Validating inputs and outputs only via typescript

Hey everyone,
I am trying to create an appRouter with ts-morph but I am having trouble with passing the 
zod
 schema/object instance to it (since I need to pass the original implementation, not the instance).
I was thinking about a way to work around this and was wondering if I could somehow just pass the zod typescript type in the inputs and outputs - keep in mind that my usecase only calls for the type definitions to work, not the actual implementation.

import { initTRPC } from '@trpc/server';
import { z } from 'zod';

const t = initTRPC.create();
const publicProcedure = t.procedure;

const randomSchema = z.object({
  name: z.string(),
});

type RandomType = z.infer<typeof randomSchema>;

const appRouter = t.router({
  UserRouter: {
    hello: publicProcedure.input<RandomType>().query((opts) => {
      const name = opts.input.name;
      return {
        greeting: `Hello ${opts.input.name}`,
      };
    }),
  },
});
export type AppRouter = typeof appRouter;


here you can see I am trying to pass on;y the RandomType, but ofc I don't really know what I am doing 😄
