## What's an Storage Plugin? {#whats-an-storage-plugin}
Verdaccio by default uses a file system storage plugin [local-storage](https://github.com/verdaccio/verdaccio/tree/master/packages/plugins/local-storage). The default storage can be easily replaced, either using a community plugin or creating one by your own.
### API {#api}
Storage plugins are composed of two objects, the `IPluginStorage<T>` and the `IPackageStorage`.
* The `IPluginStorage` object handle the local database for private packages.
```typescript
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.
```typescript
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;
}
```
