# State bar (Notchset): prompt.md (v2.1.0) - id: `state-bar` · version 2.1.0 · component · free - category: Charts - build: one set of files for every shadcn style - install: `npx shadcn@latest add https://notchset.dev/r/state-bar.json` - npm dependencies: none - registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json - docs: https://notchset.dev/components/state-bar - The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand. Where things sit right now, as one stacked bar: each state of work in its own colour, at the same strengths a cumulative flow's bands use, and a key under it that writes every state's count, a zero included. With onSelect, each key opens the records it counts.. ## Build it - Stack: React 18.3 or 19, TypeScript, Tailwind CSS v4 utility classes on the foundation's roles, a components.json (imports use its aliases). - Packages: none beyond React. - Files: `components/ui/notchset/state-bar.tsx`. - Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`. - Builds: one set of files, the same for every shadcn style. - Exports to keep: `StateBar`, and every exported type. - CSS: the install adds the notchset foundation (its roles, keyframes and motion switch, reading your shadcn tokens for colour) 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. - Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component. - This item reads `--ns-ease`, `--ns-ink`, `--ns-ink-2`, `--ns-line-soft`, `--ns-panel`, `--ns-signal`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-text-small`, `--ns-weight-medium`. - Retune it (on any ancestor) with the foundation's roles and hooks: `--ns-bad`, `--ns-bad-ink`, `--ns-band`, `--ns-band-edge`, `--ns-band-grade`, `--ns-band-optimal`, `--ns-beat`, `--ns-bezel`, `--ns-canvas`, `--ns-cat-1`, `--ns-cat-2`, `--ns-cat-3`, `--ns-cat-4`, `--ns-cat-5`, `--ns-cat-6`, `--ns-check`, `--ns-chip`, `--ns-control`, `--ns-control-pad`, `--ns-control-sm`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-dialog`, `--ns-dialog-lg`, `--ns-dialog-sm`, `--ns-ease`, `--ns-ease-in`, `--ns-ease-panel`, `--ns-ease-pop`, `--ns-field`, `--ns-flood-arc`, `--ns-flood-aurora`, `--ns-flood-behind-1`, `--ns-flood-behind-2`, `--ns-flood-bloom`, `--ns-flood-deep`, `--ns-flood-dial-bloom`, `--ns-flood-glass`, `--ns-flood-grain`, `--ns-flood-image`, `--ns-flood-ink`, `--ns-flood-ink-low`, `--ns-flood-light`, `--ns-flood-mid`, `--ns-flood-pale`, `--ns-flood-pane`, `--ns-flood-pane-edge`, `--ns-flood-pill-ink`, `--ns-flood-ribbon`, `--ns-flood-ribbon-core`, `--ns-flood-shadow`, `--ns-flood-sheen`, `--ns-flood-wash`, `--ns-font-body`, `--ns-font-display`, `--ns-font-mono`, `--ns-font-script`, `--ns-glass`, `--ns-glass-blur`, `--ns-glass-shadow`, `--ns-glow`, `--ns-grain`, `--ns-gutter`, `--ns-header`, `--ns-heat`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-ink-4`, `--ns-leading`, `--ns-lift`, `--ns-light-1`, `--ns-light-2`, `--ns-light-3`, `--ns-light-spread`, `--ns-light-strength`, `--ns-line`, `--ns-line-soft`, `--ns-lit-edge`, `--ns-menu-dy`, `--ns-menu-row`, `--ns-mesh`, `--ns-mesh-frost`, `--ns-ok`, `--ns-ok-ink`, `--ns-orb-body`, `--ns-orb-cool`, `--ns-orb-core`, `--ns-orb-dawn`, `--ns-orb-deep`, `--ns-orb-edge`, `--ns-orb-grain`, `--ns-orb-ground`, `--ns-orb-halo`, `--ns-orb-inner`, `--ns-orb-key`, `--ns-orb-lift`, `--ns-orb-limb`, `--ns-orb-limb-from`, `--ns-orb-rim`, `--ns-orb-skin-hi`, `--ns-orb-skin-lo`, `--ns-orb-skin-mid`, `--ns-orb-warm`, `--ns-panel`, `--ns-panel-w`, `--ns-prism-edge`, `--ns-prism-glint`, `--ns-prism-sheen`, `--ns-prism-tint`, `--ns-pulse`, `--ns-radius`, `--ns-radius-card`, `--ns-radius-full`, `--ns-radius-lg`, `--ns-radius-sm`, `--ns-radius-xl`, `--ns-raised`, `--ns-range`, `--ns-row`, `--ns-row-compact`, `--ns-segment`, `--ns-selected`, `--ns-series`, `--ns-series-core`, `--ns-series-lilac`, `--ns-series-tint`, `--ns-shadow-dialog`, `--ns-shadow-float`, `--ns-shadow-panel`, `--ns-sheet`, `--ns-sheet-bottom`, `--ns-side`, `--ns-signal`, `--ns-sleep-awake`, `--ns-sleep-deep`, `--ns-sleep-light`, `--ns-sleep-rem`, `--ns-space-1`, `--ns-space-2`, `--ns-space-3`, `--ns-space-4`, `--ns-space-5`, `--ns-space-6`, `--ns-space-8`, `--ns-space-section`, `--ns-stack-on`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-switch-h`, `--ns-switch-w`, `--ns-text-body`, `--ns-text-control`, `--ns-text-display`, `--ns-text-figure`, `--ns-text-headline`, `--ns-text-hero`, `--ns-text-lede`, `--ns-text-meta`, `--ns-text-page`, `--ns-text-record`, `--ns-text-small`, `--ns-text-strong`, `--ns-text-sub`, `--ns-text-title`, `--ns-tile-shadow`, `--ns-time-born`, `--ns-time-color`, `--ns-time-dialog`, `--ns-time-menu`, `--ns-time-page`, `--ns-time-panel`, `--ns-time-toast`, `--ns-tint`, `--ns-tint-ink`, `--ns-toast-bottom`, `--ns-toast-left`, `--ns-touch`, `--ns-tracking-display`, `--ns-tracking-headline`, `--ns-warn`, `--ns-warn-ink`, `--ns-wash-clay`, `--ns-wash-dusk`, `--ns-wash-graphite`, `--ns-wash-ink`, `--ns-wash-sage`, `--ns-wash-sand`, `--ns-weight-light`, `--ns-weight-medium`, `--ns-weight-regular`, `--ns-weight-strong`, `--ns-well`. - Never add Tailwind colour classes inside the component. ```tsx import { StateBar } from "@/components/ui/notchset/state-bar"; ``` ## Parts - A single export that takes props. ## Match the original - Read `components/ui/notchset/state-bar.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 ### Not when ## Mistakes - Recreating the component instead of installing it ## Usage ```tsx "use client"; import * as React from "react"; import { StateBar } from "@/components/ui/notchset/state-bar"; export default function StateBarDemo() { const [opened, setOpened] = React.useState(null); const parts = [ { key: "done", label: "Done", count: 31 }, { key: "review", label: "In review", count: 4 }, { key: "doing", label: "In progress", count: 7 }, { key: "todo", label: "Not started", count: 12 }, ]; return (

{opened ? `Would open the ${parts.find((p) => p.key === opened)!.label.toLowerCase()} tasks` : "Press a state to open its tasks"}

); } ``` ## Props | Prop | Type | Default | What it does | |---|---|---|---| | `label` | `string` | | what it counts, read out with every state ("Route planner v2: tasks by status") | | `parts` | `StatePart[]` | | Required. | | `onSelect` | `(key: string) => void` | | opens the records one state counts | Full docs: https://notchset.dev/components/state-bar ## Customising - Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component. - Dark mode follows the `.dark` class or `data-theme="dark"` on an ancestor (the shadcn and next-themes conventions). - Update later: Commit or stash local changes first (or copy the files), so the update can be undone. Read https://notchset.dev/r/changelog.json for the new versions: a major version, an entry marked breaking or a merge says what to change. Then re-run the install with `--overwrite`, on a branch. It replaces the component's files, the shared helper files they import, and the item's CSS rules in the global stylesheet, so review the whole diff (components, shared files, CSS), re-apply your own edits, and run the app's typecheck, tests and build. ## Accessibility contract (preserve when editing) ## Install ```bash npx shadcn@latest add https://notchset.dev/r/state-bar.json ``` Or add the `@notchset` registry to components.json and run `npx shadcn@latest add @notchset/state-bar`. Every components.json style gets the same files. ## Continue the workflow - [Activity heatmap](https://notchset.dev/components/activity-heatmap) - [Chart](https://notchset.dev/components/chart) - [Inline bar](https://notchset.dev/components/inline-bar) ## Source ### components/ui/notchset/state-bar.tsx ```tsx // Notchset state-bar 2.1.0 · https://notchset.dev/changelog "use client"; import * as React from "react"; import { cn } from "@/lib/utils"; /* * State bar: where things sit right now, as one stacked bar.
