GPUCommandBuffer

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 GPUCommandBuffer interface of the WebGPU API represents a pre-recorded list of GPU commands that can be submitted to a GPUQueue for execution.

A GPUCommandBuffer is created via the GPUCommandEncoder.finish() method; the GPU commands recorded within are submitted for execution by passing the GPUCommandBuffer into the parameter of a GPUQueue.submit() call.

Note: Once a GPUCommandBuffer object has been submitted, it cannot be used again.

Instance properties

Examples

const commandBuffer = commandEncoder.finish();
