Create a main.go file and copy-paste the following code snippets:

package main
import (
func main() {
app := iris.New()
// Configure sessions manager as we used to.
sess := sessions.New(sessions.Config{Cookie: "mysession_cookie_name"})
visitApp := mvc.New(app)


  • The VisitController.Session is automatically binded to the current sessions.Session.

  • The VisitController.StartTime is statically set to the server's start time with .Register(time.Now()) above.

type VisitController struct {
Session *sessions.Session
StartTime time.Time
func (c *VisitController) Get() string {
// it increments a "visits" value of integer by one,
// if the entry with key 'visits' doesn't exist
// it will create it for you.
visits := c.Session.Increment("visits", 1)
// write the current, updated visits.
since := time.Now().Sub(c.StartTime).Seconds()
return fmt.Sprintf("%d visit(s) from my current session in %0.1f seconds of server's up-time",
visits, since)


Open a terminal session and execute:

$ go run main.go
