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 I have outdated npm modules I can't upgrade because they are ESM only, and I have old modules that will likely never update.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.

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.
