schemafy VS ts-rs

then use https://github.com/Marwes/schemafy to go json schema -> Rust

Schemafy.

Going the other way is also possible using schemafy but I never needed that so far.

I agree, and disagree.

I agree that it limits the usage of the tool in a polygot environment. I disagree it's a downside.

The absence of an intermediary language does give some benefits to the first class citizen (in this case, Typescript).

However, there are some other developments [1] which attempt to make the Typescript type system an IDL to allow for better interop.

Not the person you asked, but I’ve seen people use https://github.com/Aleph-Alpha/ts-rs to generate TS interfaces at compile time for use on the frontend. Saves a bunch of time when scaffolding up a new data model without having to use a custom gRPC plugin or something wonky like that. That makes Rust and TS a pretty powerful pairing IMO.

Does anyone know how mature ts-rust is? I'm trying to use this with complex types (nested enums etc) and am running into some pain-points, especially when I have types defined across multiple files. Not sure if this is a legitimate limitation, or whether there's just more for me to do in terms of configuration etc.
