWithBadge, CardWithAlert, CardWithForm, InAContainer, PatientSummaryCard, PatientDashboard (7 stories)
hx-text-input InAForm, WithOtherFields, InACard, PatientSearch, MedicalRecordNumber, PhoneNumber, SSNMasked (7 stories)
hx-dialog FormInsideDialog, DangerConfirmation, TriggerButton (3 stories)
hx-dropdown PatientActions healthcare use case (1 story)

What's missing:

  • No standalone "Patterns" or "Recipes" section in Storybook navigation
  • No dedicated composition stories for: form fields + validation flow, data table + pagination, navigation + side panel layout, toast notification + trigger
  • Composition patterns ARE documented in /apps/docs/ (Starlight) but NOT as interactive Storybook stories
  • No multi-component workflow stories (e.g., complete patient intake form, dashboard layout)

9. Mobile Responsive

Status: WEAK

Viewport addon: @storybook/addon-viewport is NOT explicitly configured in main.ts addons. Storybook's built-in viewport presets are available but not customized.

Components with viewport stories:

Component Story Viewport
hx-nav MobileView mobile1 preset
hx-top-nav MobileViewport mobile1 preset
hx-top-nav MobileToggle Manual resize instruction

What's missing:

  • Only 2 of 73 components have mobile viewport stories
  • No custom viewport presets for healthcare-specific devices (tablets, medical kiosks, bedside monitors)
  • No responsive behavior stories for: hx-grid, hx-data-table, hx-form, hx-dialog, hx-drawer, hx-split-panel
  • No tablet viewport stories
  • Grid/layout components should demonstrate breakpoint behavior

What's Complete

  • 72/73 components have Storybook stories (98.6%)
  • CEM integration with setCustomElementsManifest() for autodocs
  • @storybook/addon-a11y with axe-core for WCAG auditing
  • Dark/light theme switching via addon-themes
  • Comprehensive argTypes with proper control types on core components
  • Excellent play functions on hx-button, hx-card, hx-text-input, hx-dialog
  • Healthcare-contextualized examples throughout (patient workflows, clinical scenarios)
  • Design token documentation (5 MDX pages for colors, typography, spacing, shadows, borders)
  • Drupal integration documentation (BestPractices.mdx)
  • Custom Storybook UI theme with HELiX branding
  • Story sort order (Welcome -> Tokens -> Components)
  • Global padding decorator and theme switcher decorator

What's Missing

  • Viewport addon not configured; only 2 components have mobile stories
  • No standalone composition/pattern stories
  • Interaction tests sparse outside core 4 components
  • No RTL testing stories
  • No stress/performance stories
  • hx-icon-button entirely missing
  • Several secondary components lack full variant coverage in stories
  • 35 components missing event docs in CEM

What's Broken

  • Storybook build (npm run build for @helixui/storybook) fails - needs investigation

Recommendations (Priority Order)

  1. Fix Storybook build - blocking deployment of Storybook docs
  2. Add @storybook/addon-viewport with healthcare device presets and add responsive stories to layout components (grid, data-table, form, dialog)
  3. Create composition pattern stories - move patterns from Starlight docs into interactive Storybook stories
  4. Add play functions to interactive secondary components (dropdown keyboard nav, toast auto-dismiss, alert dismiss, accordion expand/collapse)
  5. Complete hx-icon-button implementation or remove the empty directory
  6. Add missing variant stories for toast, alert, accordion, spinner
  7. Audit CEM event documentation - determine which of the 35 components genuinely emit no events vs. missing docs
  8. Add RTL testing stories for healthcare internationalization support
