claddcn-svelte

The cladd.io skin for shadcn-svelte.

Install into a project

# in the root of a shadcn-svelte project
npx git+https://git.kotikot.com/lib/claddcn-svelte.git init --strip-vars

init:

1. copies claddcn.css next to your Tailwind entry and @imports it;
2. --strip-vars removes your old :root / .dark / @theme inline token blocks (claddcn defines every shadcn token, and blocks after the import would win);
3. overwrites $lib/components/ui/* with the cladd versions and backs up the old files to .claddcn-backup/<timestamp>/;
4. extends cn() so tailwind-merge understands text-cladd-xs, h-cladd-md, etc.;
5. installs @fontsource-variable/geist and geist-mono, using bun, pnpm, yarn or npm.

Flags: --css <file> (if components.json points at the wrong CSS), --only button,card, --no-install, --dry.

As a shadcn-svelte registry: npx shadcn-svelte registry build → serve static/r → npx shadcn-svelte add https://…/r/button.json.

Utility classes for hand-written markup

cladd-surface (+ cladd-gradient, cladd-fill, cladd-gradient-fill, cladd-outline), cladd-cut, cladd-ghost, cladd-hoverable, cladd-clickable, cladd-focusable, cladd-segment (active via aria-current="page" / data-state="active"), cladd-section-title, cladd-color-{neutral,brand,red,pink,purple,blue,cyan,lime,green,yellow,orange}, cladd-level-{1..5}.

Tailwind tokens: bg-cladd-surface, bg-cladd-surface-next, text-cladd-fg-soft, text-cladd-primary, h-cladd-md, rounded-cladd-md, rounded-cladd-panel, shadow-cladd-outline, text-cladd-xs, …

Nested .cladd-surface elements step one level deeper automatically (1–5). cladd does this with React context. Here it comes from selector depth, so it also works in plain markup.
