Progress

A horizontal bar that shows the completion of a task.

Progress is an open-source component from suiss/ui for React, React Native, SwiftUI and Jetpack Compose. The @esuiss/ui CLI copies its source into your project, so you own the code.

import { Progress } from "@/components/ui/progress"

export default function ProgressDemo() {
  return (
    <div className="w-80">
      <Progress value={60} aria-label="Upload progress" />
    </div>
  )
}

Progress wraps the progress primitive of the chosen base. Progress is the root and always renders a ProgressTrack containing a ProgressIndicator after its children. Add a ProgressLabel to name the bar and a ProgressValue to show the formatted value; they sit on one row above the track.

Use Progress for determinate or indeterminate task progress.

Installation

CLI

$ pnpm dlx shadcn@latest add @esuiss/progress

Works in any project with a components.json. See Installation for the one-line registry setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add progress

Manual

Install the dependencies and add the cn helper:

$ pnpm add @base-ui/react

Copy the source into components/ui/progress.tsx:

Update the import paths to match your project.

Usage

import { Progress, ProgressTrack, ProgressIndicator, ProgressLabel, ProgressValue }

<div

Pass value as a number between min and max (by default 0 and 100). Set value={null} for an indeterminate state when the amount of work is unknown.

The track and indicator are rendered for you, so ProgressTrack and ProgressIndicator are not needed inside Progress children. ProgressValue shows the formatted value, a percentage by default.

Examples

With label

A bar with a label and its current value shown above the track.

Complete

A labelled bar at 100.

Indeterminate

A labelled bar with value={null} for work of unknown length.

API Reference

Anatomy3 parts

<ProgressLabel />

<ProgressValue />

Progress

The root that holds the value and renders the track and indicator.

Also accepts the props of the primitive part it wraps.

ProgressTrack

The full-width rail behind the indicator.

Also accepts the props of the primitive part it wraps.

ProgressIndicator

The filled portion of the track that reflects the value.

Also accepts the props of the primitive part it wraps.

ProgressLabel

Text that names the progress bar.

Also accepts the props of the primitive part it wraps.

ProgressValue

The formatted current value, aligned to the end of the row.

Also accepts the props of the primitive part it wraps.

Accessibility

The root has the progressbar role with aria-valuenow reflecting the value.
ProgressLabel provides the accessible name. Without it, pass aria-label.
When value is null, aria-valuenow is omitted to signal an indeterminate state.

Notes

Styling hooks: data-slot values progress, progress-track, progress-indicator, progress-label and progress-value.
The track uses muted and the indicator uses primary; the indicator animates width changes.

Progress renders a thin track with an indicator whose width follows value. The width animates with a Reanimated spring, clamped between 0 and 100 percent. Any children, such as ProgressLabel and ProgressValue, are placed in a row above the bar.

Use it for uploads, downloads and other tasks with a known amount of work.

Installation

$ pnpm dlx shadcn@latest add @esuiss-rn/progress

See Installation for the components.json setup. Or use the suiss/ui CLI:

$ pnpm dlx @esuiss/ui@latest add progress
