A simple DynamoDB client module that allows you to override the endpoint using an environment variable.

DynamoDB::Client

A simple DynamoDB client module that allows you to override the endpoint using an environment variable.

Installation

Add this line to your application's Gemfile:

gem 'dynamodb-client'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dynamodb-client

Usage

Once the gem is included in your project. Ensure that you have the below environment variables set:

  AWS_ACCESS_KEY_ID=development
  AWS_SECRET_ACCESS_KEY=development
  AWS_REGION=us-east-1
  AWS_DYNAMODB_ENDPOINT=http://locahost:8000

By default, the amazon SDK provides AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_REGION but their SDK does not allow you to override the endpoint, this little gem lets you set the endpoint.

In your code you have 3 options:

require 'dynamodb/client'

class MyClass
  include DynamoDB::Client

  def my_method
    dynamodb_client.list_tables
  end
end

require 'dynamodb/client'

class MyClass
  extend DynamoDB::Client

  def self.my_method
    dynamodb_client.list_tables
  end
end

require 'dynamodb/client'

class MyClass
  def my_method
    DynamoDB::Client.instance.list_tables
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
