Apollo subscription update example

To run the server cd server and run yarn run dev or npm run dev.

To run the client cd client and run yarn start or npm start.

To see the subscriptions in action, use Apollo Dev Tools' GraphiQL editor to send a mutation to the server. If you don't have/want Apollo Dev Tools, you can also navigate to http://localhost:8080/graphiql and execute the mutation there.

Here is an example mutation:

mutation {
  changeName(personId: 1, name: "wasBEN") {
    id
    name
  }
}

After this executes in the client, where you saw "BEN" previously, it will now be "wasBEN".
