webpack メモ - Web - HomeMadeGarbage

今までGulpを使っていたけど初めて webpack を立ち上げてみたのでメモ。

とりあえず、下記のところまでは出来た。
・webpackでsassをコンパイル、cssファイルに書き出す
・webpack-dev-server でファイルを監視しコンパイルとリロード

index.js

// JS
import { sub } from "./js/sub";
sub();

// CSS
import './css/styles.scss';

// JS

import { sub } from "./js/sub";

ファイル構成

node_modules
package-lock.json
package.json
public
　- index.html
src
　- css
　- js
　- index.js

実行

npm start　

webpack-dev-server の起動

npm run build

webpack の実行

まだ設定が必要になるところは増えそうだけど
とりあえず最低限SASSコーディング環境までは立ち上げ出来た感じだろうか…
