amazon web services - DynamoDB, AWS, Node.js, newb -

-

i exploring dynamodb use in node.js project. package.json

{ "name": "generic-server", "version": "0.0.1", "private": true, "engines": {   "node": "0.11.x" }, "dependencies": {   "express": "3.3.4",   "jade": "1.1.5",   "aws-sdk": ">= 2.0.9" }

}

now logged aws account , created dynamodb table. , have in index.js

 var aws= require('aws-sdk');  aws.config.update({//1  accesskeyid: 'blabla',   secretaccesskey: 'blabla',  region: 'us-east-1'  });  var db = new aws.dynamodb({apiversion: '2014-12-04'});  db.listtables(function(err, data) { // 2     console.log(data);  });

so console.log of data null. can think of 2 areas might issue ( numbered them inline 1 or 2 ). appreciated.

i .net, java, , obj c developer playing node.js , aws, fyi.

the first parameter listtables "params" field , second 1 callback. you're passing callback "params". try this:

db.listtables({}, function (err, data) {//2
