plugin-storage Storage Plugin

What's a storage plugin?

Verdaccio by default uses a file system storage plugin local-storage. The default storage can be easily replaced, either using a community plugin or creating one by your own.

API

Storage plugins are composed of two objects, the IPluginStorage<T> and the IPackageStorage.

  • The IPluginStorage object handle the local database for private packages.
interface IPluginStorage<T> extends IPlugin<T>, ITokenActions {
  logger: Logger;
  config: T & Config;
  add(name: string, callback: Callback): void;
  remove(name: string, callback: Callback): void;
  get(callback: Callback): void;
  getSecret(): Promise<string>;
  setSecret(secret: string): Promise<any>;
  getPackageStorage(packageInfo: string): IPackageStorage;
  search(
    onPackage: onSearchPackage,
    onEnd: onEndSearchPackage,
    validateName: onValidatePackage
  ): void;
}
  • The IPackageStorage is an object that is created by each request that handles the I/O actions for the metadata and tarballs.
interface IPackageStorage {
  logger: Logger;
  writeTarball(pkgName: string): IUploadTarball;
  readTarball(pkgName: string): IReadTarball;
  readPackage(fileName: string, callback: ReadPackageCallback): void;
  createPackage(pkgName: string, value: Package, cb: CallbackAction): void;
  deletePackage(fileName: string, callback: CallbackAction): void;
  removePackage(callback: CallbackAction): void;
  updatePackage(
    pkgFileName: string,
    updateHandler: StorageUpdateCallback,
    onWrite: StorageWriteCallback,
    transformPackage: PackageTransformer,
    onEnd: CallbackAction
  ): void;
  savePackage(fileName: string, json: Package, callback: CallbackAction): void;
}

I'm all done. Running npm install for you to install the required dependencies. If this fails, try running the command yourself.
