How to add options or middleware calls per route? Does this work with hooks?

E.g. need to pass options for an auth-Route with rate limit (https://github.com/fastify/fastify-rate-limit)
Need to add addtional middlewares to a specific route.
I did not find anything in the docs or src/tests about that.

Example from fastify-rate-limit

fastify.get('/public/sub-rated-1', {
  config: {
    rateLimit: {
      timeWindow: '1 minute',
      allowList: ['127.0.0.1'],
      onExceeding: function (request, key) {
        console.log('callback on exceededing ... executed before response to client')
      },
      onExceeded: function (request, key) {
        console.log('callback on exceeded ... to black ip in security group for example, request is give as argument')
      }
    }
  }
}, (request, reply) => {
  reply.send({ hello: 'from sub-rated-1 ... using default max value ... ' })
})

How can this be done with a fastify.zod.post?

I acknowledge we should definitely support this, however, I am a not sure yet how exactly. If it's only passing a config object it's relatively easy, however we probably want to strongly type hooks as well (i.e. make sure the "request" parameter is consistently typed).

I have to think about it, but if you have ideas, I am open to suggestions.

After a brief look at the code this looks fairly straightforward to me.

fastify-zod/src/FastifyZod.ts

Lines 302 to 319 in 6ab9add

	f[method]<{
	Params: SchemaTypeOption<M, P>;
	Body: SchemaTypeOption<M, B>;
	Querystring: SchemaTypeOption<M, B>;
	Reply: SchemaTypeOption<
	M,
	R | (Rx extends Record<number, unknown> ? Rx[number] : never)
	>;
	}>(
	url,
	{
	schema: {
	...customSchema,
	...fastifySchema,
	},
	},
	handler as RouteHandlerMethod,
	);

Right here you're constructing a fastify route with the given method. If you'd spread the remaining arguments of RouteShorthandOptions (excluding schema since you use it's parameters individually in options) as arguments of addRoute, you could basically just spread them out next to the schema options and be done.

I'll make a PR.
