WEBPACK is module bundler
많은 파일들을 가져와서, webpack에게 주면, webpack은 static 파일로 변환해준다.(브라우저도 알아들을 수 있도록 해준다.)
file => webpack => file (compatible files) for browser.
***npm install webpack webpack-cli*** => webpack-cli는 터미널에서 webpack을 쓸 수 있게 해준다.
***webpack.config.js 파일 생성***
package.json 에서, 노드 서버와, webpack이 다르게 running 할 수 있도록 만들어주면 편리하다.
ex)
"dev:assets": "WEBPACK_ENV=development webpack",
"build:assets": "WEBPACK_ENV=production webpack",
npm run dev:assets => running server
npm run build:assets => running webpack
webpack.config.js file is fully 100% client code
webpack.config.js file doesn't work with server code
"babel-node"를 쓸 수가 없다. => THEREFORE, you need to work with old JavaScript on webpack.config.js
ex)
instead of 'export / import' => modlue.exports = config;
WEBPACK has TWO things (entry, output)
entry: where your file comes from.
output: where do you want to put it? (output should be an Object)
path.resolve returns a full path from the root of your computer to the file.
path.resolve creates the absolute path.
path.join joins two paths together.
- regular expression을 scss or sass 사용해서 파일을 찾는다.
*npm install node-sass
*npm install autoprefixer
1. sass-loader => normal CSS
2. postcss-loader =>compatible CSS files with browsers(interpreter) ex) autoprefixer
3. css-loader => pure CSS files
4. extract CSS texts => / output: 'static' folder / plugins: [new ExtractCSS("style.css")]
***웹펙 순서***
자바스크립트와 반대로 아래에서 부터 위로 올라간다.
