svelte-sonner

An opinionated toast component for Svelte.

Based on emilkowalski's React implementation.

Install it:

npm i svelte-sonner
# or
yarn add svelte-sonner
# or
pnpm add svelte-sonner

Add <Toaster /> to your app, it will be the place where all your toasts will be rendered. After that, you can use toast() from anywhere in your app.

<script>
	import { Toaster, toast } from 'svelte-sonner';
</script>

<Toaster />
<button on:click={() => toast('My first toast')}>Give me a toast</button>

Most basic toast. You can customize it (and any other type) by passing an options object as the second argument.

toast('Event has been created');

With custom icon and description:

import Icon from './Icon.svelte';

toast('Event has been created', {
	description: 'Monday, January 3rd at 6:00pm',
	icon: Icon
});

Renders a checkmark icon in front of the message.

toast.success('Event has been created');

Renders a question mark icon in front of the message.

toast.info('Event has new information');

Renders a warning icon in front of the message.

toast.warning('Event has warning');

Renders an error icon in front of the message.

toast.error('Event has not been created');

Renders a button.

toast('Event has been created', {
	action: {
		label: 'Undo',
		onClick: () => console.log('Undo')
	}
});

Starts in a loading state and will update automatically after the promise resolves or fails.

toast.promise(() => new Promise((resolve) => setTimeout(resolve, 2000)), {
	loading: 'Loading',
	success: 'Success',
	error: 'Error'
});

You can pass a function to the success/error messages to incorporate the result/error of the promise.

toast.promise(promise, {
	loading: 'Loading...',
	success: (data) => {
		return `${data.name} has been added!`;
	},
	error: 'Error'
});

You can pass a component as the first argument instead of a string to render custom component while maintaining default styling. You can use the headless version below for a custom, unstyled toast.

toast(CustomComponent);

You can update a toast by using the toast function and passing it the id of the toast you want to update, the rest stays the same.

const toastId = toast('Sonner');

toast.success('Toast has been updated', {
	id: toastId
});

You can use toast.custom to render an unstyled toast with custom component while maintaining the functionality.

<script>
	import { createEventDispatcher } from 'svelte';

	const dispatch = createEventDispatcher();
</script>

<div>
	This is a custom component <button on:click={() => dispatch('closeToast')}>close</button>
</div>

import HeadlessToast from './HeadlessToast.svelte';

toast.custom(HeadlessToast);

You can change the theme using the theme prop. Default theme is light.

<Toaster theme="dark" />

You can change the position through the position prop on the <Toaster /> component. Default is bottom-right.

<!-- Available positions -->
<!-- top-left, top-center, top-right, bottom-left, bottom-center, bottom-right -->

<Toaster position="top-center" />

Toasts can also be expanded by default through the expand prop. You can also change the amount of visible toasts which is 3 by default.

<Toaster expand visibleToasts={9} />

Styling can be done globally via toastOptions, this way every toast will have the same styling.

<Toaster
	toastOptions={{
		style: 'background: red;',
		class: 'my-toast',
		descriptionClass: 'my-toast-description'
	}}
/>

You can also use the same props when calling toast to style a specific toast.

toast('Event has been created', {
	style: 'background: red;',
	class: 'my-toast',
	descriptionClass: 'my-toast-description'
});

The preferred way to style the toasts with tailwind is by using the unstyled prop. That will give you an unstyled toast which you can then style with tailwind.

<Toaster
	toastOptions={{
		unstyled: true,
		classes: {
			toast: 'bg-blue-400',
			title: 'text-red-400',
			description: 'text-red-400',
			actionButton: 'bg-zinc-400',
			cancelButton: 'bg-orange-400',
			closeButton: 'bg-lime-400'
		}
	}}
/>

You can do the same when calling toast().

toast('Hello World', {
	unstyled: true,
	classes: {
		toast: 'bg-blue-400',
		title: 'text-red-400 text-2xl',
		description: 'text-red-400',
		actionButton: 'bg-zinc-400',
		cancelButton: 'bg-orange-400',
		closeButton: 'bg-lime-400'
	}
});

Styling per toast type is also possible.

<Toaster
	toastOptions={{
		unstyled: true,
		classes: {
			error: 'bg-red-400',
			success: 'text-green-400',
			warning: 'text-yellow-400',
			info: 'bg-blue-400'
		}
	}}
/>

You can change the default icons using slots:

<Toaster>
	<LoadingIcon slot="loading-icon" />
	<SuccessIcon slot="success-icon" />
	<ErrorIcon slot="error-icon" />
	<InfoIcon slot="info-icon" />
	<WarningIcon slot="warning-icon" />
</Toaster>

Add a close button to all toasts that shows on hover by adding the closeButton prop.

<Toaster closeButton />

You can make error and success state more colorful by adding the richColors prop.

<Toaster richColors />

Offset from the edges of the screen.

<Toaster offset="80px" />

To remove a toast programmatically use toast.dismiss(id).

const toastId = toast('Event has been created');

toast.dismiss(toastId);

To remove a toast from inside a custom component, dispatch closeToast:

import { createEventDispatcher } from 'svelte';

const dispatch = createEventDispatcher();

dispatch('closeToast');

You can also dismiss all toasts at once by calling toast.dismiss() without an id.

toast.dismiss();

You can change the duration of each toast by using the duration property, or change the duration of all toasts like this:

<Toaster duration={10000} />

toast('Event has been created', {
	duration: 10000
});

// Persisent toast
toast('Event has been created', {
	duration: Number.POSITIVE_INFINITY
});

You can pass onDismiss and onAutoClose callbacks. onDismiss gets fired when either the close button gets clicked or the toast is swiped. onAutoClose fires when the toast disappears automatically after it's timeout (duration prop).

toast('Event has been created', {
	onDismiss: (t) => console.log(`Toast with id ${t.id} has been dismissed`),
	onAutoClose: (t) => console.log(`Toast with id ${t.id} has been closed automatically`)
});

You can focus on the toast area by pressing ⌥/alt + T. You can override it by providing an array of event.code values for each key.

<Toaster hotkey={['KeyC']} />
