Nuwax OpenUI Runtime

@nuwax-ai/openui-runtime ships the frozen static OpenUI renderer bundle (dist/runtime.js + dist/runtime.css) used by the Nuwax host for sidecar and file-preview rendering.

It is intentionally separate from the MCP server package (@nuwax-ai/openui-mcp):

• The MCP server is the small, fast-starting stdio process agents spawn. It must stay lean, so it does not carry this multi-megabyte renderer bundle.
• This package holds the heavy bundle (React, react-dom, the OpenUI component library, charts, syntax highlighting) inlined into a single self-contained runtime.js. It is never imported as a module — the host copies the static files into public/static/openui-runtime/.

The bundle is fully self-contained: every dependency is a devDependency (build-time only). There are no runtime dependencies.

Build

pnpm install
pnpm --filter @nuwax-ai/openui-runtime build

Produces dist/runtime.js and dist/runtime.css. The runtime is intentionally pure: it speaks only standard window.parent.postMessage and carries no web-view JSSDK or bridge logic — all uni-app x / 小程序 bridging lives in the host entry index.html (see Consuming).

Consuming (Nuwax host)

Run the host's pnpm sync:openui-runtime, which resolves this package and copies dist/{runtime.js,runtime.css} into public/static/openui-runtime/.

The runtime emits OPENUI_* only via window.parent.postMessage. The host-maintained entry index.html adapts that to the environment: in real iframes (PC web / H5) the parent receives the postMessage directly; in a top-level webview (App / 小程序, window.parent === window) it loads the official /static/uni.webview.1.5.5.js (the single JSSDK copy, kept in the nuwax repo — not shipped by this package) and runs a small bootstrap relay that forwards those messages to <web-view> @message via uni.webView.postMessage. This package stays free of any uni-webview coupling. The compact theme is shared from @nuwax-ai/openui-mcp/compact-theme. Form default-value sync (@nuwax-ai/openui-mcp/form-field-sync) is applied in RuntimeApp before the mobile-aware library so RadioGroup / Slider required validation matches the UI selected state.
