안녕하세요. usePermissions.ts 만들고 app.tsx 에서 불러오게 했는데요 import {useEffect} from 'react'; import {Alert, Linking, Platform} from 'react-native'; import {check, PERMISSIONS, request, RESULTS} from 'react-native-permissions'; function usePermissions() { // 권한 관련 useEffect(() => { if (Platform.OS === 'android') { check(PERMISSIONS.ANDROID.ACCESS_FINE_LOCATION) .then(result => { console.log('check location :', result); if (result === RESULTS.BLOCKED || result === RESULTS.DENIED) { Alert.alert( '이 앱은 위치 권한 허용이 필요합니다.', '앱 설정 화면을 열어서 항상 허용으로 바꿔주세요.', [ { text: '네', onPress: () => Linking.openSettings(), style: 'default', }, { text: '아니오', onPress: () => console.log('No Pressed'), style: 'cancel', }, ], ); } }) .catch(console.error); } else if (Platform.OS === 'ios') { check(PERMISSIONS.IOS.LOCATION_ALWAYS) .then(result => { if (result === RESULTS.BLOCKED || result === RESULTS.DENIED) { Alert.alert( '이 앱은 백그라운드 위치 권한 허용이 필요합니다.', '앱 설정 화면을 열어서 항상 허용으로 바꿔주세요.', [ { text: '네', onPress: () => Linking.openSettings(), }, { text: '아니오', onPress: () => console.log('No Pressed'), style: 'cancel', }, ], ); } }) .catch(console.error); } if (Platform.OS === 'android') { check(PERMISSIONS.ANDROID.CAMERA) .then(result => { if (result === RESULTS.DENIED || result === RESULTS.GRANTED) { return request(PERMISSIONS.ANDROID.CAMERA); } else { console.log(result); throw new Error('카메라 지원 안 함'); } }) .catch(console.error); } else { check(PERMISSIONS.IOS.CAMERA) .then(result => { if ( result === RESULTS.DENIED || result === RESULTS.LIMITED || result === RESULTS.GRANTED ) { return request(PERMISSIONS.IOS.CAMERA); } else { console.log(result); throw new Error('카메라 지원 안 함'); } }) .catch(console.error); } }, []); } export default usePermissions;  요런 에러가 발생해서요. 제가 또 뭘 잘못했을까요..    

남겨주신 노마크코더님의 영상과 기술블로그 글을 보았는데요.DOM 의 풀네임 (Document Object Model) 말처럼HTML, CSS, JS 파일들을 객체화하여 따로 분리하여 연결해주는 모델링이 속도가 빠르게 해주는 핵심 이유이며,객체화를 통해 브라우저에서 직접 모든 렌터, 레이아웃을 계산하는게 아닌 Offline 상태에서 계산하여 결과값만 브라우저에 나타내기 때문이다. 라고 이해를 하고 있는데 맞을까요?이런 React의 동작방식과 작업방식이 가장 빠른건 아니지만웬만한 웹에서 빠르게 동작하고 충분히 빠르고 효율적이기에 많은 서비스들에서 사랑 받고 있는 프레임워크다. 혹시 이렇게 정리하는게 조금 제가 잘 이해를 못 하고 있는 부분일지요.

안녕하세요 콘솔에 404 에러가 떠서 목서버를 확인해보니 아래와 같은 오류가 떴는데 이러한 경우 어떻게 해결할 수 있을까요..{ "error": { "name": "usageLimitError", "header": "Usage limit reached", "message": "Your team plan allows 1000 mock server calls per month. Contact your team Admin to up your limit." } }

npm i -D 이거는 무슨 의미 인가요?

ngrok 연결도 다 했고 url에다가 POSTMAN으로 GET 요청하면 데이터도 잘 불러와지는데 결과창을 보면 데이터가 불러와지지 않아 화면이 제대로 뜨질 않네요...해결 방법이 있을까요?  

안녕하세요 axios 코드 실행 하면 아래 사진과 같이 오류가 뜹니다.

강의에서 보면 코드 작성하면서 옵션들 추가할 때마다 어떤 옵션이 있는지 미리보기처럼 적혀져있는데,제가 vscode를 사용해서 그런건지 저는 따로 옵션들의 이름이 미리보기형식처럼 나오지 않아요ㅠㅠ혹시 적용할 때 타입 정의로 찾아보는 방법 말곤 강의처럼 나올 수 있게 하는 방법이 있을까요??

안녕하세요 메인 페이지 출력이 안되어서 질문 남깁니다해당 코드와 실행결과 사진으로 첨부했습니다 

안녕하세요macOS Ventura 13.2 PC에 react-native init TestApp 실행 시 ruby 2.7.6 버전이 설치되어 있어야 한다고 확인했습니다.현재 제 PC 기준 설치할 수 있는 ruby 버전은 위와 같습니다.방법이 있는지 문의드립니다.고맙습니다

위 사진처럼 setProducts 밑에 console.log를 해봤는데한번 출력될 줄 알았는데 왜 두 번 출력되는 건가요?

안녕하세요~최초 npx react-native init 프로젝트명 커맨드로 프로젝트를 만들면 build.gradle 파일에는 아래의 react.gradle 이 존재하지 않습니다.apply from: "../../node_modules/react-native/react.gradle"이부분은 향후에도 지원하지 않고 deprecated 된다고 하네요.그래서 https://github.com/facebook/react-native/blob/main/template/android/app/build.gradle 여기 공식 github 에도 나와있지만 이제부턴 apply plugin: "com.facebook.react" 를 쓴다고 하고 프로젝트 init하면 default도 그렇게 되어 있습니다. 그런데 문제는!이러한 build.gradle 환경에서 android 빌드해보면 아래와 같은 에러가 발생합니다.bundleDebugJsAndAssets 를 :app 에서 찾을 수 없다고 나오는데 어떻게 해결하면 될까요? info Starting JS server...info Installing the app...5 actionable tasks: 5 up-to-dateFAILURE: Build failed with an exception.* What went wrong:Could not determine the dependencies of task ':app:generateBundledResourcesHashDebug'.> Task with path 'bundleDebugJsAndAssets' not found in project ':app'.* Try:> Run with --stacktrace option to get the stack trace.> Run with --info or --debug option to get more log output.> Run with --scan to get full insights.* Get more help at https://help.gradle.orgBUILD FAILED in 4serror Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081FAILURE: Build failed with an exception.* What went wrong:Could not determine the dependencies of task ':app:generateBundledResourcesHashDebug'.> Task with path 'bundleDebugJsAndAssets' not found in project ':app'. 아래와 같은 이슈인거 같은데 known 이슈로 지금 디버깅 중인걸까요?https://github.com/microsoft/react-native-code-push/issues/2418  

안녕하세요. 수업 잘 듣고 있습니다!수업관련 질문은 아니지만 일반적인 구현방법도 이런가해서 문의 남겨봅니다^^이미지 업로드 화면에서업로드 할 사진을 선택하면 서버측으로 먼저 이미지를 전송하는 방식으로 구현하셨는데 이미지 선택 시에는 로컬(클라이언트PC)의 이미지로 보여주고 [상품 등록하기] 버튼을 눌렀을 때 서버로 업로드 하면서 DB에 등록하는 것이 어떨까해서요.이미지를 계속 변경하면 서버에 업로드가 되는 듯 하여...문의한번 해봅니다^^ 다른 수강생분들에게도 문제 해결에 도움을 줄 수 있도록 좋은 질문을 남겨봅시다 :) 1. 질문은 문제 상황을 최대한 표현해주세요.2. 구체적이고 최대한 맥락을 알려줄 수 있도록 질문을 남겨 주실수록 좋습니다. 그렇지 않으면 답변을 얻는데 시간이 오래걸릴 수 있습니다 ㅠㅠex) A라는 상황에서 B라는 문제가 있었고 이에 C라는 시도를 해봤는데 되지 않았다!3. 먼저 유사한 질문이 있었는지 꼭 검색해주세요!

안드로이드 NDK와 같은 스마트폰 OS 네이트브 코드를 개발하면서 UI 를 리액트 네이티브로 구현할 수 있는지 궁금합니다.저는 gstreamer 파이프라인을 구현한 앱을 만들고 싶습니다. 또 opencv 도 사용하고요, 딥러닝 라이브러리도 사용하고 싶습니다. 이런 부분은 아마도 안드로이드 NDK 와 같은 걸 써야 할 것 같습니다. 아이폰은 잘 모르지만 아마 iOS 에도 NDK 비슷한 것이 있을 것 같습니다. 이렇게 플랫폼에 종속된 기술을 각 플랫폼 별로 구현해야 하는 것은 피할 수 없을 것 같습니다. 그러나 UI 부분은 리액트 네이티브로 원소스로 구현하고 싶습니다.이런 식의 구현을 할 수 있는지, 할 수 있다면 어떤 참고 자료가 있을지 궁금합니다.

안녕하세요 강사님해당 상품을 클릭했을때 url은 바뀌지만 상품상세페이지로 화면은 바뀌지 않는 오류가 발생했습니다(새로고침하면 화면이 바뀌긴 합니다)다른 수강생들의 비슷한 질문답변을 참고하여 <React.StrictMode>를 지워도보고 react-router-dom 버전도 5.2.0이고 Route path도 "/products/:id"라고 적었는데 여전히 오류가 해결되지 않습니다https://github.com/kanghanju/grab-market-client/commit/01c0657f4f64398b47493c1b2c3b44836bf1a785#여기는 Link태그 해당 수업코드 파일입니다!
