Gift cards in Magento 2 are more than a simple voucher field: a clean data model in the giftcardaccount, secure code generation, correct checkout total integration, multiple redemption per cart, a resilient admin workflow for batch campaigns, and hardened API protection for headless and GraphQL checkouts decide whether gift cards work reliably and securely in production.

Legacy code is code without tests, and it cannot be changed safely without tests. The way out of this dilemma begins with characterization tests: tests that document the actual behavior, not the desired one. Introduce seams, break static dependencies and extract classes step by step, without changing a single line of production logic before the first test is green.

Anyone building headless checkouts, POS integrations or marketplace sync for Magento 2 cannot avoid the Quote Management API. CartRepositoryInterface, CartManagementInterface and custom totals collectors replace fragile direct model access with stable, versioned service contracts that stay reliable even under heavy cart load.

On catalogs with several hundred thousand SKUs, the catalogsearch_fulltext indexer quickly becomes an operational bottleneck: full reindex runs take hours, the cron job blocks other jobs, and PHP workers hit their memory limits. This article shows how batch size, partial reindex strategies and the Elasticsearch Bulk API work together to noticeably improve indexer performance on large catalogs.

Anyone who needs their own data to be searchable or aggregated at speed cannot avoid building a custom indexer. Instead of running expensive calculations on every frontend request, a custom indexer moves the work into a controlled, repeatable process that runs exactly when the underlying data changes.

A React storefront built on Magento's GraphQL API fully decouples frontend and backend, making the shop faster, more flexible and easier to maintain. Teams that understand the schema, pick the right client and plan caching and error handling from day one save months of later rework.

How does Magento 2 process every HTTP request? Bootstrap, FrontController, router chain, URL rewriting and action classes, the complete path fully explained.

Anyone who only ever runs tests and CLI commands in the terminal loses valuable seconds on every cycle. Run configurations in PhpStorm turn the green play button into a real tool, with a Docker interpreter, Xdebug integration and compound runs for complex workflows.

Multilingual Magento stores rarely fail because of the translation itself, they fail because of the technical architecture behind it. Setting up store views, URL structure, hreflang linking, and language switchers cleanly avoids duplicate content, prevents lost ranking signals, and makes every language version independently visible in its own Google search, without forcing users into redirects they never asked for.

A red-outlined input field is useless to screen reader users if the error is not programmatically linked to the field. This article shows how aria-invalid, aria-describedby, and live regions reliably announce validation errors, including a complete accessible checkout example for Magento and Hyvä.
