Babel
ECMAScript6를 지원하지 않는 환경에서 ECMAScript6 Syntax를 사용할 수 있게 해줍니다.
Webpack
모듈 번들러입니다.
Browserify 처럼 브라우저 위에서 import(require)을 할 수 있게 해주고 자바스크립트 파일들을 하나로 묶어 줍니다.
webpack-dev-server
webpack에서 지원하는 간단한 개발서버로써 별도의 서버를 구축하지 않아도 웹서버를 열 수 있으며 hot-loader 를 통하여 코드가 수정될때마다 자동으로 리로드되게 할 수 있습니다.
프로젝트를 위한 폴더 생성 및 npm 초기화 - 폴더명 myFristApp

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.
See `npm help json` for definitive documentation on these fields
and exactly what they do.
Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.
Press ^C at any time to quit.

package.json에 webpack-dev-server 스크립트 추가
package.json에 "dev-server":"webpack-dev-server" 추가해야 합니다.
추후 개발 서버를 실행하기 위해서 필요합니다.

webpack 설정 - webpack.config.js
프로젝트 폴더에 webpack 설정파일인 webpack.config.js 을 생성하고 아래의 내용을 입력합니다.
var webpack = require('webpack');
var path = require('path');
module.exports = {
entry: [
'webpack-hot-middleware/client',
'./src/index.js'
],
output: {
path: __dirname + '/public/',
filename: 'bundle.js'
},
devServer: {
hot: true,
inline: true,
port: 4000,
contentBase: __dirname + '/public/',
},
module: {
loaders: [
{
test: /\.js$/,
loaders: ['react-hot-loader', 'babel-loader'],
include: path.join(__dirname, 'src')
},
{
test: /\.less$/,
loader: 'style-loader!css-loader!less-loader' // use ! to chain loaders
},
{
test: /\.css$/,
loader: 'style-loader!css-loader'
},
{
test: /\.scss$/,
loader: 'style-loader!css-loader!sass-loader'
},
{
test: /\.(png|jpg)$/,
loader: 'url-loader?limit=8192' // inline base64 URLs for <=8k images, direct URLs for the rest
}
]
},
plugins: [ new webpack.HotModuleReplacementPlugin() ]
}react app 만들기
1. 처음에 생성한 myFirstApp 에 public, src 폴더를 생성합니다.
webpack.config.js에서 개발 서버가 바라볼 기본 폴더는 public가 됩니다.
$ cd myFirstApp
$ mkdir public
$ mkdir src
2. public 폴더에 index.html 파일을 아래와 같이 생성합니다.
$ cd public/index.html
-- index.html에 간략한 내용 입력
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>React App with Babel + webpack</title>
</head>
<body>
<div id="contents"></div>
<script src="bundle.js"></script>
</body>
</html>
3. src 폴더에 components 폴더를 생성합니다.
src 폴더의 하위에 components 폴더를 만들고 src/components 에 Contents.react.js 파일을 생성하고 아래의 내용을 입력합니다.
$ cd ../src
$ mkdir components
$ vi Contents.react.js
-- Contents.react.js 파일의 내용
import React from 'react';
class Contents extends React.Component {
render() {
return ( <h1>React + Webpack + Babel First Apps</h1> );
}
}
4. 개발 서버를 실행합니다.
브라우저에서 http://localhost:4000에 접속하시면 결과를 확인할 수 있습니다.
$ cd myFirstApp
$ npm run dev-server
