Type●Since v1.6

ResolveStreamOptions

Resolves the appropriate options interface based on the agent/graph type.

This type automatically selects the correct options interface based on the type of agent or graph:

  1. DeepAgent → UseDeepAgentStreamOptions

    • Includes: filterSubagentMessages option
  2. ReactAgent → UseAgentStreamOptions

  3. CompiledGraph / Default → UseGraphStreamOptions

Copy
ResolveStreamOptions: IsDeepAgent<
  T
> extends true  UseDeepAgentStreamOptions<InferStateType<T>, Bag> : IsReactAgent<T> extends true  UseAgentStreamOptions<InferStateType<T>, Bag> : UseStreamOptions<InferStateType<T>, Bag>

Example

Copy
// Only DeepAgent options include filterSubagentMessages
type DeepOptions = ResolveStreamOptions<typeof deepAgent, BagTemplate>;
// DeepOptions.filterSubagentMessages exists

type AgentOptions = ResolveStreamOptions<typeof reactAgent, BagTemplate>;
// AgentOptions.filterSubagentMessages does NOT exist
