Ding

Toasts with real spring physics.
One toast that morphs in place. No dependencies. React, Svelte or plain DOM.

Why Ding

• One toast at a time. A new call morphs the toast on screen instead of stacking a second one.
• Real springs. Size, shape and text move on a spring solver, so interrupting an animation keeps its momentum.
• No stylesheet. Styles are injected from JavaScript. Nothing to import.
• Light, dark and system themes, six positions, right-to-left support.
• Rich content. Description, avatar, buttons, progress bar, a countdown line, small trailing text.
• Accessible by default. Persistent live regions, keyboard dismiss, prefers-reduced-motion.
• Optional sound. A soft built-in tone per status, or plug in your own.
• Strict TypeScript, ESM and CommonJS builds.

Install

npm i @yusufceng1z/ding-react    # React 18+
npm i @yusufceng1z/ding-svelte   # Svelte 5
npm i @yusufceng1z/ding          # plain DOM

Each framework package depends on the small @yusufceng1z/ding core, so you install only one.

Quick start

Render the toaster once, then call toast from anywhere.

React

import { Toaster, toast } from '@yusufceng1z/ding-react';

export default function App() {
  return (
    <>
      <Toaster position="top-center" theme="system" />
      <button onClick={() => toast.success('Saved')}>Save</button>
    </>
  );
}

Svelte 5

<script>
  import { Toaster, toast } from '@yusufceng1z/ding-svelte';
</script>

<Toaster position="top-center" theme="system" />
<button onclick={() => toast.success('Saved')}>Save</button>

Plain DOM

import { mountToaster, toast } from '@yusufceng1z/ding';

mountToaster({ position: 'top-center' });
toast.success('Saved');

Usage

toast.success('Saved');
toast.error('Payment failed', { description: 'Card declined' });
toast.warning('Storage almost full');
toast.info('New version available');
toast.loading('Uploading…');

Every call returns the toast id.

Promises and updates

toast.promise(save(), {
  loading: 'Saving…',
  success: 'Saved',
  error: (err) => `Could not save: ${err.message}`,
});

const id = toast.loading('Uploading photo…', { progress: 0 });
toast.update(id, { progress: 0.6 });
toast.update(id, { type: 'success', title: 'Photo uploaded', progress: null });

Only the newest caller can update the shared toast, so a slow request that finishes late cannot overwrite a newer message.

Actions

An onClick may return a patch. The toast then morphs in place instead of closing.

toast.success('Message deleted', {
  action: {
    label: 'Undo',
    onClick: () => {
      restore();
      return { type: 'info', title: 'Restored' };
    },
  },
});

Options

Option	Description
description	Second line of text
action	{ label, onClick }, the main button
secondary	{ label, onClick }, a quieter button beside the action
image	Avatar or thumbnail URL, replaces the status icon
meta	Small trailing text, such as now or ⌘V
progress	0 to 1, draws a thin bar at the bottom
duration	Milliseconds before it closes. 0 keeps it until dismissed. Default 5000
id	Reuse an id so repeated calls from one place stay one caller

Errors, loading toasts and toasts with a button stay until dismissed. Hover and keyboard focus pause the timer. Repeating the same toast adds a counter (×2).

Configure

toast.configure({
  position: 'bottom-right', // top-left, top-center, top-right, bottom-left, bottom-center, bottom-right
  theme: 'dark',            // system, light, dark
  sound: true,
  volume: 0.5,
});

toast.dismiss(id); // one toast
toast.dismiss();   // all

Sound

Off by default. With sound: true each status plays its own soft tone: success rises, error falls, warning double-taps, info is a single note. Loading is silent and progress updates never make a sound. Browsers keep audio locked until a click or key press.

To use your own sounds, pass a function. It receives success, error, warning, info or loading:

toast.configure({ sound: (type) => mySounds.play(type) });

Accessibility

• Messages go through persistent live regions: errors are assertive, everything else is polite.
• Esc dismisses. Alt + T moves focus into the toast.
• Respects prefers-reduced-motion.
• Mirrors automatically on right-to-left pages.
