Question

In Go, how can I start the browser AFTER the server started listening ?
Preferably the simplest way possible.

My code so far, super dumbed down to the point:<

The API is not absolutely terrible, but let's just say "It takes some getting used to". Here is how you use custom attributes on the Server struct:

s := &http.Server{
    Addr:           cnf.API_SERVER_ADDRESS,
    Handler:        h,
    ReadTimeout:    0, // 1 * time.Minute,
    WriteTimeout:   30 * time.Minute,
    MaxHeaderBytes: 1 << 20,
}

go func() {

    l, err := net.Listen("tcp", cnf.API_SERVER_ADDRESS)

    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(`{"server_state":"listening"}`)
    log.Fatal(s.Serve(l));
}()

because if you instead use:

http.Serve(l, handler)

then you can't define custom properties on the server
