## Deprecation notice
`preact-x` supports `Lazy` component, which can be used as shown [here](https://reactjs.org/docs/code-splitting.html#reactlazy).
Prefer using the `Lazy` component along with `Suspense` instead of this package.

This package is still useful for preact versions < 10

--------------------

Async route component for [preact-router](https://github.com/developit/preact-router)

`npm i -D preact-async-route`

preact-async-route provides `<AsyncRoute> ` tag to load your components lazily.

`<AsyncRoute> ` provides similar props to return a lazily loaded component either as a Promise resolving to the component or return the component in a callback.

`<AsyncRoute> `  also has a loading props, to which you can pass a component to be shown while the component is being lazily loaded.

## Version 2.0
Version 2.0 brings support for a new prop `component`
in order to make usage of already imported components now preact-async-route will support 2 props

1. `component` this will just take the JSX component itself and NOT the function
2. for function calls `getComponent` is the prop

check README :point_down:

## Usage Example
```js
  import { h, render } from 'preact';
  import Router, from 'preact-router';
  import AsyncRoute from 'preact-async-route';
  import Home from './Components/Home/Home.jsx';
  import Terms from './Components/Terms/Terms.jsx';
  import Loading from './Components/Loading/Loading.jsx';
  /** @jsx h */

/**
    arguments passed to getComponent:
      url -- matched url
      cb  -- in case you are not returning a promise
      props -- props that component will recive upon being loaded
  */
  function getProfile(url, cb, props){
  	return import('../component/Profile/Profile.jsx').then(module => module.default);
  }

const Main = () => (
  	<Router>
  		<Home path="/" />
  		<Terms path="/terms" />
  		<AsyncRoute path="/profile/:userid" component={Home} />
  		<AsyncRoute path="/friends/:userid" getComponent={getProfile}
            loading={()=>{return <Loading/>}} />
  	</Router>
  );
  ```
