Stimulation Options

  • maxNeuronHops?: number — limit traversal depth
  • onResponse?: (response) => void | Promise<void> — tap into flow and completion (async supported)
  • abortSignal?: AbortSignal — graceful cancel
  • stimulationId?: string — custom id
  • allowName?: (collateralName: string) => boolean — filter collaterals
  • concurrency?: number — per-run concurrency limit
  • ctx?: ICNSStimulationContextStore — reuse context
  • createContextStore?: () => ICNSStimulationContextStore — custom store
const controller = new AbortController();
await cns.stimulate(signal, {
  maxNeuronHops: 10, // optional, disabled by default
  abortSignal: controller.signal,
  onResponse: r => {
    if (r.queueLength === 0) console.log('done');
  }
});

Async listeners and failure semantics​

  • Local onResponse and all global listeners (added via addResponseListener) can be synchronous or asynchronous.
  • They run in parallel for each response. If any throws or returns a rejected Promise, the current stimulate(...) Promise rejects.
  • If all listeners are synchronous, CNStra does not introduce extra async deferrals for that response.
// Async onResponse example (e.g., persist to DB/Redis)
await cns.stimulate(signal, {
  onResponse: async (r) => {
    if (r.outputSignal) {
      await repo.save(r.stimulationId, r.outputSignal);
    }
  }
});
