Calls the Metlink API to get updates to services. Then displays cancellations in the last 24 hours on this dashboard

You can see the alerts also being displayed at www.metlink.org.nz/alerts/bus

To tinker with this project, remix it, and set the metlink_api_key environment variable to your own API key (free registration necessary).

TO DO:

• Determine what percentage of route's services cancelled
• Highlight new cancellations for a few seconds
• Sound notification of cancellations?

DONE:

• Allow filtering by service, or type of service (train/bus)
• STORE data in DB, and return in addition to data being returned by API
• UPSERT data into database to record reversed cancellations
• EMIT cancellations using sockets to update clients without needing to refresh
• Display graph of hourly cancellations over last 24 hours - or perhaps current day?
• Correct ever increasing counter from emits that doesn't reflect data dropping off the 24 hour window
• Do filtering of what constitutes a cancellation on client side
  • This should help handle cancellations being reversed
• Prevent emitting of updates causing duplicates in graph
• Add sequence to allow clients to detect missed emit and reload
• Display dashboard of number of cancellations today, and last 5 or 7 days.
