WebSockets

What are WebSockets?

WebSocket protocol allows for simultaneous two-way communication between the client and the server. Applications such as chatting apps and multiplayer games that rely on real-time connection with the server use WebSockets for their communication.

GetX’s internal networking library, GetConnect, allows us to establish long-lived connections with the server over WebSockets. This lesson will teach us how to manage a socket connection with the server and listen to real-time updates.

Establishing connection

We manage a WebSocket connection in GetConnect using the GetSocket class. With GetSocket, we get the methods to establish a connection, close it, and listen to the messages that pass to and from the client and server. To establish a connection, we follow three simple steps:

1. Create an instance of GetConnect. We use it to create a socket connection.
