Caveat: it still works best in a codebase that is already good. So while any one line of code is ephemeral, how is the overall codebase trending? Towards a bramble, or towards a bonsai?
If the software is small and not mission critical, it doesn’t matter if it becomes a bramble, but not all software is like that.
A good codebase depends on the business context, but in my case its an agile one that can react to discovered business cases. I’ve written great typed helpers that practically allow me to have typed mongo operators for most cases. It makes all operations really smooth. AI keeps finding cretaive ways of avoiding my implementations and over time there are more edge cases, thin wrappers, lint ignore comments and other funny exceptions. Whilst I’m losing the guarantees I built...
