I’ve heard the shared code argument before, but in practice the only shared code I’ve really ever seen used is shared type definitions. Now shared type definitions are huge, but they’re a solved problem using JSON schema, GraphQL, or some other interface definition language that don’t necessarily require the same language in the front end and backend.

I have a nodejs+typescript backend stuck in a limbo state because of the whole esm modules fiasco. I have outdated npm modules I can't upgrade because they are ESM only, and I have old modules that will likely never update.

It's to the point where I will only be using golang for backends moving forward.
