Google Assistant SDK: Node.js Client

Node.js idiomatic client for Google Assistant SDK (unofficial).

The Google Assistant SDK lets you add hotword detection, voice
control, natural language understanding and Google’s smarts to your devices.
Your device captures an utterance (a spoken audio request, such as
What’s on my calendar?), sends it to the Google Assistant, and receives a
spoken audio response in addition to the raw text of the utterance.

Quickstart

Before you begin

Some configuration steps are needed to make this library work correctly, for
example creating a Cloud Platform project, creating a device and generating
OAuth2 credentials. Please, follow
the Google Assistant Library for Python guide
to get started quickly.

Installing the client library

npm install --save nodejs-assistant

Using the client library

// Imports the Google Cloud client library
const {Assistant, AssistantLanguage} = require('nodejs-assistant');
// Your credentials
const credentials = require('path-to-your-credentials.json');
// Creates a client
const assistant = new Assistant(/* required credentials */ {
  type: 'authorized_user',
  client_id: credentials.client_id,
  client_secret: credentials.client_secret,
  refresh_token: credentials.refresh_token,
}, /* additional, optional options */ {
  locale: AssistantLanguage.ITALIAN, // Defaults to AssistantLanguage.ENGLISH (en-US)
  deviceId: 'your device id',
  deviceModelId: 'your device model id',
});
// Sends a text query to the assistant
assistant.query('Hi!')
  .then(response => {
    // response contains all the fields returned by the assistant, such as the text and audio
    console.log(`Response: ${response.text}`);
    // response.audio is a Buffer containing the audio response by the assistant
  })
  .catch(err => {
    console.error('ERROR: ', err);
  });

Head over the API docs for
