Hi everyone,

A quick post on how to parse DynamoDB items into something more readable when using lambda with Node.js:

Original:

console.log(data["Item"]);

{
    CatBreedId: { S: '17acbc81-2b4a-462b-be87-bcc49580b1ae'},
    Name: { S: 'Cat #1'}
}

Parsed:

console.log(AWS.DynamoDB.Converter.unmarshall(data["Item"]));

{
    "CatBreedId": "17acbc81-2b4a-462b-be87-bcc49580b1ae",
    "Name": "Cat #1"
}

Official doco is here: https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB/Converter.html
