Example

import { createSamplingHandler, Gemini } from "@iqai/adk";

const llm = new Gemini("gemini-2.0-flash-exp");

// Example 1: Return full LlmResponse
const samplingHandler1 = createSamplingHandler(async (request) => {
  const responses = [];
  for await (const response of llm.generateContentAsync(request)) {
    responses.push(response);
  }
  return responses[responses.length - 1];
});

// Example 2: Return simple string
const samplingHandler2 = createSamplingHandler(async (request) => {
  const lastMessage = request.contents[request.contents.length - 1].parts[0].text;
  return await runner.ask(lastMessage);
});

// Example 3: Direct function reference
const samplingHandler3 = createSamplingHandler(runner.ask);
