Installation — kloq React calendar

kloq ships two ways. npm gives you the compiled, typed build. The source registry copies the whole calendar — engine, views, themes, design mode — into your repo as licensed source you can edit, through one shadcn CLI command. Same component, same API; the difference is whether the code lives in node_modules or in your tree.

npm — the compiled build

terminal

npm install kloq

react ≥ 19 and Tailwind CSS v4 are assumed. Import the stylesheet once, in your root layout — CSS imported inside a page or component only reaches that route:

app/layout.tsx

import "kloq/styles.css";

Import	Notes
`kloq`	The `<Kloq>` component, chrome parts, types, store helpers, the command registry, quick add, ICS.
`kloq/themes`	The theme system: `setTheme` / `setScheme`, and the pre-paint restore script for zero-flash SSR.
`kloq/settings`	The optional preferences dialog and its `KloqPreferences` model.
`kloq/design-mode`	The ⌥D design-mode surface, importable on its own.
`kloq/styles.css`	The single stylesheet. Import once.

Registry — edit the source

The registry delivers the same calendar as source files under components/kloq/, so a custom slot is just another file and a spring tweak is a line you can edit. Use is governed by the Kloq Source License. Source access comes with a registry token — join the waitlist for yours (KLOQ_REGISTRY_TOKEN in .env.local); point the CLI at kloq once:

components.json

{
  "registries": {
    "@kloq": {
      "url": "https://kloq.dev/r/{name}.json",
      "headers": { "Authorization": "Bearer ${KLOQ_REGISTRY_TOKEN}" }
    }
  }
}

terminal

npx shadcn@latest add @kloq/kloq

The CLI lands the library under components/kloq/ and installs its five npm dependencies (@base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge). Import paths change from kloq/... to @/components/kloq/...:

app/layout.tsx

import "@/components/kloq/styles/kloq.css";

Import	Type	Notes
`@/components/kloq`	component + API	Everything the `kloq` npm entry exports.
`@/components/kloq/lib/themes`	theme system	`kloq/themes`.
`@/components/kloq/settings`	settings dialog	`kloq/settings`.
`@/components/kloq/design-mode`	inspector	`kloq/design-mode`.
`@/components/kloq/styles/kloq.css`	stylesheet	`kloq/styles.css`.

Light and dark

kloq follows a dark class on <html> — the coss / shadcn convention — and leaves that class alone unless you call setScheme. If your app runs no scheme convention at all (no dark or light class on <html>), the calendar follows the OS on its own, scoped to itself, so it never paints white on a dark page.

Requirements

React 19+, Tailwind CSS v4, a browser with pointer events and WAAPI (every evergreen browser), and a container with a real height — <Kloq> is h-full and renders into whatever box you give it. There is no window-level layout: two calendars on one page work fine.
