The Strategy pattern defines a family of algorithms, encapsulates each one and makes them interchangeable. In Magento 2 it shows up everywhere: tax calculation, shipping methods, price rules, payment methods, all of them rely on Strategy.

When search in the store returns wrong or missing results, guessing rarely helps. Systematic search debugging starts by capturing the actual Elasticsearch query Magento generates, running that query directly against the cluster, and reliably separating whether the problem lies in Magento's logic or in the Elasticsearch index itself. This article walks through the methodology step by step.

Copying Luma's newsletter widget straight into a Hyvä theme collides with the strict Content Security Policy and produces a form that silently fails in the browser. A clean newsletter integration instead needs registerInlineScript(), a lean Alpine.js component with fetch(), a properly communicated double opt-in flow, and a server-validated GDPR consent checkbox, placed cleanly via layout XML in the footer, checkout success page and CMS block.

A bug that stubbornly refuses to reproduce locally but occurs regularly in production is one of the most frustrating problems in day-to-day Magento work. With systematic scoping, safe remote debugging and structured logging, even the most stubborn production-only bug becomes tractable.

Magento plugins and observers are powerful extension points, but their tight coupling to the Magento ObjectManager makes them hard to test. With the right refactoring approach, the core logic of any plugin or observer can be extracted and tested in isolation with PHPUnit, entirely without a Magento bootstrap.

Catalog Price Rules and Cart Price Rules solve different problems in Magento 2, yet they are frequently confused or combined incorrectly on real projects. Understanding the indexing, the point of application, and the customer group logic of both rule systems prevents double discounting and unnecessary reindex overhead. This article lays out the practical decision tree: when a Catalog Price Rule and when a Cart Price Rule is the right tool.

Editors keep adding images, sliders and nested containers to Page Builder pages over months, without performance staying in view. With targeted lazy loading, critical CSS for the visible area and consistent image optimization, Page Builder content stays fast and Core Web Vitals capable even as it grows.

When conversion has stagnated or slowly declined for months without an obvious cause, more guessing rarely helps, a systematic e-commerce audit does. Unlike a spot check for a single bug, an audit reviews the store along clearly defined areas, from technical SEO through performance and conversion to security, and ends with a prioritized action list instead of a loose collection of observations. This article shows how such an audit actually runs, which review areas need to come together, and how to prioritize the findings sensibly.

Claude Code can sketch a new Hyva template in seconds, but only with the right project conventions as context does it produce genuinely usable code. This article shows how to scaffold a phtml template with a matching view model, generate Alpine.js components that stay CSP compliant, and verify AI-suggested Tailwind classes against the actual design system before they reach production.

Redis handles two fundamentally different jobs in Magento 2: write-heavy session storage and read-heavy caching, often on the same server without any clean separation. This article shows how to calculate the memory needs for Redis sessions, configure env.php and redis.conf for separate instances, and use monitoring to catch it early when Redis sizing hits its limits.
