ErrorState
A recoverable error screen: optional glyph, title, message, and a retry action. No red: the lens has one accent, so the failure reads from the words. Pairs with AsyncView's error slot.
Installation
npx @glasskit-ui/cli add error-stateInstall the SDK (it provides GlassViewport, useDpad and the stylesheet), then copy these files into your project:
npm install @glasskit-ui/react// components/lib/utils.tsimport { clsx, type ClassValue } from "clsx";import { twMerge } from "tailwind-merge";export type { ClassValue };/** * Merge class names the shadcn way: clsx joins conditionals, tailwind-merge * de-dupes conflicting Tailwind utilities so a consumer's `className` override * wins (e.g. passing `px-2` beats the component's `px-6`). Lens components are * Tailwind utilities + `--gk-*` tokens, so this de-dupe matters. */export function cn(...inputs: ClassValue[]): string { return twMerge(clsx(inputs));}/** * Accessible name from a free-form `label` prop: the label itself when it's a * plain string, otherwise undefined (a ReactNode can't become an aria-label). */export function stringLabel(label: unknown): string | undefined { return typeof label === "string" ? label : undefined;}// components/glasskit/button.tsximport type { ReactNode } from "react";import { cn } from "../lib/utils";/** * <Button> — a D-pad-focusable action. Renders a real <button> carrying * the `focusable` class, so `useDpad()` includes it in spatial navigation * and activates it on Enter/Space (the hook calls `.click()`, which fires * `onClick`). `primary` wears the accent fill; `positive`/`danger` carry the * semantic accept/destroy fills (calls, irreversible confirms); `ghost` is * chrome-less (just text + focus ring + press) for toolbars and icon rows. */export function Button({ children, variant = "secondary", icon, disabled, onClick, type = "button", initialFocus = false, "aria-label": ariaLabel, className,}: { /** The label.

<ErrorState title="No signal" message="Move to an open area and try again." onRetry={refetch}/>Props
| Prop | Type | Default | Description |
|---|---|---|---|
title | ReactNode | "Something went wrong" | The headline. |
message | ReactNode | — | Supporting detail. |
icon | ReactNode | — | Optional leading glyph. |
onRetry | () => void | — | Shows a retry button when set. |
retryLabel | ReactNode | "Retry" | Retry button label. |
EmptyState
The nothing-here screen: optional glyph + title + hint + one action. The quiet sibling of ErrorState: nothing failed, there's just no content yet. Pairs with AsyncView's placeholder slot.
StatusDot
A glanceable sensor / permission / connection indicator. With one accent on the lens, state reads from luminance + motion: on = steady, live = pulsing, off = dim.
