熱編譯（Hot Compile）

Edit, save, and refresh. Revel compiles your code and templates for you, so you don't miss a beat. Code doesn't compile? It gives you a helpful description. Run-time code panic? Revel has you covered.

Simplicity Optional

Revel tries to provide a comprehensive toolkit for making everyday web apps.

Don't want to use some of the helpers? Revel gets out of the way and gives you direct access to the underlying request and response.

Blocking

Revel builds on top of the Go HTTP server, which runs each request in its own goroutine. Write simple blocking code without guilt.

以下是一個示例：

// app/controllers/app.go

type Application struct {
    *rev.Controller
}

func (c Application) Register() rev.Result {
    title := "Register"
    return c.Render(title)
}

func (c Application) SaveUser(user models.User, verifyPassword string) rev.Result {
    c.Validation.Required(verifyPassword).Key("verifyPassword")
    c.Validation.Required(verifyPassword == user.Password).Key("verifyPassword").
        Message("Password does not match")
    user.Validate(c.Validation)

    if c.Validation.HasErrors() {
        c.Validation.Keep()
        c.FlashParams()
        return c.Redirect(Application.Register)
    }

    _, err := c.Txn.Exec("insert into User (Username, Password, Name) values (?, ?, ?)",
        user.Username, user.Password, user.Name)
    if err != nil {
        panic(err)
    }

    c.Session["user"] = user.Username
    c.Flash.Success("Welcome, " + user.Name)
    return c.Redirect(Hotels.Index)
}
