# Install and place "button-018" (Quantity Stepper) 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-018.json

Registry item: https://vibeui.ru/r/button-018.json
Installs to: components/vibeui/button-018.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 quantity stepper: two buttons around a real input — typing "12" beats pressing plus twelve times.

A quantity stepper: minus, a number input and plus, with the buttons disabled at the range edges and a unit label. Zero dependencies, one file.

## 3. How to use it
import { Button018 } from "@/components/vibeui/button-018"

<Button018 defaultValue={2} min={1} max={20} onChange={setQty} />

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-018-* palette — do not swap it for your theme tokens
- the real input in the middle: twenty plus presses is not a workflow
- disabling the buttons at the edges instead of silently doing nothing
- the aria-label carrying the next value: a bare "minus" tells a screen reader nothing
- tabular figures so the field does not jitter
- hiding the native number spinners: custom buttons already sit beside them

## 6. You may change
- defaultValue, min, max and step
- label — the field's name
- unit — the measurement unit
- the onChange handler

## 7. Rules
- The value is clamped on every input: an empty field becomes the minimum.
- A stepper is wrong for large numbers: hundreds want a plain field.
- Removing an item from a cart is not "minus to zero": give it its own action.
- 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-018.json
https://vibeui.ru/r/button-018.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-button-018-*. Клиентский: "use client". Значение живёт в input type="number" со скрытой подписью через useId; стрелки браузера убраны, потому что рядом стоят собственные кнопки. На границах диапазона кнопки disabled, а их aria-label содержит будущее значение.

Component source

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

"use client"

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

export type Button018Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange" | "defaultValue"
> & {
  defaultValue?: number
  min?: number
  max?: number
  step?: number
  label?: string
  unit?: string
  onChange?: (value: number) => void
}

// Идея компонента: пара кнопок вокруг числа. Само число — поле ввода, а не
// текст: набрать «12» быстрее, чем нажать плюс двенадцать раз. Кнопки
// гаснут на границах диапазона, а не молча ничего не делают, и у каждой своё
// имя со значением — «минус» без контекста скринридеру бесполезен.
