file-loader를 이용한 백그라운드 이미지 불러오기 관련 질문 드립니다
미해결
프론트엔드 개발환경의 이해와 실습 (webpack, babel, eslint..)
안녕하세요 수업 내용대로 file-loader를 이용하여 백그라운드 이미지를 불러오는 실습을 진행하다가 에러가 발생하여 질문 드립니다. 강의에서는 file-loader를 사용하지 않고 .css 파일에서 style-loader와 css-loader만 사용하고 빌드했을 경우에는 에러가 나야하는데 저는 에러가 나지 않고 브라우저에서 열어 봤을 때에 바로 백그라운드 이미지가 나옵니다. 또한 file-loader가 포함된 코드를 webpack.config.js에 추가했을때에는 빌드는 잘 되는데 오히려 브라우저에서 백그라운드 이미지가 나오지 않습니다. style-loader와 css-loader에서 file-loader의 역할을 대신해주도록 업데이트가 된걸까요..? 아래에 패키지 버전과 코드를 남겨드립니다. 패키지 버전 "dependencies" : { "css-loader" : " ^6.2.0 " , "file-loader" : " ^6.2.0 " , "style-loader" : " ^3.2.1 " } } app.js import * as math from ' ./math.js ' import ' ./app.css ' console . log ( math . sum ( 1 , 2 )); app.css body { background-image : url ( bg.png ); } webpack.config.js (백그라운드 이미지 뜨는 경우) const path = require ( ' path ' ); module . exports = { mode: ' development ' , entry: { main: ' ./src/app.js ' }, output: { path: path . resolve ( ' ./dist ' ), filename: ' [name].js ' }, module: { rules: [ { test: / \. css $ / , use: [ ' style-loader ' , ' css-loader ' ] }, ] } } webpack.config.js (백그라운드 이미지 뜨지 않는 경우) const path = require ( ' path ' ); module . exports = { mode: ' development ' , entry: { main: ' ./src/app.js ' }, output: { path: path . resolve ( ' ./dist ' ), filename: ' [name].js ' }, module: { rules: [ { test: / \. css $ / , use: [ ' style-loader ' , ' css-loader ' ] }, { test: / \. png $ / , // .png 확장자로 마치는 모든 파일 loader: " file-loader " , options: { publicPath: " ./dist/ " , // prefix를 아웃풋 경로로 지정 name: " [name].[ext]?[hash] " , // 파일명 형식 }, }, ] } } 아래와 같은 코드에서 빌드했을 때에 dist/main.js 코드 입니다. /* * ATTENTION: The "eval" devtool has been used (maybe by default in mode: "development"). * This devtool is neither made for production nor for readable output files. * It uses "eval()" calls to create a separate source file in the browser devtools. * If you are trying to read the output file, select a different devtool (https://webpack.js.org/configuration/devtool/) * or disable the default devtool with "devtool: false". * If you are looking for production-ready output files, see mode: "production" (https://webpack.js.org/configuration/mode/). */ /** *** */ ( () => { // webpackBootstrap /** *** */ " use strict " ; /** *** */ var __webpack_modules__ = ( { /***/ " ./node_modules/css-loader/dist/cjs.js!./src/app.css " : /* !***********************************************************!*\ !*** ./node_modules/css-loader/dist/cjs.js!./src/app.css ***!
