Fixes issue #14
Detailed explanation here:
https://stackoverflow.com/questions/49118378/apollo-mutate-calling-update-four-times-for-a-single-mutation
Mutation update event is triggered 4 times instead of 2 for each mutation causing duplication.
This can be handled by setting
disableOffline: true(see here https://docs.aws.amazon.com/appsync/latest/devguide/building-a-client-app-react.html#offline-settings)I've also updated the code that handled duplication since it is only required in
NewComment.jsandEventComments.js.I'm not sure if there is a better way of fixing this issue using some kind of
AppSyncconfiguration while avoidingdisableOffline: true.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
