Setting up the Node.js application

1. Clone/Download zip of repository.

2. Extract content of the zip.

3. Open cmd to run the following code -

cd "folderpath where zip is extracted"
npm install

4. After the installation, run -

npm start

Setting up the .env file

1. You need to register for google geoencoder api from here - https://developers.google.com/maps/documentation/geocoding/get-api-key?authuser=1

Copy the API KEY in the .env file.

2. You also need to have a bluemix account and should have credentials for the Weather API. You can get it from here - https://console.bluemix.net/catalog/services/weather-company-data

Copy the Username and Password of the SERVICE (as shown in image) in the .env file.

Setting up the ngrok

1. In Google Actions, you need an endpoint so that it can connect to your app locally. For this we will install ngrok. Download from here - https://ngrok.com/download

2. Run your app using npm start as explained above in Setting up the Node.js application.

3. Open another terminal and run the following command -

ngrok http 8080

8080 is the port number on which your Nodejs app is running.

4. Copy the Forwarding domain from the ngrok terminal. E.g. Your domain would look something like - https://c90db8b2.ngrok.io

Paste it in the Fulfillment Webhook Configuration.

The final endpoint will be - https://c90db8b2.ngrok.io/weather
