PersistGraphQL

A build tool and Apollo Client network interface for implementing GraphQL query whitelisting and persisted queries (v0.3.11, last release ~2017, no active maintenance). Scans source code for .graphql files and static GraphQL query strings, assigns each query a hash/ID, and produces a JSON mapping. Provides an Apollo Client network interface to send only the hash/ID instead of the full query string. Primarily useful for reducing bandwidth and enforcing query allowlists. Competes with tools like `persisted-query-lib` but is specific to Apollo Client's older architecture. Limited to statically analyzable queries; no support for dynamic queries. Ships TypeScript types.
