GPURenderPassEncoder: label property

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 GPURenderPassEncoder 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.beginRenderPass() call, or you can get and set it directly on the GPURenderPassEncoder 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 GPURenderPassEncoder.label:

const commandEncoder = device.createCommandEncoder();

const renderPassDescriptor = {
  colorAttachments: [
    {
      clearValue: clearColor,
      loadOp: "clear",
      storeOp: "store",
      view: context.getCurrentTexture().createView(),
    },
  ],
};

const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);
passEncoder.label = "my_render_pass_encoder";

console.log(passEncoder.label); // "my_render_pass_encoder"

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

const commandEncoder = device.createCommandEncoder();

const renderPassDescriptor = {
  colorAttachments: [
    {
      clearValue: clearColor,
      loadOp: "clear",
      storeOp: "store",
      view: context.getCurrentTexture().createView(),
    },
  ],
  label: "my_render_pass_encoder",
};

const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);

console.log(passEncoder.label); // "my_render_pass_encoder"
