I'm calling DynamoDB's PutItem as my first es6 promises attempt on AWS Lambda with Node 4.3.
Here's the relevant code:
var req = d.putItem(params={
'TableName': TABLE,
...
}).promise();
req.then(function(resp) {
console.log("sresp", resp);
// I want to do more with the returned data here
});
And here's what shows up in the console:
sresp {}
There are a few questions about Promises in the AWS SDK (javascript) that are from the "pre-promises" era; as of March 2016 there's native support.
DynamoDB putItem
request doesn't return anything by default. You have to specify a value for one or more of the following parameters in order to get something back (they all default to NONE
):
ReturnConsumedCapacity: 'INDEXES | TOTAL | NONE',
ReturnItemCollectionMetrics: 'SIZE | NONE',
ReturnValues: 'NONE | ALL_OLD | UPDATED_OLD | ALL_NEW | UPDATED_NEW'
