Why “Good Enough” isn't enough for a scalable Feed. Most side projects start with a simple goal. For me, it was just fetching a backend feed and displaying it on a screen. But as soon as I hit "Refresh," I realized a feed isn't just a list of data, it’s a living ecosystem of state. The Pivot: What started as a simple GET request evolved into a deep dive into 4-Layer Architecture. I didn't just want to show posts; I wanted a system where following a user, accepting a request, and updating a sidebar felt instantaneous and "true" to the database. The Challenges (The parts that didn’t make the highlight reel): ▪️The Infinite Loop Trap: Early on, I triggered nearly 1,000 recursive errors. Using a global context meant that every time I updated a follower count, my entire navigation re-rendered, triggering another fetch. ▪️State Disconnect: There’s a specific frustration in clicking "Accept Request" and seeing the notification badge stay stuck at '1'. Solving this meant rethinking how the Service Layer communicates with the Context Layer. ▪️The "Self" Filter: It sounds simple, but ensuring a user doesn't get suggested to follow themselves requires a tight sync between the Auth state and the Suggestion engine. Why the 4-Layer approach? I moved toward a strict separation between API Services, Custom Hooks, and Context Providers. The Result: A UI that doesn't just "fetch", it synchronizes. When you confirm a follower in the Navbar, the Sidebar stats update in real-time without a page reload. Building the "feature" was easy. Building the flow that handles data consistency across three different components was where the real learning happened.
