Stat Card

Preview

Rendered from the story the storybook (a11y) CI gate runs axe against — the preview can't show something that hasn't been verified.

Install

Two equivalent paths — the URL works in any shadcn-CLI setup; the alias works once you've registered @interlace in your components.json.

npx shadcn@latest add https://ds.interlace.tools/r/stat-card.json

npx shadcn@latest add @interlace/stat-card

Import

3 named exports — pull the parts you need.

import { MIN_VIEWPORT, StatCard, statCardVariants } from '@/components/ui/patterns/stat-card';

Anatomy

Extracted from the primitive's JSDoc header. The source is the only documentation that can't drift.

StatCard                         (article — data-min-viewport=320)
    ├─ <div>                       (header row — label + icon)
    │   ├─ Typography ui-sm        (label)
    │   └─ {icon}                  (lucide icon, optional)
    ├─ Typography h2               (value — tabular numerals)
    ├─ {delta}                     (optional — "+12.3% · 30d" — tone-tinted)
    └─ {footnote}                  (optional smaller meta — "since launch")

Variants

Closed prop unions enforced by class-variance-authority. See Storybook's Variants story for the rendered matrix.

• tone
  • defaultdefault
  • success
  • warning
  • danger

API reference

Parsed from the type declarations in the source — the same file the install writes into your tree, so this table can't drift from the component you get.

Skeleton

Pass loading and the component renders a shape-matched <Skeleton /> in its own place — same box, so nothing reflows when the data lands. Below is the same story with loading={true}.

<MIN_VIEWPORT loading={isPending} />

Accessibility

Every story for this component is rendered headlessly and checked with axe-core (wcag2aa, wcag22aa, best-practice, ACT) on every PR. That gate has no continue-on-error, so what ships has zero known violations.

What follows is what static analysis can see. Axe cannot press a key and never sees an overlay open, so the operable-without-a-mouse claim lives in Behavior instead, where the keyboard path is replayed step by step.

Focus + keyboard behaviour

Native element semantics — no interaction layer to get wrong.

Focus ring (WCAG 2.2 SC 2.4.13)

Not focusable — no focus indicator required.

Reduced motion

No animation to gate.

ARIA in the source

None — semantics come from the element or the Base UI primitive rather than hand-written ARIA.

Examples

4 more states from the same story file.

R-rule compliance

Every primitive in @interlace/ui models to the portable 26-rule floor enforced by the componentApi ESLint preset. The cells below pin exactly where each rule applies in this file.

/**
 * @interlace/ui — StatCard
 *
 * A single labeled metric — the building block of dashboards, scorecards,
 * and "key results" rows. Renders: label / value / optional delta / optional
 * icon. The `tone` variant pairs the delta accent with one of four semantic
 * colors (default / success / warning / danger).
 *
 * Numbers are rendered with `font-variant-numeric: tabular-nums` (inherited
 * from preflight when wrapped in a `[data-tabular-nums]` container or table)
 * — set `data-tabular-nums` on the StatCard root to opt in.
