Type sharing between Deno server and Expo app not working
Hi all! 👋
I'm trying to share tRPC types between a Deno server and an Expo React Native app in a monorepo. My Deno server exports a fully-typed AppRouter for its tRPC routes, and I want the Expo client to import that type directly so that any changes in the backend are immediately reflected in the client's type checking. However, while everything works at runtime, TypeScript in the Expo client resolves the imported AppRouter as any, which means I'm not catching type errors as expected.
I really wanted to give Deno a try, but if I can't resolve this issue, I might have to consider migrating to Node. Has anyone encountered this problem or found a workaround?
Thanks in advance!
