Type-first routing is a game changer 🌅

this is the configurator i was working on 👀

it basically lets you define your high level choices (linter, formatter, categories of lint rules, etc). then the rest is generated in an opinionated way, and you're given the config files that were emitted

In a small side project, you might get away with it.
You change a Lambda function, deploy it, and everything is fine.
