3.0.0 — 2026-03-18

Complete rewrite as a monorepo with 17 packages. Breaking changes from v2.x.

New packages

  • @alt-javascript/common — shared kernel (global ref, environment detection)
  • @alt-javascript/jsdbc-template — JsdbcTemplate, NamedParameterJsdbcTemplate, auto-configuration
  • @alt-javascript/boot-express — Express adapter with ControllerRegistrar
  • @alt-javascript/boot-fastify — Fastify adapter
  • @alt-javascript/boot-koa — Koa adapter
  • @alt-javascript/boot-hono — Hono adapter (Web Standards API)
  • @alt-javascript/boot-lambda — AWS Lambda adapter (API Gateway HTTP API v2)
  • @alt-javascript/boot-cloudflare-worker — Cloudflare Workers adapter
  • @alt-javascript/boot-azure-function — Azure Functions adapter
  • @alt-javascript/boot-vue — Vue 3 CDI integration
  • @alt-javascript/boot-alpine — Alpine.js CDI integration
  • @alt-javascript/boot-react — React CDI integration (Context/hooks)
  • @alt-javascript/boot-angular — Angular CDI integration (providers)

Core enhancements

  • Auto-discovery: static __component class property for self-registering components
  • AOP: before/after/around/afterReturning/afterThrowing advice via JS Proxy
  • Application events: typed event bus with ContextRefreshedEvent, ContextClosedEvent
  • BeanPostProcessor: intercept bean creation for cross-cutting concerns
  • Conditional registration: conditionalOnProperty, conditionalOnClass, conditionalOnMissingBean, conditionalOnProfile
  • Constructor injection: __inject static property specifies constructor dependencies
  • Circular dependency detection: fails fast with clear error message and dependency chain
  • dependsOn: explicit ordering of bean initialization
  • Primary beans: primary: true resolves ambiguous autowiring
  • Profile-aware config: Spring Boot-aligned file loading with NODE_ACTIVE_PROFILES
  • Property source chain: layered precedence (overrides → env → profile files → defaults → fallback)
  • YAML and .properties support: application.yaml, application.properties alongside JSON
  • Startup banner: configurable banner printed during ApplicationContext startup
  • Browser profiles: BrowserProfileResolver — declarative URL-to-profile mapping for browser apps
  • ProfileAwareConfig: profile-specific config overlays for browser environments

Breaking changes

  • Monorepo structure — install individual @alt-javascript/* packages
  • @alt-javascript/common extracts shared utilities previously duplicated across packages
  • Boot.boot() global context shape updated
  • Config WindowLocationSelectiveConfig replaced by BrowserProfileResolver + ProfileAwareConfig
