# Empty

A centered placeholder for screens and lists that have no content yet.

Empty is an open-source mobile component from suiss/uim for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

```tsx
import { FolderOpenIcon } from "phosphor-react-native"
import { Button } from "@/components/ui/button"
import { Empty, EmptyContent, EmptyDescription, EmptyHeader, EmptyMedia, EmptyTitle } from "@/components/ui/empty"
import { Icon } from "@/components/ui/icon"
import { Text } from "@/components/ui/text"

export function EmptyExample() {
  return (
    <Empty>
      <EmptyHeader>
        <EmptyMedia variant="icon">
          <Icon as={FolderOpenIcon} />
        </EmptyMedia>
        <EmptyTitle>No projects yet</EmptyTitle>
        <EmptyDescription>
          You haven't created any projects yet. Get started by creating your
          first project.
        </EmptyDescription>
      </EmptyHeader>
      <EmptyContent>

        </Button>
      </EmptyContent>
    </Empty>
  )
}
```

```swift

`Empty` is a centered column that fills the available space and holds an `EmptyHeader` with optional `EmptyMedia`, an `EmptyTitle` and an `EmptyDescription`, followed by `EmptyContent` for actions. Text is centered and the header and content are limited to a readable width.

Use it for empty lists, search results with no matches and first-run screens.

## Installation

```bash title="Terminal"
npx @esuiss/uim@latest add empty
```

```bash title="Terminal"
npx @esuiss/uim@latest add empty --platform swift
```

```bash title="Terminal"
npx @esuiss/uim@latest add empty --platform kotlin
```

The CLI also adds what it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text).

### Manual

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install class-variance-authority cn
```

2. Add the pieces it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text).

3. Copy the source into `components/ui/empty.tsx`:

```tsx title="uniwind/components/ui/empty.tsx"
import { cva, type VariantProps } from "class-variance-authority"
import { cn } from "cn"
import { View, type ViewProps } from "react-native"
import { IconClassContext } from "@/components/ui/icon"
import { Text, TextClassContext } from "@/components/ui/text"

function Empty({ className, ...props }: ViewProps) {
  return (
    <TextClassContext.Provider value="text-center">
      <View
        className={cn(
          "w-full min-w-0 flex-1 flex-col items-center justify-center gap-4 rounded-2xl p-12",
          className
        )}
        {...props}
      />
    </TextClassContext.Provider>
  )
}

function EmptyHeader({ className, ...props }: ViewProps) {
  return (
    <View
      className={cn("w-full max-w-sm flex-col items-center gap-2", className)}
      {...props}
    />
  )
}

const emptyMediaVariants = cva("mb-2 shrink-0 items-center justify-center", {
  variants: {
    variant: {
      default: "bg-transparent",
      icon: "size-10 rounded-lg bg-surface-secondary",
    },
  },
  defaultVariants: {
    variant: "default",
  },
})

function EmptyMedia({
  className,
  variant = "default",
  ...props
}: ViewProps & VariantProps<typeof emptyMediaVariants>) {
  return (
    <IconClassContext.Provider
      value={variant === "icon" ? "size-5 text-label" : undefined}
    >
      <View
        accessible={false}
        importantForAccessibility="no-hide-descendants"
        className={cn(emptyMediaVariants({ variant }), className)}
        {...props}
      />
    </IconClassContext.Provider>
  )
}

function EmptyTitle({
  className,
  ...props
}: React.ComponentProps<typeof Text>) {
  return (
    <Text
      role="heading"
      className={cn("text-center text-lg font-semibold text-label", className)}
      {...props}
    />
  )
}

function EmptyDescription({
  className,
  ...props
}: React.ComponentProps<typeof Text>) {
  return (
    <Text
      className={cn("text-center text-sm text-label-secondary", className)}
      {...props}
    />
  )
}

function EmptyContent({ className, ...props }: ViewProps) {
  return (
    <View
      className={cn(
        "w-full max-w-sm min-w-0 flex-col items-center gap-4",
        className
      )}
      {...props}
    />
  )
}

export {
  Empty,
  EmptyContent,
  EmptyDescription,
  EmptyHeader,
  EmptyMedia,
  EmptyTitle,
}
```

4. Update the import paths to match your project.

**NativeWind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install class-variance-authority cn
```

2. Add the pieces it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text).

3. Copy the source into `components/ui/empty.tsx`:

```tsx title="nativewind/components/ui/empty.tsx"
import { cva, type VariantProps } from "class-variance-authority"
import { cn } from "cn"
import { View, type ViewProps } from "react-native"
import { IconClassContext } from "@/components/ui/icon"
import { Text, TextClassContext } from "@/components/ui/text"

function Empty({ className, ...props }: ViewProps) {
  return (
    <TextClassContext.Provider value="text-center">

          "w-full min-w-0 flex-1 flex-col items-center justify-center gap-4 rounded-2xl p-12",
          className
        )}
        {...props}
      />
    </TextClassContext.Provider>
  )
}

function EmptyHeader({ className, ...props }: ViewProps) {
  return (
    <View
      className={cn("w-full max-w-sm flex-col items-center gap-2", className)}

    />
  )
}

const emptyMediaVariants = cva("mb-2 shrink-0 items-center justify-center", {

    </IconClassContext.Provider>
  )
}

function EmptyTitle({

  return (
    <Text
      className={cn("text-center text-sm text-label-secondary", className)}
      {...props}
    />
  )
}

function EmptyContent({ className, ...props }: ViewProps) {
  return (
    <View
      className={cn(
        "w-full max-w-sm min-w-0 flex-col items-center gap-4",
        className
      )}

    />
  )
}

export {
  Empty,
  EmptyContent,
  EmptyDescription,
  EmptyHeader,
  EmptyMedia,
  EmptyTitle,
}
```

4. Update the import paths to match your project.

**StyleSheet**

1. Add the pieces it builds on: [Icon](/docs/components/icon), [Text](/docs/components/text).

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

```tsx title="stylesheet/components/ui/empty.tsx"
import { StyleSheet, View, type ViewProps } from "react-native"
import { IconSizeContext } from "@/components/ui/icon"

    borderRadius: radius["2xl"],
    padding: 48,
  },
  header: {

    justifyContent: "center",
  },
  mediaIcon: { width: 40, height: 40, borderRadius: radius.lg },
  title: { ...fontSize.lg, fontWeight: "600", textAlign: "center" },
  description: { ...fontSize.sm, textAlign: "center" },
  content: {
    width: "100%",
    maxWidth: 384,
    minWidth: 0,
    flexDirection: "column",
    alignItems: "center",
    gap: 16,
  },
})

function Empty({ style, ...props }: ViewProps) {
  return (
    <TextStyleContext.Provider value={{ textAlign: "center" }}>
      <View style={[styles.root, style]} {...props} />
    </TextStyleContext.Provider>
  )
}

function EmptyHeader({ style, ...props }: ViewProps) {
  return <View style={[styles.header, style]} {...props} />
}

function EmptyMedia({
  style,
  variant = "default",
  ...props
}: ViewProps & { variant?: "default" | "icon" }) {
  const { colors } = useTheme()
  const icon = variant === "icon"
  return (

          style,
        ]}
        {...props}
      />
    </IconSizeContext.Provider>
  )
}

function EmptyTitle({ style, ...props }: React.ComponentProps<typeof Text>) {
  const { colors } = useTheme()
  return (
    <Text
      role="heading"
      style={[styles.title, { color: colors.label }, style]}
      {...props}
    />
  )
}

function EmptyDescription({
  style,
  ...props

  const { colors } = useTheme()
  return (

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:

  </EmptyContent>
</Empty>
```

`EmptyMedia` has two variants: `default` shows its child as is, such as an illustration, and `icon` puts an `Icon` in a small rounded tile. Put buttons or links in `EmptyContent`.

Add a background class such as `bg-surface-secondary` to `Empty` for a filled panel.

## Examples

### Muted

A filled panel with only a title and description.

```tsx
import { Empty, EmptyDescription, EmptyHeader, EmptyTitle } from "@/components/ui/empty"

export function EmptyMutedExample() {
  return (
    <Empty className="bg-surface-secondary">
      <EmptyHeader>
        <EmptyTitle>No results</EmptyTitle>
        <EmptyDescription>Try a different search.</EmptyDescription>
      </EmptyHeader>
    </Empty>
  )
}
```

```swift
import EsuissUI
import SwiftUI

struct EmptyMutedExample: View {
  var body: some View {
    Empty {
      EmptyHeader {
        EmptyTitle("No results")
        EmptyDescription("Try a different search.")
      }
    }
    .background(Color.surfaceSecondary, in: RoundedRectangle(cornerRadius: Radius.xl2, style: .continuous))
  }
}
```

```kotlin
import androidx.compose.foundation.background
import androidx.compose.foundation.shape.RoundedCornerShape
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import com.esuiss.ui.components.Empty
import com.esuiss.ui.components.EmptyDescription
import com.esuiss.ui.components.EmptyHeader

import com.esuiss.ui.theme.Radius

@Composable
fun EmptyMuted() {
    Empty(Modifier.background(EsuissTheme.colors.surfaceSecondary, RoundedCornerShape(Radius.xl2))) {
        EmptyHeader {
            EmptyTitle("No results")
            EmptyDescription("Try a different search.")
        }
    }

## API Reference

### Empty

Centered container.

### EmptyHeader

Column for media, title and description.

### EmptyMedia

Decorative icon or illustration.

### EmptyTitle

Heading.

### EmptyDescription

Supporting text.

### EmptyContent

Area for actions.

## Accessibility

- `EmptyTitle` has the `heading` role.
- `EmptyMedia` is hidden from screen readers, so the title and description must carry the message.

## Notes

- Uses `bg-surface-secondary`, `text-label` and `text-label-secondary` tokens; light and dark follow the system appearance.
