Uptodate AWS API Gateway + Typescript or JavaScript exampe

Hi all!
I want to make a small backend for a Browser-App using API Gateway and found this example https://github.com/serverless/examples/blob/master/aws-node-typescript-rest-api-with-dynamodb
However, it is two years old, doesn’t use the latest AWS libs with types, also doesn’t use Promises and somehow the Lambda function isn’t even created when I run “serverless deploy”. It only creates an S3 Bucket and a Cloudformation Stack with only that Bucket. No function, no API Gateway. So I wanted if there is a more uptodate example that could actually work out of the box and use “current technologies” like promises and recent AWS SDK versions.
thanks in advance for any pointers,
