I've added some commented out config params in serverless.yml file (what I generally end up using).
The handler.ts is also has middy goodies to help you out with the not so fun events object.
Everything is pretty much stock. Comes with 4 scripts: cz (commitizen), build, deploy and destroy.
The build depends on serverless-bundle plugin. I've also added the serverless-offline plugin if you are into that.
Feel free to open a issue in case you have any suggestions or doubts.
