Installation

npx logic2b@latest add alert-dialog

Working with an AI assistant? Copy this prompt into Claude Code, Cursor or Copilot — it carries the install steps, a no-CLI fallback and a verification checklist.

Add the "alert-dialog" item from the logic2b ui registry (https://ui.logic2b.com) to this project. Follow every step and verify at the end.

## Steps

1. If the project has no `components.json` yet, set up logic2b ui first:

   ```bash
   npx logic2b@latest init
   ```

2. Install the item (the CLI resolves registry dependencies automatically):

   ```bash
   npx logic2b@latest add alert-dialog
   ```

3. Install any npm dependencies the command prints.

## If the CLI is not available

Do it manually from the registry payload:

1. Fetch https://ui.logic2b.com/r/alert-dialog.json.
2. Write every entry in `files[]` to its mapped project path (see below).
3. Repeat (recursively) for each name in `registryDependencies`.
4. Install every package listed in `dependencies` across those payloads.

## Registry reference

- Index of every item: https://ui.logic2b.com/r/index.json
- Item payload (full source): https://ui.logic2b.com/r/<name>.json
- Usage examples per item: https://ui.logic2b.com/r/demos/index.json → https://ui.logic2b.com/r/demos/<demo>.json
- Docs index for agents: https://ui.logic2b.com/llms.txt (full docs: https://ui.logic2b.com/llms-full.txt)
- Every docs page is Markdown when you append `.md` to its URL.

Registry file paths map to project paths like this:
- `ui/*` → `@/components/ui/*`
- `blocks/<name>/*` → `@/components/*`
- `charts/*` → `@/components/charts/*`
- `hooks/*` → `@/hooks/*`
- `lib/utils.ts` → `@/lib/utils.ts`
- `theme.css` → next to the project's Tailwind entry stylesheet

## Conventions (do not break these)

- Tailwind CSS v4 (CSS-first config; no tailwind.config.js needed) and React 19.
- All colors go through semantic tokens (`bg-primary`, `text-muted-foreground`,
  `border-border`, …). Never hardcode hex/oklch values in components.
- Dark mode is class-based: toggle `.dark` on `<html>`.
- Icons come from lucide-react.

## Verify before finishing

1. The dev server starts and the app renders without console errors.
2. TypeScript compiles (`tsc --noEmit` or the framework's check).
3. Components use the theme: a `<Button>` shows the primary token color,
   and toggling `.dark` on `<html>` switches the palette.

Install the dependencies:

npm install radix-ui

Copy into ui/alert-dialog.tsx:

API

Prop	Type	Default
`open` / `defaultOpen` (AlertDialog)	`boolean` — controlled/uncontrolled open state	—
`onOpenChange` (AlertDialog)	`(open: boolean) => void`	—
`asChild` (AlertDialogTrigger / Action / Cancel)	`boolean`	`false`

AlertDialogAction and AlertDialogCancel render with the default and outline button variants respectively — pass className to restyle (e.g. a destructive action).

Examples

Destructive action

Style the confirm button as destructive for irreversible operations.

import {
  AlertDialog,
  AlertDialogAction,
  AlertDialogCancel,
  AlertDialogContent,
  AlertDialogDescription,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogTitle,
  AlertDialogTrigger,
} from "@/components/ui/alert-dialog"
import { Button, buttonVariants } from "@/components/ui/button"

export default function AlertDialogDestructiveDemo() {
  return (
    <AlertDialog>
      <AlertDialogTrigger asChild>
        <Button variant="destructive">Discard changes</Button>
      </AlertDialogTrigger>
      <AlertDialogContent>
        <AlertDialogHeader>
          <AlertDialogTitle>Discard unsaved changes?</AlertDialogTitle>
          <AlertDialogDescription>
            Your edits will be lost. This action cannot be undone.
          </AlertDialogDescription>
        </AlertDialogHeader>
        <AlertDialogFooter>
          <AlertDialogCancel>Keep editing</AlertDialogCancel>
          <AlertDialogAction className={buttonVariants({ variant: "destructive" })}>
            Discard
          </AlertDialogAction>
        </AlertDialogFooter>
      </AlertDialogContent>
    </AlertDialog>
  )
}

Controlled

Open the dialog from your own state with open and onOpenChange.

import * as React from "react"

import {
  AlertDialog,
  AlertDialogAction,
  AlertDialogCancel,
  AlertDialogContent,
  AlertDialogDescription,
  AlertDialogFooter,
  AlertDialogHeader,
  AlertDialogTitle,
} from "@/components/ui/alert-dialog"
import { Button } from "@/components/ui/button"

export default function AlertDialogControlledDemo() {
  const [open, setOpen] = React.useState(false)

  return (
    <div className="flex flex-col items-center gap-4">
      <Button variant="outline" onClick={() => setOpen(true)}>
        Open dialog
      </Button>
      <AlertDialog open={open} onOpenChange={setOpen}>
        <AlertDialogContent>
          <AlertDialogHeader>
            <AlertDialogTitle>Confirm subscription</AlertDialogTitle>
            <AlertDialogDescription>
              You will be charged $9 per month until you cancel.
            </AlertDialogDescription>
          </AlertDialogHeader>
          <AlertDialogFooter>
            <AlertDialogCancel>Cancel</AlertDialogCancel>
            <AlertDialogAction>Subscribe</AlertDialogAction>
          </AlertDialogFooter>
        </AlertDialogContent>
      </AlertDialog>
    </div>
  )
}

Accessibility

Follows the WAI-ARIA Alert Dialog pattern and traps focus while open.
Opening moves focus to the dialog; closing returns it to the trigger.
Escape closes the dialog and fires AlertDialogCancel. Unlike a plain dialog, clicking the overlay does not dismiss it — a response is required.
The content is labelled by AlertDialogTitle and described by AlertDialogDescription.
