The GPUDevice interface of the WebGPU API represents a logical GPU device. This is the main interface through which the majority of WebGPU functionality is accessed.

A GPUDevice object is requested using the GPUAdapter.requestDevice() method.

Inherits properties from its parent, EventTarget.

features Experimental Read only

A GPUSupportedFeatures object that describes additional functionality supported by the device.

label Experimental

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

limits Experimental Read only

A GPUSupportedLimits object that describes the limits supported by the device.

lost Experimental Read only

Contains a Promise that remains pending throughout the device's lifetime and resolves with a GPUDeviceLostInfo object when the device is lost.

queue Experimental Read only

Returns the primary GPUQueue for the device.

Inherits methods from its parent, EventTarget.

createBindGroup() Experimental

Creates a GPUBindGroup based on a GPUBindGroupLayout that defines a set of resources to be bound together in a group and how those resources are used in shader stages.

createBindGroupLayout() Experimental

Creates a GPUBindGroupLayout that 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.

createBuffer() Experimental

Creates a GPUBuffer in which to store raw data to use in GPU operations.

createCommandEncoder() Experimental

Creates a GPUCommandEncoder, which is used to encode commands to be issued to the GPU.

createComputePipeline() Experimental

Creates a GPUComputePipeline that can control the compute shader stage and be used in a GPUComputePassEncoder.

createComputePipelineAsync() Experimental

Returns a Promise that fulfills with a GPUComputePipeline, which can control the compute shader stage and be used in a GPUComputePassEncoder, once the pipeline can be used without any stalling.

createPipelineLayout() Experimental

Creates a GPUPipelineLayout that defines the GPUBindGroupLayouts used by a pipeline. GPUBindGroups used with the pipeline during command encoding must have compatible GPUBindGroupLayouts.

createQuerySet() Experimental

Creates a GPUQuerySet that can be used to record the results of queries on passes, such as occlusion or timestamp queries.

createRenderBundleEncoder() Experimental

Creates a GPURenderBundleEncoder that can be used to pre-record bundles of commands. These can be reused in GPURenderPassEncoders via the executeBundles() method, as many times as required.

createRenderPipeline() Experimental

Creates a GPURenderPipeline that can control the vertex and fragment shader stages and be used in a GPURenderPassEncoder or GPURenderBundleEncoder.

createRenderPipelineAsync() Experimental

Returns a Promise that fulfills with a GPURenderPipeline, which can control the vertex and fragment shader stages and be used in a GPURenderPassEncoder or GPURenderBundleEncoder, once the pipeline can be used without any stalling.

createSampler() Experimental

Creates a GPUSampler, which controls how shaders transform and filter texture resource data.

createShaderModule() Experimental

Creates a GPUShaderModule from a string of WGSL source code.

createTexture() Experimental

Creates a GPUTexture in which to store texture data to use in GPU rendering operations.

destroy() Experimental

Destroys the device, preventing further operations on it.

importExternalTexture() Experimental

Takes an HTMLVideoElement as an input and returns a GPUExternalTexture wrapper object containing a snapshot of the video that can be used in GPU rendering operations.

popErrorScope() Experimental

Pops an existing GPU error scope from the error scope stack and returns a Promise that resolves to an object (GPUInternalError, GPUOutOfMemoryError, or GPUValidationError) describing the first error captured in the scope, or null if no error occurred.

pushErrorScope() Experimental

Pushes a new GPU error scope onto the device's error scope stack, allowing you to capture errors of a particular type.

uncapturederror Experimental

Fired when an error is thrown that has not been observed by a GPU error scope, to provide a way to report unexpected errors. Known error cases should be handled using pushErrorScope() and popErrorScope().

async function init() {
  if (!navigator.gpu) {
    throw Error("WebGPU not supported.");
  }

  const adapter = await navigator.gpu.requestAdapter();
  if (!adapter) {
    throw Error("Couldn't request WebGPU adapter.");
  }

  const device = await adapter.requestDevice();

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

  //...
}
