Active Record Pattern
in Magento 2

Responsive Product Grid Patterns: CSS Grid for Magento Category Pages

Maxim Mironjuk - September 02, 2025

A responsive product grid pattern with auto-fill, minmax and aspect-ratio ensures product cards stay evenly distributed at every screen size, without maintaining a separate media query for every column count. This technique is the difference between a category grid that breaks at every new screen width and one that adapts by itself.

Injectable & Virtual Types
in Magento 2

Why can a Product object not be injected directly via the constructor, yet a ProductRepository can? The distinction between Injectable and Non-Injectable Objects is fundamental to Magento 2 DI. Virtual Types elegantly solve a common di.xml problem on top of that.

Code Review Checklist for Magento 2 Pull Requests

Maxim Mironjuk - September 01, 2025

A generic code review misses the traps that specifically cause production problems in Magento: misused preferences, broken public APIs, install scripts instead of schema. A Magento-specific code review checklist surfaces these risks systematically before they get merged.

Systematically Cleaning Up Magento Log and Report Tables

Maxim Mironjuk - September 01, 2025

Log tables like report_event, customer_visitor, and catalog_compare_item log visitor behavior and grow with every page view, often faster than any other table group in the store. Once you configure built-in log cleaning correctly and build custom scripts for tables without automatic cleanup, you keep the database lean without giving up important reporting data.

The free Magento Security Scan Tool automatically checks publicly reachable stores for known vulnerabilities, risky file permissions, and accidentally exposed sensitive files such as .git or .env files. This article shows how to register a store correctly, set up recurring scans, prioritize findings properly, and understand why the tool never replaces a real penetration test.

Understanding and Following Magento's Backward Compatibility Policy

Maxim Mironjuk - August 25, 2025

A Magento upgrade that suddenly tears apart your own modules almost always has the same root cause: somewhere in the code, a class was extended or overridden that Adobe never promised as a stable interface. Whoever understands what the @api tag means and why plugins are the safe extension method builds modules that survive Magento updates without nasty surprises.

Magento 2 · Caching

Full Page Cache
Find Hole Punches and Invalidate Selectively

The Full Page Cache is one of the biggest performance levers in Magento 2, but also a frequent source of errors. Anyone who wires dynamic content in the wrong way or invalidates the cache too bluntly loses hit rate, speed and often functional correctness as well.

Preparing Release Directories on the Server: shared, var, pub/media, app/etc

Maxim Mironjuk - August 24, 2025

Zero downtime deployments do not fail because of the pipeline, they fail because of a badly prepared server structure. If shared directories and symlinks are not set up correctly, every release either loses media files or loses the configuration.
