ARIA applied incorrectly often makes web pages less accessible rather than more. This article walks through the most common ARIA mistakes in real frontends, from redundant roles to misused aria-hidden and missing required states, and delivers a practical before-and-after audit for Magento and Hyvä projects.

Most TypeScript style guides end up as a long wiki page, written once and never read again. A style guide that actually works defines a clear scope, enforces rules automatically with ESLint and shows conventions through real examples instead of abstract prose.

React Hooks have revolutionized component development, but for many server-rendered projects Alpine.js is the better choice: less build tooling, no virtual DOM, direct HTML enhancement. This article uses concrete patterns to show where Alpine.js is fully sufficient and where React plays to its strengths.

The Date object is one of the oldest and most error-prone parts of JavaScript. The Temporal API breaks with all of its design flaws: immutable types, explicit time zone semantics, correct calendar arithmetic and a clear API, without external libraries like Moment.js or date-fns.

Running E2E suites against an unknown database state produces flaky tests instead of reliable results. This article shows how to put Magento stores into an exactly known state before every test run, through API calls, CLI commands, or direct SQL fixtures, and how to reset that state quickly between runs without seeding everything from scratch every time.

E-E-A-T signals were originally developed as an evaluation framework for human quality raters at Google, but they now measurably affect answer selection in generative AI search systems as well. Experience, Expertise, Authoritativeness and Trust increasingly help decide which source a language model cites when several topically similar pieces of content are available, and they can be deliberately strengthened through concrete, technically implementable signals.

The wishlist button is one of the most unassuming yet most frequently mismarked interaction elements in an online store: a heart icon flips its state on click without any visible change to the surrounding markup, and that silent status change is invisible to screen reader users without extra ARIA work. Applying the toggle button pattern with aria-pressed consistently, and actively announcing status changes, turns a purely visual switch into a traceable action, including while managing the wishlist itself.

For publishers, choosing correctly between Article, NewsArticle and BlogPosting directly affects visibility in Google News and Top Stories. Many newsrooms use the wrong schema type or leave out fields required for News eligibility without ever noticing. This article clarifies the differences, covers the fields needed for author and publisher linking, and explains how to find common validation errors with the Rich Results Test.

Loading data sounds trivial, until the first API request hangs in production, the loading state is unclear, or stale cache data shows the user a false picture of reality. Vue 3 and Nuxt provide mature primitives for data fetching that together cover caching, error handling and SSR compatibility.

is and where are usually introduced as a plain shortcut for long selector lists, yet their biggest value lies in specificity control. where() creates zero specificity for resets and design systems, is() inherits the highest specificity of its argument, without developers having to spell out every combination manually.
