The code described in the linked documentation has different types than the code that gRPC generates directly. It looks like there is a layer of wrapping code provided by Nest. So, even if we did have a TypeScript generator, it would not be directly useful to Nest users.

For a discussion of the challenges of providing a TypeScript generator in general, please see #528.
