How do I promisify the AWS JavaScript SDK?
The 2.3.0 release of the AWS JavaScript SDK added support for promises: http://aws.amazon.com/releasenotes/8589740860839559
I believe calls can now be appended with .promise() to promisify the given method.
You can see it start being introduced in 2.6.12 https://github.com/aws/aws-sdk-js/blob/master/CHANGELOG.md#2612
You can see an example of it's use in AWS' blog https://aws.amazon.com/blogs/compute/node-js-8-10-runtime-now-available-in-aws-lambda/
let AWS = require('aws-sdk');let lambda = new AWS.Lambda();exports.handler = async (event) => { return await lambda.getAccountSettings().promise() ;};
You can use a promise library that does promisification, e.g. Bluebird.
Here is an example of how to promisify DynamoDB.
var Promise = require("bluebird");var AWS = require('aws-sdk');var dynamoDbConfig = { accessKeyId: process.env.AWS_ACCESS_KEY_ID, secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY, region: process.env.AWS_REGION};var dynamoDb = new AWS.DynamoDB(dynamoDbConfig);Promise.promisifyAll(Object.getPrototypeOf(dynamoDb));Not you can add Async to any method to get the promisified version.
