@diso.io/groutcho

Declarative, framework-agnostic router core: URLPattern matching, a redirect engine with loop detection, and a pluggable history store. No DOM dependency in the matching engine — only createBrowserHistory touches window.

npm install @diso.io/groutcho

import { createRouter, createMemoryHistory } from '@diso.io/groutcho';

const store = createRouter({
  routes: {
    Home: { pattern: '/', page: 'Home' },
    Show: { pattern: '/show/:title', page: 'Show' }
  },
  redirects: {
    NotFound: (match) => (match ? false : 'NotFound')
  }
  // history: createMemoryHistory('/')   // for SSR / tests / React Native
});

store.subscribe((match) => console.log(match.route?.name, match.params));
store.go('/show/hi');

Exports: createRouter, createBrowserHistory, createMemoryHistory, Router, Route, MatchResult, logger, and all types.

See the groutcho family README for concepts and the Lit/React bindings.
