The Illusion of 100% Test Coverage
I've watched teams chase 100% and still ship bugs. Coverage proves code ran, not that it worked. Real safety comes from assertions that bite, weird inputs, mutation tests, and tough reviews. Treat coverage as a flashlight, not a finish line.
The Tyranny of Tiny Modules
Modularity is not a numbers game. A 300-line component with a clean flow beats ten shallow ones across folders. Barrels bloat bundles and hide cycles. Write for brains, not style cops: minimize hops, keep related logic close, abstract when it’s earned.
Cutting Redundant Data Fetches with React’s `cache` in React 19
React 19’s cache memoizes server calls per request. Wrap a fetch or DB query, call it from multiple server components, and React runs it once. Fewer duplicate hits, faster pages, consistent data. The cache clears after render. Use it in Next.js 15 with RSC.
TypeScript Soup: Taming an Unruly API
One tiny helper, big payoff. Use template literal types to infer base fields from `nameFr` style keys, then `getLocalized(locale, obj, fields)` returns exactly what you asked for. No copy-paste, no string concat, typos blocked, locales centralized, fallbacks handled.
Fresh vs. Next.js 15
I tried Fresh after another hydration bug. It shipped HTML, woke just the interactive islands, and my laptop sighed in relief. Next 15 felt heavier but battle-tested. My take: use Fresh for speed and clarity, Next when you need every plugin and playbook.
React 19’s New Hooks: Practical Relief or Added Complexity?
React 19: use() for async data, form actions with useFormStatus/useActionState, useOptimistic for snappy updates, and async transitions. Fewer effects and form libs—cleaner patterns for forms, fetching, and UX.
When Shiny Apps Still Suck
A sleek UI can mask deep flaws. The aesthetic-usability effect means pretty products get the benefit of the doubt, but looks don’t equal quality. Real value comes from speed, clarity, and reliability. Shiny exteriors fade fast if the engine underneath is slow, brittle, or confusing.
Are React Server Components Improving Your Apps?
React Server Components (RSCs) can deliver real performance wins. One team rebuilt their Next.js site with RSCs and achieved a 62 % drop in JavaScript bundle size and a 63 % boost in Google’s Speed Index. Less client‑side React logic means faster first paints.
You’re NOT Big Tech
You’re not Netflix. Nor Amazon, Facebook, or Google—and yet many developers build systems as if you are. We spin up microservices, multi-region setups, and abstraction layers for users who don’t exist. We solve imaginary problems while missing the real ones.
Why Continuous Integration Is Killing Your Productivity Instead of Helping
Continuous Integration promised faster feedback and fewer integration headaches. But when misapplied, it turns into a grind—slow, flaky pipelines that stall your flow and leave you staring at progress bars or midnight build failures. The very tool meant to help can end up draining your productivity.
The Cost of Switching Frameworks Every Year That No One Wants to Admit
Frontend development moves fast. Every few months a new framework entices us. We rebuild our app in React, then Vue, then Svelte or Solid. Yet beneath the fun of chasing the newest, there are hidden costs—technical overhead, morale hits, loss of institutional knowledge, hiring headaches.
ESM vs CommonJS: History, Differences, and the Big Shift
You’ve likely seen multiple JavaScript module systems. Node.js built on CommonJS with require and module.exports. Browsers adopted ES modules using import and export. Today the ecosystem is shifting toward ESM, but CommonJS still holds strong in many projects.
