The label property of the GPUShaderModule interface provides 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.createShaderModule() call, or you can get and set it directly on the GPUShaderModule object.

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

Setting and getting a label via GPUShaderModule.label:

// ...

const shaderModule = device.createShaderModule({
  code: shaders,
});

shaderModule.label = "myshader";

console.log(shaderModule.label); // "myshader"

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

// ...

const shaderModule = device.createShaderModule({
  code: shaders,
  label: "myshader",
});

console.log(shaderModule.label); // "myshader"
