Progress

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/progress.json

npx shadcn@latest add @interlace/progress

Import

8 named exports — pull the parts you need.

import { MIN_VIEWPORT, Progress, ProgressIndicator, ProgressLabel, ProgressTrack, ProgressValue, progressIndicatorVariants, progressTrackVariants } from '@/components/ui/progress';

Anatomy

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

<Progress value={62}>                  ← BaseProgress.Root, data-min-viewport
    <ProgressLabel>Uploading</ProgressLabel>
    <ProgressValue />                    ← "62%"
    <ProgressTrack size="md">            ← rail
      <ProgressIndicator tone="default" /> ← filled portion
    </ProgressTrack>
  </Progress>

Variants

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

  • sm
  • mddefault

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.

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

Owned by @base-ui/react/progress — focus trapping, dismissal and typeahead come from the headless primitive, not from us.

Focus ring (WCAG 2.2 SC 2.4.13)

Not focusable — no focus indicator required.

Reduced motion

Animation is gated on prefers-reduced-motion.

ARIA in the source

• role="progressbar"

Examples

3 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 — Progress
 *
 * Determinate progress indicator. Wraps the Base UI `Progress` compound — Root,
 * Track, Indicator, Label, Value — and re-exports DS-styled parts that consume
 * theme tokens (no raw px, no hex). The Track defines the rail height (`size`);
 * the Indicator carries the filled tone (`tone`). Width animation is
 * disabled when `prefers-reduced-motion: reduce` is set — per the MOTION
 * philosophy, a CSS `transition-[width]` would otherwise animate from 0 → value
 * on every render, including for users who opted out.
