NextToast

NextToast is a lightweight, flexible toast notification system for React and Next.js. It is designed to be simple to use, fully customizable, and safe for client components.

It supports standard notifications, loading states, confirmations, promises, and fully custom React components.

Features

• Works with Next.js App Router and React
• Simple global API (toast.success, toast.error, etc.)
• Rich or plain styling modes
• Confirmation toasts with actions
• Promise-based toasts
• Supports ReactNode everywhere (not just strings)
• Configurable close button behavior
• Automatic stacking and dismissal
• Accessible (ARIA roles included)
• No external dependencies

Installation

Copy the source files into your project or install from your package source.

Basic Usage

Mount the toast container once in your app layout:

import { NextToast } from "./next-toast";

export default function RootLayout({ children }) {
  return (
    <>
      {children}
      <NextToast />
    </>
  );
}

Trigger a toast from anywhere:

import { toast } from "./toast-store";

toast.success("Saved successfully");
toast.error("Something went wrong");
toast.info("New update available");

Toast Types

Supported types:

• success
• error
• info
• loading
• default
• custom

Rich vs Plain Mode

You can control visual style using the richColors prop.

<NextToast richColors={true} />

• richColors={false} → white background, black border, black text
• richColors={true} → semantic colors (success, error, info, loading)

Close Button Control

Global control:

<NextToast position="top-right" richColors={false} closeButton={true} />

Per-toast control:

toast.info("Closable toast", { dismissible: true });

A toast will show the close button only if:

• closeButton is enabled on <NextToast />
• dismissible is true for that toast

Confirmation Toasts

Confirmation toasts support React components, not just strings.

toast.confirm(
  <div>
    <strong>Delete item?</strong>
    <div>This action cannot be undone.</div>
  </div>,
  () => {
    console.log("Confirmed");
  },
  {
    label: "Delete",
    cancelLabel: "Cancel",
    dismissible: true,
  }
);

Confirmation Options

| Option | Type | Description | | ------------- | --------- | ---------------------- | | label | ReactNode | Confirm button content | | cancelLabel | ReactNode | Cancel button content | | dismissible | boolean | Enables close button | | duration | number | Auto dismiss time |

Promise Toasts

Handle async flows easily:

toast.promise(
  fetch("/api/save"),
  {
    loading: "Saving...",
    success: "Saved",
    error: "Failed",
  }
);

The toast updates automatically based on promise state.

Custom Toasts

Render anything you want:

toast.custom((t) => (
  <div>
    <h4>Custom Content</h4>
    <button onClick={() => toast.dismiss(t.id)}>Close</button>
  </div>
));

Configuration Props

<NextToast />

| Prop | Type | Default | | ------------- | ------- | ------------ | | position | string | top-center | | richColors | boolean | true | | closeButton | boolean | true | | maxVisible | number | 4 |

Accessibility

• Uses proper ARIA roles
• Error toasts use role="alert"
• Screen-reader friendly
• Keyboard accessible close button
