Actions on Google: Number Genie Sample using Node.js and Cloud Functions for Firebase

This guess a number game, called Number Genie, is an action for the Google Assistant.


This app uses the i18n-node library to provide responses in both French and English. The responses 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.
