Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

How it works?

In every xx minutes, this lambda function will call an API provided by EPA. This API provides the details of all environment monitoring sites with the latest health advice. This lambda function will dynamically add and remove the monitoring sites, the features of arcGIS layer.

Prerequisites

1. The app can be deploy as standalone NodeJS web app or as a AWS lambda function. To deploy to AWS Lambda, use Serverless

Installing

npm install

Credentials and Registering your App

Finally, update /routes/routes.js to contain your client ID and secret (and portal URL if not ArcGIS Online):

const client_id = 'xx';
const client_secret = 'xx';

Deploy to AWS Lambda

sls deploy

Running the Lambda function offline

sls offline start

Manually trigger AWS Lambda function

sls invoke -f app

To run as a NodeJS app

Comment out the Serverless handle and uncomment the local server part in /index.js

// module.exports.handler = serverless(app);

// USE THIS FOR LOCAL SERVER
var server = app.listen(3000, function() {
  console.log('app running on port.', server.address().port);
});
