NotifyWA app and supportive infrastructure
The NotifyWA app is a native app available for iOS and Android that allows users to subscribe to emergencies published by Emergency WA RSS feeds (note this app is not endorsed by DFES)
Using entirely serverless features of AWS, it costs a few dollars a month to maintain in hosting costs
The serverless backend is explained below:
- A lambda function is invoked once per minute
- The function fetches the latest alerts from the Emergency WA RSS feed
- A primary key of the alert (a hash of the incident number and publish date) is compared to existing alerts in DyanmoDB
- New or updated alerts are then converted to push notifications and sent to subscibring users via the app
Native app development for both iOS and Android was performed using the Flutter framework
This allowed rapid time to market and an easy to test and verify experience for both distinct native experiences
The app is available on iOS and Android using the links below
