This summary explores how to broadcast a video chat live to many viewers online using the Vonage Video API (formerly TokBox OpenTok) and Node.js. The tutorial covers setting up a server-side code using Glitch, client-side code in vanilla JavaScript, and implementing the startBroadcast() and stopBroadcast() methods for broadcasting with the Vonage Video API. It also includes creating a shareable HLS link to stream the video chat to a player that supports the format. Additionally, it provides a basic implementation of copy to clipboard functionality. The tutorial concludes by providing the final code on Glitch and GitHub, as well as resources for further learning and support.
