# Install and place "badge-023" (Truncating Badge) 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/badge-023.json
Registry item: https://vibeui.ru/r/badge-023.json
Installs to: components/vibeui/badge-023.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 badge for text of unpredictable length: end truncation is left to CSS, middle truncation to code, and the full text stays available.
A badge that truncates long text in two modes: from the end via CSS and in the middle via code. Zero dependencies, one file, no client JS.
## 3. How to use it
import { Badge023 } from "@/components/vibeui/badge-023"
<Badge023 width={16} truncate="middle">
feature/registry-badge-overflow
</Badge023>
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-badge-023-* palette — do not swap it for your theme tokens
- the full text in title and in the hidden caption: truncation must not lose the content
- the ellipsis on the inner node rather than the flex container — otherwise the string is cut with no mark
- middle truncation for names with a shared prefix: "feature/very-long-…" is indistinguishable from a dozen neighbours
- the monospace font: it makes a width in ch predictable
- the badge's own light surface: without it the dark text disappears on a dark background
## 6. You may change
- the width in characters through width
- the truncation mode through truncate
- the text through children
- the badge radius and height in the block rules
## 7. Rules
- children is typed as a string: middle truncation works on text, not on a node tree.
- The ch unit measures the width of a zero — in a proportional font the real string is wider, which is why middle mode keeps four characters of slack.
- title is not shown on touch screens: if the text is critical, repeat it next to the badge.
- 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/badge-023.jsonhttps://vibeui.ru/r/badge-023.jsonОдин файл, ноль зависимостей, палитра в локальных переменных --vibeui-badge-023-*. Серверный: хуков нет. Ширина задаётся в ch и кладётся в --vibeui-badge-023-width инлайновым стилем. Режим end работает штатным text-overflow:ellipsis, причём многоточие живёт на внутреннем узле: у flex-контейнера text-overflow не срабатывает и строка просто отрезалась бы без знака. Режим middle CSS не умеет вовсе, поэтому строку режет функция shorten — голова и хвост считаются от лимита, между ними многоточие; у имени ветки и у пути к файлу значимы оба края. Полный текст уходит в title и в скрытую подпись, а обрезанный вариант помечается aria-hidden.
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 Badge023Props = Omit<
ComponentPropsWithoutRef<"span">,
"children"
> & {
children?: string
width?: number
truncate?: "end" | "middle"
}
// Идея компонента: плашка для текста, длину которого никто не гарантирует —
// имени ветки, названия файла, адреса. Два режима обрезки: с конца отрезает
// CSS, а по середине — код, потому что у ветки и у файла значимы оба края,
// и «feature/very-long-…» неотличимо от десятка соседей. Полный текст в
// title и в доступном имени: обрезка не должна терять содержание.
