CreateEvent

Source: src/AWS/BedrockAgentCore/CreateEvent.ts

Records an interaction event into a memory’s short-term store.

Bind a Memory inside a function runtime to get a callable that appends conversational turns (or binary blobs) to an actor’s session. Provide AgentCore.CreateEventHttp on the Function effect to implement the binding over the AgentCore data-plane API.

Recording Events

import * as AgentCore from "alchemy/AWS/BedrockAgentCore";

export default MyFunction.make(
  { main: import.meta.url, url: true },
  Effect.gen(function* () {
    const memory = yield* AgentCore.Memory("AgentMemory", {
      eventExpiryDuration: "30 days",
    });

    // init
    const createEvent = yield* AgentCore.CreateEvent(memory);

    return {
      fetch: Effect.gen(function* () {
        // runtime
        const result = yield* createEvent({
          actorId: "user-1",
          sessionId: "session-1",
          eventTimestamp: new Date(),
          payload: [
            {
              conversational: {
                role: "USER",
                content: { text: "My favorite color is teal." },
              },

          ],
        });
        return HttpServerResponse.json({ eventId: result.event.eventId });
      }),
