Summary of Changes
Hello @JWLEE30115, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
이 풀 리퀘스트는 새로운 QR 코드 생성기 기능을 도입합니다. 사용자가 텍스트나 URL을 입력하면 외부 API를 통해 QR 코드를 생성하고, 생성된 이미지를 다운로드할 수 있는 독립적인 웹 페이지입니다. 이 구현은 기본적인 스타일링과 클라이언트 측 로직을 통해 간단한 사용자 경험을 제공하는 데 중점을 둡니다.
Highlights
- 새로운 기능: QR 코드 생성기 기능이 추가되었습니다.
- 프론트엔드 구현: HTML, CSS, JavaScript가 단일 파일에 포함된 웹 페이지입니다.
- API 연동:
api.qrserver.com을 사용하여 QR 코드를 생성합니다. - 주요 기능: 사용자가 텍스트나 URL을 입력하여 QR 코드를 생성하고 다운로드할 수 있습니다.
- 오류 처리: 빈 입력 및 API 호출 실패에 대한 기본적인 오류 처리가 포함되어 있습니다.

Code Review
이 PR은 QR 코드 생성기 웹 애플리케이션을 추가합니다. 전반적으로 잘 작성되었으며, 기능적으로 올바르게 동작합니다. 코드 품질과 안정성을 더욱 향상시키기 위해 몇 가지 제안 사항을 남깁니다. 주요 내용은 메모리 누수 방지를 위한 객체 URL 관리, CSS 유지보수성 향상, 그리고 스크립트 실행 시점의 안정성 확보에 관한 것입니다. 파일 이름에 대한 권장 사항도 포함되어 있습니다. 자세한 내용은 각 주석을 확인해주세요.

URL.createObjectURL()로 생성된 객체 URL은 수동으로 해제하지 않으면 메모리 누수를 일으킬 수 있습니다. 새 QR 코드를 생성할 때마다 이전 객체 URL을 URL.revokeObjectURL()로 해제하여 메모리를 관리하는 것이 좋습니다. 아래 제안은 App 함수 내에 currentImageUrl 변수를 추가하여 이 문제를 해결합니다.
function App() {
const urlInput = document.getElementById('url-input');
const generateBtn = document.getElementById('generate-btn');
const qrCodeContainer = document.getElementById('qr-code-container');
const qrCodeImg = document.getElementById('qr-code-img');
const downloadBtn = document.getElementById('download-btn');
const errorMessage = document.getElementById('error-message');
const API_URL = 'https://api.qrserver.com/v1/create-qr-code/?size=256x256&data=';
let currentImageUrl = null;
const generateQRCode = async () => {
const data = urlInput.value.trim();
// Clear previous state
errorMessage.classList.add('hidden');
errorMessage.textContent = '';
qrCodeContainer.classList.add('hidden');
if (currentImageUrl) {
URL.revokeObjectURL(currentImageUrl);
}
if (!data) {
showError('Please enter a URL or text.');
return;
}
generateBtn.disabled = true;
generateBtn.textContent = 'Generating...';
try {
const qrUrl = `${API_URL}${encodeURIComponent(data)}`;
// We need to fetch the image to ensure it's valid before showing it.
// The API returns an image directly.
const response = await fetch(qrUrl);
if (!response.ok) {
throw new Error('Failed to generate QR code. Please try again.');
}
const imageBlob = await response.blob();
const imageUrl = URL.createObjectURL(imageBlob);
currentImageUrl = imageUrl;
qrCodeImg.src = imageUrl;
downloadBtn.href = imageUrl;
qrCodeImg.onload = () => {
qrCodeContainer.classList.remove('hidden');
};
} catch (error) {
const message = error instanceof Error ? error.message : 'An unknown error occurred.';
showError(message);
} finally {
generateBtn.disabled = false;
generateBtn.textContent = 'Generate';
}
};
const showError = (message) => {
errorMessage.textContent = message;
errorMessage.classList.remove('hidden');
};
generateBtn.addEventListener('click', generateQRCode);
urlInput.addEventListener('keydown', (event) => {
if (event.key === 'Enter') {
generateQRCode();
}
});
}

좀 더 자세히 설명해 주시겠어요? 저도 배우고 있고 궁금해요. 구글 번역이라 제가 잘 못하더라도 양해 부탁드립니다
