Svelte Toasts - Flowbite

Push notifications to your users using the toast component and choose from multiple sizes, colors, styles, and positions

The toast component can be used to enhance your website’s interactivity by pushing notifications to your visitors. You can choose from multiple styles, colors, sizes, and positions and even dismiss the component.

Setup #

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
</script>

Default toast #

Use this simple toast component with an icon, message, and dismissable close button to show alert messages to your website visitors.

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { FireOutline } from "flowbite-svelte-icons";
</script>

<Toast>
  {#snippet icon()}
    <FireOutline class="text-primary-500 bg-primary-100 dark:bg-primary-800 dark:text-primary-200 h-6 w-6" />
  {/snippet}
  Set yourself free.
</Toast>

ToastContainer #

Use the following example with ToastContainer to stack toasts vertically on the screen.

  • Svelte
<script lang="ts">
  import { Toast, ToastContainer, P, Button, Heading } from "flowbite-svelte";
  import { fly } from "svelte/transition";
  import { onDestroy } from "svelte";

  type ToastColor = "green" | "red" | "yellow" | "blue";

  interface ToastItem {
    id: number;
    message: string;
    color: ToastColor;
    timeoutId?: ReturnType<typeof setTimeout>;
    visible: boolean;
  }

  let toasts = $state<ToastItem[]>([]);
  let nextId = $state(1);

  const messages: Record<ToastColor, string> = {
    green: "Successfully saved!",
    blue: "New message received",
    yellow: "Please review your changes",
    red: "Operation failed"
  };

  function addToast(color?: ToastColor) {
    const selectedColor = color || (["green", "blue", "yellow", "red"][Math.floor(Math.random() * 4)] as ToastColor);
    const newToast: ToastItem = {
      id: nextId,
      message: messages[selectedColor],
      color: selectedColor,
      visible: true
    };

    // Auto-dismiss after 5 seconds
    const timeoutId = setTimeout(() => {
      dismissToast(newToast.id);
    }, 5000);
    newToast.timeoutId = timeoutId;

    toasts = [...toasts, newToast];
    nextId++;
  }

  function dismissToast(id: number) {
    // Clear timeout if it exists
    const toast = toasts.find((t) => t.id === id);
    if (toast?.timeoutId) {
      clearTimeout(toast.timeoutId);
    }

    // Set visible to false to trigger outro transition
    toasts = toasts.map((t) => (t.id === id ? { ...t, visible: false } : t));

    setTimeout(() => {
      toasts = toasts.filter((t) => t.id !== id);
    }, 300); // Slightly longer than transition duration
  }

  function handleClose(id: number) {
    return () => {
      dismissToast(id);
    };
  }

  onDestroy(() => {
    // Clear all pending timeouts on unmount
    toasts.forEach((toast) => {
      if (toast.timeoutId) {
        clearTimeout(toast.timeoutId);
      }
    });
  });
</script>

<ToastContainer position="top-right">
  {#each toasts as toast (toast.id)}
    <Toast color={toast.color} dismissable={true} transition={fly} params={{ x: 200, duration: 800 }} class="w-64" onclose={handleClose(toast.id)} bind:toastStatus={toast.visible}>

</div>

Colors #

Use the color prop to easily change the colors of the icons. Set the color prop to undefined and use the class prop to customize your desired icon styles.

Usually, green, red, and orange are used to show success, danger, or warning alert messages to your users. See the first three examples below.

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { CheckCircleSolid, ExclamationCircleSolid, FireOutline, CloseCircleSolid } from "flowbite-svelte-icons";
</script>

<Toast color="green">
  {#snippet icon()}
    <CheckCircleSolid class="h-5 w-5" />
    <span class="sr-only">Check icon</span>
  {/snippet}
  Item moved successfully.
</Toast>

<Toast color="red">
  {#snippet icon()}
    <CloseCircleSolid class="h-5 w-5" />
    <span class="sr-only">Error icon</span>
  {/snippet}
  Item has been deleted.
</Toast>

<Toast color="red">
  {#snippet icon()}
    <ExclamationCircleSolid class="h-5 w-5" />
    <span class="sr-only">Warning icon</span>
  {/snippet}
  Improve password difficulty.
</Toast>

    <FireOutline class="h-6 w-6" />
  {/snippet}
  Purple
</Toast>

<Toast color={undefined} class="bg-pink-100 text-pink-500 dark:bg-pink-800 dark:text-pink-200">
  {#snippet icon()}
    <FireOutline class="h-6 w-6" />
  {/snippet}
  Customize your colors.
</Toast>

Simple toast #

This component can be used to show simple messages and notifications without the use of a close button.

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { PaperPlaneOutline } from "flowbite-svelte-icons";
</script>

<Toast dismissable={false}>
  {#snippet icon()}
    <PaperPlaneOutline class="text-primary-600 dark:text-primary-500 h-5 w-5 rotate-45" />
  {/snippet}
  <div class="ps-4 text-sm font-normal">Message sent successfully.</div>
</Toast>

Icons #

For the right positioning of the icon use: {#snippet icon()}...{/snippet}.

You can use any icon components.

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { ImageOutline } from "flowbite-svelte-icons";
</script>

<Toast>
  {#snippet icon()}
    <ImageOutline class="h-6 w-6" />
  {/snippet}
  There is a box icon.
</Toast>

<Toast>No icon at all.</Toast>

Autohide example #

  • Svelte
<script lang="ts">
  import { Toast, Button } from "flowbite-svelte";
  import { slide } from "svelte/transition";
  import { CheckCircleSolid } from "flowbite-svelte-icons";

  let toastStatus = true;
  let counter = 6;

  function trigger() {
    toastStatus = true;
    counter = 6;
    timeout();
  }

  function timeout() {
    if (--counter > 0) return setTimeout(timeout, 1000);
    toastStatus = false;
  }
</script>

<div class="flex gap-10">
  <Button onclick={trigger} class="my-3">Restart</Button>
  <Toast dismissable={false} transition={slide} bind:toastStatus>
    {#snippet icon()}
      <CheckCircleSolid class="h-5 w-5" />
    {/snippet}
    Autohide in {counter}s.
  </Toast>
</div>

Transitions #

You can use one of Svelte/easing.

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { slide, scale } from "svelte/transition";
  import { quintOut } from "svelte/easing";
  import { CheckCircleSolid } from "flowbite-svelte-icons";
</script>

<Toast transition={slide}>
  {#snippet icon()}
    <CheckCircleSolid class="h-6 w-6" />
  {/snippet}
  Transition type: slide
</Toast>

<Toast transition={scale} params={{ delay: 250, duration: 300, easing: quintOut }}>
  {#snippet icon()}
    <CheckCircleSolid class="h-6 w-6" />
  {/snippet}
  Transition type: scale, delay: 250, duration: 300, easing: quintOut
</Toast>

<Toast params={{ delay: 250, duration: 1000 }}>
  {#snippet icon()}
    <CheckCircleSolid class="h-6 w-6" />
  {/snippet}
  Transition type: fade, delay: 250, duration: 1000
</Toast>

Blur examples #

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { blur } from "svelte/transition";
  import { BellOutline } from "flowbite-svelte-icons";
</script>

<Toast transition={blur} color="purple" params={{ amount: 10 }} class="mb-4">
  {#snippet icon()}
    <BellOutline class="h-6 w-6" />
  {/snippet}
  Transition type: blur, amount: 10
</Toast>

<Toast transition={blur} color="purple" params={{ amount: 50, delay: 1000 }}>
  {#snippet icon()}
    <BellOutline class="h-6 w-6" />
  {/snippet}
  Transition type: blur, amount: 50, delay 1000
</Toast>

Fly examples #

  • Svelte
<script lang="ts">
  import { Toast } from "flowbite-svelte";
  import { fly } from "svelte/transition";
  import { DownloadOutline } from "flowbite-svelte-icons";
</script>

<Toast transition={fly} params={{ x: 200 }} color="green" class="mb-4">
  {#snippet icon()}
    <DownloadOutline class="h-6 w-6" />
  {/snippet}
  Transition type: fly right
</Toast>

<Toast transition={fly} params={{ y: 200 }} color="green">
  {#snippet icon()}
    <DownloadOutline class="h-6 w-6" />
  {/snippet}
  Transition type: fly down
</Toast>

Undo button #

Use this toast component to also show an “undo” button to reverse the action of the user.

  • Svelte
<Toast classes={{ content: "w-full text-sm font-normal flex items-center justify-between" }}>
  Conversation archived.
  <a class="text-primary-600 hover:bg-primary-100 dark:text-primary-500 ms-auto rounded-lg p-1.5 font-medium dark:hover:bg-gray-700" href="/">Undo</a>
</Toast>

Advanced examples #

If the toast content grows to multiple lines we need to switch off the items-center alignment. Notice how the examples below achieve that by setting align={flase} property.

Toast message #

This component can be used to show messages and a CTA button when receiving chat messages, comment notifications, and other use cases.

  • Svelte
<script lang="ts">
  import { Toast, Avatar, Button } from "flowbite-svelte";
</script>

<Toast align={false} color={undefined}>
  {#snippet icon()}
    <Avatar src="/images/profile-picture-1.webp" class="h-8" />
  {/snippet}
  <div class="ms-3 text-sm font-normal">
    <span class="mb-1 text-sm font-semibold text-gray-900 dark:text-white">Jese Leos</span>
    <div class="mb-2 text-sm font-normal">Hi Neil, thanks for sharing your thoughts regarding Flowbite.</div>
    <Button size="xs">Reply</Button>
  </div>
</Toast>

Push notification #

This component can be used to show notifications for an action from another user such as posting a comment, receiving a like, being tagged. You can show an avatar, icon, message, and the time of the notification.

  • Svelte
<script lang="ts">
  import { Toast, Avatar } from "flowbite-svelte";
</script>

<Toast align={false}>
  <span class="font-semibold text-gray-900 dark:text-white">New notification</span>
  <div class="mt-3 flex items-center">
    <Avatar src="/images/profile-picture-3.webp" />
    <div class="ms-3">
      <h4 class="text-sm font-semibold text-gray-900 dark:text-white">Bonnie Green</h4>
      <div class="text-sm font-normal">commented on your photo</div>
      <span class="text-primary-600 dark:text-primary-500 text-xs font-medium">a few seconds ago</span>
    </div>
  </div>
</Toast>

Interactive toast #

Use this interactive toast component to encourage users to make a certain action such as updating to the latest software version. You can set an icon, message, and two CTA buttons.

This is an example with the icon and extra content at the same time.

  • Svelte
<script lang="ts">
  import { Toast, Button } from "flowbite-svelte";
  import { CameraPhotoOutline } from "flowbite-svelte-icons";
</script>

<Toast align={false}>
  {#snippet icon()}
    <CameraPhotoOutline class="h-6 w-6" />
  {/snippet}

  <span class="font-semibold text-gray-900 dark:text-white">Update available</span>
  <div class="mt-3">
    <div class="mb-2 text-sm font-normal">A new software version is available for download.</div>
    <div class="grid grid-cols-2 gap-2">
      <Button size="xs" class="w-full">Update</Button>
      <Button size="xs" class="w-full" color="dark">Not now</Button>
    </div>
  </div>
</Toast>

Positioning #

Use the position property to position these toast components relative to the main content wrapper element from your document.

  • Svelte
<div class="relative h-56">
  <Toast dismissable={false} position="top-left">Top left positioning.</Toast>
  <Toast dismissable={false} position="top-right">Top right positioning.</Toast>
  <Toast dismissable={false} position="bottom-left">Bottom left positioning.</Toast>
  <Toast dismissable={false} position="bottom-right">Bottom right positioning.</Toast>
</div>

Events #

The Toast component extends HTMLAttributes<HTMLDivElement>, allowing you to use standard DOM events like onclick. Additionally, Toast provides a custom onclose prop to execute logic when the toast is dismissed. The following example demonstrates both.

  • Svelte
<Toast onclick={() => alert("Toast clicked")} onclose={() => alert("Toast closing")}>Click this toast or the close button to trigger an event.</Toast>

Component data #

The component has the following props, type, and default values. See types page for type information.
