NEO Ping with Golang. Although many core libraries of NEO are written in C# or Python, for this tutorial we will us Golang. The communication basics are the same for all languages. The NEO protocol defines However, ia header and a payload. Every message needs to be sent with this specific format, with a 24 bytes header and its payload:

When you get a ping, send back a pong with the exact same Payload Data as the ping (for pings and pongs, the max payload length is 125). You might also get a pong without ever sending a ping; ignore this if it happens. Aug 02, 2017 SUBSCRIBE to see more of my Videos & hit that LIKE button to support the channel!Hello fellow coders!

“ping/pong frames” are used to check the connection, sent from the server, the browser responds to these automatically. there’s also “connection close frame” and a few other service frames. In the browser, we directly work only with text or binary frames. WebSocket .send() method can send either text or binary data. Socket.IO enables real-time, bidirectional and event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed.

WebSocket enables bidirectional, message-oriented streaming of text and binary data between client and server. It is the closest API to a raw network socket in the browser. A large number of online connections require the solution of interesting and sometimes ambiguous tasks. Here are a few techniques for performance optimization when it comes to Go and WebSockets.
