Serializing Preloaded Queries

[roduyemi]

Hi Relay team 🤗

We're using Relay for streaming SSR with React and Tanstack Router and I wanted to check whether the guidance in the Relay examples repo is still considered the recommended approach.

In issue-tracker-next-v13, the following helpers are used to ensure preloaded query references are serializable from server → client during streaming / partial hydration:

loadSerializableQuery.ts
https://github.com/relayjs/relay-examples/blob/main/issue-tracker-next-v13/src/relay/loadSerializableQuery.ts

useSerializablePreloadedQuery.ts
https://github.com/relayjs/relay-examples/blob/main/issue-tracker-next-v13/src/relay/useSerializablePreloadedQuery.ts

1. Are these helpers still the recommended / best-practice way to ensure preloaded query references are serializable when streaming?

2. With newer Relay releases and ongoing RSC / streaming support, is there a more modern or preferred pattern for handling this use case?

If so, is there documentation or an example that reflects the current recommended approach?

Thanks a lot for any clarification you can provide!
