• apollographql/apollo-client#2533

This template demonstrate multiple issues :

• An unhandled network error when unmounting a component that failed to fetch
• Undefined response in afterware for a network error (e.g. client offline or server crashed)
• Component can't render data after an error (stuck on error)

How it works

This template is using the Fake graphql server from : http://fake.graphql.guru/

You'll have to simulate an offline state (e.g with chrome developer tools -> Network), this is the same behavior as server offline or crashed.

The "New component with apollo" button calls a component with apolloClient HOC querying a random firstname

Steps to reproduce issues

• run yarn then yarn start (or npm install then npm run start)
• Go offline, click button to fetch then unmount the component to throw the error in console
• Go online then try to fetch/refetch, the component still displays error (but queries are sent and return data)
