Additional information to response logs

It is possible to add custom information to request completed logs. In your handler, or in a hook (before the onResponse hook which write the response log), you could add to the fastify reply object an additionalRequestCompletedLogInfo field. This field must be an object, and will be added to the request completed log.

For example:

fastify.post('/items/:itemId', {
  onRequest: function (req, reply, done) {
    reply.additionalRequestCompletedLogInfo = {
      custom: 'property',
    }
    done()
  }
}, function handler(request, reply) {
  reply.send({ created: 'true' })
})
