# 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.

Source: https://ui.suiss.app/docs/components/progress

**React**

**Example**

```tsx
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

```bash title="Terminal"
npx shadcn@latest add @esuiss/progress
```

Works in any project with a `components.json`. See [Installation](https://ui.suiss.app/docs/installation#add-components) for the one-line registry setup. Or use the suiss/ui CLI:

```bash title="Terminal"
npx @esuiss/ui@latest add progress
```

### Manual

1. Install the dependencies and add the [`cn` helper](https://ui.suiss.app/docs/installation#the-cn-helper):

```bash title="Terminal"
npm install @base-ui/react
```

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

```tsx title="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)}
      {...props}
    >
      {children}
      <ProgressTrack>
        <ProgressIndicator />
      </ProgressTrack>
    </ProgressPrimitive.Root>
  )
}

function ProgressTrack({ className, ...props }: ProgressPrimitive.Track.Props) {
  return (
    <ProgressPrimitive.Track
      className={cn(
        "relative flex h-1 w-full items-center overflow-x-hidden rounded-full bg-muted",
        className
      )}
      data-slot="progress-track"
      {...props}
    />
  )
}

function ProgressIndicator({
  className,
  ...props
}: ProgressPrimitive.Indicator.Props) {
  return (
    <ProgressPrimitive.Indicator
      data-slot="progress-indicator"
      className={cn("h-full bg-primary transition-[width]", className)}
      {...props}
    />
  )
}

function ProgressLabel({ className, ...props }: ProgressPrimitive.Label.Props) {
  return (
    <ProgressPrimitive.Label
      className={cn("text-sm", className)}
      data-slot="progress-label"
      {...props}
    />
  )
}

function ProgressValue({ className, ...props }: ProgressPrimitive.Value.Props) {
  return (
    <ProgressPrimitive.Value
      className={cn(
        "ms-auto text-sm text-muted-foreground tabular-nums",
        className
      )}
      data-slot="progress-value"
      {...props}
    />
  )
}

export {
  Progress,
  ProgressIndicator,
  ProgressLabel,
  ProgressTrack,
  ProgressValue,
}
```

3. Update the import paths to match your project.

## Usage

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

```tsx
<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.

**Example**

```tsx
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`.

**Example**

```tsx
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.

**Example**

```tsx
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

- `Progress`
- `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.

**React Native, SwiftUI, Jetpack Compose**

![Preview](https://ui.suiss.app/previews/components-progress--default.light.webp)

```tsx
import * as React from "react"
import { Progress } from "@/components/ui/progress"

function ProgressDemo() {
  const [value, setValue] = React.useState(13)
  React.useEffect(() => {
    const timer = setTimeout(() => setValue(66), 500)
    return () => clearTimeout(timer)
  }, [])
  return <Progress value={value} />
}

export function ProgressExample() {
  return (
    <ProgressDemo />
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct ProgressDelayed: View {
  @State private var value = 13.0

  var body: some View {
    ProgressView(value: value, total: 100)
      .progressViewStyle(.bar)
      .task {
        try? await Task.sleep(for: .milliseconds(500))
        value = 66
      }
  }
}
```

```kotlin
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.runtime.Composable
import androidx.compose.runtime.LaunchedEffect
import androidx.compose.runtime.getValue
import androidx.compose.runtime.mutableFloatStateOf
import androidx.compose.runtime.saveable.rememberSaveable
import androidx.compose.runtime.setValue
import androidx.compose.ui.Modifier
import com.esuiss.ui.components.Progress
import kotlinx.coroutines.delay

@Composable
fun ProgressDefault() {
    var value by rememberSaveable { mutableFloatStateOf(13f) }
    LaunchedEffect(Unit) {
        delay(500)
        value = 66f
    }
    Progress(value, Modifier.fillMaxWidth())
}
```

`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.

**SwiftUI**

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

- `swift/Theme/Theme.swift`: [source](https://github.com/e-suiss/ui/blob/main/packages/mobile/swiftui/Sources/EsuissUI/Theme/Theme.swift)

- `swift/Theme/Tokens.swift`: [source](https://github.com/e-suiss/ui/blob/main/packages/mobile/swiftui/Sources/EsuissUI/Theme/Tokens.swift)

3. Copy the source and every file it uses:

```swift title="swift/Components/Progress.swift"
import SwiftUI

public struct BarProgressViewStyle: ProgressViewStyle {
  public init() {}

  public func makeBody(configuration: Configuration) -> some View {
    BarProgress(configuration: configuration)

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

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

```tsx
<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.

![Preview](https://ui.suiss.app/previews/components-progress--with-label.light.webp)

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

function WithLabelDemo() {
  const [value, setValue] = React.useState(0)
  React.useEffect(() => {
    const timer = setInterval(() => {
      setValue((current) => (current >= 100 ? 0 : current + 10))
    }, 600)
    return () => clearInterval(timer)
  }, [])
  return (
    <Progress value={value}>
      <ProgressLabel>Uploading</ProgressLabel>
      <ProgressValue />
    </Progress>
  )
}

export function ProgressWithLabelExample() {
  return (
    <WithLabelDemo />
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct ProgressWithLabel: View {
  @State private var value = 0

  var body: some View {
    ProgressView(value: Double(value), total: 100) {
      Text("Uploading")
    } currentValueLabel: {
      Text(verbatim: "\(value)%")
    }
    .progressViewStyle(.bar)
    .task {
      while !Task.isCancelled {
        try? await Task.sleep(for: .milliseconds(600))
        value = value >= 100 ? 0 : value + 10
      }
    }
  }
}
```

@Composable
fun ProgressWithLabel() {
    var value by rememberSaveable { mutableFloatStateOf(0f) }
    LaunchedEffect(Unit) {
        while (true) {
            delay(600)
            value = if (value >= 100f) 0f else value + 10f
        }
    }
    Progress(value, Modifier.fillMaxWidth(), label = "Uploading", showValue = true)
}
```

### Complete

A bar at 100 percent.

![Preview](https://ui.suiss.app/previews/components-progress--complete.light.webp)

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

export function ProgressCompleteExample() {
  return (
    <Progress value={100} />
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct ProgressCompleteExample: View {
  var body: some View {
    ProgressView(value: 100, total: 100)
      .progressViewStyle(.bar)
  }
}
```

```kotlin
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import com.esuiss.ui.components.Progress

@Composable
fun ProgressCompleteExample() {
    Progress(100f, Modifier.fillMaxWidth())
}
```

### Values

Bars at 0, 25, 50, 75 and 100 percent, the last with a custom indicator color.

![Preview](https://ui.suiss.app/previews/components-progress--values.light.webp)

```tsx
import { View } from "react-native"
import { Progress } from "@/components/ui/progress"

export function ProgressValuesExample() {
  return (
    <View className="w-full gap-4">
      <Progress value={0} />
      <Progress value={25} />
      <Progress value={50} />
      <Progress value={75} />
      <Progress value={100} indicatorClassName="bg-green-500" />
    </View>
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct ProgressValuesExample: View {
  var body: some View {
    VStack(spacing: 16) {
      ForEach([0.0, 25, 50, 75, 100], id: \.self) { value in
        ProgressView(value: value, total: 100)
          .progressViewStyle(.bar)
      }
    }
    .frame(maxWidth: .infinity)
  }
}
```

```kotlin
import androidx.compose.foundation.layout.Arrangement
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.fillMaxWidth
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp
import com.esuiss.ui.components.Progress

@Composable
fun ProgressValues() {
    Column(Modifier.fillMaxWidth(), verticalArrangement = Arrangement.spacedBy(16.dp)) {
        listOf(0f, 25f, 50f, 75f, 100f).forEach { Progress(it, Modifier.fillMaxWidth()) }
    }
}
```

## 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.
