React guides

These guides cover @pbvex/react, a React hook layer over @pbvex/client.

Topics

• Provider — PBVexProvider and PBVexContext.
• Hooks — useQuery, useQueryResult, useMutation, useAction, useSubscription, and usePBVexClient.
• Patterns — loading, error boundaries, skip, stable args, and cleanup.
• Testing — renderHook, PBVexProvider, and mock transports.

Core concepts

• One PBVexProvider provides a Client to the component tree.
• useQuery returns the latest query value or undefined while loading.
• useQueryResult returns the full { data, error, isLoading } state.
• Mutations and actions are stable callables returned by hooks.
• All subscriptions use useSyncExternalStore with a shared QueryStore.

Cross-links

• Underlying client behavior is documented in the client guides.
• Server-side concepts are in the core guides: Authoring functions, Schema, Authentication.
