Session for go consists of a way to preserve data across subsequent accesses in network related applications.

Feutures:

• Custom backends to store session data locally.
• Flash messages: session values that last until read.
• Low dependency and therefore versitile, for example, it does not depened on the go http pkg

Built-in backends to store sessions locally:

• storeMap ⬄ A in memory map[string]sessions store
• storeLeveldb ⬄ Stores session data in a leveldb

Simple Sample code the uses the default storeMap backend:

package main

import(
	"bitbucket.org/gotamer/net/session"
	"fmt"
)

func main(){
	id := save()
	load(id)
}

func save() string {
	sess := session.New()
	sess.Set("Alias","GoTamer")
	err := sess.Save()
	Check(err)
	fmt.Println("Session Saved", sess)
	sid, err := sess.Id()
	Check(err)
	return sid
}

func load(sid string){
	sess, err := session.Load(sid)
	Check(err)
	fmt.Println("Session Load: ", sess)
}

Sample code the uses the leveldb backend:

package main

import(
	"bitbucket.org/gotamer/net/session"
	"fmt"
)

var path = "/tmp/sessions"

func init(){
	session.StoreLeveldb(path)	
}

func main(){
	id := save()
	load(id)
}

func save() string {
	sess := session.New()
	sess.Set("Alias","GoTamer")
	err := sess.Save()
	Check(err)
	fmt.Println("Session Saved", sess)
	sid, err := sess.Id()
	Check(err)
	return sid
}

func load(sid string){
	sess, err := session.Load(sid)
	Check(err)
	fmt.Println("Session Load: ", sess)
}

Additional backends can be created by simply implementing following interfaces:

type Store interface {
	Save(session *sessionObject) (err error)
	Load(sid string) (session *sessionObject, err error)
	Delete(sid string) (err error)
}
