Code Block
Listing Outline
A long listing you can walk through: the outline of declarations on the left, scrollable code on the right, and the target row highlighted through :target.

- 1. Copy the link.
- 2. Write to your agent in your own words and drop the link into the sentence.
- 3. The agent opens the link and installs the component from the registry.
put this in the header: https://vibeui.ru/c/codeblock-019?lang=en
import { db } from '@/lib/db'export async function addToCart(id: string) { await db.cart.add(id)}export async function removeFromCart(id: string) { await db.cart.remove(id)}export async function clearCart() { await db.cart.clear()}export const CART_LIMIT = 50Show the full instructions
What the link says, spelled out. Use it when your agent cannot open links — paste this text instead.
# Install and place "codeblock-019" (Listing Outline) 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/codeblock-019.json
Registry item: https://vibeui.ru/r/codeblock-019.json
Installs to: components/vibeui/codeblock-019.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 long listing you can walk through: the outline of declarations on the left, scrollable code on the right, and the target row highlighted through :target.
A listing with an outline of declarations and anchor navigation: the target row lights up through :target. Zero dependencies, no client JS.
## 3. How to use it
import { Codeblock019 } from "@/components/vibeui/codeblock-019"
<Codeblock019
path="app/actions.ts"
maxHeight={14}
idPrefix="actions"
/>
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-codeblock-019-* palette — do not swap it for your theme tokens
- a unique idPrefix per block: identical ids wire the anchors of two listings together
- :target as the source of the highlight — state in the address gives a shareable link to a line
- tabIndex and role=region on the scroller: without them the code cannot be scrolled by keyboard
- scroll-margin on the rows: without it the target sits flush to the edge and reads as clipped
- the layout rules on the inner shell: a container query never applies to the container itself
## 6. You may change
- the listing rows through the lines array and the outline through the outline array
- the file path through path
- the height of the scroll area through maxHeight
- the anchor prefix through idPrefix
## 7. Rules
- Following an anchor changes the page address — the price of a shareable link to a line.
- prefers-reduced-motion drops the smooth scroll: the jump becomes instant, which is right.
- The outline is written by hand and can drift from the code: it never checks the line numbers.
- 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/codeblock-019.jsonhttps://vibeui.ru/r/codeblock-019.jsonКомпонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-codeblock-019-*. Серверный: переходы — обычные якоря, состояние живёт в адресе страницы, поэтому ссылкой на строку можно поделиться. У строк есть id с префиксом из пропса idPrefix: два блока на странице с одинаковым префиксом сцепили бы якоря. Область кода прокручивается сама и получает tabIndex с role=region, иначе до неё не добраться с клавиатуры; scroll-margin отодвигает строку-цель от края. Раскладка считается от собственной ширины и лежит на внутреннем [data-part="shell"].
Component source
The same file your agent installs. Here in case you would rather copy it by hand.
import type { CSSProperties } from "react"
export type Codeblock019Mark = {

export type Codeblock019Props = {

// Идея компонента: длинный файл, по которому можно ходить. Слева оглавление
// объявлений, справа прокручиваемый листинг; переходы — обычные якоря, поэтому
// работают без JS, а строка-цель подсвечивается через :target.
