import { promisify } from 'util';

const pipeline = promisify(stream.pipeline);

(async () => {
    const digestStream = new DigestStream({
        digest: crypto.createHash('sha256'),
    });

    await pipeline([
        fs.createReadStream('./shakespeare.txt'),
        digestStream,
        // ...
