    Safely setState on a Mounted React Component through the useEffect Hook

    reactReact
    ^16.7.0-alpha

This is because our graphql client library is unable to cancel in-flight requests. Let's make that same kind of thing work by tracking the mounted state of our component using the useRef and useEffect hooks.
