How do I serve on HTTP/2 with Gin in Go?

To serve your Gin application over HTTP/2, you will first need to ensure that your server is set up properly. Below is a basic example of setting up a Gin server with HTTP/2 support.


    package main

    import (
        "log"
        "net/http"
        "github.com/gin-gonic/gin"
        "golang.org/x/net/http2"
    )

    func main() {
        router := gin.Default()

        router.GET("/", func(c *gin.Context) {
            c.JSON(http.StatusOK, gin.H{"message": "Hello, HTTP/2!"})
        })

        server := &http.Server{
            Addr:    ":8080",
            Handler: router,
        }

        http2.ConfigureServer(server)

        log.Println("Serving on https://localhost:8080")
        log.Fatal(server.ListenAndServeTLS("server.crt", "server.key"))
    }
