Is it possible to create a generic router to pass a type on?

Hi, I was wondering if it is possible to create a generic router to pass a type which is expected to return

Create a factory function. I've done this for CRUD entities which need all the same behaviour over a similar base type

function createCrudRouter<TEntity extends BaseEntity>(config: { entity: TEntity /* + inversion of control methods, etc  */ }) {
  return router({
    create: /* etc */,
    get: /* etc */,
    list: /* etc */,
    update: /* etc */,
    deleted: /* etc */,
  })
}

function createCrudRouter<TEntity extends BaseEntity>(config: { entity: TEntity /* + inversion of control methods, etc  */ }) {
  return router({
    create: /* etc */,
    get: /* etc */,
    list: /* etc */,
    update: /* etc */,
    deleted: /* etc */,
  })
}

In my case I'm doing this with a codegen'd client over a rest API, and so I had to come up with some selector methods to get the endpoint. For an ORM you can probably just pass the Entity class itself
