Capability

The native engine owns script, document state, layout, and paint together so high-frequency component work does not bounce through the managed UI thread.

How it composes

From intent
to working system.

Script

V8 executes trusted packaged JavaScript and TypeScript output in a dedicated isolate.

Platform

The bounded DOM, CSS, events, layout, Canvas, and SVG surface implements the supported profile.

Scene

Native layout and paint produce immutable updates instead of chatty object-level interop.

Validate

Curated WPT cases and product-scale fixtures measure declared compatibility.

Quick start

Adopt this
capability.

Start with the primary module, then add the related packages only when the application needs those layers. Replace VERSION with the current NuGet version.

git clone --recurse-submodules https://github.com/wieslawsoltes/WebScene.git
dotnet run --project samples/NativeRuntimeShowcase.Avalonia

const canvas = document.querySelector("canvas");
const context = canvas.getContext("2d");
context.fillStyle = "#8ea2ff";
context.fillRect(24, 24, 160, 80);
