Can I call tRPC procedure inside another procedure?

Something like this:

export const mainRouter = createTRPCRouter({
 create: privateProcedure   
    .mutation(async ({ ctx }) => {
     ...
     doSomething({someInput: ""}) // call doSomething here with inputs
    }),
 doSomething: privateProcedure
    .input(
      z.object({
        someInput: z.string(),
      })
    )
}

export const mainRouter = createTRPCRouter({
 create: privateProcedure   
    .mutation(async ({ ctx }) => {
     ...
     doSomething({someInput: ""}) // call doSomething here with inputs
    }),
 doSomething: privateProcedure
    .input(
      z.object({
        someInput: z.string(),
      })
    )
}

You may need to call your procedure(s) directly from the same server they're hosted in, router.createCaller() can be used to achieve this.

what you probably want to do is extract the shared logic to a function you can call from both procedures
