How to use the server?

The server can only be used if your server supports TLS. Then, you can call ConfigureServer.

package main

import (
	"github.com/valyala/fasthttp"
	"github.com/dgrr/http2"
)

func main() {
    s := &fasthttp.Server{
        Handler: yourHandler,
        Name:    "HTTP2 test",
    }

    http2.ConfigureServer(s, http2.ServerConfig{})
    
    s.ListenAndServeTLS(...)
}

How to use the client?

The HTTP/2 client only works with the HostClient.

package main

import (
        "fmt"
        "log"

        "github.com/dgrr/http2"
        "github.com/valyala/fasthttp"
)

func main() {
        hc := &fasthttp.HostClient{
                Addr:  "api.binance.com:443",
        }

        if err := http2.ConfigureClient(hc, http2.ClientOpts{}); err != nil {
                log.Printf("%s doesn't support http/2\n", hc.Addr)
        }

        statusCode, body, err := hc.Get(nil, "https://api.binance.com/api/v3/time")
        if err != nil {
                log.Fatalln(err)
        }

        fmt.Printf("%d: %s\n", statusCode, body)
}
