AWS Amplify Lex V2 Provider

Dependencies

Peer Dependencies

• Your project must provide @aws-amplify/core@^4.0.0

    yarn add @aws-amplify/core@^4.0.0

Config

Bot config

Must provide bot configuration with:

• botId: string Lex V2 bot's id
• botAliasId: string Lex V2 bot's alias id
• localeId: string Lex V2 bot's locale id
• region: string Lex V2 bot's region
• providerName: 'AWSLex2Provider' Must always be AWSLex2Provider

Add the provider to Amplify

import { Interactions } from '@aws-amplify/interactions';

Interactions.addPluggable(new AWSLex2Provider());

Config Example

// index.tsx
import { Amplify } from '@aws-amplify/core';
import { Interactions } from '@aws-amplify/interactions';
import AWSLex2Provider from '@thefat32/aws-amplify-lex-provider-v2';
import awsmobile from 'aws-exports'

Interactions.addPluggable(new AWSLex2Provider());

Amplify.Logger.LOG_LEVEL = 'DEBUG';
Amplify.configure({
  ...awsmobile,
  bots: {
    ['myBotName']: {
      botId: 'myBotId',
      botAliasId: 'myBotAliasId',
      localeId: 'myBotLocaleId',
      region: 'us-east-1',
      providerName: 'AWSLex2Provider',
    },
  },
});

Usage

Now you can use Interactions.send() with your Lex V2 bot

Interactions.send() will return either RecognizeTextCommandOutput or RecognizeUtteranceCommandOutput from @aws-sdk/client-lex-runtime-v2

Example

await Interactions.send('myBot', 'User input text') // will return RecognizeTextCommandOutput

await Interactions.send('myBot',{ content: 'User input text', options: { messageType: 'text' } }); // will return RecognizeUtteranceCommandOutput

const voiceData: Blob | ReadableStream = getUserVoiceInput(); // voice data must be either Blob or ReadableStream
await Interactions.send(voiceData ,{ content: text, options: { messageType: 'voice' } }); // will return RecognizeUtteranceCommandOutput
