Building a Real-Time Word Counter in React — Unicode-Safe Splitting, Reading Time, and useRef for Instant Updates

A word counter seems trivial — split on spaces, count the parts. But accurate counting across Unicode text, real-time performance without re-renders on every keystroke, and reading time estimation all have implementation details worth getting right.Here's how the Word Counter at Ultimate Tools is built. Counting Words: The Right SplitThe naive approach:const count = text.split(' ').length;This breaks immediately on leading/trailing spaces, multiple consecutive spaces, newlines, and tabs — a

ShadCN UI in 2026: Why I Stopped Installing Component Libraries and Started Owning My Components

I've installed Chakra UI, MUI, Mantine, Radix, and Headless UI on different projects over the years. They all have the same problem: eventually you hit a wall where the library's opinion conflicts with yours, and you start writing overrides.ShadCN changed how I think about this. It's not a library you install — it's a code generator. When you run npx shadcn-ui@latest add button, it copies the component source into your project. You own it. No dependency to update, no fighting with CSS-in-JS over

How I Built a Tinder-Style Group Decision App with React Native and Firebase

My wife and I have a problem (no, not THAT kind of problem). It's the same problem every couple has: nobody can decide where to eat. Or what movie to watch. Or what show to binge next. The conversation follows a depressingly predictable script — "I don't care, what do you want?" repeated ad infinitum until someone either picks something out of frustration or you just stay home.So I built an app to solve it. WhaTo lets a group of up to 8 people join a session with a 4-letter code, swipe through o

Building Minesweeper in React — BFS Flood Fill, Safe First Click, and Responsive Scale-to-Fit

Minesweeper looks trivial to implement until you actually start. Then you run into: guaranteed safe first click, the flood-fill cascade that reveals large empty regions, and the scaling problem — the board needs to fit a phone screen without the cells getting unusably tiny.Here's how I built Minesweeper in React with all three solved properly. Board RepresentationEach cell is a plain object:interface Cell { isMine: boolean isRevealed: boolean isFlagged: boolean adjacentMines: number //

Front-End &amp; Struggles

I didn’t have much frontend experience. This post covers the struggles I ran into. Starting Point: React + TypeScript + Plain CSSReact with TypeScript felt like the obvious choice — popular, good ecosystem, type safety. I started writing plain CSS modules for styling. Full control, right?The problem wasn't the code. It was that I had no design vision. I'd write a component, look at it, and know it looked bad but not know how to fix it. What colors? How much padding? How should this align? I

tRPC v11 + Next.js App Router: End-to-End Type Safety Without the Boilerplate

I spent two days last year fighting tRPC v10 with the Next.js App Router. Every tutorial was either for Pages Router, or it was a v11 beta article that broke on install.Now that v11 is stable, the integration is genuinely good. Here's exactly how I set it up — no ceremony, just the patterns that work. Why tRPC Still Makes Sense in 2026Server Actions solved a lot. But they're one-way: client calls server, server returns. tRPC gives you a proper API layer with:Full TypeScript inference end-to

SaaS Billing in React Server Components: Stripe + Supabase Without a Single `useEffect`

Stripe billing is one of those features that turns into a mess fast. You end up with billing state in React context, useEffect calls to check subscription status, half the data on the client, the other half on the server, and no clear place to put anything.React Server Components fix this. Billing state is server state. It belongs on the server.Here's how I rebuilt the billing layer for a production SaaS using RSC + Stripe Meters + Supabase with zero client-side billing logic.

Next.js 15 + Claude API Streaming: Build a Real-Time AI Chat Interface From Scratch

That's fine until something breaks and you don't know why.This guide wires Claude's streaming API directly into Next.js 15's App Router with zero AI SDK dependency. By the end you'll have a production-quality streaming chat with proper backpressure, error handling, and a React UI that doesn't flash or stutter.

The Role of Fiber in React Rendering (Part 2): Buffers, Hooks, Lanes, and the Commit

In Part 1, we opened up React's Fiber engine and looked at the basics: what a Fiber node is, how the linked list tree is wired with child/sibling/return pointers, how the two-phase walk (beginWork down, completeWork up) processes every component, and how reconciliation diffs old Fibers against new elements.Now we go deeper. This part covers the systems that make Fiber actually powerful: double buffering, effect flags, priority lanes, where your hooks live, and the three sub-phases of the commit.
