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 label read-only property of the GPUCommandEncoder 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 GPUDevice.createCommandEncoder() call, or you can get and set it directly on the GPUCommandEncoder 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 GPUCommandEncoder.label:

js
const commandEncoder = device.createCommandEncoder();
commandEncoder.label = "my_command_encoder";
console.log(commandEncoder.label); // "my_command_encoder"

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

js
const commandEncoder = device.createCommandEncoder({
  label: "my_command_encoder",
});

console.log(commandEncoder.label); // "my_command_encoder"
