I think some error handling and tests outside the happy path would be beneficial.

Can you please also add a README section about auto scaling with an example and some useful links to AWS docs?

Move all the helper methods is inner functions of buildAutoScaling

is this considered superior design in JS/TS? because I see this as writing a big method in other programming languages, and I'm a firm believer in small methods. i understand that you are asking to make an inner function and not copy the code but and at the same time we want to ensure these methods are not called by anyone outside of buildAutoScaling. but since all these methods are private is that a high risk?
