BEM, Utility First and CSS Modules Compared in 2026

Maxim Mironjuk - February 10, 2026

Choosing the right CSS methodology determines maintainability, onboarding time and refactoring cost for years to come. BEM, Utility First and CSS Modules solve the same core problem, naming collisions and uncontrolled cascade, with fundamentally different trade offs in readability, build complexity and team discipline.

Styling Modal Dialogs with the Native dialog Element

Maxim Mironjuk - February 08, 2026

The dialog element ships focus management, escape handling and a real backdrop straight from the browser. With Tailwind CSS and a bit of Alpine.js it becomes a production ready modal system that needs no focus trap library and stays fully accessible.

Building Custom Refs in Vue 3: customRef, track and trigger

Maxim Mironjuk - February 07, 2026

A Custom Ref gives full control over dependency tracking and update triggering. Once you understand the customRef API, you can encapsulate debounce, validation, storage synchronization and other patterns as a clean, reusable reactive primitive instead of wiring them up again in every component.

Designing Agent Pipelines for Complex Tasks

Maxim Mironjuk - February 02, 2026

Complex development tasks are rarely solved reliably with a single prompt. An agent pipeline breaks such a task down into clearly separated stages with defined data flow, built in quality gates and regulated error handling, so every stage stays traceable and errors do not silently propagate all the way to the end.

GraphQL Multi-Tenancy: Building Tenant-Aware Schemas and Resolvers

Maxim Mironjuk - January 25, 2026

A shared GraphQL API for multiple tenants saves infrastructure, but carries a real risk: one forgotten tenant filter in a resolver, and tenant A sees tenant B's data. Building tenant isolation systematically instead of ad hoc avoids exactly that scenario.

Migrating from Redux to Zustand: Leaner State Management

Maxim Mironjuk - January 23, 2026

Redux still solves valid problems today, but in many projects it buries the actual business logic under boilerplate. Whoever migrates from Redux to Zustand step by step replaces reducers, actions and middleware slice by slice, without rewriting the app in a risky single pass.

Polymorphic Associations in SQL Design

Maxim Mironjuk - January 23, 2026

A Polymorphic Association promises a single comments table for posts, photos, and videos at once, but the generic foreign key behind it breaks the database's referential integrity. This post shows how the classic type-plus-id pattern emerges, why it leads to orphaned rows, and which three alternatives solve the same problem without giving up foreign key constraints.

Implementing the Observer Pattern in JavaScript: Loosely Coupled Event Systems

Maxim Mironjuk - January 21, 2026

The Observer Pattern decouples a state holder from the pieces of code that need to react to its changes, with no direct references between them at all. From a minimal subject class through the native EventTarget interface to WeakRef-based cleanup, this article shows how to implement the Observer Pattern robustly in plain JavaScript.

Building a Form Wizard Step Indicator

Maxim Mironjuk - January 16, 2026

A good step indicator always shows where you are inside a form wizard, which steps are already done and how many are still to come. With Tailwind CSS and Alpine.js this indicator can be built consistently from a few reusable states, instead of maintaining separate markup for every step.

Functional Error Handling in PHP with Maybe and Either

Maxim Mironjuk - January 16, 2026

Maybe and Either make an error state part of the return type, instead of hiding it implicitly behind null or a thrown exception. In PHP 8.4 both types can be fully rebuilt with readonly classes and enums, without any external library.
