Readme

@openelement/core

Advanced openElement runtime kernel.

Most users should start from @openelement/app, @openelement/element, or @openelement/ui. @openelement/core owns low-level primitives used by those products:

JSX and VNode runtime primitives.
DSD rendering through renderDsd() and renderDsdStream().
Static props, event hydration, island metadata, and SSR context helpers.
Unified errors, signal-like utilities, and DOM rendering helpers.
StyleSheet (SSR-safe CSSStyleSheet abstraction).

The OpenElement base class is now authored from @openelement/element.

This package does not contain Vite, CLI, or build orchestration logic.

Hydration Subpaths

@openelement/core/hydrate is a low-level building-block subpath for DSD marker, event, binding, and HydrationScope hydration. It is not a complete standalone third-party framework hydration runtime. Use:

@openelement/app for routes, pages, islands, and SPA bootstrap.
@openelement/element for Basic Element component authoring.
@openelement/core/static for SSR/DSD rendering without DOM hydration.
@openelement/core/hydrate for DSD marker/event/binding hydration helpers.
@openelement/core/csr for full client-side DOM rendering primitives.

The active contract is documented in docs/current/HYDRATION_CONTRACT.md.

Install

npm install @openelement/core

Low-Level Component Authoring

For component authoring with OpenElement, ErrorBoundary, prop system, and defineElement helper, use @openelement/element:

npm install @openelement/element
