# Apps **Kind**: module | **Library**: @interopio/desktop | **Access**: `io.apps` **Source**: https://docs.interop.io/desktop/reference/javascript/apps/index.html > Note that the Apps API is still an experimental feature. This means that it may have hidden issues and may be subject to changes in future releases. > > The Apps API is designed to replace the legacy App Management API accessible via the [`io.appManager`](../app%20management/index.html#API) object. > The legacy App Management API is still supported, but will be entirely removed in a future release. It's highly recommended to migrate to the new Apps API. The Apps API provides a modern, fully asynchronous way to manage io.Connect Desktop apps. It offers abstractions for: - App - a program as a logical entity, registered in io.Connect Desktop with some metadata (name, description, icon, etc.) and with all the configuration needed to spawn one or more instances of it. The Apps API provides facilities for retrieving app metadata and for detecting when an app is started. - Instance - a running copy of an app. The Apps API provides facilities for starting/stopping app instances and tracking app-related events. The Apps API is accessible via the [`io.apps`](https://docs.interop.io/desktop/reference/javascript/apps/api/index.md) object. Available since io.Connect Desktop 10.0 &@interopio/desktop 6.16.0. ## Interfaces - [API](https://docs.interop.io/desktop/reference/javascript/apps/api/index.md): Apps API. - [AppAddedEvent](https://docs.interop.io/desktop/reference/javascript/apps/appaddedevent/index.md): Describes the argument received by the callback function for handling the app added event. - [AppChangeSet](https://docs.interop.io/desktop/reference/javascript/apps/appchangeset/index.md): Object with key/value pairs describing the updated app properties and their new values. - [AppDataOptions](https://docs.interop.io/desktop/reference/javascript/apps/appdataoptions/index.md): Options for selecting or filtering apps. - [AppFilter](https://docs.interop.io/desktop/reference/javascript/apps/appfilter/index.md): Filter for retrieving apps. - [Application](https://docs.interop.io/desktop/reference/javascript/apps/application/index.md): Describes an app. - [ApplicationCore](https://docs.interop.io/desktop/reference/javascript/apps/applicationcore/index.md): Describes the basic properties of an app. - [ApplicationInstance](https://docs.interop.io/desktop/reference/javascript/apps/applicationinstance/index.md): Describes an app instance. - [AppRegistry](https://docs.interop.io/desktop/reference/javascript/apps/appregistry/index.md): Object that can be used for managing app definitions. - [AppRemovedEvent](https://docs.interop.io/desktop/reference/javascript/apps/appremovedevent/index.md): Describes the argument received by the callback function for handling the app removed event. - [AppSelect](https://docs.interop.io/desktop/reference/javascript/apps/appselect/index.md): Options for selecting apps. - [AppUpdatedEvent](https://docs.interop.io/desktop/reference/javascript/apps/appupdatedevent/index.md): Describes the argument received by the callback function for handling the app updated event. - [ClearAppsOptions](https://docs.interop.io/desktop/reference/javascript/apps/clearappsoptions/index.md): Options for clearing all app definitions from the in-memory store. - [Definition](https://docs.interop.io/desktop/reference/javascript/apps/definition/index.md): App definition object.
