params

• canUseFileStorage?: boolean

Returns

The WebStorageModule class returns an object with the following properties:

class WebStorageModule implements IModule {
  moduleName: string;
  tbSDK: ITKeyApi;
  canUseFileStorage: boolean;
  constructor(canUseFileStorage?: boolean);
  setFileStorageAccess(): Promise<void>;
  setModuleReferences(tbSDK: ITKeyApi): void;
  initialize(): Promise<void>;
  storeDeviceShare(deviceShareStore: ShareStore, customDeviceInfo?: StringifiedType): Promise<void>;
  storeDeviceShareOnFileStorage(shareIndex: BNString): Promise<void>;
  getDeviceShare(): Promise<ShareStore>;
  inputShareFromWebStorage(): Promise<void>;
}

Usage

With the WebStorageModule, you've access to the following functions:

Store Device Share

storeDeviceShare(deviceShareStore: ShareStore, customDeviceInfo?: StringifiedType)

• deviceShareStore: The ShareStore object to store.
• customDeviceInfo?: Information about the device to store.

ShareStore

class ShareStore implements ISerializable {
  share: Share;
  polynomialID: PolynomialID;
  constructor(share: Share, polynomialID: PolynomialID);
  static fromJSON(value: StringifiedType): ShareStore;
  toJSON(): StringifiedType;
}
interface ISerializable {
  toJSON(): StringifiedType;
}

Storing a Share on File Storage

storeDeviceShareOnFileStorage(shareIndex)

• shareIndex: The index of the share to store.

Get a ShareStore from Storage

getDeviceShare()

Return
