The label property of the {{domxref("GPUBuffer")}} interface provides a label that can be used to identify the object, for example in {{domxref("GPUError")}} messages or console warnings.

This can be set by providing a label property in the descriptor object passed into the originating {{domxref("GPUDevice.createBuffer()")}} call, or you can get and set it directly on the GPUBuffer object.

Value

A string. If this has not been previously set as described above, it will be an empty string.

Examples

Setting and getting a label via GPUBuffer.label:

js
const output = device.createBuffer({
  size: BUFFER_SIZE,
  usage: GPUBufferUsage.STORAGE | GPUBufferUsage.COPY_SRC,
});

output.label = "my_buffer";

console.log(output.label); // "my_buffer"

Setting a label via the originating {{domxref("GPUDevice.createBuffer()")}} call, and then getting it via GPUBuffer.label:

js
const output = device.createBuffer({
  size: BUFFER_SIZE,
  usage: GPUBufferUsage.STORAGE | GPUBufferUsage.COPY_SRC,
  label: "my_buffer",
});

console.log(output.label); // "my_buffer"
