title: Is there a good query builder for Amazon's DynamoDB?
body: <p>I tracked down <a href="https://github.com/noppoMan/npdynamodb" rel="nofollow noreferrer">this package</a>. Generally it's pretty nice. But it seems to lack support for <a href="http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Expressions.ProjectionExpressions.html" rel="nofollow noreferrer">Projection Expressions</a>. What is your tool of choice for dynamodb in node/typescript?</p>
  
  <p>I'm not fan of the data mappers listed <a href="https://stackoverflow.com/a/23793071/592641">here</a> because they tend to wrap the table data, or are abandoned as projects.</p>
