},

regex: /^application\/x-msgpack$/,
serializer: body => msgpack.encode(body)

const config = {

serializer: body => AwesomeMessage.encode(AwesomeMessage.create(body)).finish()

fastify.get('/request', { config }, function (req, reply) {
reply.send({pippo: 'pluto'})
})For each route, a SerializerManager is defined, which has both per-route and global serializer definitions.
The MIME type application/json is always handled by fastify if no serializer is registered for that MIME type.
If no default key is specified in configuration, all requests with an unknown Accept header will be replied to with a 406 response (a boom error is used).
