Buttons

File Download Link

A download link that names the weight and the format before the click: an extension chip, the file name and the size beside it. A real <a download>, not a button.

  1. 1. Copy the link.
  2. 2. Write to your agent in your own words and drop the link into the sentence.
  3. 3. The agent opens the link and installs the component from the registry.

# Install and place "button-026" (File Download Link) 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/button-026.json

Registry item: https://vibeui.ru/r/button-026.json
Installs to: components/vibeui/button-026.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 download link that names the weight and the format before the click: an extension chip, the file name and the size beside it. A real <a download>, not a button.

A download link shaped like a button, with the file described on it. On the left an extension chip recoloured per format, in the middle the name, under it the format and the weight — the pair people use to decide between now and later. The arrow dips a couple of pixels on hover. This is a real link with download, not a button with a handler.

## 3. How to use it
import { Button026 } from "@/components/vibeui/button-026"

<Button026
  href="/files/report-march.pdf"
  fileName="report-march.pdf"
  label="March report"
  size="2.4 MB"
/>

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 <a> tag with the download attribute instead of a button: otherwise middle-click, save-as and copying the address are all lost
- the weight and the format next to the name — that is the reason this component exists
- the extension chip and its recolouring through data-format: the format registers before the name is read
- the single-line ellipsis on a long name — the card has to keep one height
- the aria-label carrying name, format and weight: the meta line is aria-hidden so nothing is announced twice
- tabular-nums on the weight, otherwise the digits dance as the value changes

## 6. You may change
- the caption through the label prop
- the address through href and the file name through fileName, which drives the format chip
- the weight through the size prop: the server computes it, the component only prints the string
- the accent colour through the accent prop
- the card width through className, the built-in maximum is 20rem

## 7. Rules
- The download attribute is ignored for cross-origin files: the browser simply opens them. Serve external files through your own domain.
- Do not put unknown into size: with no weight it is better to drop the line than to lie about it.
- Do not turn the link into a button with a programmatic download — that throws away everything the <a> tag was taken for.
- 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/button-026.json
https://vibeui.ru/r/button-026.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-button-026-*. Серверный: хуков нет. Корень — тег <a> с атрибутом download, поэтому работают средняя кнопка мыши, «сохранить как» и копирование адреса. Формат вычисляется из расширения fileName и уходит в data-format, который перекрашивает плашку. Размер приходит строкой: считать вес файла — работа сервера.

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 Button026Props = Omit<
  ComponentPropsWithoutRef<"a">,
  "children" | "download"
> & {
  label?: string
  /** Имя файла: из него берутся значок формата и атрибут download. */
  fileName?: string
  /** Размер строкой — его считает сервер, а не кнопка. */
  size?: string
  accent?: string
}

// Идея компонента: перед скачиванием человек хочет знать, что именно
// прилетит. Это настоящая ссылка с атрибутом download, а не button: работают
// средняя кнопка мыши, «сохранить как» и копирование адреса. Формат берётся
// из расширения имени файла и рисуется плашкой, вес стоит рядом — по этой
// паре решают, качать ли сейчас или с вайфая.
