GPU
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The GPU interface of the WebGPU API is the starting point for using WebGPU. It can be used to return a GPUAdapter from which you can request devices, configure features and limits, and more.
The GPU object for the current context is accessed via the Navigator.gpu or WorkerNavigator.gpu properties.
Instance properties
wgslLanguageFeaturesRead only-
A
WGSLLanguageFeaturesobject that reports the WGSL language extensions supported by the WebGPU implementation.
Instance methods
requestAdapter()-
Returns a
Promisethat fulfills with aGPUAdapterobject instance. From this you can request aGPUDevice, which is the primary interface for using WebGPU functionality. getPreferredCanvasFormat()-
Returns the optimal canvas texture format for displaying 8-bit depth, standard dynamic range content on the current system.
Examples
Requesting an adapter and a device
async function init() {
if (!navigator.gpu) {
throw Error("WebGPU not supported.");
}
const adapter = await navigator.gpu.requestAdapter();
if (!adapter) {
throw Error("Couldn't request WebGPU adapter.");
}
const device = await adapter.requestDevice();
// ...
}
Configuring a GPUCanvasContext with the optimal texture format
const canvas = document.querySelector("#gpuCanvas");
const context = canvas.getContext("webgpu");
context.configure({
device,
format: navigator.gpu.getPreferredCanvasFormat(),
alphaMode: "premultiplied",
});
