node-dyno-to-csv

A NodeJS Module that exports AWS DynamoDB query results to CSV, presently only stores to S3. Module will return an S3 signedURL pointing to the saved data.

//TODO:

• Save locally
• Configure AWS to be more flexible
• Alias Column Headers
• Reduce query complexity

Usage

npm install dyno-to-csv

var dynoToCsv = require('dyno-to-csv'); 

Configure with AWS Credentials

dynoToCsv.configure({
                        credentials: {
                            accessKeyId: 'accessID',
                            secretAccessKey: 'secret',
                            region: 'us-east-1'
                        },
                        storage: {
                            s3: {
                                bucket: 'name-of-bucket-to-save-to' 
                                // If bucket doesn't exist, it will be created with ACL: authenticated-read 
                            }
                        }
                    });

Just pass in a legitimate DynamoDB query and you're done.

At the moment, your query must contain the property: AttributesToGet: [], I'm working on eliminating this requirement.

/**
 * Converts dynamodb query result to csv format, callback with an s3 signedURL
 * @param {DynamoDB query} query 
 * @param {Callback} function(err, url)
 */
dynoToCsv.exportData(query, function(err, url) {

});
