Day 53: CI/CD for React on AWS S3 & CloudFront (No Access Keys!) 🚀
Deploying React to S3 manually gets old fast. If you are still dragging and dropping folders into the AWS Console, it's time to stop.Today, I built a GitHub Actions pipeline that builds my React app, syncs it to S3, and clears the CloudFront cache automatically. Best part? Zero static AWS credentials.The WorkflowAssuming you already have an OIDC Identity Provider set up in AWS IAM (which you should, to avoid storing Access Keys in GitHub Secrets), here is the workflow I wrote today:YAMLname: Dep

Frontend Engineers Are Becoming AI Trainers
Frontend engineering is undergoing a quiet but fundamental transformation.For years, frontend developers focused on building interfaces, managing state, handling user interactions, and ensuring smooth user experiences. The responsibilities were clear: design components, connect APIs, manage data flow, and render UI efficiently.But the rise of AI-powered applications is changing this role in a significant way.Frontend engineers are no longer just building interfaces — they are increasingly shapin
What the React Compiler Quietly Skips
React Compiler 1.0 went stable in October 2025. Half the tutorials I saw declared useMemo dead. It's not — and on most existing codebases, the compiler will silently skip the components you most want it to optimize. The compiler handles one thingRe-render performance. It's a build-time plugin that analyzes your components and inserts memoization automatically, without you writing it.The genuinely useful part: it can memoize values in code paths after an early return, which manual useMemo ca
Building a Text Case Converter in React — 8 Transforms with Regex, From camelCase to SCREAMING_SNAKE_CASE
Text case conversion sounds trivial until you try to handle all the edge cases. Converting "hello world" to camelCase is easy. But what about converting XMLParser to snake_case? Or handling mixed input like "My API-Key_Value" correctly?Here's how the Text Case Converter at Ultimate Tools implements 8 case transforms in React using regex-based transformations. The 8 TransformsThe component exposes these functions, each accepting and updating a shared text state:const [text, setText] = useSta
What if: we have two same keys in Reactjs?
It is duythenights again! Great to have you back.If you’ve seen that yellow warning in your console: "Encountered two children with the same key," don't ignore it.This is not just a cosmetic console error; it is a fundamental logic failure that results in what I call "Reconciliation Chaos." To understand why this happens, we need to look at how React manages the relationship between your data and the physical DOM. The Core Problem: How React Logic BreaksTo see the disaster in action, let's
Why your React app feels slow (and how to fix it)
Everything seems fine… until it isn’t.You can have a React app that feels instant with a small number of users, and then suddenly it starts struggling as load grows.In most cases, the issue isn’t the server or network — it’s inefficient rendering on the client.The real gap between an “okay” app and a fast one is how predictable and controlled your renders are. What actually triggers re-rendersBefore trying to optimize anything, it’s important to understand what causes updates in React.A com

Things I Stopped Writing in React (And What Replaced Them)
Over the past year, I noticed I was deleting more code than I was writing. Not because I was cleaning up old mistakes, but because React had quietly started doing things I used to do myself.At first, I thought it was just me getting more comfortable with the codebase, but then I realized React itself had changed, and a lot of what I was writing by hand had a simpler, built-in way of doing it now.These are five of those patterns, which I was writing before, and what replaced them after React 19.
Why I Design in Figma Like I’m Already Writing the React Code
As a developer who spends half my day in Figma and the other half in VS Code, I’ve realized one thing: The biggest bottleneck in product development is a "non-technical" design. Most designers create beautiful layouts that are a nightmare to implement. As the founder of Loading IT Solutions, I’ve shifted my workflow to a "Code-First Design" approach. Here is how I bridge the gap: 1. Auto-Layout is just Flexbox I never design with floating elements. In Figma, I use Auto-Layout for everything. W
Why React Error Boundaries Are Still Class Components
If a child component throws during render, React can unmount the whole subtree beneath it. Related: React State Management Patterns—another area where the class-vs-hooks split shows up in practice.Without containment, one bad leaf can leave users staring at a blank page—the informal “white screen of death.” React error boundaries exist to catch rendering errors and show a fallback UI instead of tearing down the entire app.Most greenfield React code today is functional components and hooks.

React State Management Compared: Redux vs Zustand vs Jotai vs Valtio

Also in this series: Why React Error Boundaries Are Class Components: one of the few React APIs that still requires a class.That works until re-renders spike, boilerplate spreads, or onboarding slows new hires. The useful split is not “which logo is popular” but which architecture you are buying: a centralized store, an atomic graph, or a proxy snapshot model.This post compares Redux and Zustand (centralized), Jotai (atomi
