Vonage Client SDK for JavaScript

The Client SDK is intended to provide a ready solution for developers to build Programmable Conversation applications across multiple Channels including: Messages, Voice, SIP, websockets, and App.

The following media types are supported:

• Push Notifications – Keep users aware of important alerts by sending notifications to their device.

• Text and Image Support – Users can quickly send and receive texts and images from your application.
