Creating a WebSocket Server
Let’s learn how to develop a WebSocket server with Go.
We'll cover the following
The WebSocket protocol
The WebSocket protocol is a computer communications protocol that provides full-duplex (transmission of data in two directions simultaneously) communication channels over a single TCP connection. The WebSocket protocol is defined in RFC 6455 and uses ws://
and wss://
instead of http://
and https://
, respectively. Therefore, the client should begin a WebSocket connection by using a URL that starts with ws://
.
In this lesson, we are going to develop a small yet fully functional WebSocket server using the gorilla/websocket
module. The server implements the Echo service, which means that it automatically returns its input to the client.
