So I built it.</p> <h2> 🚀 Introducing 한눈IT (HanunIT) </h2> <p><strong>한눈IT</strong> means "IT at a glance" in Korean. It's a content aggregation platform that collects, summarizes, and serves the latest IT articles and videos in a clean reading experience.</p> <p>🔗 <a href="https://hanun-it.com" rel="noopener noreferrer">hanun-it.com</a></p> <h2> ✨ Key Features </h2> <h3> 📰 Article Aggregation </h3> <p>Continuously collects articles from 30+ sources via RSS feeds. New content flows in throughout the day — no manual curation needed.</p> <h3> 📝 AI-Powered Summaries </h3> <p>Every article comes with a concise summary. Scan dozens of articles in minutes and deep-dive only into what matters to you.</p> <h3> 🌐 Translated Articles </h3> <p>International tech articles are auto-translated into Korean, bridging the language gap for Korean-speaking developers.</p> <h3> 🎬 Tech Video Curation </h3> <p>Not just text — curated YouTube tech videos are collected alongside written articles. Switch between reading and watching depending on your mood.</p> <h3> 💬 Community Features </h3> <p>Comment on articles, like your favorites, and join discussions with other developers.</p> <h3> 📧 Newsletter </h3> <p>Subscribe to a weekly digest and get the best articles delivered to your inbox.</p> <h2> 🛠️ Tech Stack </h2> <p>Here's what's under the hood:</p> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Layer</th> <th>Tech</th> </tr> </thead> <tbody> <tr> <td>Framework</td> <td>Next.js 15 (App Router, Turbopack)</td> </tr> <tr> <td>Language</td> <td>TypeScript</td> </tr> <tr> <td>Database</td> <td>Supabase (PostgreSQL + RLS)</td> </tr> <tr> <td>Auth</td> <td>Supabase Auth</td> </tr> <tr> <td>State</td> <td>TanStack Query + Zustand</td> </tr> <tr> <td>Styling</td> <td>Tailwind CSS + Shadcn UI</td> </tr> <tr> <td>Deployment</td> <td>Vercel</td> </tr> <tr> <td>Analytics</td> <td>Vercel Analytics</td> </tr> </tbody> </table></div> <h2> 📐 Architecture Highlights </h2> <p>A few technical decisions I'm happy with:</p> <p><strong>Server-side rendering with caching</strong> — Article pages use <code>revalidate = 300</code> for ISR. API routes return <code>s-maxage=300, stale-while-revalidate=600</code> headers. Fast initial loads without hitting the DB every time.</p> <p><strong>Parallel data fetching</strong> — Article detail pages fire multiple Supabase queries with <code>Promise.allSettled</code> instead of sequential awaits. Shaved ~40% off load times.</p> <p><strong>Smart client caching</strong> — TanStack Query with 5-minute stale time and 30-minute GC. Users navigating between pages almost never see a loading spinner.</p> <p><strong>Per-request deduplication</strong> — Used <code>React.cache()</code> for article fetches in server components, so <code>generateMetadata</code> and the page component share the same data without duplicate DB calls.</p> <h2> 📸 Screenshots </h2> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fw8aqr0x1hrs4n5g84yl1.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fw8aqr0x1hrs4n5g84yl1.png" alt=" " width="800" height="566"></a></p> <h2> 🤷 What I Learned </h2> <ol> <li> <strong>RSS feeds are messy</strong> — Every source has a slightly different format. Spent more time on parsing edge cases than I expected.</li> <li> <strong>Supabase RLS is powerful but tricky</strong> — Row Level Security policies need careful planning upfront. Debugging permission errors is not fun.</li> <li> <strong>Next.js 15 App Router is great</strong> — Server components + streaming + ISR is a solid combo for content-heavy sites.</li> </ol> <h2> 🙏 Feedback Welcome </h2> <p>I'd love to hear:</p> <ul> <li>What IT sources would you want to see added?</li> <li>Any UX improvements you'd suggest?</li> <li>Would you use something like this for your local tech ecosystem?</li> </ul> <p>Thanks for reading!
