Claude comes in three capability tiers: Opus for deep reasoning and architectural decisions, Sonnet as a balanced all rounder for everyday development work, and Haiku for fast, cheap routine tasks. Picking the right tier often cuts production API cost more than prompt tuning ever does, while still delivering the quality each task actually needs.

A search feature that returns products, categories, and pages in one list outgrows any single object type. Union types and interfaces give GraphQL the tools to model such heterogeneous results without compromising type safety or introspection, with clear rules for which tool fits when.

Using fetch() directly gives TypeScript no guarantee about the shape of the response: response.json() returns any, and a plain generic parameter validates nothing at runtime. This article shows how a generic fetch wrapper with typed error results, timeout handling, and a practical API client brings real type safety to Magento and headless projects.

Anyone building custom frontend blocks in a Hyvä theme, product recommendations, bespoke widgets or filter logic, will eventually need custom Hyvä GraphQL queries. Structured correctly, preloaded server-side and cached on multiple layers, they deliver fresh data quickly without putting the Full Page Cache or page speed at risk.

With scalars the difference between == and === is already tricky enough, but with objects an entirely separate dimension appears that many developers underestimate. == compares class and every property recursively for objects, while === checks only whether both operands refer to the exact same instance in memory. PHP offers no magic method like __equals to customize this behavior. This article explains both operators precisely and shows how to build predictable, custom comparison logic for value objects.

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.

An exact count of unique values across billions of documents would be nearly impossible to justify in terms of memory. The cardinality aggregation solves this problem with the HyperLogLog++ algorithm, which approximates the number of unique values with constant, very small memory usage instead of remembering every value individually. The precision_threshold parameter decides how tightly accuracy and memory usage are coupled, and this article shows when the resulting error rate is completely unproblematic from a business perspective.

Tuning Elasticsearch and OpenSearch
Synonyms, Boosters, Filters

A good search experience in Magento 2 doesn't come from a running search server alone. Only when synonyms, relevance, filter logic, and catalog data work together with real domain knowledge does search deliver results that users actually find helpful.

1. What good search tuning in Magento 2 actually means

Running Elasticsearch Magento 2 or OpenSearch Magento 2 is not enough on its own to get good product search. A search server can respond fast and correctly and still prioritize

Once a REST API has to go through its first breaking change, the question of versioning strategy becomes unavoidable, and the three common approaches, URL path versioning, content negotiation via the Accept header, and a dedicated custom header, have fundamentally different effects on caching, client implementation, documentation, and actual usability for external integrators. Making the decision early and deliberately saves a painful, usually incomplete migration years later, once thousands of clients already depend on the originally, carelessly chosen structure.

For phrases like '3 days ago' or 'in 2 hours' you no longer need an external library: Intl.RelativeTimeFormat handles localized relative time natively in the browser, including rounding logic for all common time units.
