title: AWS Lambda function write to S3
body: <p>I have a Node 4.3 Lambda function in AWS. I want to be able to write a text file to S3 and have read many tutorials about how to integrate with S3. However, all of them are about how to call Lambda functions after <a href="http://docs.aws.amazon.com/lambda/latest/dg/with-s3.html" rel="noreferrer">writing to  S3</a>.</p>
  
  <p>How can I create a text file in S3 from Lambda using node? Is this possible? Amazons documentation doesn't seem to cover it.</p>
