Go WebSockets

Using WebSockets

Go WebSockets use gorilla/websocket for real-time apps.

Introduction to WebSockets in Go

WebSockets provide a full-duplex communication channel over a single TCP connection, allowing real-time data exchange between clients and servers. In Go, the gorilla/websocket package is a popular choice for implementing WebSocket functionality in applications. This tutorial will guide you through setting up a basic WebSocket server in Go using this package.

Installing Gorilla WebSocket

To use Gorilla WebSocket, you need to first install the package. You can do this using the go get command:

Creating a Basic WebSocket Server

Let's start by creating a basic WebSocket server. This server will listen for client connections and echo any messages it receives back to the client.

Testing the WebSocket Server

To test the WebSocket server, you can use a WebSocket client such as websocket.org's Echo Test. Connect to ws://localhost:8080/ws to see the echo functionality in action.

Handling Errors and Upgrading Connections

During the WebSocket upgrade process, various errors can occur. The Upgrade method returns an error if the upgrade fails. You should handle these errors gracefully in your application to ensure reliability.
