# Install and place "textarea-002" (Limited Textarea) 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/textarea-002.json

Registry item: https://vibeui.ru/r/textarea-002.json
Installs to: components/vibeui/textarea-002.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 limited textarea that never truncates silently: the counter turns red and the person decides what to cut.

A multiline field with a limit: a character counter, a red border past the limit and a line saying what to do. Zero dependencies, one file.

## 3. How to use it
import { Textarea002 } from "@/components/vibeui/textarea-002"

<Textarea002 limit={180} onChange={setText} />

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-textarea-002-* palette — do not swap it for your theme tokens
- avoiding maxlength: it silently stops accepting input and explains nothing
- the counter with role="status" tied to the field via aria-describedby
- aria-invalid past the limit rather than a red border alone
- vertical resizing
- the line beside the counter: what to do, not only how many are left

## 6. You may change
- limit — the character cap
- label and placeholder
- the onChange handler
- the accent through the accent prop

## 7. Rules
- Blocking submission past the limit is the form's job: the field only shows state.
- Characters are counted, not bytes: database limits often mean the latter.
- A soft limit suits descriptions; strict fields like SMS need another approach.
- 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/textarea-002.json
https://vibeui.ru/r/textarea-002.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-textarea-002-*. Клиентский: "use client". Атрибут maxlength намеренно не используется: он молча запрещает ввод. Превышение выносится в data-over, поле помечается aria-invalid, счётчик объявлен role="status" и связан с полем через aria-describedby.

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 Textarea002Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  label?: string
  placeholder?: string
  limit?: number
  onChange?: (value: string) => void
  accent?: string
}

// Идея компонента: поле с ограничением, которое не обрезает текст молча.
// maxlength не стоит: он не даёт дописать даже пробел и не объясняет, почему
// клавиатура перестала работать. Вместо этого счётчик краснеет, а лишнее
// подсвечивается — человек сам решает, что сократить.
