Packages

Signals, element helpers, and the pieces nodes are built out of. Plain TypeScript that builds real DOM nodes, no compiler.

The typed route-tree router: params as signals, persistent layouts, typed links, and URL-synced search params. Built on core's public API.

File-based routing, SSR, and prerendering on top of Vite. Write pages and layouts as files; kit wires up the router with typed params.

Unstyled building blocks for common UI patterns. They own the behavior and the accessibility; you own the look.

Dark mode: the visitor's choice, the system preference, and the class on <html> — applied before the first paint, so there is no flash of the wrong theme.

Schema-first forms, ported from Formisch. The valibot schema types the fields, validates the input and produces the submit handler's output.

Scaffolds a new implement app — kit or plain Vite, with Tailwind, primitives, icons, forms, and dark mode as optional addons.

Lint rules for the mistakes types cannot catch: a subscription whose unsubscribe went missing, a misspelled aria attribute, a Lifecycle that wanted to be a Watch. An ESLint plugin, and oxlint runs it too.

The full Lucide icon set as icon components. Each icon is its own module, so bundlers only keep the ones you import.
