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"
)
funcmain() {
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"
)
funcmain() {
hc:=&fasthttp.HostClient{
Addr: "api.binance.com:443",
}
iferr:=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")
iferr!=nil {
log.Fatalln(err)
}
fmt.Printf("%d: %s\n", statusCode, body)
}
