@michelfloyd There are a couple of things off the top of my head. Full disclosure, I'm a complete beginner and thus am only aware of the "buzz-words" surrounding GraphQL. So the relevance of my ideas to this series is ...... questionable to say the least. Anyhow, there's some:

• A deeper dive into queries (and maybe implement a basic API on client side using Apollo Client and Vue Hooks?)
• More about integrating typescript with GraphQL
• Authentication and error handling
• Adding tests
• Using subscriptions to access realtime data?
