Example file upload handler

const handleFileUpload = async (
  _path: string,
  hash: string,
  prevHash?: string,
) => {
  console.log(
    `Uploading file ${_path} with hash ${hash} and previous hash ${prevHash}`,
  );

  return _path;
};

Example bun file hasher

const computeFileHash = async (_path: string) => {
  const comfyuiPath = values.comfyui_path;
  if (!comfyuiPath) {
    return;
  }

  const f = file(path.join(comfyuiPath, _path));
  const exist = await f.exists();
  if (exist) {
    const a = await f.arrayBuffer();
    const hasher = new Bun.CryptoHasher("sha256");
    hasher.update(a);
    const hash = hasher.digest("base64");

    return hash;
  }
};
