About the course

In this tutorial, we dive into real-time web communication using WebSockets in Go! We'll introduce the Gorilla WebSocket package, a high-performance and easy-to-use solution for implementing WebSockets in Golang. Follow along as we set up a simple yet powerful chat application, demonstrating bidirectional, low-latency communication between clients and servers.

We cover everything from installing the Gorilla WebSocket package, setting up a basic web server, to upgrading HTTP requests to WebSocket connections. Learn about handling incoming WebSocket messages and echo them back to the client. We also tackle common challenges like handling CORS errors and ensuring seamless communication. Whether you're new to Go or looking to enhance your real-time web application skills, this tutorial is perfect for you!
