dynastore

AWS DynamoDB store for Gorilla Toolkit using AWS library. Includes support for DynamoDB's TTL feature.

Uses the official AWS library, github.com/aws/aws-sdk-go/aws

Installation

go get github.com/savaki/dynastore/...

Environment Variables

dynastore uses the common AWS environment variables:

AWS_DEFAULT_REGION or AWS_REGION
AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY

dynastore will also use AWS roles if they are available. In that case, only AWS_DEFAULT_REGION or AWS_REGION need be set.

Alternately, AWS settings can be specified using Options:

dynastore.AWSConfig(*aws.Config)
dynastore.DynamoDB(*dynamodb.DynamoDB)

Tables

dynastore provides a utility to create/delete the dynamodb table.

Create Table

dynastore -table your-table-name -read 5 -write 5

Delete Table

Use the -delete flag to indicate the tables should be deleted instead.

dynastore -table your-table-name -delete

Example

// Create Store
store, err := dynastore.New(dynastore.Path("/"), dynastore.HTTPOnly())
if err != nil {
  log.Fatalln(err)
}

// Get Session
session, err := store.Get(req, "session-key")
if err != nil {
  log.Fatalln(err)
}

// Add a Value
session.Values["hello"] = "world"

// Save Session
err := session.Save(req, w)
if err != nil {
  log.Fatalln(err)
}

// Delete Session
session.Options.MaxAge = -1
err := session.Save(req, w)
if err != nil {
  log.Fatalln(err)
}
