Using web.go on Google App Engine

In short, if you want to use web.go in Google App Engine's Go runtime environment, check out my google-app-engine branch of web.go. Using that one you can start using web.go like this:

package webgoexample

import (

var server *web.Server

func init() {
    server = &web.Server{
        Config: web.Config,
        Logger: log.New(os.Stdout, "", log.Ldate|log.Ltime)}
    server.Get("/", func(ctx *web.Context) {
        ctx.Write([]uint8("Hello from web.go!"))

    // Send all requests to web.go.
    http.HandleFunc("/", handler)

func handler(writer http.ResponseWriter, request *http.Request) {
    server.ServeHTTP(writer, request)

BTW, if you simply put the web.go branch in your root dir, you have to remove the examples/ directory, otherwise App Engine won't be able to compile your project.

The branch in question has quite minimal changes to web.go, but I haven't proposed to merge it to trunk yet, since it removes some functionality. First of all I changed it not to set up /debug/ paths, so that I could remove the use of http/pprof, since it's not available on App Engine. After that I had to also remove the use of net.ResolveTCPAddr, which is also not available on App Engine. I basically replaced it with net.SplitHostPort, which I suspect is good enough. It doesn't resolve host names and port names, but I'd be surprised if hr.RemoteAddr wouldn't be an IP address and a port number.
