Is there a way to disable hooks on specific route?

[yamalight]

I'm trying to setup auth as per example from fastify-auth:

fastify.addHook('preHandler', fastify.auth([fastify.verifyJWT]))

fastify.route({
  method: 'POST',
  url: '/auth-multiple',
  handler: (req, reply) => {
    req.log.info('Auth route')
    reply.send({ hello: 'world' })
  }
})

But I need to have a couple of routes that shouldn't trigger the auth preHandler on them.
Is there a way to disable this preHook for specific routes? Or maybe there's a different way of defining routes so that hook won't get executed?

Just register those routes in a different context:

fastify.register((instance, opts, next) => {
  // authenticated routes
  instance.addHook('preHandler', fastify.auth([fastify.verifyJWT])
  fastify.route(/*...*/)
})

fastify.register((instance, opts, next) => {
  // non-authenticated routes
  fastify.route(/*...*/)
})

@jsumners thanks!
would you be open to a docs PR that clarifies that in hooks section? currently that's only mentioned way below closer to the end, I think it'd be useful to mention the fact that hooks are scoped in the very beginning.

We are always receptive to PRs that improve documentation.

@jsumners PR open: #488
Does that looks OK?

Closing this.

i know this is old issue but i get same problem too, i solve with this

fastify.addHook("preHandler", async (request, reply) => {
  // some validation 
  return;
});

fastify.get(
  "/getaddress",
  {
    schema: {
      query: Joi.object()
        .keys({
          data1: Joi.string().required(),
        })
        .required()
    },
    validatorCompiler: ({ schema, params, method, url, httpPart }) => {
      return data => schema.validate(data);
    },
    preHandler: async (request, reply, done) => {
      // spesific validation
      return;
    }
  },

    },
    preHandler: async (request, reply, done) => {
      // spesific validation
      return;
    }
  },

this will invoke multiple hook functions instead skipping it.
