Google has launched a Realtime API for Google Drive, enabling developers to create apps that can tap into Drive's real-time editing capabilities.
The API provides developers with collaborative versions of data objects such as maps, lists, strings, and JSON values, which are automatically synchronized, and all modifications to them are stored. Developers can create apps that read from and write to these objects like any local object.
If the basic set of objects isn't enough, developers can also create custom objects and references, which includes trees and arbitrary graph structures.
Companies such as Neutron Drive, draw.io and Gantter are already using the new API, according to Google. Other interested developers can check out the Google Drive Realtime API technical documentation here.
