Sessions

Create a main.go file and copy-paste the following code snippets:
package main
​
import (
    "fmt"
    "time"
​
    "github.com/kataras/iris/v12"
    "github.com/kataras/iris/v12/mvc"
    "github.com/kataras/iris/v12/sessions"
)
​
func main() {
    app := iris.New()
​
    // Configure sessions manager as we used to.
    sess := sessions.New(sessions.Config{Cookie: "mysession_cookie_name"})
    app.Use(sess.Handler())
​
    visitApp := mvc.New(app)
    visitApp.Register(time.Now())
    visitApp.Handle(new(VisitController))
​
    app.Listen(":8080")
}
Controller
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)
}
Run
Open a terminal session and execute:
$ go run main.go
1.Prepare a client, e.g. your browser
2.navigate to http://localhost:8080​
3.refresh the page some times
4.close the browser
5.re-open the browser (if it wasn't in private mode) and re-play 2.
