Formatting DynamoDB data to normal JSON in AWS Lambda

Question

I\'m using AWS Lambda to scan data from a DynamoDB table. This is what I get in return:

{
  \"videos\": [
    {
      \"fil         


        

Answer 1

I know is a bit old but I had the same problem processing stream data from dynamoDB in node js lambda function. I used the proposed by @churro

import sdk and output converter

var AWS = require("aws-sdk");
var parse = AWS.DynamoDB.Converter.output;

use the parse function with a small hack

exports.handler = function( event, context, callback ) {
  var docClient = new AWS.DynamoDB.DocumentClient();
  event.Records.forEach((record) => {
        console.log(record.eventID);
        console.log(record.eventName);
        console.log('DynamoDB Record:', parse({ "M": record.dynamodb.NewImage }));
    });
  callback(null, `Successfully processed ${event.Records.length} records.`);
}

Hope it helps
