Getting started

  • Create a project at Firebase.com
  • firebase init

Configure firebase

Install Firebase tools:

$ npm install -g firebase-tools

Instantiate your project:

$ firebase init functions

Don't overwrite existing package.json and index.js

App/MQTT Configuration

You will have to configure a handful of firebase config vars.

  • firebase functions:config:set mqtt.server.port=12345
  • firebase functions:config:set mqtt.server.host=mqtt://mxx.cloudmqtt.com
  • firebase functions:config:set mqtt.server.user=username
  • firebase functions:config:set mqtt.server.password=password
  • firebase functions:config:set access.api_key=secretapikey

You should generate a unique access.api_key, then add it to dialogflow fulfillment as header "api_key"

Deploy

After you configure your vars, you can then deploy:

$ firebase deploy

Usage

Once you deploy you will get a URL: https://us-central1-mqtttest.cloudfunctions.net/post

You can use this url as dialogflow webhook:
