ReactJs Performance ~ State Management~

・The choice of state management can have a dramatic effect on React performance, but most comparisons focus on developer experience rather than runtime characteristics.Having implemented Context, Redux, Zustand and Jotai in production apps, the following factors were found to be important: re-render frequency, serialisation overhead and selector performance. Each solution balances these factors differently.ToolMy ImpressionTrade-offGood Use CaseContext APISimple but limited at scaleRe-renders ca

Building an Unshielded Token dApp with UI on Midnight

Building an Unshielded Token dApp with UI on MidnightMidnight is best known for its privacy features, but not everything needs to be shielded. Unshielded tokens are perfect when you want on-chain verifiability without hiding transfer amounts—think public governance tokens, loyalty points, or demo applications. In this tutorial, we'll build a complete unshielded token dApp: a Compact smart contract, TypeScript integration, and a React frontend with wallet connection, mint, transfer, and bal

Introduction to React: A Beginner’s Guide

IntroductionReact is a popular JavaScript library used for building user interfaces, especially for single-page applications (SPAs). It was developed and maintained by Meta (formerly Facebook) and has become one of the most widely used tools among developers.When building web applications, you’ll often hear two terms: MPA (Multi-Page Application) and SPA (Single-Page Application). They represent different ways a website loads and updates content.What is an MPA (Multi-Page Application)?An

How I Optimized a React App from Slow to Lightning Fast (Real Performance Guide)

Most React tutorials focus on building apps. Very few teach you how to fix performance issues which is exactly what companies care about.In this article, I’ll walk through how I optimized a React app that was lagging badly and reduced load time significantly.🐢 The ProblemThe app had:Slow initial loadUnnecessary re-rendersLarge bundle sizePoor user experience on low-end devices✅ Step 1: Identifying the BottleneckBefore optimizing, I used:React DevTools ProfilerChrome Performance tabI discovered:C

I let Claude write my React compiler. I only reviewed the tests.

Open the React DevTools "highlight updates" panel on any React app you've ever worked on. Count the flashes. You've done this before, probably in an interview, probably while defending a useCallback. That counting habit is a React-specific anxiety, not a universal one — and the reason matters less for this post than what I did about it.I spent about a month building a thin wrapper around an existing state library (Legend-State) that tries to compile that anxiety away. The piece I want to write a

Multi-Stage Docker Builds: How I Cut a React Image from 760MB to 94MB

I built two Docker images for the same React app this week.One was 760MB. The other was 94MB. Both loaded the exact same website in the browser.That 87.6% difference is the story of this post. The SetupThis is Week 14 of my DevOps Micro Internship. The project: containerize a React app two ways, compare the results, and explain what changed and why it matters.I am running everything on an Azure VM (Ubuntu 24.04 LTS) with Docker auto-installed via cloud-init.The React app: https://github.com

React 19 use() Hook in Production: Suspense Data Fetching Without useEffect

The use() hook landed in React 19 and immediately changed how I think about data fetching. Not because it's magic — but because it finally makes Suspense-based data fetching feel like something you'd actually ship to production.Most articles show you use(promise) inside a toy component and call it a day. This one covers what happens when real users hit your app: race conditions, error boundary placement, streaming with RSC, caching strategies, and the gotchas that will bite you if you're not pay

You don’t need to dual-boot anymore, there’s a better way to try another OS

I'm a Windows user, and I'm no stranger to dual-booting. It was actually my first real introduction to Linux. Like a lot of people, I carved out a partition, installed a second OS, and got that satisfying moment of choosing which OS to boot into at startup. At the time, it felt like the right way to do it if you wanted the full experience.
