Issue with Generic Handler Factory for TanStack Start Routes
I'm trying to create a reusable handler factory pattern for TanStack Start API routes
The Problem: The RouteMethodHandlerCtx type requires 5 generics, including a specific route path as the 3rd generic parameter (e.g., '/demo/api/endpoint-factory'). When I try to make my factory generic to work with any route, I can't properly type the route path parameter.
What I'm trying to achieve: A reusable handler factory that:
- Works with any TanStack Start API route
- Maintains full type safety
How can I properly type the generic constraints for RouteMethodHandlerCtx to make this factory pattern work across different routes while maintaining type safety?
Prepared this example to give you an idea of what I am trying to build. The factory works when I hardcode the exact route path, but then it's not reusable across different routes. I need it to be generic
