# Bottom Bar

A bar pinned to the bottom of a screen for primary actions, which rises above the keyboard.

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

**React Native, SwiftUI, Jetpack Compose**

`BottomBar` is an animated `View` that adds bottom padding equal to the safe-area inset, or to the keyboard height while the keyboard is open, and animates between them with the keyboard's own timing. `BottomBarContent` adds the standard padding and spacing for the buttons inside.

Use it for the main call to action of a screen, such as checkout or a form submit button.

## Installation

**React Native**

```bash title="Terminal"
npx shadcn@latest add @esuiss-rn/bottom-bar
```

See [Installation](https://ui.suiss.app/docs/installation) for the `components.json` setup. Or use the suiss/ui CLI:

```bash title="Terminal"
npx @esuiss/ui@latest add bottom-bar
```

**SwiftUI**

```bash title="Terminal"
npx @esuiss/ui@latest add bottom-bar --platform swift
```

**Jetpack Compose**

```bash title="Terminal"
npx @esuiss/ui@latest add bottom-bar --platform kotlin
```

The CLI also adds what it builds on: [Screen](https://ui.suiss.app/docs/components/screen). On React Native it also adds the animated view `components/ui/animated-view.tsx`.

### Manual

**React Native**

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install cn react-native-reanimated react-native-safe-area-context react-native-worklets
```

2. Add the pieces it builds on: [Screen](https://ui.suiss.app/docs/components/screen), and the primitives `components/primitives/keyboard.tsx`, and the animated view `components/ui/animated-view.tsx` from the next step.

3. Copy the animated view into `components/ui/animated-view.tsx`:

- `uniwind/components/ui/animated-view.tsx`: [source](https://github.com/e-suiss/ui/blob/main/packages/mobile/uniwind/components/ui/animated-view.tsx)

4. Copy the source into `components/ui/bottom-bar.tsx`:

```tsx title="uniwind/components/ui/bottom-bar.tsx"
import { cn } from "cn"
import * as React from "react"
import { View, type ViewProps } from "react-native"
import {
  Easing,
  ReduceMotion,
  useAnimatedStyle,
  useSharedValue,
  withTiming,
} from "react-native-reanimated"
import { useSafeAreaInsets } from "react-native-safe-area-context"
import { useKeyboard } from "@/components/primitives/keyboard"
import { AnimatedView } from "@/components/ui/animated-view"
import { ScreenContext } from "@/components/ui/screen"

const EASING = Easing.bezier(0.17, 0.59, 0.4, 0.77)

function BottomBar({
  separator = false,
  className,
  style,
  ...props
}: ViewProps & {
  separator?: boolean
}) {
  const insets = useSafeAreaInsets()
  const screen = React.useContext(ScreenContext)
  const keyboard = useKeyboard()
  const consumed = screen?.edges.includes("bottom") ? insets.bottom : 0
  const target = Math.max(
    0,
    (keyboard.height > 0 ? keyboard.height : insets.bottom) - consumed
  )
  const padding = useSharedValue(target)

  React.useEffect(() => {
    padding.value = withTiming(target, {
      duration: keyboard.duration,
      easing: EASING,
      reduceMotion: ReduceMotion.System,
    })
  }, [target, keyboard.duration, padding])

  const animatedStyle = useAnimatedStyle(() => ({
    paddingBottom: padding.value,
  }))

  return (
    <AnimatedView
      className={cn(
        "bg-background",
        separator && "border-t border-border",
        className
      )}
      style={[animatedStyle, style]}
      {...props}
    />
  )
}

function BottomBarContent({ className, ...props }: ViewProps) {
  return <View className={cn("gap-2 px-4 py-3", className)} {...props} />

5. Update the import paths to match your project.

**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/BottomBar.swift"
import SwiftUI

public struct BottomBar<Content: View>: View {
  let separator: Bool
  let content: Content

  @Environment(\.screenBackground) private var background

  public init(separator: Bool = true, @ViewBuilder content: () -> Content) {
    self.separator = separator
    self.content = content()
  }

  public var body: some View {
    VStack(spacing: 0) {
      content
    }
    .frame(maxWidth: .infinity)
    .background(background.ignoresSafeArea(.container, edges: .bottom))
    .overlay(alignment: .top) {
      if separator {
        EsuissColor.border.frame(height: 1)
      }
    }
    .accessibilityElement(children: .contain)
  }
}

public struct BottomBarContent<Content: View>: View {
  let content: Content

  public init(@ViewBuilder content: () -> Content) {
    self.content = content()
  }

  public var body: some View {
    VStack(spacing: 8) {
      content
    }
    .padding(.horizontal, 16)
    .padding(.vertical, 12)
    .frame(maxWidth: .infinity)
  }
}
```

4. Add the files to your app target.

**Jetpack Compose**

1. Set `minSdk` to 24 or higher and add the dependencies:

```kotlin title="build.gradle.kts"
implementation(platform("androidx.compose:compose-bom:2026.09.00"))
implementation("androidx.compose.foundation:foundation")
implementation("androidx.compose.ui:ui")
```

2. Copy the theme files every view uses:

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

## Usage

```tsx
import { BottomBar, BottomBarContent } from "@/components/ui/bottom-bar"
```

```tsx
<Page>
  <BottomBar>
    <BottomBarContent>
      <Button size="lg" block>
        <Text>Continue</Text>
      </Button>
    </BottomBarContent>
  </BottomBar>
</Page>
```

Place `BottomBar` as the last child of the screen so it sits below the scrolling content. Stack buttons in `BottomBarContent`, or add `flex-row` to place them side by side.

Set `separator` to draw a hairline above the bar. Inside a `Screen` that already handles the bottom safe-area edge, the inset is not added twice.

## Examples

### With separator

A hairline above the bar with `separator`.

## API Reference

### BottomBar

Bottom container that follows the safe area and keyboard.

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `separator` | `boolean` | `false` | Draws a top border. Defaults to `false`. |

Also accepts the props of `ViewProps`.

### BottomBarContent

Padded area for the actions.

Also accepts the props of `ViewProps`.

## Accessibility

- The bar adds no role; each action inside provides its own.

## Notes

- The padding animation respects the system Reduce Motion setting.
- Uses `bg-background` and `border-border` tokens; light and dark follow the system appearance.
