요약개발환경에서 src/assets/.... 에 있는 이미지 파일을 제대로 참조하는 방법이 궁금합니다. 구성요소프로젝트의 구성요소는 아래와 같습니다.public[index.html, favicon.ico]src[assets[image0, image1...], index.js 등] 설치된 패키지는 아래와 같습니다. "webpack": "^5.75.0", "webpack-cli": "^5.0.1", "webpack-dev-server": "^4.11.1" // 본 강의에선 4.x.x 버전을 사용하지만... // 5 version을 공부해야해서... 죄송합니다 😥 설명dev server를 실행시켜 개발할 때,js 파일을 수정하면 바로 반영이 되는 걸 확인했습니다. 그런데 이미지 파일의 경우 다른 파일을 참조하도록 하면 해당 파일을 불러오지 못합니다. 그리고 build된 파일을 참조합니다.예로들어 정적 이미지 파일이 ./src/assets/image_0.jpg 라면,dev server로 실행시켜 확인하면 HOST/dist/assets/images/[hash][ext][query].jpg 이렇게 되어있습니다. (경로가 다름)그리고 build를 하면 분명 assets 디렉토리엔 다수의 이미지 파일이 존재함에도 불구하고 코드에서 사용된 이미지 파일만 build됩니다.그러면 만약 코드내부에서 동적으로 다른 static image 파일을 참조하게 된다면 해당 이미지가 없기 때문에 오류가 날텐데 이런건 어떻게 처리해야하나요? 코드const path = require('path'); const { BannerPlugin, DefinePlugin } = require('webpack'); const childProcess = require('child_process'); const HtmlWebpackPlugin = require('html-webpack-plugin'); const MiniCssExtractPlugin = require('mini-css-extract-plugin'); const isDevMode = (process.env.NODE_ENV || 'development').trim() === 'development'; console.log('is DEV mode?', isDevMode); console.log('__dirname: ', __dirname); module.exports = { mode: isDevMode ? 'development' : 'production', // entry: webpack 시작되는 부분이라고 생각하면 된다. entry: { main: './src/index.js', }, /** * output * entry point를 기준으로 * 모든 .js 파일을 합쳐서 하나의 bundle 파일로 만드는데, * 이걸 어디에 저장할 것인지 지정하는 option */ output: { path: path.resolve(__dirname, 'dist'), filename: isDevMode ?

'style-loader' : { loader: MiniCssExtractPlugin.loader, options: { publicPath: '', }, }, // translates css into common JS 'css-loader', 'postcss-loader', // complies sass to css 'sass-loader', ], }, { test: /\.(png|svg|jpg|jpeg|gif)$/i, exclude: [/node_modules/], type: 'asset/resource', parser: { dataUrlCondition: { // 크기가 8kb 미만인 파일은 inline 모듈로 처리되고 그렇지 않으면 resource 모듈로 처리됩니다. maxSize: 4 * 1042, }, }, // generator: { // publicPath: './assets/', // outputPath: './assets/', // }, }, { test: /\.js$/, exclude: [/node_modules/], loader: 'babel-loader', }, { test: /\.(woff|woff2|eot|ttf|otf)$/i, exclude: [/node_modules/], type: 'asset/resource', }, ], }, plugins: [ /** * 개발할 때 API 서버주소, * 배포했을 때 API 서버주소를 설정하는 Plugin */ // new DefinePlugin({ // NODE_ENV: 'development', // }), new BannerPlugin({ banner: `Build Date: ${new Date().toLocaleString()} Commit Version: ${childProcess.execSync('git rev-parse --short HEAD')} Author: ${childProcess.execSync('git config user.name')}`, }), new HtmlWebpackPlugin({ template: './public/index.html', templateParameters: { env: isDevMode ? '개발용' : '배포용', }, minify: !isDevMode ? { collapseWhitespace: true, removeComments: true, } : false, }), ...(!isDevMode ? [ new MiniCssExtractPlugin({ filename: isDevMode ? '[name].css' : '[name].[contenthash].css', chunkFilename: isDevMode ? '[id].css' : '[id].[contenthash].css', }), ] : []), ], };  결론즉 정리하자면,개발모드일 때 정적 이미지 파일을 참조하도록 설정을 어떻게 해야하나요?왜 build할 땐 이미지 파일이 코드에서 사용중인 것만 빌드 되나요? 답변 주시면 감사하겠습니다.

안녕하세요 강의와 연관은 없지만 어디에 질문할지 몰라 여기에 질문 남깁니다. 제가 기존 노드 교과서를 이북으로 구매하여 잘 보고 있습니다. 3판이 나오면 이북도 새로 나오는 건가요? 맞다면 이북 같은 경우 출시 예정일이 언제인지도 궁금합니다.  감사합니다!!

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.  검색에서 title_like 중에 같은 부분만 색상을 바꿀수있나요~?!nflinflearn <- 이런식으로 결과값에 같은 부분을요 지금은 볼드지만 색상으로... 가능할까요?

안녕하세요 선생님안드로이드 스튜디오 사용하여 강의 수강중인데 run 콘솔창이위와 같이 너무 지저분하게 나와서요,, 깔끔하게 보고싶어서 설정을 하려는데 방법이 잘 안나오는 것 같아서 질문드립니다. 필요로 하는 것 내용들만 필터링 해서 볼 수 있을까요?

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

Description: Web server failed to start. Port 8080 was already in use.~(1) 정적 HTML페이지를 생성 저장 후, 실행시키니 위와 같은 에러가 나타났습니다. 그래서 터미널에서 sudo kill 을 실행시켰더니 인텔리제이마저 종료되어 버렸습니다.(2) 다시 인텔리제이를 실행시킨 후 application.yml 에서 server.port: 8081 을 추가하고 실행시키니 -> 프로젝트는 이상없이 실행이 되었는데, 정적 html 페이지의 주소가 8080으로 정상적으로 연결되지만 / 8081로 연결하니 '사이트에 연결할 수 없음'으로 나타납니다.여기서부터 이해가 되지 않아 구글링 및 자주하는 질문을 확인해도 답을 찾을 수 없어 문의를 남깁니다.(1) sudo kill -9에서 8080에서의 PID를 제거하니 인텔리제이마저 종료된 것이 무슨 의미일까요?(2) application.yml에 8081을 추가하지 않고도 프로젝트 실행되게 하려면 어떤 조치가 필요할까요?(3) 8081을 추가하고 정적 html은 8080으로 열리는 게 정상인 것일까요? 만약 그렇다면 그 이유에 대한 설명을 부탁드립니다.(참고로 이 현상이 발생되기 전에, 인텔리제이에서 직접 정적 html을 브라우저에 띄우면 -> 포트63342에서 띄워져서 -> 인텔리제이 preferences에서 Built-in Server Port가 63342 로 되어 있는 것을 8080으로 수정하였습니다.)
