Queries
Core queries in Arc are the low-level TypeScript and JavaScript primitives used to retrieve data from backend query endpoints. Ordinary queries use HTTP request and response semantics; observable queries subscribe to an emitting backend source. Neither requires Chronicle.
This section focuses on contracts and runtime behavior in @cratis/arc. For React hook-based usage, see React Queries.
