vapor-chamber — Lightweight command bus for Vue Vapor
Architecture: CORE (zero dependencies, framework-agnostic): command-bus — dispatch, register, plugins, hooks, wildcard, request/respond testing — createTestBus, snapshot, time-travel
OPTIONAL (tree-shaken when unused): plugins — logger, validator, history, debounce, throttle, authGuard, optimistic plugins-io — retry, persist, sync chamber — Vue composables: useCommand, useCommandBus, useCommandGroup, … chamber-vapor — Vue 3.6+ Vapor-specific API (requires Vue 3.6) http — postCommand, createHttpClient, CSRF token reading transports — createHttpBridge, createWsBridge, createSseBridge form — createFormBus, reactive form state schema — LLM tool-use layer, synthesize, toTools devtools — @vue/devtools-api integration (requires @vue/devtools-api) transitions — hook → bus dispatch bridge ssr — SSR dehydrate/rehydrate plugin directives — v-command Vue directive (requires Vue) vite — HMR plugin (requires Vite, see 'vapor-chamber/vite') iife — UMD/IIFE bundle (see 'vapor-chamber/iife')
Sub-path exports that avoid pulling in optional code: 'vapor-chamber/transports' — HTTP + WS + SSE bridges 'vapor-chamber/transitions' — hook → bus dispatch 'vapor-chamber/ssr' — SSR dehydrate/rehydrate 'vapor-chamber/directives' — v-command directive 'vapor-chamber/vite' — Vite HMR plugin 'vapor-chamber/iife' — IIFE bundle (full) 'vapor-chamber/iife-core' — IIFE bundle (no Vapor custom-element, no Suspense paths) 'vapor-chamber/iife-elements' — IIFE bundle (core + Vapor custom-element)

Unseal a sealed bus. Dev/HMR only — if your production code never imports unsealBus, it gets tree-shaken out entirely, making seal() irreversible.
