# 설치 가이드

1. 코드 내려받기

git clone https://github.com/didierfranc/react-code-splitting

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd react-code-splitting

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm install

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

npm start

개발/실행 서버를 켭니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

# react-code-splitting ✂️

`react-code-splitting` is an "old" library, React has implemented a great solution since and it's called [React.lazy](https://reactjs.org/docs/code-splitting.html#reactlazy) go get it !

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+](https://webpack.js.org/)
- You've polyfilled ***Promise*** to support old browser

## How-to

#### Without code splitting

`<Login />` + `<Home />` are loaded at the first start
```jsx
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.

```jsx
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>
)
```
