GPUCompilationMessage: length property

{{APIRef("WebGPU API")}}{{SecureContext_Header}}{{AvailableInWorkers}}

The length read-only property of the {{domxref("GPUCompilationMessage")}} interface is a number representing the length of the substring that the message corresponds to.

Value

A number.

To be precise, length is the number of {{glossary("UTF-16", "UTF-16 code units")}} in the shader code substring that the message corresponds to. If the message corresponds to a single point rather than a substring, length will be 0.

Examples

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

const shaderInfo = await shaderModule.getCompilationInfo();
const firstMessage = shaderInfo.messages[0];
console.log(firstMessage.length);

See the main GPUCompilationInfo page for a more detailed example.
