# Install and place "tabbar-001" (Mobile Tab 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/tabbar-001.json
Registry item: https://vibeui.ru/r/tabbar-001.json
Installs to: components/vibeui/tabbar-001.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 mobile bottom tab bar: the height accounts for the safe area, and the active item is marked by a dot, not colour alone.
A bottom navigation bar: four labelled items, a counter badge and a dot on the active one. Zero dependencies, one file, no client JS.
## 3. How to use it
import { Tabbar001 } from "@/components/vibeui/tabbar-001"
<Tabbar001 items={[{ label: "Catalog" }, { label: "Orders", count: 3 }]} activeLabel="Catalog" />
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-tabbar-001-* palette — do not swap it for your theme tokens
- env(safe-area-inset-bottom): without it the bottom item hides under the system bar
- the dot on the active item — colour alone fails in sunlight
- aria-current="page" on the active link
- the badge number in the link's aria-label: the badge itself is hidden from screen readers
- labels under the glyphs: wordless icons get guessed wrong
## 6. You may change
- the items array and their URLs
- activeLabel — the current section
- the accent through the accent prop
- the glyph shapes
## 7. Rules
- Do not go past five items: the labels stop fitting on a narrow screen.
- The bar is meant for phones: on desktop use side navigation.
- Glyphs are drawn with borders rather than an icon set: swap in your own, keeping the size.
- 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/tabbar-001.jsonhttps://vibeui.ru/r/tabbar-001.jsonКомпонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-tabbar-001-*. Серверный: хуков нет. Нижний отступ берётся из env(safe-area-inset-bottom), иначе на iPhone пункт уходит под системную полосу. Значок со счётчиком спрятан от скринридера, а число попадает в aria-label ссылки.
Component source
The same file your agent installs. Here in case you would rather copy it by hand.

// Идея компонента: нижняя панель навигации для телефона. Высота панели
// считается вместе с safe-area-inset-bottom, иначе на iPhone нижний пункт
// попадает под системную полосу. Активный пункт отмечен цветом и точкой
// сверху: одного цвета мало, когда экран на солнце.
