spray Bus Time Alerter

This project polls the BusTime api for when a bus is within range of a stop and sends an SMS text. It uses Spray and Akka for the endpoints and logic. SMS are sent using TextBelt

Follow these steps to get started:

  1. The following configuration settings are passed to the application by environment variables. They can also be set explicitly in the application.conf

  2. BUS_TIME_API_KEY

  3. BUS_STOP_ID

  4. SMS_NUMBER

  5. EXPRESS_BUS_LINE (this is optional if an express bus also visits the stop)

  6. Change directory into your clone:

     $ cd my-project

  7. Launch SBT:

     $ sbt

  8. Start the application:

     > re-start

  9. Browse to http://localhost:8080

  10. Stop the application:

     > re-stop

To run on a raspberry pi (requires jvm installed. For reasons I did not look into I had trouble running it with Java8):

  1. Create assembly jar:

     $ sbt assembly

  2. Copy created jar file to the raspberry pi

  3. Set above environment variables if not explicitly specified in application.conf

  4. Start the application:

     $ java -Xss1M -Xms64M -jar spray-bus-alerter-assembly-0.1.jar

This project was in part inspired by Control Group's work on the MTA kiosks.
