GPU Detection API

Utilities for checking WebGPU availability.

isWebGPUAvailable

Async boolean indicating if WebGPU is supported.

const isWebGPUAvailable: Promise<boolean>;

Example

import { isWebGPUAvailable } from 'webgpu-fft';

if (await isWebGPUAvailable) {
  console.log('WebGPU is available!');
}

hasWebGPUSupport()

Synchronous check for basic WebGPU API availability.

function hasWebGPUSupport(): boolean;

This checks if navigator.gpu exists but does not verify that a GPU adapter is available.

Example

import { hasWebGPUSupport } from 'webgpu-fft';

if (!hasWebGPUSupport()) {
  console.log('WebGPU API not available in this browser.');
}

Recommendation

Always use isWebGPUAvailable for the most accurate check:

import { createFFTEngine, isWebGPUAvailable } from 'webgpu-fft';

if (await isWebGPUAvailable) {
  const engine = await createFFTEngine();
  // Use GPU engine
} else {
  // Fall back to cpuFFT
}
