What HTTP servers have you used in Go?

In Go, the standard HTTP server is the net/http package, which I used for most projects. It is simple to use, integrates well with other libraries, and allows for quick creation of REST APIs.

Additionally, for more performance-critical or specific tasks, server frameworks are used, such as:

• fasthttp — an alternative HTTP server with high performance but a less convenient API.
• gin — a framework on top of net/http with convenient routing and middleware.

Example of a simple HTTP server using net/http:

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, Go HTTP server!")
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

Overall, the choice of server depends on performance requirements and development convenience.
