The source property of the {{domxref("VRLayerInit")}} interface (dictionary) defines the canvas whose contents will be presented by the {{domxref("VRDisplay")}}.
[!NOTE] This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
An {{domxref("HTMLCanvasElement")}} or {{domxref("OffscreenCanvas")}} object.
See VRLayerInit for example code.
This property was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers. Read Meta's Porting from WebVR to WebXR guide for more information.
