HELiX

HELiX

Lit 3.x web components for healthcare applications. WCAG 2.2 AAA self-certified on the P0 surface (44 components, 376 Supports / 109 Not Applicable / 0 Partial / 0 Fail across 11 cert criteria plus an hx-icon non-text-contrast supplemental verdict; reproducible via pnpm aaa:audit).

Get started

The fastest path is the scaffolder:

npx create-helix

It prompts for framework, components, and bundles — then writes a working project you can pnpm dev immediately. See create-helix CLI for flags, presets, and what each template ships.

Or step through manually:

• Install — npm packages + peer-dep setup
• Quick start — your first hx-button
• Component reference — live Storybook with every component
• Drupal integration — module install, behaviors, Twig
• Framework integration — React wrappers (@helixui/react), plus integration guides for Next.js, Vue, Angular, Svelte, Astro, and plain HTML

Latest release

@helixui/library@3.11.2 + @helixui/icons@1.1.0 — see CHANGELOG for the release date.

Recent patches: the published dist/css/ bundles no longer contain leaked JavaScript from components whose styles are split across several css tagged literals (hx-table, hx-grid, hx-structured-list, hx-toast, and the category bundles that include them), and hx-icon-button, hx-copy-button, and hx-color-picker no longer double-announce their label on NVDA. The @helixui/library/authoring subpath exposes mixinDelegatesAria and the light-DOM style utilities for consumer components.

Upgrading from 3.8.x? The 3.8.0 → 3.9.0 migration guide covers the back-compat notes for that step.

Accessibility

HELiX targets WCAG 2.2 AAA on its P0 surface. The cert is self-certified — see the VPAT 2.5 conformance report for the per-criterion ledger.
