What is the best way to define schema for path parameter in @hono/zod-openapi?

[mikan3rd]

For example, suppose I want to specify a numeric id as a path parameter.

If I do z.number() with @hono/zod-openapi, the OpenAPI schema will be numeric as expected, but the actual path parameter will be passed a string id, so I get a validation error.

Next, if I do z.string(), it does not result in a validation error, but the OpenAPI schema also results in the id being a string. Also, it is possible to specify a non-numeric value.

Furthermore, if I set z.coerce.number(), the OpenAPI schema will be numeric and there will be no validation error, but "required": false will be set even though it is required.

Finally I tried defining it as follows, is there a smarter way?
Also, is there a better way to inherit the schema from createSelectSchema in drizzle-zod?

import { z } from "@hono/zod-openapi";

z.object({
  id: z.string().pipe(z.coerce.number().int().positive()).openapi({
    example: "1",
    type: "integer",
    format: "int64",
  }),
});
