The getConfiguration() method of the
{{domxref("GPUCanvasContext")}} interface returns the current configuration set for the context.
getConfiguration()
None.
An object containing the configuration options set on the context (i.e., via the {{domxref("GPUCanvasContext.configure()")}} method), or null if no configuration is set (either no configuration was previously set, or a configuration was set and then {{domxref("GPUCanvasContext.unconfigure()")}} was called on the context).
const canvas = document.querySelector("canvas");
const context = canvas.getContext("webgpu");
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();
context.configure({
device,
format: navigator.gpu.getPreferredCanvasFormat(),
alphaMode: "premultiplied",

console.log(context.getConfiguration());
/* Logs something like:
