# Toast

Display brief messages to users.

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});
</script>

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.info({
			title: 'Title',
			description: 'This is a description.',
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```

## Usage

This component acts as a Singleton - meaning you only implement a single instance (typically at the root scope of your app) and then reused it over and over. To do this, implement the `<Toast.Group>` at the root scope of your app (for SvelteKit this would be your root `+layout.svelte`), and use a shared `createToaster()` instance to trigger messages to that group from anywhere in your application.

## Type

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});
</script>

<div class="grid grid-cols-2 gap-2">
	<button
		class="btn preset-filled"
		onclick={() =>
			toaster.info({
				title: 'Info',
				description: 'This is an info toast.',
			})}
	>
		Info
	</button>
	<button
		class="btn preset-filled-success-500"
		onclick={() =>
			toaster.success({
				title: 'Success',
				description: 'This is a success toast.',
			})}
	>
		Success
	</button>
	<button
		class="btn preset-filled-warning-500"
		onclick={() =>
			toaster.warning({
				title: 'Warning',
				description: 'This is a warning toast.',
			})}
	>
		Warning
	</button>
	<button
		class="btn preset-filled-error-500"
		onclick={() =>
			toaster.error({
				title: 'Error',
				description: 'This is an error toast.',
			})}
	>
		Error
	</button>
</div>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```

Types can be specified in one of two ways:

* Via a trigger method: `toaster.{info|success|warning|error}()`
* Via the object key: `type: {info|success|warning|error}`

## Action

Include an optional action button.

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});
</script>

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.info({
			title: 'Toast',
			description: 'This is a toast message.',
			duration: Infinity,
			action: {
				label: 'Undo',
				onClick: () => {
					toaster.success({
						title: 'Task undone',
						description: 'The task has been undone.',
					});
				},
			},
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			{#if toast.action}
				<Toast.ActionTrigger>{toast.action.label}</Toast.ActionTrigger>
			{/if}
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```

## Closable

By passing `closable: false` you can disable the close button.

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});
</script>

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.info({
			title: 'Title',
			description: 'This is a description.',
			closable: false,
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			{#if toast.closable}
				<Toast.CloseTrigger />
			{/if}
		</Toast>
	{/snippet}
</Toast.Group>

```

## Placement

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({
		placement: 'bottom-end',
	});
</script>

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.info({
			title: 'Title',
			description: 'This is a description.',
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```

## Meta

Use the `meta` key to provide arbitrary data. Then use this to modify your Toast template.

```svelte
<script lang="ts">
	import { SkullIcon } from '@lucide/svelte';
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});
</script>

{#snippet skull()}
	<SkullIcon class="size-8" />
{/snippet}

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.info({
			title: 'Title',
			description: 'This is a description.',
			meta: {
				icon: skull,
			},
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			{@render toast.meta!.icon()}
			<Toast.Message>
				<Toast.Title class="flex gap-2 items-center">{toast.title}</Toast.Title>
				<Toast.Description>{toast.description} {toast.meta?.foo}</Toast.Description>
			</Toast.Message>
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```

## Promise

Use promises for asynchronous triggers.

```svelte
<script lang="ts">
	import { Toast, createToaster } from '@skeletonlabs/skeleton-svelte';

	const toaster = createToaster({});

	function generatePositiveNumber() {
		return new Promise<number>((resolve, reject) => {
			setTimeout(() => {
				const number = Math.random() - 0.5;
				if (number > 0) {
					resolve(number);
				} else {
					reject(number);
				}
			}, 2000);
		});
	}
</script>

<button
	class="btn preset-filled"
	onclick={() =>
		toaster.promise(generatePositiveNumber(), {
			loading: {
				title: 'Loading...',
				description: 'Please wait while generating your number',
			},
			success: (number) => ({
				title: 'Success',
				description: `Your number is ${number}`,
			}),
			error: (number) => ({
				title: 'Error',
				description: `Your number is ${number}`,
			}),
		})}
>
	Toast
</button>

<Toast.Group {toaster}>
	{#snippet children(toast)}
		<Toast {toast}>
			<Toast.Message>
				<Toast.Title>{toast.title}</Toast.Title>
				<Toast.Description>{toast.description}</Toast.Description>
			</Toast.Message>
			<Toast.CloseTrigger />
		</Toast>
	{/snippet}
</Toast.Group>

```
