# Date Range Picker (Notchset): prompt.md (v1.0.0)

- id: `date-range-picker` · version 1.0.0 · component · pro (Pro)
- category: Inputs
- build: Base UI (this item also ships a Radix build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/date-range-picker`
- npm dependencies: @base-ui/react@^1
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/date-range-picker
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A range picker for dashboards: the range and its length rolling in the trigger, grouped presets on a rail, a range grid whose fill ripples from the start, typed FROM and TO dates, and APPLY.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `@base-ui/react@^1` (Base UI build); `radix-ui@^1` (Radix build).
- Files: `components/ui/notchset/date-range-picker.tsx`; shared code: `lib/beautiful-ui/notchset/date-range.tsx`, `lib/beautiful-ui/notchset/calendar.tsx`, `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: separate Base UI and Radix files. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `DateRangePicker`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { DateRangePicker, type DateRangeValue, type RangePresetGroup } from "@/components/ui/notchset/date-range-picker";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `DateRangePicker` | `date-range-picker-trigger` | The trigger. |
| `—` | `date-range-picker-content` | The popup. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/date-range-picker.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- date range picker, range, period, dashboard filter, last 30 days, analytics range, Notchset
- The period a dashboard or report covers

### Not when
- One date: use Date Picker

## Mistakes
- The popup is 520px wide: give the trigger room at the end of a header

## Usage

```tsx
"use client";

import * as React from "react";
import { DateRangePicker, type DateRangeValue, type RangePresetGroup } from "@/components/ui/notchset/date-range-picker";

const DAY = 864e5;
const today = new Date(new Date().setHours(0, 0, 0, 0));
const yesterday = new Date(today.getTime() - DAY);
const presets: RangePresetGroup[] = [
  {
    group: "RECENT",
    items: [
      { label: "Last 7 days", from: new Date(today.getTime() - 7 * DAY), to: yesterday },
      { label: "Last 30 days", from: new Date(today.getTime() - 30 * DAY), to: yesterday },
    ],
  },
];

export function ReportRange() {
  const [range, setRange] = React.useState<DateRangeValue>({ from: presets[0]!.items[0]!.from, to: yesterday });
  return <DateRangePicker value={range} onValueChange={setRange} presets={presets} max={yesterday} />;
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `value / onValueChange` | `{ from: Date, to: Date }` |  | Changes only on APPLY or a preset. |
| `presets` | `{ group, items: { label, meta?, from, to }[] }[]` |  | The rail. |
| `min / max` | `Date` |  | The pickable span. |
| `customLabel` | `string` |  | The rail's last row (clears and focuses FROM). |
| `events` | `Record<YYYY-MM-DD, string[]>` |  | Dots under days. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| ← → ↑ ↓ | Day / week |
| PgUp / PgDn | Month |
| Enter | Pick an end; in TO, apply |
| Esc | Close |

## Performance

- The popup mounts only while open; the draft lives in it.

## Responsive

- The popup caps at the viewport width less 16px.

## Motion inventory

| Interaction | What moves |
|---|---|
| Open | The leader drops and the popup unrolls (380ms after 80ms) |
| Range | The fill ripples out from the start, 10ms a day (up to 320ms) |
| Preset | The grid fills, then it commits and closes 320ms later |
| Apply | The trigger's digits roll, ones first |

## Accessibility contract (preserve when editing)
- The Base UI or Radix popover; presets are toggle buttons in labelled groups
- The typed fields say their format; a bad date is flagged (aria-invalid) and dropped

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/date-range-picker
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
