A session store backend for [gin-contrib/sessions](https://github.com/gin-contrib/sessions/).

## Usage

Import it in your code:

```go

import "github.com/kjmkznr/gin-sessions-dynamodb"

```

## Basic Examples

[embedmd]:# (example/main.go go)

```go

package main

import (

	"github.com/aws/aws-sdk-go/aws"

	"github.com/aws/aws-sdk-go/aws/session"

	"github.com/aws/aws-sdk-go/service/dynamodb"

	"github.com/gin-contrib/sessions"

	"github.com/gin-gonic/gin"

	dynamodbstore "github.com/kjmkznr/gin-sessions-dynamodb"

)

func main() {

	r := gin.Default()

	sess, err := session.NewSession(&aws.Config{

		Region: aws.String("ap-northeast-1"),

	})

	if err != nil {

		panic(err)

	}

	ddb := dynamodb.New(sess)

	store := dynamodbstore.NewStore(ddb, "SessionTable", []byte("secret"))

	r.Use(sessions.Sessions("mysession", store))

	r.GET("/incr", func(c *gin.Context) {

		sess := sessions.Default(c)

		var count int

		v := sess.Get("count")

		if v == nil {

			count = 0

		} else {

			count = v.(int)

			count++

		}

		sess.Set("count", count)

		err := sess.Save()

		if err != nil {

			println(err.Error())

		}

		c.JSON(200, gin.H{"count": count})

	})

	r.Run(":8000")

}

```
