The **pasteboard** module provides the pasteboard management client and pasteboard server. The pasteboard management client manages pasteboard APIs. Specifically, it provides pasteboard APIs in JavaScript for applications, creates pasteboard data on the application framework side, and requests the pasteboard SA to create, delete, query, convert text, and configure pasteboards. The pasteboard server manages pasteboard events as well as the pasteboard SA lifecycle, providing support for the copy and paste functions of the system.
The **pasteboard** module provides the copy and paste support for the system pasteboard. You can use the APIs of this module to operate pasteboard content of the plain text, HTML, URI, Want, pixel map, and other types.
