# Install and place "spinner-003" (Indeterminate Progress Bar) 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/spinner-003.json

Registry item: https://vibeui.ru/r/spinner-003.json
Installs to: components/vibeui/spinner-003.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
An indeterminate progress bar with no aria-valuenow: the moment that attribute appears, a screen reader announces a percentage nobody calculated.

An indeterminate progress bar: the beam runs on transform and role=progressbar carries no invented percentage. Zero dependencies, one file, no client JS.

## 3. How to use it
import { Spinner003 } from "@/components/vibeui/spinner-003"

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-spinner-003-* palette — do not swap it for your theme tokens
- the absence of aria-valuenow: with it a screen reader announces a percentage nobody calculated
- the transform-based animation — animating width recalculates layout on every frame
- overflow:hidden on the track, otherwise the beam escapes past its edges
- the caption above the bar: a bar without words never says what is syncing
- the component's own light surface: the captions are dark and vanish on a dark catalog background

## 6. You may change
- the caption and the second line through label and hint
- the bar thickness through height in pixels
- the beam colour through the --vibeui-spinner-003-accent variable
- the block width through max-width

## 7. Rules
- Once the share is known, replace this with a determinate progress bar showing a percentage.
- A thickness below 3px is hard to see on unscaled displays.
- aria-busy sits on the track: lift it to the container when a whole section is blocked.
- 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/spinner-003.json

https://vibeui.ru/r/spinner-003.json

Серверный компонент, хуков нет. Дорожка помечена role=progressbar с aria-busy и без aria-valuenow — это и есть корректное объявление неопределённого прогресса; выдуманный процент хуже его отсутствия. Отрезок ездит по дорожке анимацией transform, а не изменением left или width: браузер не пересчитывает раскладку на каждом кадре, и полоса не греет процессор в длинном списке. Толщина вынесена в проп height и подставляется переменной в пикселях. При prefers-reduced-motion отрезок занимает дорожку целиком и медленно дышит. Подложка светлая: подписи тёмные.

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 Spinner003Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children"
> & {
  label?: string
  hint?: string
  height?: number
}

// Идея компонента: полоса неопределённого прогресса. У неё нет aria-valuenow —
// и это принципиально: как только атрибут появляется, скринридер называет
// процент, которого никто не считал. Отрезок ходит по дорожке анимацией
// transform, а не изменением left: браузер не пересчитывает раскладку на
// каждом кадре. При запрете движения отрезок занимает дорожку целиком и
// пульсирует — «работа идёт» остаётся, бег исчезает.
