Advanced Patterns React Coming Soon

I wanted to give you a heads up about something I've been working on.

I've been building complex React applications for years, and I've learned there's a massive gap between tutorial level coding and real world development. Most courses show you fragments, I want to show you how professional-grade applications actually come together.

This course is my attempt to share the design patterns that transformed my own engineering approach. We'll dive deep into techniques that go way beyond typical tutorials:

• End-to-end type safety with tRPC

• Advanced React Query optimization

• Custom navigation with Tanstack Router

• Robust authentication workflows

• Dynamic filtering at scale

• UI design with Tailwind and shadcn/ui

What makes this different? We're building a full project together, not just isolated components. You'll see how these design patterns work in context, how they solve real problems, and why senior developers think about architecture the way they do.

⚡️ The Latest In React 

🔎 Under the Hood of React Query: A Deep Dive into Its Internal Mechanics
With over 6 million weekly downloads, @tanstack/react-query is super popular. From startups to Fortune 500 giants, it's become the tool for handling server state in React. Rohith Janardhan pulls back the curtain on why this library feels like magic. showing how features like smart caching, refetch-on-focus, and garbage collection actually work, complete with code, concepts, and a mini reimplementation.

🤏 How I Reduced My React Bundle Size by 30%
Your app was blazing fast… until it wasn’t. Builds drag, performance drops, and users start noticing. But you didn’t write anything “weird,” right? Chances are, your bundle size blew up. This post breaks down 7 legit ways to shrink it back down, with a real demo you can run and results you’ll actually feel.

🌊 Understanding Hydration Errors in React
If you’ve touched server-rendered React, you’ve seen this beast: “Hydration failed because the UI doesn’t match the server.” At first, it feels harmless. you dismiss it and move on. But should you? This post digs into hydration errors: what they are, when they matter, and walks you through building a simple React + Express SSR app to uncover what’s really going on.

😕 React Server Confusion
React is inescapable, maybe one day like the COBOL of the web. Even if you’re not a fan, odds are you’ll bump into it at some point in your dev life. And then comes react-server-dom-webpack—a package downloaded over half a million times, yet somehow still lacking proper docs. Want to use it with Vite? Be ready for some serious bundler gymnastics... This blog dives deep into React server confusion.

🧠 AI & General Programming

⬆️ Microsoft Copilots Big Upgrade
Microsoft’s Copilot Vision is getting a major upgrade, it can now see and interact with any app on your PC, not just Edge. From guiding you through Photoshop to adjusting your Minecraft settings, it’s aiming to be your full-time digital sidekick. It’s also getting “memory,” allowing it to remember personal details (opt-in, thankfully), which feels both helpful and a bit Black Mirror. Add in new features like real-time shopping and automated tasks, and Copilot is quickly becoming a lot more than just a chatbot.

🧪 Don't Mock Your Framework: Writing Tests You Won't Regret
Mocking your framework might feel like a shortcut, but it’s a trap. Tests become brittle, upgrades turn painful, and integration issues stay hidden until it’s too late. The rule is simple: don’t mock what you don’t own, a core principle from TDD veterans that’s more relevant than ever in today’s TypeScript-heavy world. Mocking React, Remix, or Next.js internals? That’s just borrowing trouble from your future self. Stick to mocking your own code, and let the framework do its job.

🚄 The Fifth Kind of Optimisation
In Laurence Tratt’s latest blog, he revisits his list of core optimisations and admits he missed a big one: parallelisation. While his original list covered algorithms, data structures, low-level systems, and precision trade-offs, he now argues that parallel work is too powerful to ignore, especially as modern workloads demand it. With LLMs thriving on "less precise" solutions, his updated view feels both timely and brutally honest.
