Indexer Dependency Management in Magento 2: Controlling Invalidation Order

Maxim Mironjuk - November 25, 2025

Once a custom indexer builds on the results of another, clean indexer dependency management decides whether the data ends up consistent or whether a downstream indexer regularly computes on stale intermediate results without anyone noticing the mistake right away.

Migrating Procedural PHP to Object-Oriented Code

Maxim Mironjuk - November 16, 2025

Many grown PHP projects consist of hundreds of free functions loosely held together by include files. This article shows how to migrate such procedural codebases to object-oriented PHP step by step, using recognizable extraction patterns instead of a risky full rewrite.

Custom Payment Method Integration in the Magento 2 Checkout

Maxim Mironjuk - November 14, 2025

A custom payment method integration in Magento 2 is not a simple form with account details, it is a complete gateway connection with authorization, capture, cancellation and asynchronous status updates. The Payment Gateway Command Pattern structures these building blocks so an external payment provider can be connected without any core overrides.

Object Cloning in PHP: Mastering __clone, Deep Copy and Shallow Copy

Maxim Mironjuk - November 12, 2025

The clone keyword in PHP produces only a shallow copy by default, nested objects remain shared. With the __clone magic method, object cloning can be extended deliberately into a deep copy, including readonly properties and the classic Prototype pattern as a creation strategy.

Holy Grail Layout With Modern CSS: Grid Instead of Floats and Tables

Maxim Mironjuk - November 09, 2025

The Holy Grail Layout of header, two side columns, main content and footer was long considered one of the hardest CSS problems around. With CSS Grid, template areas, gap and subgrid, the same layout can be built today in a handful of clearly readable lines, with no float hacks, no tables and no fragile absolute positioning.

Alpine.js Store: Global State Without Vuex or Redux

Maxim Mironjuk - November 09, 2025

Global state in large JavaScript applications quickly leads teams toward Vuex, Redux or Zustand. In Alpine.js projects that is usually overkill. Alpine.store delivers reactive global state that is readable and writable from any component, with no build step, no boilerplate and no new concepts to learn.

Theming System with CSS Variables in React

Maxim Mironjuk - November 06, 2025

A theming system with CSS variables stores design tokens as native custom properties in the browser instead of recomputing them via JavaScript on every render. The result is a theme switch without re rendering components, a smaller bundle size, and an approach that works independently of the chosen CSS strategy.

Using Custom Events as a Component Bus | Alpine.js

Maxim Mironjuk - November 02, 2025

Custom events are the lightweight way to let independent Alpine.js components communicate without setting up a central store. With $dispatch and matching event listeners, a component bus emerges where sender and receiver don't need to know about each other, as long as both agree on the same event name and payload structure.

Understanding Eventual Consistency in Practice

Maxim Mironjuk - October 27, 2025

Eventual consistency is not a compromise for poorly built systems but a deliberate consequence of the CAP theorem in every distributed system, including read replicas in relational databases. Whoever concretely understands consistency models, conflict resolution, and replication lag makes better decisions about where a short delay is acceptable and where it is not.

Symfony DI: Decorators and Compiler Passes

Maxim Mironjuk - October 25, 2025

The Symfony dependency injection container is more than a service locator. Decorators let you extend third-party services without touching their code. Compiler passes manipulate the container at build time and automate configurations that would otherwise have to be maintained by hand.
