New post 📢: how I used Claude Code to build a Chrome extension and an n8n workflow that automates my AI tech watch sharing. The whole thing in about 30 minutes. www.56kode.com/posts/ai-pow...

🔥 Just discovered rtk-ai.app, a game-changer for Claude Code users! It filters shell output noise before it reaches your AI: ✅ Fewer tokens = lower cost ✅ Longer sessions, no context reset needed ✅ More focused agent, less distraction Thanks to Florian Bruniaux

Why I migrated from #Cursor to #ClaudeCode (and why you should too). ⚡️ I stopped typing code and started supervising agents in the terminal. The productivity gain is real. 🤖 Read my full honest feedback here: 👉 www.56kode.com/posts/moving... #ai #agent #opus

Stop cleaning dead code manually! 🛑 Discover a safe workflow combining Knip to find unused exports and an AI agent to verify and remove them without breaking production. 🤖 👉 56kode.com/posts/clean-... #TypeScript #ts #ai #cursor #claudecode

Last week I asked #Gemini for a summary but forgot the URL. It gave me a summary anyway. Apparently, prompt engineering is obsolete; we’re moving straight to telepathic engineering. Or just pure hallucinations. 😅🔮#AI

Forget “Reasoning Avg” and “Coding Avg”. My only #AI benchmark: insults per day. #Gemini 3 Pro & Claude #Opus? So good I sometimes go 24h without calling them names. That’s basically AGI in my house.

After a new wave of discussion about CustomEvent vs Event subclasses, I wrote a new blog post on the topic: TL;DR: Subclass Event instead of using CustomEvent 😎 justinfagnani.com/2025/06/25/s...

Our Vitest tests took 22s to start. Now? 4 seconds. 🚀 How Gemini 3 Pro identified "God Modules" killing our performance and automated the fix—saving us 15 min per CI run. 👉 www.56kode.com/posts/how-ge... #Vitest #CI #react #reactjs

🚀 Debug web apps directly from #Cursor #IDE with Browser-Tools #MCP! ⚡ 🔹 Console logs analysis 🔹 Network requests inspection 🔹 AI-powered debugging 👉 www.56kode.com/posts/connec... #CursorIDE #AI #debug #chrome

Back from vacation ✈️ and straight into action! I let AI handle a full dependency migration on my Astro blog: React 19, Astro 5 Content Layer, Tailwind… all automated ⚡ Curious how it went? 👉 www.56kode.com/posts/automa... #Astro #AI #cursor #cursorAI

Lost in your codebase? 🤯 Cursor's screenshot search feature is a game-changer! Just paste a UI screenshot and it finds the corresponding file for you. Saves so much time! #Cursor

AI agent stuck? 😫 Pro tip: Just open a new chat and restart! Often fixes the bug and gets things running smoothly again. #AI

🚀 New article: Level Up #React - Mastering Context API 🔍 Learn how React's Context API really works under the hood, what’s new in React 19, and when to use it vs Zustand or Redux. 📉 Avoid unnecessary re-renders with proven optimization tips. 📖 Read → www.56kode.com/posts/level-...

🧪 What if your tests... were being tested too? A high code coverage doesn’t mean your app is bug-free. It just means your code was executed by tests — not that it was really verified. Let me show you something better: mutation testing 👇 #testing #jest #vitest #js #ts

AI tools like ChatGPT or Claude write way better code with #TypeScript 🤖🧠 Your types give the AI context 👇 Well-typed code = better suggestions, safer refactors, fewer bugs. TypeScript isn’t a nice-to-have. It’s your AI co-pilot’s map 🗺️ #ts #ai #cursor #windsurf

Want better answers from #AI? 🤔 First, ask what info it’s missing to help you better. ✍️ Then, ask it to rewrite your prompt for clarity. You don’t need to be perfect — just collaborate smart 🤖✨ #chatpgt #claudeai #claude #gemini #deepseek

Your React.memo component keeps re-rendering? Check the children. JSX passed inline is recreated every render → breaks memo. ✅ Solution: memoize children with useMemo, or don’t memoize at all if it’s not worth it. Code ⬇️
