microsoft-webui-handler

High-performance template renderer for the WebUI framework. Consumes the compiled binary protocol and produces HTML output at request time.

Overview

microsoft-webui-handler evaluates expressions, resolves state bindings, and renders full or partial HTML responses from pre-compiled WebUI protocol buffers — with no JavaScript runtime required.

Key Functions

`Protocol::render_partial`

Returns a complete client-navigation response with active-route projected state.

`Protocol::render_component_templates`

Returns compiled templates and CSS for specific components by tag name. Used for on-demand loading of components not in the route tree (dialogs, overlays). Supports inventory-based deduplication.

let result = protocol.render_component_templates(
    &["settings-dialog", "notification-panel"],
    &inventory_hex,
);
// Returns: { templates: [...], templateStyles: [...], inventory: "..." }

Available via all bindings: Rust (Protocol::render_component_templates), Node/WASM/npm (Protocol.renderComponentTemplates), and FFI (webui_protocol_render_component_templates).
