WebAssembly+Vugu怎么快速构建single-pagewebapplication

// +build ignorepackage main
import (  "log"  "net/http"  "os"
  "github.com/vugu/vugu/simplehttp")
func main() {  wd, _ := os.Getwd()  l := "127.0.0.1:8844"  log.Printf("Starting HTTP Server at %q", l)  h := simplehttp.New(wd, true)  // 如果你有CSS文件，可以这样引用  // simplehttp.DefaultStaticData["CSSFiles"] = []string{ "/my/file.css" }  log.Fatal(http.ListenAndServe(l, h))}

// +build wasm
package main
import (  "log"  "os"
  "github.com/vugu/vugu")

func main() {
  println("Entering main()")  defer println("Exiting main()")
  rootInst, err := vugu.New(&Root{}, nil)  if err != nil {    log.Fatal(err)  }
  env := vugu.NewJSEnv("#root_mount_parent", rootInst, vugu.RegisteredComponentTypes())  env.DebugWriter = os.Stdout
  for ok := true; ok; ok = env.EventWait() {    err = env.Render()    if err != nil {      panic(err)    }  }
}//会被编译成.wasm后缀的文件(//+build wasm)
