Module Federation (Webpack 5) allows JavaScript modules to be loaded from a remote URL at runtime — meaning one WordPress plugin can expose a React component, utility library, or data store, and another plugin can consume it without bundling a copy. This solves the classic WordPress “multiple jQuery / multiple React” problem for plugin ecosystems…

MySQL’s optimiser hints (available since 5.7, extended in 8.0) let you override the query planner’s decisions without changing session variables or schema — they are embedded directly in the query with /*+ HINT */ syntax and affect only that specific statement. For WordPress performance work, hints are invaluable when the optimiser consistently makes a bad…

Native WooCommerce supports a single currency, but geo-pricing — showing prices in the visitor’s local currency based on their IP country — is a first-class requirement for international stores. Implementing multi-currency without a premium plugin requires: a currency detection layer, an exchange-rate source (cached API or manual table), price conversion filters, and cart/checkout currency locking…

Hardcoding API keys and database passwords in wp-config.php — even with restrictive file permissions — creates a single point of secret compromise: anyone with read access to the file system has all credentials. A secrets manager (HashiCorp Vault, Doppler, AWS Secrets Manager, or 1Password Secrets Automation) rotates, audits, and injects secrets at runtime, so your…

The CSS Typed Object Model API (element.attributeStyleMap and element.computedStyleMap()) exposes CSS values as typed JavaScript objects — CSSUnitValue, CSSColorValue, CSSTransformValue — instead of raw strings. This eliminates the string-parsing overhead in animation loops, provides unit-aware arithmetic (CSS.px(10).add(CSS.rem(2))), and integrates with the Worklet-based Houdini painting pipeline.

The Block Bindings API (stable in WordPress 6.5) lets you connect core block attributes — content on Paragraph, url/alt on Image, href/text on Button — directly to custom data sources registered in PHP, without writing a custom dynamic block. This is the FSE equivalent of ACF’s display functions: your data source provides the value, the…

WCAG 2.2 (published 2023) adds nine new success criteria to the existing 2.1 standard, with the most impactful changes for WordPress themes being: 2.4.11 Focus Appearance (focus indicators must be at least 2px thick with 3:1 contrast), 2.4.12 Focus Not Obscured (sticky headers must not completely cover focused elements), and 3.2.6 Consistent Help (help links…

Pest is a modern PHP testing framework built on top of PHPUnit that provides a more expressive, fluent API — expect($value)->toBe(42) — and reduces test boilerplate significantly. Pest’s higher-order tests, built-in parallel test execution, and architectural testing rules (arch()) make it a compelling alternative to raw PHPUnit for WordPress plugin test suites.

The WordPress REST API returns full post objects by default — including 40+ fields, embedded author objects, and taxonomy arrays — even when the client only needs the title and permalink. The _fields parameter enables sparse fieldsets to reduce payload size by 80–90%, and combining sparse fieldsets with HTTP caching headers and a Redis-backed response…
