Building Custom AI Agents With JavaScript and React — From Prototype to Production

Every AI agent tutorial ends the same way.The agent completes a task. The output looks correct. The tutorial ends.

The same Rust gave two different answers, and neither matched JavaScript

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry. The setupI was porting TinyColor, a fifteen-year-old JavaScript colour library, to Rust. The rule I set myself was that the original test suite had to pass unmodified. Not a translation of it. The actual file, byte for byte, sha256-pinned, loading my Rust instead of the JavaScript.That works because upstream's test file loads the library on exactly one line:const tinycolor = require("./tinycolor.js");So I comp

How I Redesigned a Legacy Website Without Breaking Production

Redesigning a website from scratch sounds exciting.You get a clean codebase, modern components, better UX, and the opportunity to finally remove all those hacks that have been sitting in production for years.But there is one problem:The old website is already working.Thousands of users might depend on it. Search engines already know its URLs. Analytics are configured. Marketing links are everywhere. APIs expect a particular structure. And somewhere in the codebase, there is probably a !important

Unblocking the UI: Web Workers in Next.js ⚡

The Vulnerability of the Single ThreadJavaScript was originally designed in 1995 to do very simple things: validate forms, create alert boxes, and manipulate the DOM. To keep the language simple and avoid complex concurrency issues, its creator made a fundamental architectural decision: JavaScript would be strictly single-threaded. This means that inside the browser, the code that fetches data, the code that runs your business logic, and the code that literally paints the pixels onto the user's

TypeScript 6.0 Strict Function Types: Why Contravariance Breaks Your Existing Callbacks

TypeScript 6.0 Strict Function Types: Why Contravariance Breaks Your Existing CallbacksThis article was written with the assistance of AI, under human supervision and review.Most TypeScript migration failures stem from a single misunderstood compiler flag: strictFunctionTypes. The pattern that breaks production is deceptively simple—a callback that accepts a base type where the consumer expects a derived type. TypeScript 6.0 enables strict mode by default, which means codebases that never

Door Handles Are the Original User Interface: The Engineering Behind Better Hardware

Ever pushed open a door and immediately felt that something was right?That experience usually isn't accidental. While we tend to focus on the door, colour, finish, or style, the hardware plays a major role in how a door feels in everyday use.As a developer, I think about door handles much like I think about UI: small design decisions can dramatically change the user experience.Lever Length Is More Than a Design ChoiceOne of the most important details is lever length.A longer lever can provide gr

Restoring a Period Fireplace: A Guide to the Carron Valentine Cast Iron Fireplace

Stop Copy-Pasting PDF Invoices: A Faster Way to Convert Invoice Data to CSV

Dealing with a mountain of PDF invoices is a familiar problem for developers, accountants, and finance teams.The data you need may be sitting inside dozens—or hundreds—of PDF documents, but getting that information into a database, spreadsheet, or dashboard can become surprisingly time-consuming.Copy-pasting tables from PDFs into Excel often creates another problem: broken formatting, misplaced columns, incorrect numbers, and hours of manual cleanup.The Traditional Developer ApproachIf you're co

I Built the Same Commerce App in Kudzu, Astro, React Router, TanStack Start, and Next.js

In my previous post, I introduced Kudzu, a compiler-first framework that turns a statically analyzable subset of React-shaped TSX into static HTML and route-specific JavaScript without shipping React, a virtual DOM, or a hydration runtime.That raises an obvious question:What happens when you move beyond counters and small demos?So I built the same commerce application five times:KudzuAstro + React islandsReact RouterTanStack StartNext.js App RouterThe goal wasn't to create a synthetic benchmark
