or

How to use

Example 1:

import lazify from 'react-lazify';

const loadComponent = (name) => lazify(() => System.import(`pages/${name}.jsx`));

// ...
// render()

<Router>
    <div>
        <Route exact path="/" component={ loadComponent('Home') }/>
        <Route path="/settings" component={ loadComponent('Settings') }/>
    </div>
</Router>

System.import is a Webpack function that can load chunks. Also webpack can automatically generate a chunks that had dynamic names.

Example 2:

import lazify from 'react-lazify';

const MyComponent = lazify(() => System.import('components/MyComponent.jsx'), <Spinner />);

// ...
// render()

<MyComponent some={ 'prop' } that={ 'will' } be={ 'passed' } to={ 'loaded' } component />

Here we pass second optional argument to function lazify(load, [prompt]), that will be display during component loading.
