sdx 1.0.0-alpha2

Highlights

• Twig integration: new {{ sdx('my_theme:hero', {title: 'Hello'}) }} Twig function for embedding SDX components in any Twig-based Drupal theme. No additional modules required.
• Framework-agnostic SSR: sdx_ssr no longer depends on sdx_react. Works with React, Vue, or Svelte, whichever framework plugin is active.
• SPA router: new sdx_router submodule with link interception, prefetch on hover, scoped partial page responses, form interception, and confirm form modals.
• Vue and Svelte base components: sdx_vue and sdx_svelte now ship full base component libraries (templates, usePage composable) matching sdx_react parity.
• Production-grade SSR server: clustered Node.js (1 worker per CPU), LRU cache with Drupal cache tag purging, circuit breaker, streaming, zero-downtime restart.

New submodules

• sdx_router: SPA navigation for SDX-powered themes. Link interception, prefetch, scoped partial responses, form interception, batch modal support, theme boundary detection.
• sdx_preflight: environment preflight checks and real-time module foundation.

sdx (core)

• Add sdx() Twig function via SdxTwigExtension for embedding components in Twig themes
• Add SdxAliasDiscovery service: @theme:{name}/, @module:{name}/, @sdx/* import aliases for Vite builds
• Add SdxEnvironmentChecker service for runtime checks
• Expand ComponentDiscoveryManager with cross-extension scanning (modules + themes)
• Expand ComponentPreRender with data resolver integration and framework-aware props storage
• Improve DataResolver: simplified API, removed deprecated data sources
• Improve ComponentScaffolder: streamlined generation
• Improve setup wizard with better framework and package manager detection
• Migrate all preprocess hooks from .module to PHP 8 attribute-based Hook class
• Remove dead code: SdxSystemCheck plugin system, annotation classes
• Fix DI violations throughout (no more static \Drupal:: calls)

sdx_ssr

• Remove hard dependency on sdx_react: SSR is now framework-agnostic
• Clustered Node.js server (1 worker per CPU, auto-restart, SIGHUP zero-downtime restart)
• LRU render cache with Drupal cache tag index for surgical invalidation
• SsrCacheTagInvalidator: entity saves trigger POST /cache/purge to Node.js
• Circuit breaker in PHP: 3 failures result in 30s cooldown via Drupal State API
• Full-page SSR via /render-page endpoint with streaming support
• /health endpoint with cache stats (size, hits, misses, hitRatio)
• Fix hardcoded react/vite node_modules path: now discovers active framework dynamically

sdx_router

• SPA link interception with X-SDX-Navigate header
• Prefetch on hover via NavigationStateManager
• Scoped partial responses (content/page/full): server declares scope
• Form interception with AJAX batch modal support
• Confirm form modal system for entity delete operations
• Theme boundary crossing detection with full reload fallback
• drupalSettings replacement on navigation

sdx_react

• usePage hook with scope-aware mergePageData() (content/page/full/DataProvider)
• SpaShell component with NavigationStateManager subscription
• HtmlFragment component: three rendering modes (ComponentNode[], token string, plain HTML)
• Full base component library: form-element, details, table, vertical-tabs, dropbutton, views-view, admin-page, block templates, and more
• Persistent layout support via _layout metadata

sdx_vue / sdx_svelte

• Full base component libraries matching sdx_react parity
• usePage composable (Vue) with scope-aware merging
• Template auto-discovery for templates/ directory convention
