JavaScript@langchain/reactUseStreamReturnsubmit
Method●Since v1.0

submit

Dispatch a new run on the bound thread.

input is typed as Partial<StateType> so IDE autocompletion surfaces the state keys declared on the root hook. Pass null (or omit fields) when resuming an interrupt via options.command.resume — the server accepts a null payload in that case.

Copy
submit(
  input: WidenUpdateMessages<Partial<StateType>> | null | undefined,
  options: StreamSubmitOptions<StateType, ConfigurableType>
): Promise<void>

Parameters

NameTypeDescription
input*WidenUpdateMessages<Partial<StateType>> | null | undefined
