Framework Agnostic Router for Web Components

Vaadin is happy to announce the first release of its free open source client-side router to use with WebComponents.

Yet another JS router? In order to build applications of web components, you need a router. None of the existing routers fulfilled our needs, so we set out to build one. It comes with these key features:

  1. Small size (< 7kb).
  2. Framework agnostic.
  3. Map URLs to views based on WebComponents.
  4. Express-like syntax for routes.
  5. Implements all features you may expect from a router.
  6. Features include: Child route, Redirects, Callbacks, Lazy loading of views, Animate transitions, Route parameters, Route actions, and much more!
  7. Did I mention that it’s free and open source?

Getting started is easy, Vaadin Router is available as a node module that you can install using npm or yarn.

  $ npm install --save @vaadin/router

And you are ready to go!

You can initialize the router by assigning the region of the DOM where views should be rendered (e.g. a div called outlet):

  import {Router} from '@vaadin/router';
	const outlet = document.getElementById('outlet');
	const router = new Router(outlet);

You can also import it using JS script syntax in e.g. your index page.

Then, set the routing rules of your views:

    {path: '/', component: 'x-home-view'},
    {path: '/users', &nbsp;component: 'x-user-list'},
    {path: '/users/:user', component: 'x-user-profile'},
   {path: '(.*)', component: 'x-not-found-view'},

path is the one you will mostly use, but other parameters could be: children, bundle, component, animate, and action.
