graphql-react | Full-Stack App With React , GraphQL , MongoDB , and Apollo | GraphQL library

I've cloned a repo from here and trying to explore AWS AppSync's subscription. My understanding is that if there is real-time updates to server data, client should expect to see some notification or updates or sorts, so what I did was:

1. running the app on a simulator

2. Open DynamoDB console and add the records manually.

I was expecting there is some notifications received on my app but there isn't, and if I refresh the app it will have the updated records? Am I understand the subscription wrongly?

I have a big problem to make a boilerplate for a complete react application using graphql (react-apollo) and material-ui. I trying a lot of shit, but i always as the same problem:

Warning: Prop "className" did not match. Server: "MuiSvgIcon-root-60 MuiListItemIcon-root-127" Client: "MuiSvgIcon-root-60 MuiListItemIcon-root-123"

if i'm logged (problem is come from the Drawer component visibly), and:

Warning: Did not expect server HTML to contain a

if i'm logout (the Drawer is not showing).

You can found the complete example here: https://github.com/CocoJr/docker-sf4-elasticsearch-graphql-react-express/tree/master/volumes/node

This is my server.js file: https://github.com/CocoJr/docker-sf4-elasticsearch-graphql-react-express/blob/master/volumes/node/src/server.js
