# Install and place "command-010" (Loading Results) 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/command-010.json

Registry item: https://vibeui.ru/r/command-010.json
Installs to: components/vibeui/command-010.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 palette backed by server search: while the answer is in flight it shows skeleton rows of the same height plus a bar under the field, never an empty list.

A palette with a loading state: a bar under the field, skeleton rows instead of an empty list and a status line in the footer. Zero dependencies, one file.

## 3. How to use it
import { Command010 } from "@/components/vibeui/command-010"

<Command010 items={["Open the component catalog"]} delay={600} />

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-command-010-* palette — do not swap it for your theme tokens
- skeletons instead of an empty list: "nothing found" and "not here yet" mean different things
- matching skeleton and row heights — otherwise the list jumps when the answer lands
- aria-busy on the field and role=status in the footer: loading must be announced, not merely drawn
- disabling the arrows while loading: the highlight must not point at rows about to vanish
- the prefers-reduced-motion rule — an endless progress bar is especially intrusive

## 6. You may change
- the items array
- the response latency through the delay prop
- the field hint through the placeholder prop
- the number of skeletons and the accent through the accent prop

## 7. Rules
- The timer stands in for a request: replace it with your fetch and cancel stale answers.
- The skeletons are aria-hidden: announcing them is pointless, the footer carries the status.
- Even with delay set to zero a flash is possible — show the loading state after a short grace period.
- 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/command-010.json
https://vibeui.ru/r/command-010.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-command-010-*. Клиентский: "use client" ради useState и useEffect. Признак загрузки включается в обработчике ввода, а эффект только ждёт ответ по таймеру и перезапускается при смене запроса — так же ведёт себя обычный debounce вокруг настоящего запроса. Загрузка показана двумя способами: бегунок в полосе под полем и скелетоны строк той же высоты, поэтому после ответа список не прыгает. Поле несёт aria-busy, подвал — role=status, а стрелки во время загрузки заблокированы, чтобы подсветка не указывала на исчезающие строки.

Component source

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

"use client"

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

export type Command010Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children"
> & {
  items?: string[]
  delay?: number
  placeholder?: string
  accent?: string
}

// Идея компонента: палитра, которая ищет на сервере. Между вводом и ответом
// проходит время, и подменять его пустым списком нельзя — «ничего не найдено»
// и «ещё не приехало» выглядят одинаково, но означают разное. Пока запрос в
// работе, показываются скелетоны той же высоты, что и строки, поэтому список
// не прыгает; полоса под полем и role=status озвучивают загрузку.
