# Progress

A React component in [Beamline](https://beamline.io/)'s [Feedback](https://beamline.io/components/feedback) category. Live demo: https://beamline.io/components/progress

How much of a known task is done, or a moving bar when the length is unknown, with an optional label and value.

## Use it for

- Known progress of a task: import, upload, onboarding completion.

## Not for

- Unknown duration ([spinner](https://beamline.io/components/spinner)). Usage against a limit ([usage-meter](https://beamline.io/components/usage-meter)).

## Anatomy

- root wrapper (Radix progress track inside)
- header (label, value)
- track
- fill

## Variants

- **tone**: accent, success, warning, danger
- **size**: sm, md

## States

- determinate (value)
- indeterminate (value null)
- complete (value = max)

## Keyboard

- Not focusable; exposes role progressbar with value.

## Motion

The fill eases to each new value over --pui-duration-standard; the indeterminate bar sweeps until a value arrives and stands still under reduced motion. When the value changes, the change itself stays in view for a moment (_shared/delta-ghost): what was lost sits as a pale ghost under the fill, holds about 0.7 s and drains toward the new end; what was gained arrives lit and cools over about 1.3 s. The ghost spans the real before and after, never an in-between value; a run of changes the same way extends one ghost. Reduced motion: the ghost is shown still for 1.1 s, then removed.

## Props

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `value` | `number \| null` | `0` | null when the length is unknown. |
| `max` | `number` | `100` |  |
| `label` | `ReactNode` | — | Shown above the bar and used as its accessible name. |
| `showValue` | `boolean` | — | Shows the percentage (or value/max with format). |
| `format` | `(value, max) => string` | — | Custom value text, e.g. '12 of 40 files'. |
| `tone` | `"accent" \| "success" \| "warning" \| "danger"` | `"accent"` |  |
| `size` | `"sm" \| "md"` | `"md"` |  |
| `classNames` | `ProgressClassNames` | — |  |
| `style / ref` | `CSSProperties / native Ref` | — | Root styles; ref targets native wrapper div. |

## More in Feedback

- [Alert](https://beamline.io/components/alert): A message that stays until it is dealt with: what happened, what to do, an action; danger and warning are announced; dismissing folds its height away.
- [Announcement bar](https://beamline.io/components/announcement-bar): A banner across the top for news and offers: messages take turns, a countdown ticks, and dismissing folds it away and can remember it.
- [Empty state](https://beamline.io/components/empty-state): What a place will hold and the first step to fill it, instead of a blank; a compact size for panels and filtered tables.
- [Notification centre](https://beamline.io/components/notification-center): Updates that wait to be read: a bell with the unread count opens All / Unread, new and earlier groups, and per item mark read or dismiss.
- [Skeleton](https://beamline.io/components/skeleton): Holds the shape of content while it loads, then crossfades into it, so nothing jumps.
- [Spinner](https://beamline.io/components/spinner): A ring that spins while work runs and closes into a drawn check or cross when it ends.
- [Usage meter](https://beamline.io/components/usage-meter): An allowance and what fills it: one bar split by source, the room left, a warning near the limit and the overflow in its own red well past a notch at the…
