@orangecheck/agent-langgraph / graphStateHash

Function: graphStateHash()

function graphStateHash(state: Record<string, unknown>): string;

Defined in: index.ts:44

Compute a stable hash of a LangGraph state object. Use canonical JSON (RFC 8785) so reordered keys / repeated serializations produce the same hash. Returns sha256:<64-hex>.

Most LangGraph deployments persist the state object via a checkpointer (in-memory, postgres, redis, etc.). The state-hash here is over the checkpointer's serialized state at the moment the tool node fires.

Parameters

Parameter	Type
state	Record<string, unknown>

Returns

string
