One router. Any framework. The platform underneath.

A lightweight SPA router built on the browser Navigation API — a zero-dependency TypeScript core with thin Svelte 5, React and Vue 3 adapters.

🧩

Framework-agnostic core

Matching, guards, lazy-loading and the async-commit state machine live in pure TypeScript with zero runtime dependencies. Use it directly, or through a 1-file adapter.

🌐

Built on the Navigation API

Link clicks are intercepted natively — modifier-clicks, target="_blank" and downloads behave correctly for free. No History API guesswork.

🪶

Tiny

The core is ~4 KB minified (1.8 KB gzipped) with zero runtime dependencies and sideEffects false for full tree-shaking. Each adapter adds only ~0.5 KB gzipped on top.

🔒

Type-safe navigation

Declare routes "as const" and navigate() only accepts known paths at compile time — "/users/:id" becomes `/users/${string}`, with optional ?query /

Svelte 5, React & Vue 3

One immutable-snapshot external store, three native bridges — createSubscriber, useSyncExternalStore and shallowRef. Correct, tear-free updates everywhere.

Guards, lazy & nested layouts

beforeLoad guards run root→leaf with an abort signal, redirects and blocking. Layout components persist across child navigations via stable identity.
