The alias must point at a built bot version (see BotVersion).

Conversing with a Bot

Recognize Text

// init
const recognizeText = yield* AWS.LexV2.RecognizeText(alias);

// runtime
const reply = yield* recognizeText({
  localeId: "en_US",
  sessionId: "user-123",
  text: "hello",
});
const intent = reply.sessionState?.intent?.name;

Wire into a Lambda Function

// Bind the alias in the init phase, call in the handler, and provide
// the RecognizeTextHttp layer on the Function's init Effect.
export default ChatFunction.make(
  { main: import.meta.url, url: true },
  Effect.gen(function* () {
    const alias = yield* AWS.LexV2.BotAlias("Live", {
      botId: version.botId,
      botVersion: version.botVersion,
    });
    const recognizeText = yield* AWS.LexV2.RecognizeText(alias);
    return {
      fetch: Effect.gen(function* () {
        const reply = yield* recognizeText({
          localeId: "en_US",
          sessionId: "user-123",
          text: "hello",
        });
        return HttpServerResponse.json({
          intent: reply.sessionState?.intent?.name ?? null,
        });
      }),
    };
  }).pipe(Effect.provide(AWS.LexV2.RecognizeTextHttp)),
