AWS Doable Style

The AWS framework for Node has been around for a while, and for such reasons probably have to live with backward compatibility. One of the things that has annoyed me with the API is the usage of callbacks. I mean, that’s all fine, but many people these days problably want to use promises and async / await instead. Turns out that’s not very difficult.

They’ve added support for that by putting a .promise() function on the returned value. See code of the day for an example.

Code of the Day

await s3Client.createBucket(
    {
      Bucket: bucketName
    }
).promise();

Simply don’t give a callback and just call .promise() instead.
