Template for nextjs app using graphql with subscriptions

npm install
npm run dev
# or
yarn
yarn dev

Open a browser at http://localhost:3000 and create some items with "New Item" button. Then you can change the colors to some of them with "Change color" button.

Open a new browser at the same url as above and you will see the same list with items. That is result of GraphQL query which fetches the existing items from the DB. Now do some more changes on the list and check that the list is in sync with the first browser. That is result of GraphQL subscription which get fired on every created, updated or delete item.
