Dialogflow Firestore Sample

This sample demonstrates how to connect Dialogflow to the Firestore database.
Dialogflow parses users' requests and sends requests to Firebase function indicating whether it should add or retrieve an entry from the Firestore database. The Firebase function queries the database to add or retrieve the entry and then compiles the proper response to the user. You can speak to your Dialogflow agent and tell it to write something to the database or retrieve it.
The sample will save what you tell it to save into the database as well as retrieve the value you store previously.
When you speak to your Dialogflow agent a webhook call is sent to Firebase functions which talks to the Firestore database to retrieve or add a entry as see below:

This sample is meant to be a starting point for anyone looking to connect a database to their Dialogflow agent and can be expanded to store users preferences, retrieve relevant data from your systems or enable your users to collaborate via chat/voice.

Dialogflow → Webhook Request → Firebase Function → Firestore Database
