Vaadin Router

API documentation

Vaadin Router is a small and powerful client-side router JS library. It uses the widely adopted express.js syntax for routes (/users/:id) to map URLs to Web Component views. All features one might expect from a modern router are supported: async route resolution, animated transitions, navigation guards, redirects, and more. It is framework-agnostic and works equally well with all Web Components regardless of how they are created (Polymer / SkateJS / Stencil / Angular / Vue / etc).

Vaadin Router is a good fit for developers that do not want to go all-in with one framework, and prefer to have freedom in picking the components that work best for their specific needs.

npm install --save @vaadin/router

import {Router} from '@vaadin/router';

const router = new Router(document.getElementById('outlet'));
router.setRoutes([
  {path: '/', component: 'x-home-view'},
  {path: '/users', component: 'x-user-list'}
]);

Browser support

A specific version of Vaadin Router supports the same browsers as the Vaadin platform major version which includes that version of Vaadin Router. See Vaadin platform release notes for details on included Vaadin Router version and supported technologies. The Supported Technologies section is typically listed in the release notes of the first publicly available release of a Vaadin platform major version (for example Vaadin 18.0.1 since 18.0.0 was skipped).
