BandonFEWS-Serverless

A Serverless AWS Lambda function that runs every 15 minutes, checks the Bandon river level at http://www.bandonfloodwarning.ie/ and saves it to Google Fusion Tables.

Setup

(Assuming you have your AWS access credentials already setup)

git clone git@github.com:conoro/bandonfews-serverless.git
cd bandonfews-serverless
npm install -g serverless
npm install
serverless deploy

Notes:

1. You can also invoke it manually by accessing the GET URL returned by the successful serverless deploy
2. You can check manually invoked logs with:

serverless logs -f check

and Cron logs with

serverless logs -f cron

3. If you make minor changes to just the function code, you can do a quick re-deploy with:

serverless deploy function -f check

4. Change FUSIONTABLES_ID in serverless.yml to use this code with your own Fusion Table

5. This code now uses JWT-based auth for simplicity. Here's how to setup for yourself:

   • See here: https://github.com/google/google-api-nodejs-client/
   • And here: https://github.com/google/google-api-nodejs-client/blob/master/samples/jwt.js
   • Go to https://console.developers.google.com/ and create a new project
   • Go to https://console.developers.google.com/apis/library and search for Fusion Tables
   • Enable it for your project
   • Go to https://console.developers.google.com/iam-admin/serviceaccounts/project
   • Click Create Service Account
   • Give it a name and click "Furnish a new private key" and select JSON
   • Ignore Role and Delegation
   • Note the Service Account ID Email address
   • Click Create and it'll start downloading the JSON Key file.
   • Once you get the JSON key file, save it in the project dir as jwt_key.json (do not lose it or leak it!)
   • Add the Service Account ID email as a "Writer" in the sharing settings for your Fusion Table
   • You can now easily read/write to your table without any of the OAuth2 faffing around.
