The GPUBindGroupLayout interface of the WebGPU API defines the structure and purpose of related GPU resources such as buffers that will be used in a pipeline, and is used as a template when creating GPUBindGroups.

A GPUBindGroupLayout object instance is created using the GPUDevice.createBindGroupLayout() method.

label Experimental

A string providing a label that can be used to identify the object, for example in GPUError messages or console warnings.

Our basic compute demo shows an example of creating a bind group layout and then using that as a template when creating a bind group.

// ...

const bindGroupLayout = device.createBindGroupLayout({
  entries: [
    {
      binding: 0,
      visibility: GPUShaderStage.COMPUTE,
      buffer: {
        type: "storage",
      },
    },
  ],
});

const bindGroup = device.createBindGroup({
  layout: bindGroupLayout,
  entries: [
    {
      binding: 0,
      resource: {
        buffer: output,
      },
    },
  ],
});
