Examples of accessing DynamoDB using the AWS SDK in Golang and Node.js

Examples of accessing DynamoDB using the AWS SDK

Examples have been written in the following languagues...

1. Node.js (javascript)
   • http://docs.aws.amazon.com/amazondynamodb/latest/gettingstartedguide/GettingStarted.NodeJs.html
2. Golang (coming soon)
   • http://docs.aws.amazon.com/sdk-for-go/api/service/dynamodb/

Local vs Cloud DynamoDB

These examples write to a locally running DynamoDB instance (downloadable from AWS)...

• http://docs.aws.amazon.com/amazondynamodb/latest/gettingstartedguide/intro-dynamodb-local.html

Change the 'endpoint' in the AWS.config in each script to write the AWS cloud DynamoDB...

AWS.config.update({
   endpoint: "https://dynamodb.us-east-1.amazonaws.com"}
);
