Actions on Google Client Library

:warning: Warning: Conversational Actions will be deprecated on June 13, 2023. For more information, see Conversational Actions Sunset.

This client library makes it easy to create Actions for the Google Assistant and supports Dialogflow, Actions SDK (v2), and Smart Home fulfillment.

:warning: We now recommend using Actions Builder or the Actions SDK to develop, test, and deploy Conversational Actions. For Conversational Actions built using Actions Builder see the @assistant/conversation library.

NPM Version Build Status

Setup Instructions

Install the library with either npm install actions-on-google or yarn add actions-on-google if you use yarn.

Developer Preview

To support features under Developer Preview, the library has a special preview branch which can be installed using the @preview tag.

This is installed with either npm install actions-on-google@preview or yarn add actions-on-google@preview.

The preview tag will be kept up to date with every new version of the library.

You can use the Developer Preview version to experience exciting new features that we’re still testing to make sure we have the best developer experience, and help us providing feedback on the API design and feature set.

The APIs offered in Developer Preview have not matured to General Availability yet, which means:

Conversational Services

Dialogflow

// Import the appropriate service and chosen wrappers
const {
  dialogflow,
  Image,
} = require('actions-on-google')

// Create an app instance
const app = dialogflow()

// Register handlers for Dialogflow intents

app.intent('Default Welcome Intent', conv => {
  conv.ask('Hi, how is it going?')
  conv.ask(`Here's a picture of a cat`)
  conv.ask(new Image({
    url: 'https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/imgs/160204193356-01-cat-500.jpg',
    alt: 'A cat',
  }))
})

// Intent in Dialogflow called `Goodbye`
app.intent('Goodbye', conv => {
  conv.close('See you later!')
})

app.intent('Default Fallback Intent', conv => {
  conv.ask(`I didn't understand. Can you tell me something else?`)
})

Actions SDK

// Import the appropriate service and chosen wrappers
const {
  actionssdk,
  Image,
} = require('actions-on-google')

// Create an app instance
const app = actionssdk()

// Register handlers for Actions SDK intents

app.intent('actions.intent.MAIN', conv => {
  conv.ask('Hi, how is it going?')
  conv.ask(`Here's a picture of a cat`)
  conv.ask(new Image({
    url: 'https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/imgs/160204193356-01-cat-500.jpg',
    alt: 'A cat',
  }))
})

app.intent('actions.intent.TEXT', (conv, input) => {
  if (input === 'bye' || input === 'goodbye') {
    return conv.close('See you later!')
  }
  conv.ask(`I didn't understand. Can you tell me something else?`)
})

Actions SDK

Smart Home

// Import the appropriate service
const { smarthome } = require('actions-on-google')

// Create an app instance
const app = smarthome()

// Register handlers for Smart Home intents

app.onExecute((body, headers) => {
  return {
    requestId: 'ff36...',
    payload: {
      // ...
    },
  }
})

app.onQuery((body, headers) => {
  return {
    requestId: 'ff36...',
    payload: {
      // ...
    },
  }
})

Frameworks

Export or run for your appropriate framework:

Firebase Functions

const functions = require('firebase-functions')

// ... app code here

exports.fulfillment = functions.https.onRequest(app)

Dialogflow Inline Editor

const functions = require('firebase-functions')

// ... app code here

// name has to be `dialogflowFirebaseFulfillment`
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app)

Self Hosted Express Server

const express = require('express')
const bodyParser = require('body-parser')

// ... app code here

const expressApp = express().use(bodyParser.json())

expressApp.post('/fulfillment', app)

expressApp.listen(3000)

AWS Lambda API Gateway

// ... app code here

exports.fulfillment = app
