Usage

tsx

"use client";

import { TriageDeck } from "mizu-ui";

export function Example() {
  return (
    <TriageDeck
      label="Inbox"
      items={[
        { id: "a", title: "Invoice from Northworks" },
        { id: "b", title: "Team offsite dates" },
      ]}
      itemLabel={(m) => m.title}
      decisions={[
        { id: "archive", label: "Archive", direction: "left" },
        { id: "keep", label: "Keep", direction: "right", tone: "success" },
      ]}
      renderItem={(m) => <h3 style={{ margin: 0, fontSize: 24 }}>{m.title}</h3>}
    />
  );
}

It starts with "use client" because it keeps state or passes functions to components, so it pastes into a Next.js page as it is. Other React setups ignore the directive.

Source & setup

Add this component to your project with the shadcn CLI. The command copies its source into your configured UI directory, with base.css, Mizu’s tokens, and the stylesheets that hold its rules. Each rule lives in one stylesheet, so components you add together never repeat CSS. In a project without a components.json, run npx shadcn@latest init 0xuser64bit/mizu/preset first: plain init installs shadcn’s theme into your global CSS. Then load the fonts.

sh

npx shadcn@latest add 0xuser64bit/mizu/triage-deck

Every component imports from its own path, its name in kebab case. To paste the example, replace its mizu-ui import with:

tsx

import { TriageDeck } from "@/components/ui/mizu/triage-deck";

For npm imports, import mizu-ui/styles.css once. Fonts are optional via mizu-ui/fonts.css. Override --mizu-* tokens or use className for local styling. Requires React and Motion. A Client Component: its source starts with “use client”.

Props

Prop	Type	Default	Description
label / items / renderItem	string / T[] / (item) => ReactNode	—	Region name, the queue (each with an id) and a card body.
itemLabel	(item) => string	—	A short name used in announcements and the deck's label.
decisions	TriageDecision[]	—	id, label, direction (left, right or up — one each) and tone.
onDecide / onUndo	(item, decision) => void	—	Record or reverse a decision.
empty	ReactNode	—	Shown when every item has been decided.

Accessibility

The deck is a focusable group named after the current item and its position. Arrow keys make the decisions a fling would; every decision also has a labelled button with its key, and Backspace undoes. Each decision announces what happened and what comes next. Tallies are a labelled list.

Motion

The top card follows your hand and tilts with it; decision stamps fade in as you cross a threshold, and release velocity carries it off. The next card steps forward in depth, and an undone card flies back from the side it left by. Reduced motion decides without flight or tilt.
