GPUCommandBuffer: label property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The label read-only property of the GPUCommandBuffer interface is a string providing a label that can be used to identify the object, for example in GPUError messages or console warnings.

This can be set by providing a label property in the descriptor object passed into the originating GPUCommandEncoder.finish() call, or you can get and set it directly on the GPUCommandBuffer object.

Value

A string. If no label value has previously been set, getting the label returns an empty string.

Examples

Setting and getting a label via GPUCommandBuffer.label:

const commandBuffer = commandEncoder.finish();
commandBuffer.label = "mycommandbuffer";
console.log(commandBuffer.label); // "mycommandbuffer";

Setting a label via the originating GPUCommandEncoder.finish() call, and then getting it via GPUCommandBuffer.label:

const commandBuffer = commandEncoder.finish({
  label: "mycommandbuffer",
});

console.log(commandBuffer.label); // "mycommandbuffer";
