Amazon Chime SDK adds Data Messages for Real-time Signaling

Starting today, application developers building on the Amazon Chime SDK for JavaScript can use data messages to send signals between clients connected to an Amazon Chime SDK meeting. Messages can be any small data payload in any format that a developer wants to transmit in real-time between meeting attendees. Developers can use data messages to indicate changes to meeting state, power custom-built collaborative features such as emoji reactions or shared whiteboards, or for other purposes appropriate to their application.

The latest version of the Amazon Chime SDK for JavaScript (available on npm) includes new interfaces to broadcast and receive data messages of up to 2 KB. Messages are not stored persistently, but can be buffered and replayed for up to five minutes to “catch up” clients that are just joining the meeting.

The Amazon Chime SDK is a set of real-time communications components that developers can use to quickly add audio calling, video calling, and screen sharing capabilities to their own web or mobile applications. Developers can leverage the same communication infrastructure and services that power Amazon Chime, an online meetings service from AWS, and deliver engaging experiences in their applications.
