Node.js adapter for @nmmty/lazycanvas, powered by @napi-rs/canvas — a fast, dependency-free Skia binding with prebuilt binaries for Linux, macOS and Windows.

Installation

npm install @nmmty/lazycanvas @nmmty/adapter-node

Requires Node.js 18 or newer. @napi-rs/canvas is installed automatically.

Usage

import { NodeCanvasAdapter } from "@nmmty/adapter-node";
import { MorphLayer, Scene } from "@nmmty/lazycanvas";

const scene = new Scene(400, 200, { adapter: new NodeCanvasAdapter() });
scene.load(new MorphLayer({ color: "#22c55e", size: { width: 400, height: 200 } }));

await new Exporter(scene).export("png", { name: "out", saveAsFile: true });
