[Bug?]: Orphaned Apollo Client on `RedwoodApolloProvider` re-render

justinadkins commented 1 month ago

What's not working?

With how the provider is currently constructed, a parent re-render will orphan an apollo client instance and create a new one. I believe this causes a memory leak and cache orphaning. I discovered it because of client pollution visible when using Apollo Client's dev tools.

This is due to the lack of memoization where the client is instantiated here.

How do we reproduce the bug?

Force a re-render of a parent of the RedwoodApolloProvider, for example App. Using the Apollo Client devtools, observe a new client instantiation each render.

What's your environment? (If it applies)

@justinadkins Are you thinking of using WeakRef to hold the the instance?

@callingmedic911 Just seeing this now, I hadn't considered using WeakRef. I submitted a PR #11699 if you'd like to take a look. I'm jus using a local variable to keep track of the current instance.
