preact-router

preact-router

Connect your Preact components up to that address bar.

preact-router provides a <Router /> component that conditionally renders its children when the URL matches their path. It also automatically wires up <a /> elements to the router.

💁 Note: This is not a preact-compatible version of React Router. preact-router is a simple URL wiring and does no orchestration for you.

If you're looking for more complex solutions like nested routes and view composition, react-router works great with preact as long as you alias in preact-compat. React Router 4 even works directly with Preact, no compatibility layer needed!

Usage Example

import Router from 'preact-router';
import { h, render } from 'preact';
/** @jsx h */

const Main = () => (
	<Router>
		<Home path="/" />
		<About path="/about" />
		<Search path="/search/:query" />
	</Router>
);

render(<Main />, document.body);

If there is an error rendering the destination route, a 404 will be displayed.

Handling URLS

:information_desk_person: Pages are just regular components that get mounted when you navigate to a certain URL. Any URL parameters get passed to the component as props.

Defining what component(s) to load for a given URL is easy and declarative. You can even mix-and-match URL parameters and normal props.

<Router>
  <A path="/" />
  <B path="/b" id="42" />
  <C path="/c/:id" />
  <D default />
</Router>

Lazy Loading

Lazy loading (code splitting) with preact-router can be implemented easily using the AsyncRoute module:

import AsyncRoute from 'preact-async-route';
<Router>
  <Home path="/" />
  <AsyncRoute
    path="/friends"
    component={ () => import('./friends') }
  />
  <AsyncRoute
    path="/friends/:id"
    component={ () => import('./friend') }
    loading={ () => <div>loading...</div> }
  />
</Router>
