NodeFS File Storage Driver for Tachyon Drive and Tachyon Drive Crypto processor

Initialize simple JSON file storage driver

const driver = new FileStorageDriver(
  "FileStorageDriver",
  "./store.json",
  bufferSerializer,
);

Initialize crypt processor with JSON file storage driver

const processor = new CryptoBufferProcessor(Buffer.from("some-secret-key"));
const driver = new FileStorageDriver(
  {
    name: "FileStorageDriver",
    fileName: "./store.json.aes",
    logger: console,
  },
  bufferSerializer,
  processor,
);

Example usage of local notification file updates when running multiple process on same host

const fileUpdateNotify = new FileUpdateNotify("./store.notify");
const driver = new SomeDriver(
  { name: "SomeDriverWithoutUpdateNotification" },
  bufferSerializer,
  fileUpdateNotify,
);

//  includes common strToBufferSerializer
const jsonSerialization: IPersistSerializer<Data, string> = {
  deserialize: (buffer: string) => JSON.parse(buffer.toString()),
  serialize: (data: Data) => JSON.stringify(data),
  validator: (data: Data) => dataSchema.safeParse(data).success,
};

const bufferSerializer: IPersistSerializer<Data, Buffer> = nextSerializer<
  Data,
  string,
  Buffer
>(jsonSerialization, strToBufferSerializer);
