Once you suss out working with local shared dependencies, Serverless framework with typescript is pretty awesome. If I were starting a new project today I'd have to take a good hard look at this for my API back-end.

- Lambda Authorizers for token auth (or use the built-in stuff if you can get away with it)

- Lambda w/ API Gateway for individual endpoints

- Aurora for relational dbms

It's really a nicely put together ecosystem.
