Installation

Install the package from the public package root:

npm i @synthesisengineering/prism

Use the package root for app code:

import { CanvasRuntime } from "@synthesisengineering/prism";

Subpath imports are not supported public API.

Enable native rendering

Native mode currently requires the browser's Canvas Draw Element flag.

Chrome:

1. Open chrome://flags/#canvas-draw-element.
2. Set Canvas Draw Element to Enabled.
3. Relaunch Chrome.

Brave:

1. Open brave://flags/#canvas-draw-element.
2. Set Canvas Draw Element to Enabled.
3. Relaunch Brave.

The flag is browser-local. Enabling it in Chrome does not enable it in Brave.

Fallback

Prism can run in fallback mode for compatibility, but fallback is lower fidelity than native HTML-in-Canvas. Treat it as a compatibility path, not the definition of Prism's rendering behavior.
