AWS-SDK Wrapper

Wrapper for the aws-sdk package. Makes using the package easier.

Installation

$ npm install dynamodb-wrap

Be sure to have your AWS credentials in the ~/.aws/credentials file

Usage

var aws = require('dynamodb-wrap');

aws.initialize({region: 'us-west-2'});

var params = {
    table: 'my-table-name'
};

aws.scan(params, function(err, data){
    if(err){
        return console.log("Error found: " + err);
    }

    console.log(data);
});

Features

• Automated pagination. Scan implements full scan which will pull all table data. (Up to table throughput limits).
• If throughput is exceeded, the response will include a flag "maxReached" to indicate that not all items were retrieved.
• A sleep can be passed in to slow it down and possibly prevent exceeding the throughput. (ie. {sleep: 2000})
• Parameter keys are changed to a friendly lower case version (i.e ExpressionAttributeValues vs values)
• Data responses have the keys removed

{
    "myInteger": 1,
    "myString": "steve leon"
}

vs

{
    "myInteger": {
        "N": 1
    },
    "myString: {
        "S": "steve leon"
    }
}

• Key removal can be turned off by passing {raw: true} into the parameters.
