Buttons

Notification Badge

A counter over the corner of the button: the number lands in both the badge and the aria-label, large values collapse into 99+, and zero removes the badge entirely.

# Install and place "button-030" (Notification Badge) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/button-030.json

Registry item: https://vibeui.ru/r/button-030.json
Installs to: components/vibeui/button-030.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A counter over the corner of the button: the number lands in both the badge and the aria-label, large values collapse into 99+, and zero removes the badge entirely.

An icon button with an unread counter in its corner. The number is visible in the badge and audible in the aria-label, so 12 unread is not only a picture. Values above the cap collapse into 99+, zero removes the badge along with its halo, and a ring in the surface colour keeps the digit off the bell beneath it.

## 3. How to use it
import { Button030 } from "@/components/vibeui/button-030"

<Button030 label="Notifications" count={12} onClick={openInbox} />

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the number in both the badge and the aria-label: a counter that is never spoken does not exist for a screen reader
- the ring in the surface colour around the badge — without it the digit melts into the glyph below
- collapsing large values into 99+: otherwise the badge stretches the button and breaks the row
- the badge disappearing at zero rather than showing a zero — an empty counter is no counter
- tabular-nums on the digits so the badge keeps its width across values
- the prefers-reduced-motion rule, which removes the pulsing halo completely

## 6. You may change
- the button name through the label prop, which goes into the aria-label with the number
- the value through the count prop, computed by your app
- the collapse threshold through the cap prop
- the badge colour through the badge prop
- outer spacing through className

## 7. Rules
- The component polls nothing: count arrives from outside, there is no timer and no request inside.
- Do not leave the pulse on a counter that is always present: it is meant for something genuinely new, not for background.
- The aria-label phrase is written in Russian in the code — translate it along with the rest of the interface.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/button-030.json
https://vibeui.ru/r/button-030.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-button-030-*. Серверный: число приходит пропом count, компонент ничего не считает сам. Бейдж обведён кольцом цвета подложки через box-shadow, поэтому не сливается с колокольчиком. Порог схлопывания задаётся пропом cap. Ореол — CSS-анимация, которая полностью выключается при prefers-reduced-motion.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Button030Props = Omit<
  ComponentPropsWithoutRef<"button">,
  "children"
> & {
  label?: string
  /** Сколько непрочитанного. Ноль прячет бейдж целиком. */
  count?: number
  /** С какого числа показывать «99+». */
  cap?: number
  badge?: string
}

// Идея компонента: счётчик поверх угла кнопки. Число попадает и в бейдж, и в
// aria-label, поэтому «12 непрочитанных» слышно, а не только видно. Бейдж
// обведён кольцом цвета подложки — иначе цифра на границе значка теряется, —
// а большие числа схлопываются в «99+», чтобы кнопка не растягивалась.
