Depende do que você tá tentando otimizar, onde que o projeto tá publicado. Pra otimizar NextJS eu gosto de usar o ReactDevTools (extensão do browser) e rodar o Profiler, ele acusa qual componente tá demorando mais ou renderizando mais do que deveria.

Aarathy Muraleedharan from Keyvalue Software Systems just wrapped a brilliant session on React DevTools AI. Smarter code suggestions, faster debugging, the future of React dev is here. #ReactIndia2025 #ReactDevTools

"ReactDevTools 外すと 10点上がることある" とのこと。やばい。#LAPRAS公開パフォーマンスチューニング

Soon, you'll be able to toggle component render highlighting directly from the top bar. Small quality-of-life improvement that makes a difference! Still searching for an icon for it 🤔 #ReactDevTools

Congrats Alex I’m sure it was amazing! Would have loved to have been there!

It was my pleasure to dive with the audience into some intensive #ReactNative #performance debugging! 🤓 We've gone through: ⚛️ @ReactDevTools 🌐 Chrome JS profiler 🤖 Android Studio 🍎 Xcode instruments 🔦 Flashlight ⚛️ React compiler All that in a single morning 🔥

🔦Measure with Flashlight 📈Analyze (usually with ReactDevTools if Flashlight revealed issues on JS side, or Android Studio if native side) ✅ Fix issue and measure again 🤔 Problem-solve to prevent issue from reoccurring There might be something at @RNLConf on the subject 😇

day 4—145 out of 695 tictactoe ✅ Refresher on— - state management - styling techniques - debugging using error messages, debugger, strictmode, reactDevTools ext - refs and portals ⏳ currently working on investment calculator site #buildinpublic #100DaysOfCode #react #reactjs

This looks like a neat tool to try out when comparing @ReactDevTools profiling 👏 whether you're measuring #React or #ReactNative #performance 🔥

🛠️ Profile and Measure: Use React DevTools and performance profiling tools to identify bottlenecks. Measure before optimizing to focus efforts effectively. 📊🔍 #ReactDevTools #Optimization

💡3 key takeaways from #Frontkon by @Frontendisti that we recently attended 1️⃣ Let's start with a general tip. At any conference, prepare (and book if possible) things you want to see in advance. We can't stress this one enough. If you prefer the hands-on ones focus on anything labeled as a workshop, practical demonstration, tips, and tricks, and so on but get ready to really deep dive and that you will manage only one or two. If you are there for inspiration fireside chats, panel discussions, lightning talks, etc. are your go-to sessions. On the other hand, you can visit a lot of these within just one day. 2️⃣ Tips and tricks in #React by Jakub Miškech from Outreach. We primarily learned more about #ReactDevTools and how to utilize them for code optimization using #useMemo, #useCallback, and #useContext. 3️⃣ We also realized that we don't have to use powerful #frameworks every time and that the future might be pure #CSS and #HTML.

Just had a breakthrough debugging session with React DevTools. It's an absolute lifesaver for inspecting component hierarchies, examining props and state, and pinpointing performance bottlenecks. #ReactDevTools #DebuggingNinja

The order of the debugging tools I use daily at work in frontend: @ReactDevTools ➡️ @ChromeDevTools ➡️ console.log (if nothing works!) This order has saved a lot of precious debugging time 💪⏰ #FrontEndDeveloper #Reactjs #LifeatRedHat

Flexbox Gap, la feature que tout dev UI demandait 😍

Such a fantastic release! 🥳 Including beautiful things like - TS by default - New arch build times considerably lowered less boilerplate code - new @ReactDevTools features - Hermes JSON.parse perf improvement ...and many others! Shout-out to all the contributors! 👏👏

普段書いてることはもちろん大事なんだけどそれだけじゃだめで、ReactDevToolsのHighlight updates when components renderを入れて何がだめなのか考えながら書くっていうのと、ja.reactjs.org/docs/lifting-… あたりを読みまくるのが大事な感じがする

My @react_native_eu talk is live on @callstackio YT channel!📺 We'll debunk 6 common #performance issues on a sample #ReactNative app (➡️ github.com/Almouro/test-app-…) ...using the power of @ReactDevTools, the JS profiler and Android Studio 🚀 youtu.be/3ieKK27lyxA
