worker-factory/src/helpers/is-supporting-transferables.ts

A little factory function to create a JSON-RPC based Web Worker implementation.

// Bug #1: Safari does currently not support to use transferables.

export const isSupportingTransferables = () =>
    new Promise<boolean>((resolve) => {
        const arrayBuffer = new ArrayBuffer(0);
        const { port1, port2 } = new MessageChannel();

        port1.onmessage = ({ data }) => resolve(data !== null);
        port2.postMessage(arrayBuffer, [arrayBuffer]);
    });
