Actions on Google: Number Genie Sample

This sample demonstrates Actions on Google features for use on Google Assistant, including how to steer conversation in a numeric guessing game through the use of localization (French and English), deep links, fallbacks, contexts, alongside rich responses -- using the Node.js client library and deployed on Cloud Functions for Firebase.

This Action uses the i18n-node library to provide responses in both French and English, which are listed in the locales directory. In each function execution, the strings.js setLocale() function is called to set the i18n-node locale based on the user locale in the incoming request. Prompts are then selected by i18n-node from the available languages, defaulting to en if the user's language is unavailable.

Setup Instructions

Prerequisites

  1. Node.js and NPM
    • We recommend installing using NVM
  2. Install the Firebase CLI
    • We recommend using version 6.5.0, npm install -g firebase-tools@6.5.0
    • Run firebase login with your Google account

Configuration

Actions Console

  1. From the Actions on Google Console, New project (this will become your Project ID) > Create project > under More options > Conversational
  2. From the top menu under Develop > Actions (left nav) > Add your first action > BUILD (this will bring you to the Dialogflow console) > Select language and time zone > CREATE.
  3. In the Dialogflow console, go to Settings ⚙ > Export and Import > Restore from zip using the agent.zip in this sample's directory.

Firebase Deployment

  1. On your local machine, in the functions directory, run npm install
  2. Run firebase deploy --project {PROJECT_ID} to deploy the function
    • To find your Project ID: In Dialogflow console under Settings ⚙ > General tab > Project ID.

Dialogflow Console

  1. Return to the Dialogflow Console > select Fulfillment > Enable Webhook > Set URL to the Function URL that was returned after the deploy command > SAVE.
    Function URL (dialogflowFirebaseFulfillment): https://${REGION}-${PROJECT_ID}.cloudfunctions.net/dialogflowFirebaseFulfillment
    
  2. From the left navigation menu, click Integrations > Integration Settings under Google Assistant > Enable Auto-preview changes > Test to open the Actions on Google simulator then say or type Talk to my test app.

Running this Sample

  • You can test your Action on any Google Assistant-enabled device on which the Assistant is signed into the same account used to create this project. Just say or type, “OK Google, talk to my test app”.
  • You can also use the Actions on Google Console simulator to test most features and preview on-device behavior.
