Usage

Call Toaster.success / Toaster.error / Toaster.warning / Toaster.info / Toaster.loading imperatively; mount a single <Toaster /> once to render the list.

"use client";
import { Button, Toaster } from "@/ui";

export default function Demo() {
  return (
    <div className="flex flex-col items-center gap-4">
      <Toaster />
      <div className="flex flex-wrap justify-center gap-2">
        <Button
          onClick={() =>
            Toaster.success({
              title: "Changes saved",
              description: "Your profile has been updated.",
            })
          }
        >
          Success
        </Button>
        <Button
          onClick={() =>
            Toaster.error({
              title: "Upload failed",
              description: "The file exceeds the 10 MB limit.",
            })
          }
        >
          Error
        </Button>
        <Button
          onClick={() =>
            Toaster.warning({
              title: "Storage almost full",
              description: "9.2 GB of 10 GB used.",
            })
          }
        >
          Warning
        </Button>
        <Button
          onClick={() =>
            Toaster.info({
              title: "New version available",
              description: "Reload to update to v2.4.0.",
            })
          }
        >
          Info
        </Button>
        <Button
          onClick={() => {
            const id = Toaster.loading({ title: "Loading data..." });
            setTimeout(() => Toaster.dismiss(id), 3000);
          }}
        >
          Loading
        </Button>
        <Button
          onClick={() =>
            Toaster.info({
              title: "New version available",
              description: "Reload to update to v2.4.0.",
              closable: true,
            })
          }
        >
          Closable
        </Button>
      </div>
    </div>
  );
}

Closing toasts

Toasts never carry action buttons — use Dialog for interaction; close via closable or Toaster.dismiss(id).

Promise

Toaster.promise shows a loading toast and automatically replaces it with a success or error toast when the promise settles.

"use client";
import { Button, Toaster } from "@/ui";

function deploy(): Promise<string> {
  return new Promise((resolve) => {
    setTimeout(() => {
      resolve("Deployed to production");
    }, 2000);
  });
}

export default function Demo() {
  return (
    <div className="flex flex-col items-center gap-4">
      <Toaster />
      <Button
        onClick={() =>
          Toaster.promise(deploy, {
            loading: "Deploying...",
            success: (message) => message,
            error: () => "Deployment failed, please retry.",
          })
        }
      >
        Start Deploy
      </Button>
    </div>
  );
}

API Reference

High-level Components

Toaster

The toast host — render it once; it carries the imperative methods below.

If multiple <Toaster /> instances are mounted, only the first one renders toasts.

Prop	Type	Default	Description
`visibleToasts`	`number`	`3`	Maximum number of toasts rendered at the same time
`className`	`ClassNameValue`	-	Custom class name for the container
`...props`	`React.ComponentProps<"div">`	-	Remaining props are passed through to the container `section` element

Imperative methods:

Method	Type	Description
`success`	`(options: ToastItemProps) => number`	Shows a success toast, returns the toast id
`error`	`(options: ToastItemProps) => number`	Shows an error toast, returns the toast id
`warning`	`(options: ToastItemProps) => number`	Shows a warning toast, returns the toast id
`info`	`(options: ToastItemProps) => number`	Shows an info toast, returns the toast id
`loading`	`(options: ToastItemProps) => number`	Shows a persistent loading toast (never auto-dismisses)
`dismiss`	`(id?: string \| number) => void`	Dismisses a toast by id; without an id, dismisses all toasts
`promise`	`<T>(promise: () => Promise<T>, data: PromiseData<T>) => void`	Loading toast that upgrades to success/error on settle

ToastItemProps

Options accepted by every imperative method.

Prop	Type	Default	Description
`id`	`string \| number`	-	Toast id; auto-assigned by the store when the toast is created
`title`	`React.ReactNode`	-	Toast title
`description`	`React.ReactNode`	-	Secondary text below the title
`type`	`"success" \| "error" \| "warning" \| "info" \| "loading"`	-	Icon type; set automatically by the semantic methods
`icon`	`React.ReactNode`	type icon	Custom icon, overrides the built-in type icon
`duration`	`number`	`5000`	Auto-dismiss delay in ms; `Infinity` disables auto-dismiss (loading toasts always persist)
`closable`	`boolean`	`false`	Renders a close button in the toast's top-right corner
`onClose`	`(event: CloseEvent) => void`	-	Fired with `type: "auto" \| "manual"` on dismiss start and `type: "complete"` after removal
`classNames`	`{ root?, icon?, content?, title?, description?, close? }`	-	Custom classes for each part of the toast card
`styles`	`{ root?, icon?, content?, title?, description?, close? }`	-	Inline styles for each part of the toast card

CloseEvent

Field	Type	Description
`type`	`"auto" \| "manual" \| "complete"`	Why the toast closed; `"complete"` fires after removal
`id`	`string \| number` (optional)	The toast id

PromiseData<T>

Field	Type	Description
`loading`	`React.ReactNode`	Title shown while the promise is pending
`success`	`React.ReactNode \| ((data: T) => React.ReactNode)`	Title on resolve
`error`	`React.ReactNode \| ((error: unknown) => React.ReactNode)`	Title on reject

Composable Components

ToastRoot

The toast card container. Carries the card surface (border, shadow, background) and the stack/exit animation states driven by data-expanded / data-exiting.
