# Install and place "button-019" (Reaction Button) 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-019.json

Registry item: https://vibeui.ru/r/button-019.json
Installs to: components/vibeui/button-019.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 reaction button with a counter: state lives in aria-pressed, not in a label that flips to "Unlike".

A reaction button: heart, label and counter, state in aria-pressed, the number updating instantly. Zero dependencies, one file.

## 3. How to use it
import { Button019 } from "@/components/vibeui/button-019"

<Button019 label="Like" count={128} onChange={send} />

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 local --vibeui-button-019-* palette — do not swap it for your theme tokens
- aria-pressed instead of flipping the label: "Unlike" reads as a different action
- the heart growing denser and larger when pressed — colour is not the only cue
- the instant counter update: a reaction is cheap, waiting on the server is not worth it
- the aria-label carrying the count: a bare number is lost in speech
- tabular figures on the counter

## 6. You may change
- label and the starting count
- defaultPressed — the state on load
- the onChange handler
- the accent through the accent prop

## 7. Rules
- The number updates client-side: reconcile with the server on the next load.
- If the server rejects the reaction, the state must be rolled back — the component does not know.
- Reactions without a counter read calmer: a number turns them into a contest.
- 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

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-button-019-*. Клиентский: "use client". Нажатое состояние — aria-pressed, и по нему же идёт стилизация. Счётчик пересчитывается на клиенте сразу, поэтому отклик мгновенный. Сердце собрано из двух повёрнутых фигур и заливается в нажатом состоянии — цвет не единственный признак.

Component source

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

"use client"

import { useState } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Button019Props = Omit<
  ComponentPropsWithoutRef<"button">,
  "children" | "onChange"
> & {
  label?: string
  count?: number
  defaultPressed?: boolean
  onChange?: (pressed: boolean) => void
  accent?: string
}

// Идея компонента: кнопка-реакция со счётчиком. Состояние объявлено через
// aria-pressed, а не сменой подписи: «Нравится» → «Не нравится» звучит как
// другое действие, а не как отмена. Счётчик меняется сразу, не дожидаясь
// ответа сервера: реакция — дешёвое действие, и ждать её незачем.
