Server-Side Rendering and Live Queries
TanStack Start routes render on the server for the first pageload of a browsing session. Neither the React Query nor standard Convex useQuery()
hooks kick off requests for this data during this initial SSR pass, but the React Query hook useSuspenseQuery()
does. The React Query client is then serialized with whatever data was loaded to make it available in the browser at hydration time. This reduces rendering on the server and updating on the client from two steps to one step: isomorphic data fetching with a single hook.

and useQuery()

1const { data } = useSuspenseQuery(convexQuery(2 api.messages.listMessages,3 { channel: "chatty" }4))
1const { data, isPending } = useQuery(convexQuery(2 api.messages.listMessages,3 { channel: "chatty" }4))
On the browser these queries resume their subscriptions which you can see by .
Another way to opt into server-side data loading is to load the query in a loader.
