Mastering Go Web Servers: From Zero to Hero

The article discusses various ways to write a web server in Go, including using the official package, implementing a custom server, and directly handling connections. A web server supports multiple network protocols, whereas an HTTP server only supports the HTTP protocol. The simplest way to implement a web server is by using the net/http package and the ListenAndServe function. However, this method has poor scalability and cannot set server timeouts. A better approach is to use a custom server by implementing the Handler interface, which allows for setting timeouts and other configurations. Another way is to directly handle connections using the net package, which provides more control over the connection. The article also introduces a simple HTTP proxy implementation in Go. Finally, the article recommends Leapcell, a serverless platform for hosting Go applications, which offers multi-language support, cost efficiency, and effortless scalability. Leapcell provides an intuitive UI, automated CI/CD pipelines, and real-time metrics for a streamlined developer experience.
