Progress

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:

components/ui/progress.tsx

"use client"

import { Progress as ProgressPrimitive } from "@base-ui/react/progress"
import { cn } from "@/lib/utils"

function Progress({
  className,
  children,
  value,
  ...props
}: ProgressPrimitive.Root.Props) {
  return (
    <ProgressPrimitive.Root
      value={value}
      data-slot="progress"
      className={cn("flex flex-wrap gap-3", className)}

Update the import paths to match your project.

Usage

import { Progress, ProgressTrack, ProgressIndicator, ProgressLabel, ProgressValue } from "@/components/ui/progress"

<div className="w-80">
  <Progress value={60} aria-label="Upload progress" />
</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.

import {
  Progress,
  ProgressLabel,
  ProgressValue,
} from "@/components/ui/progress"

export default function ProgressWithLabel() {
  return (
    <div className="w-80">
      <Progress value={42}>
        <ProgressLabel>Uploading files</ProgressLabel>
        <ProgressValue />
      </Progress>
    </div>
  )
}

Complete

A labelled bar at 100.

import {
  Progress,
  ProgressLabel,
  ProgressValue,
} from "@/components/ui/progress"

export default function ProgressComplete() {
  return (
    <div className="w-80">
      <Progress value={100}>
        <ProgressLabel>Uploading files</ProgressLabel>
        <ProgressValue />
      </Progress>
    </div>
  )
}

Indeterminate

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

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

export default function ProgressIndeterminate() {
  return (
    <div className="w-80">
      <Progress value={null}>
        <ProgressLabel>Preparing export</ProgressLabel>
      </Progress>
    </div>
  )
}

API Reference

Anatomy3 parts

</Progress>

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.

Usage

import { Progress, ProgressTrack, ProgressIndicator, ProgressLabel, ProgressValue } from "@/components/ui/progress"

<ProgressDemo />

Set value between min and max (0 and 100 by default). Pass null when the progress is unknown.

Add a ProgressLabel and a ProgressValue as children to show a caption and the formatted value; the value is pushed to the end of the row. Format the value with format and locale.

Style the bar with trackClassName and indicatorClassName. ProgressTrack and ProgressIndicator are also exported for custom layouts.

Examples

With label

A bar with a label and a live percentage value.

API Reference

Progress

Root that holds the value and renders the track and indicator.

Prop	Type	Default	Description
`trackClassName`	`string`	-	Extra classes for the track.
`indicatorClassName`	`string`	-	Extra classes for the indicator.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Root>.

ProgressTrack

Background bar.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Track>.

ProgressIndicator

Animated fill that shows the current value.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Indicator>.

ProgressLabel

Caption text above the bar.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Label>.

ProgressValue

Formatted value text, aligned to the end.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Value>.

Accessibility

The root has the progressbar role and reports min, max, the current value and a value text, so VoiceOver and TalkBack announce the progress.
Use getAccessibilityValueText to customize the announced text.

Notes

The track uses bg-muted and the indicator bg-primary.
Label and value text use text-foreground and text-muted-foreground, with tabular numbers for the value.
Light and dark colors follow the system appearance.

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

Usage

import { Progress, ProgressTrack, ProgressIndicator, ProgressLabel, ProgressValue } from "@/components/ui/progress"

<ProgressDemo />

Set value between min and max (0 and 100 by default). Pass null when the progress is unknown.

Add a ProgressLabel and a ProgressValue as children to show a caption and the formatted value; the value is pushed to the end of the row. Format the value with format and locale.

Style the bar with trackClassName and indicatorClassName. ProgressTrack and ProgressIndicator are also exported for custom layouts.

Examples

With label

A bar with a label and a live percentage value.

iOS

import * as React from "react"
import { Progress, ProgressLabel, ProgressValue } from "@/components/ui/progress"

function WithLabelDemo() {
  const [value, setValue] = React.useState(0)

    const timer = setInterval(() => {

API Reference

Progress

Root that holds the value and renders the track and indicator.

Prop	Type	Default	Description
`trackClassName`	`string`	-	Extra classes for the track.
`indicatorClassName`	`string`	-	Extra classes for the indicator.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Root>.

ProgressTrack

Background bar.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Track>.

ProgressIndicator

Animated fill that shows the current value.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Indicator>.

ProgressLabel

Caption text above the bar.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Label>.

ProgressValue

Formatted value text, aligned to the end.

Also accepts the props of React.ComponentProps<typeof ProgressPrimitive.Value>.

Accessibility

The root has the progressbar role and reports min, max, the current value and a value text, so VoiceOver and TalkBack announce the progress.
Use getAccessibilityValueText to customize the announced text.

Notes

The track uses bg-muted and the indicator bg-primary.
Label and value text use text-foreground and text-muted-foreground, with tabular numbers for the value.
Light and dark colors follow the system appearance.
