Websocket Client
In today’s interconnected world, the need for real-time updates is paramount for websites and IoT applications.
A way to deliver information instantly to your sites or applications is to use the Websocket protocol which provides a full-duplex communication channel between a server and a client. From 4D V20, you can create a websocket server with the 4D.WebSocketServer class. We continue in v20 R2 with the 4D.WebSocket class that allows you to create a websocket client to connect to any websocket servers.
New Built-in Websocket Server
