Building accessible interfaces does not require expensive extra tooling. Chrome and Firefox already ship with an Accessibility panel, a computed name inspector and color vision deficiency simulation, everything needed to check roles, names and contrast right in the browser. This article shows how to use these built in tools effectively and where the Lighthouse Accessibility Audit reaches its limits.

The Expo Modules API replaces hand-written React Native bridging with a declarative Swift and Kotlin DSL for building custom native modules without manual bridging boilerplate. This article covers the architecture, a full hands-on example, and the limits of testing inside Expo Go.

Classic RAG retrieves documents once and answers the question with the context it found. Agentic RAG goes a step further: Claude itself decides whether a first retrieval pass is enough, whether a follow-up query with refined search terms is needed, or whether multiple distinct knowledge sources must be combined. This article shows how to build such pipelines with clean tool definitions, where their limits lie, and how to debug multi-step chains when something goes wrong.

Anyone still writing manual $request->query->get() and json_decode($request->getContent()) in Symfony controllers is giving up type safety and validation for nothing. MapQueryString and MapRequestPayload have mapped query parameters and request bodies directly into typed DTOs since Symfony 6.3, automatically deserialized, validated, and ready to use.

Long lists that load more content on scroll are one of the most common UI requirements, but naive implementations regularly fail on duplicates, memory usage and inconsistent scroll position. TanStack Query's infinite query solves these problems with a clear page structure, cursor based navigation, and combines with virtualization to render even tens of thousands of items smoothly.

A manually maintained @theme block spirals out of control once the same color values are also needed for native apps, Figma, or a second frontend. A theme generator reads a single JSON token file as the single source of truth and automatically produces the Tailwind CSS v4 @theme block from it, consistent across every platform.

A green end to end test does not prove that every consumer of a Symfony API keeps working once a response field changes. Contract testing makes every consumer's expectations explicit and checks them automatically against the real provider, long before a breaking change causes damage in production.

Shipping several brands from a single Hyva codebase sounds simple as long as it is only a different logo. Once color palettes, font sizes, and entire spacing systems need to vary per brand, the choice between CSS variables and separate Tailwind configs decides how maintainable the setup still is a year from now.

Vue Testing is effective when tests verify behavior from the user's perspective, not implementation details. Vitest as a blazing fast test runner and Vue Testing Library as a user oriented test framework are the combination that produces robust tests that survive refactoring.

A Docker image build that starts from zero on every push in GitHub Actions wastes minutes that can be almost entirely eliminated with the right cache strategy for docker/build-push-action, once you understand the differences between GitHub Actions cache, registry cache, and inline cache.
