TypeScript samples

The TypeScript samples wrap Sui gRPC and GraphQL endpoints in small production-shaped clients. They cover SuiGrpcClient, SuiGraphQLClient, transaction submission, transaction simulation, and checkpoint subscriptions.

The client code sets per-request deadlines, preserves checkpoint cursors for streams, and keeps transaction bytes opaque so signing remains outside the node process.

warning

Do not put private keys in node API samples or server environment variables. Sign transactions in a dedicated wallet/key-management boundary and send only serialized transaction bytes plus signatures to the submission path.
