Head to the AWS documentation page and download a version of DynamoDB into the project directory. To recap today’s short post, we set up a simple way to run DynamoDB locally from a simple project and then explored the NoSQL Workbench and did a basic GetItem request to show how we can connect up our local DynamoDB.
