Using WebSockets in Golang

In the digital era, the demand for instantaneous information processing has prompted the adoption of WebSockets, a communication protocol introduced in 2008, which facilitates real-time applications by enabling full-duplex communication over a single Transmission Control Protocol (TCP) connection. Unlike traditional HTTP polling methods that incur delays, WebSockets allow both server and client to transmit and receive data simultaneously, reducing overhead and enhancing user experience. The article provides a comprehensive guide on implementing a to-do app using WebSockets with the Go programming language, detailing the setup of an HTTP server, initiating WebSocket handshakes, and managing tasks within the app. It highlights the efficiency of WebSockets in maintaining long-term connections and their versatility across various platforms and applications, such as real-time messaging, multiplayer gaming, and collaborative tools. The article also emphasizes the simplicity of integrating WebSockets with Go to significantly improve application performance.
