react-code-splitting ✂️
You're working on a great app powered by React, bundled with webpack and your bundle size increases ... You're in the right place to solve this modern JS apps nightmare.
Prerequisite
- You're using Webpack 2
- You've polyfilled Promise to support old browser
How-to
Without code splitting
<Login /> + <Home /> are loaded at the first start
import Login from './Login'
import Home from './Home'
const App = ({ user }) => (
<Body>
{user.loggedIn ? <Route path="/" component={Home} /> : <Redirect to="/login" />}
<Route path="/login" component={Login} />
</Body>
)With code splitting
You're not logged in ? <Login /> component is the only loaded, <Home /> will be loaded when the user will be logged in.
Use componentProps to pass props to lazy loaded component.
import Async from 'react-code-splitting'
import Login from './Login'
const Home = () => <Async load={import('./Home')} />
const LostPassword = props => <Async load={import('./LostPassword')} componentProps={props}/>
const App = ({ user }) => (
<Body>
{user.loggedIn ? <Route path="/" component={Home} /> : <Redirect to="/login" />}
<Route path="/login" component={Login} />
<Route path="/lostpassword" component={LostPassword} />
</Body>
