app.go is a simple web framework for use in Google AppEngine. Just copy the app folder to your working folder and import it from your main program. That's it. A web application ready to run in no time. Also, app.go comes with a powerful datastore manager to simplify your interactions with BigTable, making your code cleaner and safer.

Here is the Guestbook example from AppEngine rewritten using app.go

package hello

import(
    "app"
    "models"
)

func init() {
    app.Start()
    app.Get ("/index", index)
    app.Post("/sign" , sign )
}

func index(ctx app.Context) {
    recs := models.GetGreetings(ctx,10)
    ctx.Render("index",recs)
}

func sign(ctx app.Context) {
    rec := models.Greeting{
        Author : ctx.User.Nick,
        Content: ctx.GetValue("content"),
    }
    models.NewGreeting(ctx,rec)
    ctx.Redirect("/")
}

As you can see, with app.go we make it really easy to write web apps in go. We welcome your feedback for any special request or bug fix.

Enjoy!
