How do I promisify the AWS JavaScript SDK?

Question

I want to use the aws-sdk in JavaScript using promises.

Instead of the default callback style:

dynamodb.getItem(params, function(err, data) {
  if (

This solution works best for me:

// Create a promise object
var putObjectPromise = s3.putObject({Bucket: 'bucket', Key: 'key'}).promise(); 

// If successful, do this:
putObjectPromise.then(function(data) {
 console.log('PutObject succeeded'); })

// If the promise failed, catch the error:
.catch(function(err) { 
console.log(err); });
